SaferWood: Let Nature help you save energy.
When it comes to insulating a home, no other roofing material outperforms Western Red Cedar shakes and shingles. Cedar shakes and shingles could provide up to 20 percent in savings on heating and cooling costs, according to the University of Texas study, "A Comparative Study of the Thermal Characteristics of Cedar and Asphalt Roof Structures". Cedar has more than twice the insulating value of asphalt shingles, four times that of fiber-cement composites, and five times that of slate.
Their natural insulation factors help keep homes cooler in the summer and warmer in the winter. When applied using correct ventilation and insulation techniques, shakes and shingles can provide some of the best energy savings in steep slope roofing products.
