I got 6 estimates, 4 wanted to use and only use BP and IKO, of which IKO asphalt shingles with a 25 yr warranty lasted only 17. Google IKO class action. Lemay roofing was slightly higher but this was with better underlayment, proper valley flashing, a through the roof bathroom vent vs soffit, the only company to notice these better requirements/methods. Work happened on time but was delay by the supplier for finish work. I used Owens Corning shingles in a 3D style. They look great. The workers were professional, on time and carefull of the finished work. Yes you can damage your just layed shingles.
The estimate and other items to add was very well done, no delay to get it unlike others, even in prime roofing season.
I recommend them over others I got estimates from, they knew what they were talking about, the OC shingles should be more reliable. But always get more than one estimate. The first roofer and his estimate was at a loss why I got others after him.
Good work guys.
