According to the US Department of Energy, up to 45% of a home’s energy loss is through the attic. Westshore Roofing, Inc. will inspect the insulation in your attic, to see if it meets the levels recommended for your area. Insulation is measured in R-values—the higher the R-value, the better your roof will resist the transfer of heat. The Department of Energy recommends ranges of R-values based on local heating and cooling costs and climate conditions in different areas of the nation. The Department of Energy recommendations for the Bay Area is a minimum of R30 (11 inches of fiberglass or rock wool or 8 of cellulose).
