               BUILDING MATERIALS CORPORATION OF AMERICA ANNOUNCES
               ---------------------------------------------------
                              THIRD QUARTER RESULTS
                              ---------------------


         Building Materials Corporation of America ("BMCA" or "the Company")
announced today third quarter of 2006 net income of $17.1 million compared to
net income of $21.0 million in the third quarter of 2005. The decrease in third
quarter 2006 net income was primarily attributable to lower income before
interest expense and income taxes and slightly higher interest expense.

         Income before interest expense and income taxes in the third quarter of
2006 was $43.3 million compared to $48.9 million in the third quarter of 2005.
Income before interest expense and income taxes in the third quarter of 2006 was
positively affected by increased net sales of both residential and commercial
roofing products, which was more than offset by higher raw material costs,
including asphalt, and higher selling, general and administrative expenses
mostly due to higher distribution costs, primarily resulting from a rise in fuel
prices.




                                   -continued-

         Interest expense for the third quarter of 2006 increased to $15.8
million from $15.0 million for the third quarter of 2005 primarily due to higher
average borrowings and a higher average interest rate.

         Net sales for the third quarter of 2006 reached $530.3 million, a 6.9%
increase over third quarter of 2005 net sales of $496.3 million, with the
increase due to higher net sales of both residential and commercial roofing
products. The increase in net sales of residential roofing products primarily
resulted from higher average selling prices, partially offset by lower unit
volumes, while the increase in net sales of commercial roofing products was
driven by higher unit volumes and higher average selling prices.

                            FIRST NINE MONTHS RESULTS
                            -------------------------

         For the first nine months of 2006, BMCA announced net income of $47.6
million compared to net income of $52.4 million for the first nine months of
2005. The decrease in the net income for the first nine months of 2006 was
primarily attributable to lower income before interest expense and income taxes,
partially offset by lower interest expense.

         Income before interest expense and income taxes for the first nine
months of 2006 was $123.2 million compared to $132.0 million for the first nine
months of 2005. Income before interest expense and income taxes for the first
nine months of 2006 was positively affected by increased net sales of both
residential and commercial roofing products and a decline in other expense, net,
which was more than offset by higher raw material costs, including asphalt,
higher energy costs and higher selling, general and administrative expenses
mostly due to higher distribution costs, primarily resulting from a rise in fuel
prices.

         Interest expense for the first nine months of 2006 decreased to $46.4
million from $47.5 million for the first nine months of 2005, primarily due to
lower average borrowings.



                                   -continued-

         Net sales for the first nine months of 2006 reached $1,571.2 million, a
6.7% increase over the first nine months of 2005 net sales of $1,472.8 million,
with the increase due to higher net sales of both residential and commercial
roofing products. The increase in net sales of residential roofing products
primarily resulted from higher average selling prices, and the increase in net
sales of commercial roofing products was driven by higher average selling prices
and higher unit volumes.

                                  OTHER MATTERS
                                  -------------

November 2006. The Amended and Restated $450 million Senior Secured Revolving
Credit Facility has a final maturity date of September 28, 2011. The Company
