Can a GALVALUME SSR be installed over an old flat built-up roof?

A GALVALUME SSR is an ideal system for retrofit roofing. Its light weight makes it suitable for retrofit applications over any old, leaking, conventional, nonmetallic roof system. Retrofitting is accomplished by installing to the existing roof structure a light weight sub-framing system, generally made with light structural steel sections, that provides a minimum ¼:12 slope for the new GALVALUME SSR. By installing the roof directly over the existing nonmetallic roof, costly and time-consuming tear-offs are eliminated, and activities inside the building can continue without interruption.
