What Our Clients Say


John K.

"First, I want to say how pleased we are with the work that was done.  The workers were pleasant, hardworking and skilled. They did a fabulous job of cleaning up. We literally had nothing to do, except enjoy our new roof. We also appreciate the attention that was given to a few issues (raccoon attempts to enter the roof, signs of mold, and venting from bath and kitchen fans). It makes us feel much better knowing that these have been dealt with properly.  We were pleased to pass your name on to a friend who is looking for a roofing company."
