             BUILDING MATERIALS CORPORATION OF AMERICA ANNOUNCES
                       FIRST QUARTER OPERATING RESULTS



         Wayne, NJ -- Building Materials Corporation of America ("BMCA" or "the
Company"), announced today first quarter of 2003 net income of $3.6 million
compared to net income of $2.9 million in the first quarter of 2002,
representing an increase of 24.1%. The increase in first quarter of 2003 net
income was primarily attributable to lower other expenses.

         Operating income in the first quarter of 2003 was $20.7 million
compared to $20.6 million in the first quarter of 2002. Operating results were
positively effected by higher net sales of both residential and commercial
roofing products together with lower manufacturing costs, offset by higher raw
material costs, principally asphalt due to higher crude oil prices and limited
asphalt availability, higher energy costs and increased selling, general and
administrative expenses.

         Net sales for the first quarter of 2003 reached $338.9 million, a 6.1%
increase over first quarter of 2002 net sales of $319.3 million, with the
increase primarily due to higher unit volumes and higher average selling prices
of both residential and commercial roofing products.

         Interest expense for the first quarter of 2003 decreased to $13.5
million from $13.7 million for the same period in 2002, primarily due to lower
average borrowings and a lower average interest rate. Other expense net, was
$1.6 million for the first quarter of 2003 compared with $2.3 million for the
same period in 2002.






                                 OTHER MATTERS


         During the first quarter of 2003, the petroleum industry strike in
Venezuela continued to impact the asphalt supply for the U.S. roofing industry.
The tightness in supply of asphalt has resulted in significant asphalt cost
increases. The Company believes that the continued geo-political tensions and
seasonal increases in demand for paving asphalt may further impact asphalt
supplies and pricing in the short-term. With the strength of our manufacturing
operations which allows BMCA to use many types of asphalt, the Company has been
able to secure alternative sources of supply of asphalt and, as a result,
believes the asphalt market conditions will not have a significant impact on
future sales, although no assurances can be provided in that regard.

         To offset these and other petroleum based cost increases, the Company
announced and implemented multiple price increases during the first and second
quarters of 2003. The Company will attempt to pass on future additional
unexpected cost increases from our suppliers as needed; however, no assurances
can be provided that these price increases will be accepted in the marketplace.
