"From historic downtown Frederick to the fast-growing Carbon Valley subdivisions spreading across the plains — Thomsen Roofing brings four decades of Front Range experience to every Frederick home. Since 1985."
Frederick anchors the Carbon Valley in southwest Weld County, a community that has grown rapidly from its coal-mining and farming roots into one of the most active new-home markets on the northern Front Range. Thomsen Roofing & Restoration Services serves Frederick homeowners from our base in nearby Boulder, with owner Scot Thomsen personally on every job. From the older homes and brick character of historic downtown Frederick near Tipple Park, to the booming master-planned subdivisions like Wyndham Hill and the neighborhoods spreading along the I-25 corridor toward Firestone and Dacono, Scot has roofed homes throughout the Carbon Valley — which is why more than 90% of our business comes from referrals.
Frederick's explosive growth means thousands of newer homes built over the past two decades, and many are now reaching the age where original builder-grade roofs start showing their limits — especially after a hard hail season. Frederick sits squarely in "Hail Alley," and its wide-open setting on the eastern plains means it takes the full brunt of severe storms and the region's powerful winds with little to slow them down. Add heavy snow loads, the freeze-thaw cycle that drives ice dams, and the intense high-altitude sun that bakes shingles most of the year, and you have a climate that punishes any roof not built and ventilated correctly. This is why Thomsen is big on ventilation — proper attic airflow is the difference between a roof that lasts 10 years and one that lasts 30, and most manufacturers won't honor their warranties without it.
That's why Frederick homeowners choose Thomsen Roofing & Restoration Services. You get a GAF-certified, licensed and insured contractor with 40 years of Front Range experience, an owner on every job, a comprehensive attic ventilation assessment on every project, all flashings and pipe boots replaced (never reused), premium materials, and a strong workmanship warranty. From roof replacements and standing-seam metal roofing to hail and insurance restoration, honest repairs, and seamless gutters, one trusted local crew handles everything that protects your Frederick home. When you're protecting your biggest investment, local expertise matters — and Scot has been bringing it to Front Range roofs since 1985.

Answers to the most common questions Frederick homeowners ask before scheduling their free roof estimate.
Possibly. Frederick's rapid Carbon Valley growth means many homes were built with builder-grade roofs over the past 10–20 years — and those are now reaching the age where, especially after Hail Alley storms, they start to fail. A free inspection tells you honestly whether you need a repair, a replacement, or simply have good years left. We never recommend unnecessary work.
Yes. Frederick sits in Hail Alley, and its open plains setting takes the full brunt of severe storms. We provide a thorough free inspection, document the damage the way adjusters expect, and can meet your adjuster on-site, guiding you from inspection to a completed restoration.

Frederick's intense high-altitude sun, snow loads, and freeze-thaw cycle make proper attic ventilation critical. Most manufacturers won't honor their shingle warranties without it, and poor ventilation raises energy bills and shortens roof life. Thomsen is big on ventilation because it's the difference between a 10-year roof and a 30-year roof.
