EX-99.1

                                                                    Exhibit 99.1

      ElkCorp Reduces Outlook for its Fourth Quarter and Fiscal Year 2005;
           Expects Record Earnings per Diluted Share for Fiscal 2005;
                 Favorable Roofing Market Expected to Continue;
              Expects Double Digit Earnings Growth for Fiscal 2006

     DALLAS--(BUSINESS WIRE)--June 22, 2005--ElkCorp, (NYSE:ELK), announced
today its revised outlook for its fourth quarter and fiscal year ending June 30,
2005. The company expects earnings per diluted share from continuing operations
for the fourth quarter to be in the range of $0.31 to $0.33, and for fiscal 2005
to be in the range of $2.09 to $2.11, down approximately $0.37 per diluted share
from the most recent guidance of $2.46 to $2.49 per diluted share. The projected
earnings per diluted share from continuing operations for fiscal year 2005 are
approximately a 40% improvement over the $1.51 per diluted share reported for
fiscal year 2004. The results exclude the gain from the divestiture of Ortloff
Engineers, which was sold during the quarter and will be accounted for in
discontinued operations. Consolidated net income for fiscal year 2005 is
expected to be in the range of $2.31 to $2.33 per diluted share, which is a
significant improvement over the $1.03 reported for fiscal year 2004.
     Although expectations for the fourth quarter are not at the levels the
company had anticipated, Elk's earnings expectations for fiscal 2005 are a
substantial improvement over the prior fiscal year. The company stated it also
expects double digit earnings growth for fiscal 2006 fueled by longer than
anticipated hurricane demand in Florida, price increases to assist in offsetting
rising raw material and transportation costs, the increased utilization of added
capacity at the composite lumber facility, solidified relationships with a
distrib utor and a major OEM in the transportation industry and new composite
leadership.
     The estimates for the quarter and fiscal year were impacted by challenges
in the composite lumber business. These issues are expected to impact operating
income by approximately $4.5 million or $0.14 per diluted share. In addition
higher costs and slightly lower shingle volumes than originally anticipated, are
expected to have an impact of approximately $7.9 million or $0.23 per diluted
share.
     Shingle and accessory volume is expected to be down from the company's
original expectations, impacting operating income approximately $4.0 million or
$0.12 per diluted share, primarily due to a production slowdown at its
Myerstown, PA facility because of an equipment failure in the granule storage
system and lower production rates at the Tuscaloosa facility. The granule
storage system problem at the Myerstown facility reduced production to
approximately 90% of capacity; however, the quality of the shingles produced at
this facility has not been affected. The company will pursue claims for full
recovery of damage and lost income from insurers and contractors but recoveries
are subject to uncertainties. Elk anticipates the Myerstown plant to be back to
full capacity sometime during the first quarter of fiscal 2006. Lower volumes in
Tuscaloosa were not due to declining demand but to unanticipated maintenance
downtime. While the downtime was unanticipated, it was not unusual given the
rapid pace of the production and the escalated time table for ramping this
facility to initial rated capacity. Elk expects this facility to continue to
ramp up production in the future but at a slower rate since achieving initial
rated capacity in the third fiscal quarter.
     During the quarter, the company also faced higher than anticipated costs
for freight, raw material and operating expenses, which are expected to have a
negative impact on operating income of approximately $3.9 million or $0.11 per
diluted share. Freight costs were impacted by continued price increases and
higher cost shipping alternatives needed to support the Florida demand.
Manufacturing, selling and G&A expenses were also above the original forecast
for the quarter. Selling expenses are expected to decline from the fourth
quarter levels which include marketing and advertising expenditures from the
consumer marketing campaign launched in the quarter. Asphalt costs also impacted
the quarter due to a more rapid increase than anticipated. In an effort to
offset these costs, Elk has issued a 6-10% price increase on its roofing
products effective June 6, 2005.
     The company's composite lumber business has remained a challenge. The most
significant impact to the composite business was the delay in non-decking
revenues due to customer specification issues and an inventory write-down of
approximately $1.5 million. Products for non-decking applications were
manufactured based on initial specifications and inventories were built to cover
customer's initial projected sales requirements. However, during the final
testing phase of these products, it was apparent the formulations and
specifications required further adjustments. Elk is making the necessary
adjustments to these products and expects revenue generation to begin in the
second quarter of fiscal 2006 with additional products being added in the third
fiscal quarter. The company believes that the recent organizational
restructuring in this platform should alleviate similar product development
issues going forward. The product development process is now under the direct
control of the newly named Executive Vice President, Tim Machelski, and
additional process controls have been added in both the sales and research and
development to ensure customer specifications are met.
     Elk believes changes in the organizational structure at the executive level
and in the product development area have been integral in the recent successes
in the non-decking product line. During the quarter the company has taken
initial orders from a distributor and a major OEM in the transporation industry
for its non-decking products. Revenues from these orders are expected to begin
in the second fiscal quarter of 2006.
     Sales in the decking portion of the composite lumber business continued to
rise. Elk saw revenues double in the previous quarter and expects them to double
in the fourth quarter as well. Sales in the decking business would have been
higher in the quarter but were constrained by the ICC code approval process,
some unanticipated product returns in the quarter resulting from additional
product that was not consistent with the current formulation and product color
variations. The color variation experienced with mixing of new and old
production has been alleviated with all the decking lines now operational at the
new facility. Despite the unanticipated returns, substantial progress toward
achieving profitability has been made in this business line. Distribution has
increased to approximately 100 locations throughout the U.S. and Canada. With
the combination of the overall progress seen in the decking portion of the
business, the current non-decking relationships and those on the horizon, Elk
now expects to return to profitability in the composite lumber platform by the
end of the third quarter of fiscal 2006.
     "The fourth quarter remained challenging due to the production slow-down at
our Myerstown facility, lower than forecast production at Tuscaloosa and the
slower ramp up of the non-decking portion of our composite lumber business.
However, we believe the progress in the composite business combined with
continued strong demand for roofing positions us well for growth in the coming
quarters and throughout fiscal 2006," said Thomas Karol, chairman and chief
executive officer of ElkCorp. "Roofing related demand remains strong with a
healthy backlog of orders in all markets, with the exception of the West that
has been impacted by heavy rains. Additionally, after further review of the
Florida market, we now anticipate the storm demand will continue through July
2006 compared to our original projection that the demand would only last
throughout the remainder of calendar year 2005. During this period, we also
expect the laminated market to continue to grow throughout the majority of the
country. Over the last 12 months, excluding the demand generated in the Florida
market, the total laminated market has grown 11% compared to the previous
12-month period. The overall market growth is expected to maintain favorable
market conditions as the excess hurricane demand in Florida trails off."
     Mr. Karol concluded, "We believe that the new initiatives available in the
composite business combined with a positive roofing environment and our new
innovative products should position us well for fiscal 2006 and beyond."
     The company has scheduled the release of its fourth quarter and fiscal year
2005 actual results on Monday, August 8, following the close of the market, and
a conference call on August 9, 2005, at 11:00 a.m. EDT to further discuss its
earnings and operations for the fourth quarter and fiscal year 2005 as well as
expectations for its first quarter and fiscal year 2006. Investors and other
interested parties may participate in the live audio webcast by visiting the
