The concept of coated steel roofing materials was developed over 50 years ago in England as a result of the British using tar and sand to camouflage galvanized bunkers from the German pilots during World War II. The original product’s composition was quite different from the advancements of today as it incorporated a galvanized steel core and crushed river rock embedded in an asphalt base.

Today, Metals USA Building Products incorporates the latest technology to enhance the Gerard and Allmet stone coated steel roofing product’s performance for the rigorous and varied climates around the world. These innovations, including a weather resistant Galvalume steel base with an ultraviolet resistant acrylic, add superior performance characteristics. It is these characteristics which allow Metals USA to offer a lifetime warranty across the various Gerard and Allmet product lines in a wide variety of colored, granular finishes.

The product is offered in distinct profiles that are designed to replicate time honored traditional roofing materials such as, concrete tile, Spanish tile, wood shakes, and shingles. Durable, lightweight, energy efficient, hail resistant, fire resistant, and able to withstand hurricane strength winds makes stone coated steel the best choice when deciding on a new or replacement roof.

Gerard and Allmet roofing systems are manufactured to meet or exceed the world’s highest standards for roofing products, and will comply with virtually all the major model-building codes.

Consumers and businesses alike are turning to energy efficient and more durable building materials to prolong the life of their investments. Recently, a local dental office in the historic section of downtown Rochester, N.Y., decided to make that investment. Owners and tenants of historical buildings are concerned with the preservation and the effects of time on the buildings structures. The roof is a very critical component for protecting a home or building from the elements and the selection of an Allmet stone coated steel roof was an easy decision for Rosen/Pitcher Dental of Rochester. Pro Nailer Roofing performed the installation. The Allmet Granite Ridge Shingle was the clear choice for this job because it matched the existing roof and could be installed directly over the existing roof eliminating the need for removal of the old roof. The ability to reroof over an existing roof without removal of the old roof has many benefits. First, installation costs are lower because of not having to pay for old roof removal; second, the old roof will provide an additional layer of protection to your home or building; and finally, you help protect the environment by not having to discard old materials into landfills.
