Many building owners are not aware that roof restoration is an intelligent alternative to roof replacement. Most roofs can be restored for a fraction of the cost of a new roof and can be sustained indefinitely. Urethane and silicone roof coating systems are being used by companies of all sizes to waterproof and cool their buildings and improve their bottom lines.
