Installing over old roofs
Because metal is 1/3 to 1/2 lighter than standard asphalt roofing, it can often be installed over existing roofing, eliminating messy and costly tear-offs.

This photo is of a metal roof installation over cedar shakes.

We do not install metal over more than one layer of existing roofing—and each case invites a different challenge.

    Did you know?

• Metal roofs are made of recycled products and can be recycled yet again. Unlike asphalt, the metal will not decompose.
• Metal roofs are practically maintenance free—just hose them off occasionally.
• Metal roofs not only conserve energy, they protect your home against fire, wind and earthquake damage.
• During a heavy rain, one may hear the raindrops. Typically, metal roofs aren't any noisier than other roofs, if there's an attic or insulated space above.
• Metal roofs come with 30-50 year warranties. Asphalt roofs only last 12 to 20 years. Over time, you'll pay for two asphalt roof installations, where one metal roof would have saved you.
• Most manufacturers offer a limited lifetime warranty on metal roof paint coatings—except in industrial and/or heavy coastal saltwater spray areas.
• In some states, insurance companies offer discounts up to 35 percent to homeowners with metal roofs.
