The TruSlate® System from GAF utilizes real natural quarried slate (rather than synthetic imitations) and a high-tech waterproofing material to produce an affordable, light weight (5 ½ pounds per square foot) roof system for both new construction and remodeling projects. This means you get a real natural slate roof instead of an imitation plastic “not slate” roof.


Gaf Truslate Roof Shingles

The system incorporates 12” x 12” natural slate roof shingles and UnderBlock™ UV and Moisture Barrier, a specially blended high-density polyethylene (HDPE). The natural slate roof shingles are what you see. The HDPE is covered by the slate shingles in the course above, and you don’t see.

TruSlate System Roof Shingles

TrueGrip ™ Battens and Hangers hold the slate shingles and HDPE in place. The stainless steel battens are applied to the roof deck with a power nailer and 1 ¼” coiled stainless steel ring shank nails. The pre-installed hangers are made of spring-hardened, powder-coated stainless steel wire and are virtually invisible from the ground.

TruSlate Premium Roofing System

The broad range of natural slate colors available for the TruSlate® System offers both the option of a roof of one color or a blended combination of colors that creates a truly unique, one of a kind, crafted slate roof.


For applications where weight is a consideration in the selection of roofing materials, the TruSlate® System allows for the selection of a roofing material that has sheltered the world’s most significant buildings for more than a thousand years. Real natural slate!
