KC Spray Foam offers silicone roof coatings & closed cell roofing spray foam. Silicone roof coatings and closed cell roofing foam are self-flashing and seamless. This makes it easy to encapsulate protrusions sticking out of the roof. There are no seams to or fasteners to leak. One of the best features of this system is it can withstand ponding water. No other coating systems will do this!
