I purchased a roof with a 25 year warrenty in March of 1999 and it has leaked since installed. Our ceiling has collapsed twice. I have made numerous attempts to contact Mr.Brewster with no luck or reply. His phone numbers have been disconnected and he uses different business names to hide behind. DO NOT USE THIS MAN'S BUSINESS IT IS A SHAM! If you choose to use his services you'll end up like me having spent $5, 700 on a roof that leaks like a sieve.
