Installing a new roof over an existing roof system is risky and increases the chances of roof problems by roughly 50%. A roof restoration is not considered a second roof and does not pose the same threat as installing a new roof over an existing roof. Plus, a roof restoration typically costs 50-60% less than a complete roof replacement. Our restoration products are seamless, lightweight, 100% waterproof and virtually unaffected by long-term UV exposure, chemical contaminants and ponding water. They are extremely breathable, which allows trapped moisture vapors to escape through the new membrane.
