Multi-ply Roofing

Posted on

Multi-ply roofing systems have a long history of successful, leak-free installations with impressive longevity. Their strength, redundancy, and proven dependability is due to the fact that asphalt is an ideal roofing adhesive, forming a waterproof bond between surfaces. Nothing else compares.

Did you know? There are "cool" reflective Energy Star-compliant coating or cap sheet options available for multi-ply roof systems.

Multiple plies protect with redundancy.

In multi-ply systems, redundant bitumen/felt layers are completely adhered over the entire roof to create a monolithic barrier resulting in a durable, reliable roof.
