St. George's Desert Climate and What It Does to Your Roof
Southern Utah averages over 300 days of sun per year, and that UV exposure breaks down asphalt shingles faster than almost any other region in the country. Add the freeze-thaw cycles that hit elevations above 3,000 feet each winter and the flash flooding that follows monsoon season along the Virgin River corridor, and a roof in Washington County faces conditions most roofing materials are not designed for. Mammoth Builders uses GAF-certified shingles and TPO membranes rated specifically for high-UV, high-thermal-expansion environments. Every installation includes a ventilation assessment to prevent heat buildup that accelerates material degradation from the inside out.
