San Jose Stone-Coated Steel

We install a number of different brand names of stone coated steel roof systems: Gerard, Decra, Metro and SteelRock.

This product consists of a strong, 26 gauge metal armor that has been coated with zincualume corrosion inhibitors, epoxy primers and other protective layers to provide a permanent roof product that will not crack, break or curl. A thick coating or ceramically-fired earth-stone granules are then applied to give lasting beauty that tenaciously resists the harmful effects of sun, wind, rain, hail and snow.

These products are made to emulate the rich look of clay tile or wood shake, but are lighter and more durable. For more information about stone-coated steel installation in San Jose, or other roofing systems, call Westshore Roofing today.


Warranty. 50 year to lifetime manufacturers transferable warranty.

Wind. The best in the industry. 120 mph

Weight. The lightest roofing material around. At only 1 1/2lbs per sq ft, stone coated metal roof systems are up to eight times lighter than clay or “lightweight” concrete tile. The interlocking feature of these products improves the structural rigidity of a home. This is an important consideration when living in an earthquake prone environment.

Fire Rating. Can be installed with either Class A, B, or C rating.

Insulation. Good, Most of these roofs are installed over an elevated batten system. This for allows airflow underneath the roof panels. Metal does not retain heat, unlike asphalt shingles and cools down quickly when the sun goes down.

Installing a radiant barrier directly underneath the wood batten system, blocks 97% of radiant heat from entering the building and reduces attic temperature 25 – 30 degrees.
