"From the historic charm of Old Town Niwot to the country properties and acreage homes along the Diagonal — Thomsen Roofing brings four decades of Front Range experience to every Niwot home. Since 1985."
Niwot is one of the Front Range's true hidden gems — an unincorporated community with a beautifully preserved historic downtown, a strong arts-and-music culture, and a small-town feel that residents fiercely protect. Thomsen Roofing & Restoration Services has served Niwot homeowners since 1985 from our base just down the road in Boulder, with owner Scot Thomsen personally on every job. From the historic storefronts and older homes of Old Town Niwot along Second Avenue, to the established neighborhoods of Niwot proper, to the larger acreage and country properties spread along the Diagonal Highway and out toward Gunbarrel, Scot has roofed homes throughout this community — which is why more than 90% of our business comes from referrals.
Niwot's mix of historic homes and rural acreage properties means roofs of every size and vintage, and they all face the same demanding Front Range climate. Niwot sits squarely in "Hail Alley," where damaging hailstorms are an annual threat that can bruise shingles and strip granules in minutes, and its open setting on the plains east of the foothills means it catches the full force of the region's powerful downslope winds. Add heavy snow loads, the freeze-thaw cycle that drives ice dams, and the intense high-altitude sun, and you have a climate that punishes any roof that wasn't 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 Niwot 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 Niwot 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 Niwot homeowners ask before scheduling their free roof estimate.
Yes. Niwot sits in Hail Alley, and damaging storms are an annual threat. 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. See our Hail & Insurance Restoration page.
Absolutely. Many Niwot homes sit on larger lots and acreage along the Diagonal, sometimes with bigger or more complex roofs. Scot's 40 years of Front Range experience cover homes of every size and style, and every estimate is free, in-person, and honest regardless of the property's scale.
Niwot'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.
Niwot's open setting on the plains catches the full force of downslope winds, which routinely lift and tear shingles — especially on roofs without proper fastening. A properly installed roof holds up far better. If wind has damaged your shingles, our repair team can re-secure and replace what's needed.
