Short Story: Poly Vinyl is a Top-Notch company with a large, and capable crew. They specialize in flat-roofing which was perfect because we really needed someone to come waterproof the flat roof over our kitchen and porch. Long Story: After calling a few places and hearing "We won't be able to do your roof until next year," it was a breath of fresh air when Mike Connelly called us back and said he'd be sending out his brother, Buck to look at our roof. Buck helped us figure out how to turn the whole flat roof into a balcony and sure enough, the membrane they used is walkable and they flashed around the railing posts. Speaking as someone who is very cautious and critical when someone else does work on my house, I am completely impressed with the work that they've done and am very grateful for their knowledge, work ethic (they got a 29x11 area with 13 posts done in just hours!), and politeness and would gladly hire them again for something like this. Included is a picture of our dog totally loving it!
