St. George's Locally Owned Roofing Contractor

25 Years

of Experience

Mammoth Builders Roofing and Restoration has served Southern Utah homeowners and commercial property owners for over 25 years, from our office at 144 W Brigham Road, Unit E6, St. George, UT 84790. We answer the phone 24 hours a day, every day of the week.

We are two things at once, and that combination is rare in Washington County. We are a roofing contractor, installing premium, manufacturer-warrantied roofing systems backed by strong warranty protection. And we are an IICRC-certified restoration contractor, responding 24/7 to water damage, fire and smoke damage, mold, and storm damage with emergency extraction, structural drying, and remediation.

Most restoration companies dry your property out and then hand you off to a general contractor you have to find and schedule yourself. We do the mitigation, the rebuild, and the roof under one contract, and we document the whole claim for your insurance carrier. Over 250 clients served across St. George, Washington City, Hurricane, Santa Clara, and Ivins. Every project starts with a no-cost inspection.

Mammoth Builders Roofing and Restoration EXPERIENCE

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 Roofing and Restoration uses premium architectural 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.
