May 16, 2006

PEABODY, Mass.--(BUSINESS WIRE)--May 16, 2006--Beacon Roofing Supply, Inc. ("Beacon" or the "Company")(Nasdaq: BECN) today announced that its Board of Directors has approved a three-for-two stock split that will be distributed in the form of a 50 percent stock dividend. Beacon's stockholders of record at the close of business on May 31, 2006 will receive one additional share for every two shares of common stock held on that date. Beacon intends to distribute the shares on June 12, 2006. The stock split will increase the number of shares of Beacon common stock outstanding from approximately 29.2 million to approximately 43.8 million.

In announcing the stock split, Robert Buck, Beacon's President and Chief Executive Officer, noted that the decision to split Beacon's stock reflected the Company's continued strong performance as well as its positive outlook for future earnings growth. Beacon recently reported record results for the second quarter and first half of fiscal 2006, which ended on March 31, 2006.

"We believe this stock split will place the market price of Beacon's common stock in a more attractive range for investors," said Mr. Buck. "By increasing the number of shares available for sale to the public, we also believe this action will help increase the liquidity of the Company's common stock," he added.
