Whether a roof-over or a tear-off is done by ACR1.COM, the roof comes with the same strong leak-through warranty. Most local codes will not allow a roof-over if the roof already has 2 roof systems in place. If the roof only has one system in place, a roof-over may be the best alternative. Our system allows us to cut out bad spots and build them up, address drainage issues, add insulation and more. We can give you the best available roof on the market and save you thousands of dollars. A commercial roofing expert can determine your best course of action.
