Item 5.03 Amendments to Articles of Incorporation or Bylaws.

On August 1, 2012, the Board of Directors of Gibraltar Industries Inc. (the “Company”) adopted an amendment and restatement of the Company’s Bylaws to add to the existing Bylaws, a new Article II, Section 12 which allows stockholders to act by written consent and sets forth the procedures that must be followed by stockholders to act by written consent, including requirements that stockholders request the establishment of a record date, information which must be supplied by stockholders who request establishment of a record date for purposes of taking action by written consent, requirements for solicitation of written consents of other stockholders and requirements with respect to the timing of delivery to the Company of executed written consents.

The Company believes the Amended and Restated Bylaws provide stockholders with improved rights. The Company’s Board of Directors previously adopted, and its stockholders approved, at the Company’s Annual Meeting of Stockholders on May 3, 2012, an Amendment to the Company’s Certificate of Incorporation to permit the Company’s stockholders to act by written consent.

The foregoing description of the provisions of Article II, Section 12 is qualified in its entirety by the provisions of Article II, Section 12 of the Amended and Restated Bylaws, effective August 1, 2012, a copy of which is filed as Exhibit 3.1 to this Form 8-K and is incorporated herein by reference.

The registered office and/or registered agent of the Corporation may be changed from time to time by action of the Board of Directors.

Section 2. Other Offices. The Corporation may also have offices at such other places, both within and without the State of Delaware, as the Board of Directors may from time to time determine or the business of the Corporation may require.

ARTICLE II

Meetings of Stockholders

Section 1. Annual Meeting. The annual meeting of the stockholders of the Corporation for the election of Directors and for the transaction of other business shall be held at such time and such place within or without the State of Delaware as shall be determined by the Board of Directors or the Chairman of the Board or the President and stated in the notice of the meeting or in a waiver of notice thereof.

Section 2. Special Meetings. Special meetings of stockholders may be requested or called at any time for any purpose by the Board of Directors, the Chairman of the Board, or the President. Subject to the following provisions of this Section 2, special meetings of the stockholders shall be called by the Board of Directors, the Chairman of the Board, or the President upon written request of stockholders holding in the aggregate twenty-five percent (25%) or more of the total voting power of the outstanding shares of capital stock of the Corporation, unless (i) such request is received by the Board of Directors within the ninety (90) day period immediately preceding an annual meeting or a previously scheduled special meeting of the Corporation’s stockholders; or (ii) the proposed business of the special meeting which has been requested is to vote on any matter or matters previously proposed or voted on by the stockholders of the Corporation at an annual or special meeting of the stockholders and the request to hold the special meeting is received by the Board of Directors within ninety (90) days of such annual or special meeting; or (iii) the notice requesting the meeting does not include the information required by Section 11(b) of this Article II. Notwithstanding anything in the foregoing to the contrary, the Board of Directors shall not be obligated to call a special meeting at the request of the stockholders if the proposed business described in the notice is or could be omitted from such notice or the proxy material for a special meeting pursuant to state law or to any rule or regulation of the Securities and Exchange Commission.

1

The date, time and place of a special meeting of the stockholders called at the request of the stockholders shall be set by the Board of Directors and shall not take place more than one hundred twenty (120) days from the date the request is received, provided such request otherwise satisfies the provisions of this Section 2. A stockholder may withdraw a request for a special meeting at any time by delivering to the Board of Directors a written notice indicating such stockholder’s intent to withdraw his, her, or its request for a special meeting of the stockholders. If, following such a withdrawal by a stockholder of his, her, or its request, the total number of shares of capital stock held by stockholders who have requested a special meeting and have not withdrawn such request is less than twenty-five percent (25%) of the total voting power of the outstanding shares of capital stock of the Corporation, the Board of Directors, in its discretion, may cancel such meeting.

Business transacted at a special meeting requested by stockholders shall be limited to the purpose(s) stated in the request for such meeting, provided, however, that the Board of Directors shall have the authority in its discretion to submit additional matters to the stockholders and to cause other business to be transacted at any special meeting requested by stockholders.

Section 3. Place of Meetings. The Board of Directors may designate any place, either within or without the State of Delaware, as the place of meeting for any annual or special meeting. If no designation is made, or if a special meeting is otherwise called, the place of meeting shall be the principal executive office of the Corporation.

Section 4. Notice. Whenever stockholders are required or permitted to take action at a meeting, written or printed notice stating the place, date, time, and, in the case of special meetings, the purpose or purposes, of such meeting, shall be given to each stockholder entitled to vote at such meeting and to each director not less than 10 nor more than 60 days before the date of the meeting. All such notices shall be delivered, either personally or by mail, by or at the direction of the Board of Directors, the President or the Secretary, and if mailed, such notice shall be deemed to be delivered when deposited in the United States mail, postage prepaid, addressed to the stockholder at his, her or its address as the same appears on the records of the Corporation. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened. Any notice delivered under this Article II, Section 4 may also, at the direction of the Board of Directors, cancel or postpone any previously scheduled meeting of the stockholders of the Corporation upon public notice given ten (10) days prior to the date previously scheduled for such meeting provided that, if the meeting is a special meeting which has been called at the request of the stockholders and has not been cancelled in accordance with Section 2, above, the Board of Directors shall not have the authority to cancel such meeting.

2

Section 5. Stockholders List. The officer having charge of the stock ledger of the Corporation shall make, at least 10 days before every meeting of the stockholders, a complete list of the stockholders entitled to vote at such meeting arranged in alphabetical order, showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least 10 days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting or, if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present.

Section 6. Quorum. The holders of a majority of the outstanding shares of capital stock entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders, except as otherwise provided by statute or by the Corporation’s Certificate of Incorporation (the “Certificate of Incorporation”). If a quorum is not present, the holders of a majority of such shares present in person or represented by proxy at the meeting may adjourn the meeting to another time and/or place. When a quorum is once present to commence a meeting of stockholders, it is not broken by the subsequent withdrawal of any stockholders or their proxies.

Section 7. Adjourned Meetings. The stockholders entitled to vote who are present in person or represented by proxy at any meeting of stockholders, whether or not a quorum shall be present at the meeting, shall have power by a majority of the votes cast to adjourn the meeting from time to time without notice other than announcement at the meeting of the time and place to which the meeting is adjourned. At any adjourned meeting held without notice at which a quorum shall be present any business may be transacted that might have been transacted on the original date of the meeting. If the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the adjourned meeting.

Section 8. Vote Required. When a quorum is present, the affirmative vote of the majority of shares present in person or represented by proxy at the meeting and entitled to vote on the subject matter shall be the act of the stockholders, unless the question is one upon which, by express provisions of an applicable law, the Certificate of Incorporation, or these By-Laws, a different vote is required, in which case such express provision shall govern and control the decision of such question. When a separate vote by class is required, the affirmative vote of the majority of shares of such class present in person or represented by proxy at the meeting shall be the act of such class.

Section 9. Voting Rights. Except as otherwise provided by the General Corporation Law of the State of Delaware or by the Certificate of Incorporation and subject to Section 3 of Article V hereof, every stockholder shall at every meeting of the stockholders be entitled to one vote in person or by proxy for each share of common stock held by such stockholder.

3

Section 10. Proxies. Each stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for him or her by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period.

Section 11. Proposed Business. Except as may otherwise be required by applicable law or regulation or be expressly authorized by the Board of Directors, a stockholder may make a nomination or nominations for director of the Corporation at an annual meeting of stockholders or at a special meeting of stockholders called for the purpose of electing directors or may bring up any other matter for consideration and action by the stockholders at a meeting of stockholders only if the provisions of subsections (a) through (d) hereto shall have been satisfied. If such provisions shall not have been satisfied, any nomination sought to be made or other business sought to be presented by a stockholder for consideration and action by the stockholders at the meeting shall be deemed not properly brought before the meeting, is and shall be ruled by the chairman of the meeting to be out of order, and shall not be presented or acted upon at the meeting.

(a) The stockholder must be a stockholder of record entitled to vote on the date of the giving of notice provided for herein and on the record date for such meeting and must continue to be a stockholder of record at the time of such meeting.

(b) For a nomination to be made or other business to be presented by a stockholder, such stockholder must have given timely notice thereof to the Secretary of the Corporation. To be timely, a stockholder’s notice to the Secretary must be delivered to or mailed and received at the principal executive offices of the Corporation not less than 60 days nor more than 90 days prior to the anniversary date of the immediately preceding annual meeting of the Corporation’s stockholders; provided, however, that in the event that the annual meeting is called for a date that is not within 30 days before or after such anniversary date, notice by the stockholder to be timely must be so received not later than the close of business on the 10th day following the day on which notice of the annual meeting was mailed to the Corporation’s stockholders or public disclosure of the date of the annual meeting was made, whichever first occurs. The notice shall specify (i) the name and address of the stockholder as they appear on the books of the Corporation; (ii) the class or series and number of shares of the Corporation which are beneficially owned by the stockholder; (iii) any material interest of the stockholder in the proposed business described in the notice; (iv) if such business is a nomination for director, each nomination sought to be made, together with the reasons for each nomination, a description of the qualifications and business or professional experience of each proposed nominee and a statement signed by each nominee indicating his or her willingness to serve if elected, and disclosing the information about him or her that is required by the Securities Exchange Act of 1934, as amended (the “1934 Act”), and the rules and regulations promulgated thereunder to be disclosed in the proxy materials for the meeting involved if he or she were a nominee of the Corporation for election as one of its directors; (v) if such business is other than a nomination for director, the nature of the business, the reasons why it is sought to be raised and submitted for a vote of the stockholders and if and why it is deemed by the stockholder to be beneficial to the Corporation; and (vi) if so requested by the Corporation, all other information that would be required to be filed with the Securities and Exchange Commission if, with respect to the business proposed to be brought before the meeting, the person proposing such business was a participant in solicitation subject to Section 14 of the 1934 Act.

4

(c) Notwithstanding satisfaction of the provisions of subsection (b), the proposed business described in the notice may be deemed not to be properly brought before the meeting if, pursuant to state law or to any rule or regulation of the Securities and Exchange Commission, it was offered as a stockholder proposal and was omitted, or had it been so offered, it could have been omitted, from the notice of, and proxy material for, the meeting (or any supplement thereto) authorized by the Board of Directors.

(d) In the event such notice is timely given and the business described therein is not disqualified because of subsection (c), such business (i) may nevertheless not be presented or acted upon at a special meeting of stockholders unless in all other respects it is properly before such meeting; and (ii) may not be presented except by the stockholder who shall have given the notice required by subsection (b) or a representative of such stockholder who is qualified under the law of the State of Delaware to present the proposal on the stockholder’s behalf at the meeting.

Section 12. Action by Written Consent. (a) Subject to the provisions of this Section 12, any action required or permitted under applicable law to be taken at an Annual or Special Meeting of stockholders may be taken without a meeting, without prior notice, and without a vote if the action is taken by the holders of outstanding stock entitled to vote thereon having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of stock outstanding and entitled to vote thereon were present and voted.

(b) In order to be effective the action must be evidenced by one or more written consents describing the action taken, dated and signed by stockholders having, in the aggregate, the requisite number of shares of stock and that would be necessary to authorize or take such action at a meeting at which all shares of stock outstanding and entitled to vote thereon were present and voted. Such one or more written consents must be delivered to the Secretary of the Corporation at the principal executive office of the Corporation. Delivery may be made by hand or by certified or registered mail, return receipt requested. No written consent shall be effective to take the corporate action referred to therein unless, within 60 (sixty) days of the date of the earliest dated valid consent delivered in the manner required by this Section 12, written consents signed by the number of holders required to take the action are delivered to the Secretary of the Corporation by delivery to the Secretary of the Corporation at its principal executive office. Only stockholders of record on the record date shall be entitled to consent to corporate action in writing without a meeting.

(c) Any written consent may be revoked prior to the date that the Corporation receives the required number of consents to authorize the proposed action. No revocation shall be effective unless in writing and delivered to the Secretary of the Corporation at the Corporation’s principal executive office.

5

(d) Without qualification, any stockholder of record seeking to have the stockholders authorize or take any action by written consent shall first request in writing that the Board of Directors fix a record date for the purpose of determining the stockholders entitled to take such action, which request shall be in proper form and delivered to the Secretary of the Corporation at its principal executive office. No action by consent shall be effective to take corporate action referred to therein if such request is received by the Board of Directors within 60 (sixty) days of an annual meeting or a previously scheduled special meeting of the Corporation’s stockholders. No action by consent shall be effective unless the stockholder of record seeking to have the stockholders authorize or take action by written consent has subsequently solicited consents with respect to such proposed action and record date from all holders of outstanding common stock as of the record date for such consents. Within ten (10) days after receipt of a request in proper form and otherwise in compliance with this Section 12(c) from any such stockholder, the Board of Directors may adopt a resolution fixing a record date for the purpose of determining the stockholders entitled to take such action, which date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which date shall not be more than ten (10) days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. If no resolution fixing a record date has been adopted by the Board of Directors within such ten (10) day period after the date on which such a request is received,

(i) the record date for determining stockholders entitled to consent to such action, when no prior action of the Board of Directors is required by applicable law, shall be the first date on which a valid signed written consent setting forth the action taken or proposed to be taken is delivered to the Secretary of the Corporation in the manner described in this Section 12, and

(ii) the record date for determining stockholders entitled to consent to such action, when prior action by the Board of Directors is required by applicable law, shall be at the close of business on the date on which the Board of Directors adopts the resolution taking such prior action.

(e) To be in proper form for purposes of this Section 12, a request by a stockholder for the Board of Directors to fix a record date shall set forth:

(i) As to each Soliciting Person (as defined below), the Stockholder Information, which shall mean: (A) the name and address of such Soliciting Person (including, if applicable, the name and address that appear on the Corporation’s books and records); and (B) the number of shares of the Corporation that are, directly or indirectly, owned of record or beneficially owned (within the meaning of Rule 13d-3 under the 1934 Act) by such Soliciting Persons, except that such Soliciting Person shall in all events be deemed to beneficially own any shares of stock of the Corporation as to which such Soliciting Person has a right to acquire beneficial ownership at any time in the future.

6

(ii) As to each Soliciting Person, any Disclosable Interests, which shall mean (A) any option, warrant, convertible security, stock appreciation right, derivative, swap or other transaction or series of transactions engaged in, directly or indirectly, by such Soliciting Person, the purpose or effect of which is to give such Soliciting Person economic risk similar to ownership of shares of stock of the Corporation, including due to the fact that the value of such option, warrant, convertible security, stock appreciation right, derivative, swap, or other transactions are determined by reference to the price, value or volatility of any shares of stock of the Corporation, or which option, warrant, convertible security, stock appreciation right, derivative swap or other transactions provide, directly or indirectly, the opportunity to profit from any increase in the price or value of shares of stock of the Corporation (“Synthetic Equity Interests”), which Synthetic Equity Interests shall be disclosed without regard to whether (x) the option, warrant, convertible security, stock appreciation right, derivative, swap, or other transactions convey any voting rights in such shares of stock to such Soliciting Person, (y) the option, warrant, convertible security, stock appreciation right, derivative, swap or other transactions are required to be, or are capable of being settled through delivery of such shares of stock or (z) such Soliciting Person may have entered into other transactions that hedge or mitigate the economic effect of such option, warrant, convertible security, stock appreciation right, derivative, swap or other transaction; (B) any proxy (other than a revocable proxy or consent given in response to a solicitation made pursuant to, and in accordance with, Section 14(a) of the 1934 Act by way of a solicitation statement filed on Schedule 14A), agreement, arrangement, understanding or relationship pursuant to which such Soliciting Person has or shares a right to vote any shares of stock of the Corporation; (C) any agreement, arrangement, understanding or relationship, including repurchase or similar so-called “stock borrowing” agreement or arrangement, engaged in, directly or indirectly, by such Soliciting Person, the purpose or effect of which is to mitigate loss to, reduce the economic risk (of ownership or otherwise) of shares of stock of the Corporation by, manage the risk of share price changes for, or increase or decrease the voting power of, such Soliciting Person with respect to the shares of stock of the Corporation, or which provides, directly or indirectly, the opportunity to profit from any decrease in the price value of the shares of stock of the Corporation (“Short Interests”); (D) any rights to dividends on the shares of stock of the Corporation owned beneficially by such Soliciting Person that are separated or separable from the underlying shares of stock of the Corporation; (E) any performance related fees (other than an asset based fee) that such Soliciting Person is entitled to based on any increase or decrease in the price or value of shares of stock of the Corporation, or any Synthetic Equity Interests or Short Interests, if any; (F) if such Soliciting Person is not a natural person, the identity of the natural person or persons associated with such Soliciting Person responsible for the formulation of and decision to propose the business to be brought before the meeting (such person or persons, the “Responsible Person”), the manner in which such Responsible Person was selected, any fiduciary duties owed by such Responsible Person to the equity holders or other beneficiaries of such Soliciting Person, the qualifications and background of such Responsible Person and any material interests or relationships of such Responsible Person that are not shared generally by any other record or beneficial holder of the shares of stock of the Corporation and that reasonably could have influenced the decision of such Soliciting Person to propose such business to be brought before the meeting, and (y) if such Soliciting Person is a natural person, the qualification and background of such natural person and any material interests or relationships of such natural person that are not shared generally by another record or beneficial holder of the shares of stock of the Corporation and that reasonably could have influenced the decision of such Soliciting Person to propose such business to be brought before the meeting; (G) any significant equity interests or any Synthetic Equity Interests or Short Interests in any particular competitor of the Corporation held by such Soliciting Persons; (H) any direct or indirect interest of such Soliciting Person in any contract with the Corporation, any affiliate of the Corporation or any principal competitor of the Corporation (including in any such case, any employment agreement, collective bargaining agreement or consulting agreement), (I) any pending or threatened litigation in which such Proposing Party is a party or material participant involving the Corporation or any of its officers or directors, or any affiliate of the Corporation; (J) any material transaction occurring during the prior twelve months between such Soliciting Person, on the one hand, and the Corporation, any affiliate of the Corporation or any principal competitor of the Corporation, on the other hand; (K) a summary of any material discussions regarding the business proposed to be brought before the meeting (x) between or among any of the Soliciting Persons or (y) between or among any Proposed Person and any other record or beneficial holder of the shares of stock of the Corporation (including their names); and (L) any other information relating to such Soliciting Person that would be required to be disclosed in a proxy statement or other filing required to be made in connection with solicitations of proxies or consents by such Soliciting Person in support of the business proposed to be brought before the meeting pursuant to Section 14(a) of the 1934 Act, including without limitation any of the aforementioned Disclosable Interests held by members of such Soliciting Person’s immediate family sharing the same household; provided, however, that Disclosable Interests shall not include any such disclosures with respect to the ordinary course business activities of any broker, dealer, commercial bank, trust company or other nominee who is a Soliciting Person solely as a result of being the stockholder directed to prepare and submit the notice required by these Bylaws on behalf of the beneficial owner; and

7

(iii) As to the action or actions proposed to be taken by written consent: (A) a reasonably brief description of the action or actions, the reasons for taking such action or actions and any material interest in such action or actions of each Soliciting Person; and (B) the text of the resolutions or consent proposed to be acted upon by written consent of the stockholders.

For purposes of this Section 12, the term “Soliciting Person” shall mean: (i) the stockholder making a request for the Board of Directors to fix a record date and proposing the action or actions to be taken by written consent; (ii) the beneficial owner or beneficial owners, if different from the stockholder, on whose behalf such request is made; and (iii) any affiliate or associate of such stockholder or beneficial owner.

(f) In connection with an action or actions proposed to be taken by written consent in accordance with this Section 12, the stockholder or stockholders seeking such action or actions shall further update and supplement the information previously provided to the Secretary of the Corporation in connection therewith, if necessary, so that the information provided or required to be provided pursuant to this Section 12 shall be true and correct as of the record date for determining the stockholders eligible to take such action and as of the date that is five (5) business days prior to the date the consent solicitation is commenced, and such update and supplement shall be delivered to the Secretary at the principal executive offices of the Corporation not later than five (5) business days after the record date for determining the stockholders eligible to take such action (in the case of the update and supplement required to be made as of the record date), and not later than three (3) business days prior to the date that the consent solicitation is commenced (in the case of the update and supplement required to be made as of five (5) business days prior to the commencement of the consent solicitation).

8

(g) Notwithstanding anything in these Bylaws to the contrary, no action may be taken by the stockholders by written consent except in accordance with this Section 12. If the Board of Directors shall determine that any request to fix a record date or to take stockholder action by written consent (i) was not properly made in accordance with this Section 12, (ii) relates to an item of business that is not a proper subject for stockholder action under applicable law, or (iii) the stockholder or stockholders seeking to take such action do not otherwise comply with this Section 12, then the Board of Directors shall not be required to fix a record date and any such purported action by written consent shall be null and void to the fullest extent permitted by applicable law. In addition to the requirements of this Section 12 with respect to stockholders seeking to take action by written consent, each Soliciting Person shall comply with all requirements of applicable law, including all requirements of the 1934 Act, with respect to such action.

(h) Within 10 days after obtaining authorization by written consent, notice must be given to those stockholders who are not entitled to vote on the action and to those stockholders who have not consented in writing to the action authorized by written consent, even though such stockholders shall have been solicited to approve the action proposed to be taken by written consent as required by Section 12(d) of this Article. The notice shall fairly summarize the material features of the authorized action and, if the action be such for which dissenters’ rights are provided under applicable law, the notice shall contain a clear statement of the right of stockholders dissenting therefrom to be paid the fair value of their shares upon compliance with further provisions of the General Corporation Law of the State of Delaware regarding the rights of dissenting stockholders.

(i) A consent signed under this Section 12 has the effect of a meeting vote and may be described as such in any document.

(j) Whenever action is taken pursuant to this Section 12, the written consent of the stockholders consenting thereto or the written reports of inspectors appointed to tabulate such consents shall be filed with the minutes of proceedings of stockholders.

(k) For purposes of this Section 12, delivery of any request for the establishment of a record date, notice, consent, or other document shall only be deemed to be delivered if by hand, when received by the Secretary of the Corporation, or if by certified mail, return receipt requested, 5 (five) days following deposit in the United States mail, postage prepaid, addressed to the Secretary of the Corporation at the address of the Corporation’s principal executive office.

ARTICLE III

Directors

Section 1. General Powers. The property, business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors.

Section 2. Number, Election and Term of Office. The number of directors shall be established as provided in the Certificate of Incorporation. Except as provided in Section 4 of this Article, each director shall be elected by the vote of the majority of the votes cast with respect to the director at any meeting for the election of directors at which a quorum is present, provided that if the number of nominees exceeds the number of directors to be elected, the directors shall be elected by the vote of a plurality of the shares represented in person or by proxy at any such meeting and entitled to vote on the election of directors. For purposes of this Section, a majority of the votes cast means that the number of shares voted “for” a director must exceed the number of votes cast “against” that director. If a director does not receive a majority of the votes cast, the director shall tender his or her resignation to the Board. The Nominating and Corporate Governance Committee will make a recommendation to the Board on whether to accept or reject the resignation, or whether other action should be taken. The Board will act on the Committee’s recommendation and publicly disclose its decision and the rationale behind it within 90 days from the date of the certification of the election results. The director who tenders his or her resignation will not participate in the Board’s decision. Directors shall hold office until the annual meeting at which their terms expire and until their successors shall be duly elected and qualified, or until their earlier death resignation or removal. Directors need not be stockholders. If, for any cause, the Board of Directors shall not have been elected at an annual meeting, they may be elected as soon thereafter as convenient at a special meeting of the stockholders called for that purpose in the manner provided in these Bylaws.

Section 3. Removal and Resignation. Any director or the entire Board of Directors may be removed at any time, with cause, by the holders of a majority of the shares then entitled to vote at an election of directors. Whenever the holders of any class or series are entitled to elect one or more directors by the provisions of the Certificate of Incorporation, the provisions of this Section 3 shall apply, in respect to the removal with cause of a director or directors so elected, to the vote of the holders of the outstanding shares of that class or series and not to the vote of the outstanding shares as a whole.

Gibraltar’s Net Sales Increase 5% and

Income from Continuing Operations Grows 10% in Second Quarter

Buffalo, New York, August 2, 2012 – Gibraltar Industries, Inc. (Nasdaq: ROCK), a leading manufacturer and distributor of products for building and industrial markets, today reported its financial results for the three and six month periods ended June 30, 2012. All financial metrics in this release reflect only the Company’s continuing operations unless otherwise noted.

Management Comments

“Gibraltar’s net sales increased 5% in the second quarter of 2012. Three percentage points were organic and the balance driven by acquisitions,” said Chairman and Chief Executive Officer Brian Lipke. “The leverage from the sales growth helped contribute to a net income increase of 10%. This improved performance was generated while incurring a less favorable raw material margin and the increased costs of merging our West Coast operations. We expect to complete the consolidation of these West Coast businesses over the next two quarters which bodes well for gradual earnings improvements.”

“From a top-line perspective, this was another solid quarter for D.S. Brown which was acquired April 1^st last year and for sales to customers in the oil and gas and industrial markets,” said Henning Kornbrekke, President and Chief Operating Officer. “Most important, we continued to hold our market share in major product categories, a result of our continuing efforts to provide our customers with new products, innovative marketing programs and outstanding customer service. Additionally, we expect the product lines acquired over the past fifteen months will expand into new markets and channels, adding value to national customers.”

“Several factors affected our profitability in the second quarter,” Kornbrekke said. “We are combining four separate West Coast locations with similar products and market characteristics into an integrated entity with market differentiators that provide benefits to our customers, and our earnings included these costs along with a significant inventory write-down related to this initiative. Additionally, this quarter provided decreased market demand and more competitive conditions in certain product categories while we also benefited from lower SG&A expense.”

19

“Over the longer term, we expect to continue making progress on the strategy we put in place at the beginning of the housing downturn,” said Lipke. “This strategy is to continue reconfiguring the business to offer category leading products and customer service while we maintain continued and improving profitability even at low demand levels in our major end markets. We expect this strategy will position Gibraltar for additional earnings growth as our end markets gradually recover. In addition, our strong balance sheet and strong liquidity position will allow continued acquisition activity to strengthen our existing businesses, broaden and diversify our product offering and provide enhanced growth opportunities. We are continuing to focus on our underlying operations, tightly controlling costs and increasing the margin leverage in our business. Despite persistently weak conditions in our end markets, we continue to expect to deliver stronger financial results in 2012 than we did in 2011.”

Second Quarter Financial Results

Gibraltar’s net sales for the second quarter of 2012 increased 5% to $219.7 million, from $208.8 million for the second quarter of 2011. Net income from continuing operations increased 10% to $7.9 million, or $0.26 per diluted share, compared to $7.2 million, or $0.24 per diluted share, in the second quarter of 2011. The second-quarter 2012 results include after-tax special charges of $0.8 million, or $0.02 per diluted share, resulting primarily from exit activity costs related to business restructuring. Net income for the second quarter of 2011 included after-tax special charges totaling $2.1 million, or $0.06 per diluted share, primarily consisting of exit activity costs and acquisition costs. Excluding these items, second-quarter 2012 adjusted net income was $8.7 million, or $0.28 per diluted share, compared with $9.3 million, or $0.30 per diluted share, in the second quarter of 2011.

Adjusted gross margin for the second quarter of 2012 was 19.5%, a decrease of 360 basis points from the second quarter of 2011. The lower gross margin reflects less favorable raw material costs net of pricing to customers and costs related to acquisition integration in the West Coast region, partially offset by favorable leverage from organic volume growth. Adjusted selling, general and administrative expense for the second quarter of 2012 was $25.4 million, or 11.6% of net sales, compared with $27.3 million, or 13.1% of net sales, a year earlier, primarily reflecting lower compensation expense and maintaining other expense levels in spite of higher sales volume in the second quarter of 2012.

Six Month Financial Results

For the six months ended June 30, 2012, total net sales increased to $411.9 million, from $372.4 million in the comparable 2011 period, an 11% increase that included 4% organic growth. Net income from continuing operations was $9.4 million, or $0.30 per diluted share, compared to $8.7 million, or $0.28 per diluted share, in the comparable period of 2011. The results for the first half of 2012 include after-tax special charges of $2.0 million, or $0.07 per diluted share, for acquisition-related costs and exit activity costs related to business restructuring. Net income for the first six months of 2011 includes after-tax special charges of $3.9 million, or $0.13 per diluted share, for acquisition-related costs, exit activity costs related to business restructuring, and equity compensation declined by Mr. Lipke. Excluding these items, adjusted net income in the first six months of 2012 was $11.3 million, or $0.37 per diluted share, compared with $12.6 million, or $0.41 per diluted share, in the comparable period of 2011.

20

Adjusted gross margin for the first six months 2012 decreased to 19.5%, from 21.2% in the comparable period of 2011. The decrease was primarily due to costs associated with the expanded integration of Gibraltar’s West Coast residential businesses and less favorable raw material costs relative to pricing. Adjusted selling, general and administrative expense for the first six months of 2012 increased 10% to $53.8 million, from $48.9 million a year earlier, reflecting selling, general and administrative expense incurred by acquired businesses. Adjusted selling, general and administrative expenses as a percent of net sales remained unchanged at 13.1% for both six-month periods.

Liquidity and Capital Resources

• Gibraltar’s liquidity increased again to $194 million as of June 30, 2012, a combination of cash on hand of $44 million and availability under the Company’s undrawn revolving credit facility.

• Working capital management continued to be effective, as days of net working capital, which consists of accounts receivable, inventory and accounts payable, were 60 for the second quarter of 2012, compared with 61 days for the second quarter last year.

Outlook

“We have made significant progress in the past few years leveraging improved profitability from Gibraltar’s business, without the benefits of a significant recovery in our end markets,” said Lipke. “Since late 2007 we have essentially reconfigured the business, reduced our annual operating expenses, managed commodity costs more effectively, and reduced our working capital by nearly half. We also rationalized and refocused our business portfolio and our product lines through strategic divestitures and acquisitions.”

“These strategic initiatives have enabled us to drive organic and acquisition-driven volume growth while improving our margins,” Lipke said. “As a result, we have increased Gibraltar’s earnings from continuing operations in an end-market environment that, overall, has been stubbornly resistant to sustained improvement, while generating positive cash flow and strengthening our balance sheet, including reducing our borrowings by nearly half. When our end markets begin meaningful improvement, we are positioned to realize incremental profitability for Gibraltar from sales volume growth and from further portfolio management as we acquire new businesses that take us further up the value chain.”

“Overall, we are optimistic about Gibraltar’s prospects and we look forward to reporting year-over-year improvement in our financial results for 2012,” Lipke concluded.

Safe Harbor Statement

Information contained in this news release, other than historical information, contains forward-looking statements and is subject to a number of risk factors, uncertainties, and assumptions. Risk factors that could affect these statements include, but are not limited to, the following: the availability of raw materials and the effects of changing raw material prices on the Company’s results of operations; energy prices and usage; changing demand for the Company’s products and services; changes in the liquidity of the capital and credit markets; risks associated with the integration of acquisitions; and changes in interest and tax rates. In addition, such forward-looking statements could also be affected by general industry and market conditions, as well as general economic and political conditions. The Company undertakes no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required by applicable law or regulation.

Non-GAAP Financial Data

To supplement Gibraltar’s consolidated financial statements presented on a GAAP basis, Gibraltar also presented certain adjusted financial data in this news release. Adjusted financial data excluded special charges consisting of restructuring primarily associated with the closing and consolidation of our facilities, acquisition-related costs, and surrendered equity compensation. These adjustments are shown in the Non-GAAP reconciliation of adjusted operating results excluding special charges provided in the financial statements that accompany this news release. We believe that the presentation of results excluding special charges provides meaningful supplemental data to investors, as well as management, that are indicative of the Company’s core operating results and facilitates comparison of operating results across reporting periods as well as comparison with other companies. Special charges are excluded since they may not be considered directly related to our ongoing business operations. These adjusted measures should not be viewed as a substitute for our GAAP results, and may be different than adjusted measures used by other companies.

Next Earnings Announcement

Gibraltar expects to release its financial results for the three- and nine-month periods ending September 30, 2012, on November 1, 2012, and hold its earnings conference call later that morning, starting at 9:00 a.m. ET.
