Replacing Wood Shake/Shingle Roofs in the San Bernardino County Mountains
Replace ignitable Roofing with Class A non-organic Fire-Resistant Materials. Participate in a Cost/Share reimbursement program.
Fire protection can involve a variety of changes to your house and property -- changes that can vary in complexity and cost. You may be able to make some changes yourself. But complicated or large-scale changes and those that affect the structure of your house or its electrical wiring and plumbing should be carried out only by a professional contractor licensed to work in your state, county, or city. One example of fire protection is replacing flammable roofing materials with fire-resistant materials. Recent studies have shown that there is a 51% fire risk reduction for homes with Class A non-organic or non combustible roofing material. This is something that most homeowners would probably hire a contractor to do.
Replace Roofing with Fire-Resistant Materials
Some roofing materials, especially old wood shakes/singles, are less resistant to fire than others. When wildfires and brush fires spread to houses, it is often because burning branches, leaves, and other debris buoyed by the heated air are carried by the wind and fall on roofs. If the roof of your house is covered with old wood shake/shingles, you should consider replacing them with fire-resistant materials. In the Mountain Communities of San Bernardino County a non-organic Class A roofing covering is required for all new roofs.
You can replace your existing roofing materials with slate, terra cotta or other types of tile, or standing-seam metal roofing or a Class A asphalt shingle roofing material. Replacing roofing materials is difficult and dangerous work. Unless you are skilled in roofing and have all the necessary tools and equipment, you will probably want to hire a roofing contractor to do the work. Also a roofing contractor can advise you on the relative advantages and disadvantages of various fire-resistant roofing materials.
If you hire a contractor to replace your existing roof covering, you can expect to pay between $3.50 to $5.00 per square foot for asphalt shingle roofs. For example, a house measuring 60 feet by 30 feet will have about 1,800 square feet of roof area. So for this house, an Class A asphalt shingle roof would cost approximately $6,300.00 to $9,000.00. Prices vary depending upon the slope of the roof, roofing material, access, roof angle, the square footage of the roof, etc. Contact your local roofing contractor for specific information on your roof.
