2019 Second Quarter Earnings Call Exhibit 99.2

Disclosure notice This presentation contains information about management's view of the Company's future expectations, plans and prospects that constitute forward-looking statements for purposes of the safe harbor provisions under the Private Securities Litigation Reform Act of 1995. Actual results may differ materially from those indicated by such forward-looking statements as a result of various important factors, including, but not limited to, those set forth in the "Risk Factors" section of the Company's latest Form 10-K. In addition, the forward-looking statements included in this presentation represent the Company's views as of the date of this presentation and these views could change. However, while the Company may elect to update these forward-looking statements at some point, the Company specifically disclaims any obligation to do so, other than as required by federal securities laws. These forward-looking statements should not be relied upon as representing the Company's views as of any date subsequent to the date of this presentation. This presentation contains references to certain financial measures that are not presented in accordance with United States Generally Accepted Accounting Principles (“GAAP"). The Company uses non-GAAP financial measures to evaluate financial performance, analyze underlying business trends and establish operational goals and forecasts that are used when allocating resources. The Company believes these non-GAAP financial measures permit investors to better understand changes in underlying operating performance over comparative periods by providing financial results that are unaffected by cyclical variances that can be driven by items such as investment activity or purchase accounting adjustments. While the Company believes these measures are useful to investors when evaluating performance, they are not presented in accordance with GAAP, and therefore should be considered supplemental in nature. The Company’s non-GAAP financial measures should not be considered in isolation or as a substitute for any items calculated in accordance with GAAP. In addition, these non-GAAP measures may have material limitations and may differ from similarly titled measures presented by other companies. A reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measure can be found in the Appendix as well as Company’s latest Form 8-K, filed with the SEC on May 7, 2019. | www.becn.com

Reconciliation: Adj. Net Income & Adj. EPS | www.becn.com Adjusted Net Income (Loss) is defined as net income that excludes non-recurring acquisition costs, the amortization of intangibles, business restructuring costs, and the non-recurring effects of tax reform. Adjusted net income per share or "Adjusted EPS" is calculated by dividing the Adjusted Net Income (Loss) for the period by the weighted-average diluted shares outstanding for the period. We use Adjusted Net Income (Loss) and Adjusted EPS to evaluate financial performance, analyze the underlying trends in our business and establish operational goals and forecasts that are used when allocating resources.   We believe that Adjusted Net Income (Loss) and Adjusted EPS are useful measures because they permit investors to better understand changes in underlying operating performance over comparative periods by providing financial results that are unaffected by cyclical variances that can be driven by items such as investment activity or purchase accounting adjustments. While we believe Adjusted Net Income (Loss) and Adjusted EPS are useful to investors when evaluating our business, they are not prepared and presented in accordance with United States Generally Accepted Accounting Principles (“GAAP”), and therefore should be considered supplemental in nature. You should not consider Adjusted Net Income (Loss) or Adjusted EPS in isolation or as a substitute for net income and net income per share or diluted earnings per share calculated in accordance with GAAP. In addition, Adjusted Net Income (Loss) and Adjusted EPS may have material limitations and may differ from similarly titled measures presented by other companies.

Reconciliation: AdjUSTED EBITDA | www.becn.com Adjusted EBITDA is defined as net income plus interest expense (net of interest income), income taxes, depreciation and amortization, stock-based compensation, non-recurring acquisition costs, and business restructuring costs. EBITDA is a measure commonly used in the distribution industry, and we present Adjusted EBITDA to enhance your understanding of our operating performance. We use Adjusted EBITDA to evaluate financial performance, analyze the underlying trends in our business and establish operational goals and forecasts that are used when allocating resources. We expect to compute Adjusted EBITDA consistently using the same method each period. We believe that Adjusted EBITDA is a useful measure because it permits investors to better understand changes in underlying operating performance over comparative periods by providing financial results that are unaffected by cyclical variances that can be driven by items such as investment activity or purchase accounting adjustments. While we believe Adjusted EBITDA is useful to investors when evaluating our business, it is not prepared and presented in accordance with United States Generally Accepted Accounting Principles (“GAAP”), and therefore should be considered supplemental in nature. Adjusted EBITDA should not be considered in isolation or as a substitute for net income, cash flows from operations, or any other items calculated in accordance with GAAP. In addition, Adjusted EBITDA may have material limitations and may differ from similarly titled measures presented by other companies.

Reconciliation: Existing Markets OpEx to Adj. OpEx | www.becn.com Adjusted Operating Expense is calculated by removing the impact of non-recurring acquisition costs and amortization of intangibles from existing market operating expense as reported on a GAAP basis. Non-GAAP adjustment totals are detailed as follows: FY19 adjustments are composed of $6.7M of non-recurring acquisition costs and $51.2M of amortization FY18 adjustments are composed of $28.3M of non-recurring acquisition costs and $37.1M of amortization We believe that non-GAAP measures are useful measures because they allow investors to better understand changes in underlying operating performance over comparative periods by providing investors with financial results that are unaffected by cyclical variances that can be driven by items such as investment activity or purchase accounting adjustments. While we believe that that non-GAAP measures are useful to investors when evaluating our business, this information should be considered as supplemental in nature and is not meant as a substitute for the related financial information prepared and presented in accordance with GAAP. You should not consider this measure as a substitute alongside other financial performance measures presented in accordance with GAAP. In addition, non-GAAP measures may have material limitations and may differ from similarly titled measures presented by other companies.
