"From the historic homes beneath the Flatirons to the newest builds out toward Gunbarrel β Thomsen Roofing has been Boulder's hometown roofer since 1985. Forty years, one standard, done right."
Boulder is unlike anywhere else in Colorado — a city where the Rocky Mountains meet the high plains, where historic Victorian homes sit a few blocks from cutting-edge modern builds, and where homeowners genuinely care about doing things the right way. Roofing here takes a contractor who understands the local climate, the architecture, and the homes themselves. Thomsen Roofing & Restoration Services is locally owned and operated right here in Boulder, on the city's north side. Owner Scot Thomsen has been Boulder's hometown roofer since 1985, and four decades later he's still hands-on from the first inspection to the final walkthrough — which is exactly why more than 90% of our business comes from referrals.
Tucked against the dramatic backdrop of the Flatirons and the foothills of the Rockies, Boulder's neighborhoods each bring their own character and their own roofing needs. The tree-lined streets of Mapleton Hill and University Hill are home to century-old Victorians and historic bungalows with steep pitches, original details, and the kind of complex rooflines that reward experience. North Boulder (NoBo) blends established homes with newer infill construction. Newlands, Wonderland Lake, and the neighborhoods along the foothills sit closest to the open space and the weather that rolls off the mountains. Out east toward Gunbarrel and along the Diagonal Highway, newer subdivisions feature the kind of homes where proper installation and a valid manufacturer warranty pay off years down the road. From the historic downtown core around Pearl Street to the homes near the University of Colorado campus, Scot has worked on Boulder roofs of every era and style — and that range of experience matters when your roof has its own quirks.
Boulder's character runs deep: the iconic Pearl Street Mall, the trails of Chautauqua Park beneath the Flatirons, CU Boulder and its Folsom Field, the city's renowned commitment to open space and the outdoors, and a community that takes real pride in its homes and its environment. Many homes near the historic core and the older established neighborhoods are decades old — some dating back to Boulder's founding era — and that history brings genuine charm along with roofing systems, framing, and details that deserve a contractor who knows what to look for. Thomsen's commitment to recycling roofing debris and doing clean, responsible work fits right in with how Boulder homeowners think.
Here's the reality every Boulder homeowner needs to understand: the Front Range is one of the most demanding roofing environments in the country. Boulder sits at the western edge of "Hail Alley," and damaging hailstorms are an annual threat, not an occasional one — a single storm can bruise shingles, strip granules, and leave hidden damage that turns into leaks down the road. Heavy winter snow loads and the freeze-thaw cycle drive ice dams that force water up under shingles, while Boulder's notorious downslope windstorms — with gusts that can exceed 100 mph coming off the foothills — lift and tear shingles off roofs that weren't installed correctly. Add the intense high-altitude sun that bakes asphalt shingles nine months a year, and you have a climate that punishes any roof that wasn't built and ventilated properly. This is exactly why Thomsen is big on ventilation: in this climate, 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 Boulder homeowners choose Thomsen Roofing & Restoration Services. You get a GAF-certified, licensed and insured roofing contractor with 40 years of hands-on Boulder experience, an owner who's personally on every job, a comprehensive attic ventilation assessment included on every project, all flashings and pipe boots replaced (never reused), premium materials, a strong workmanship warranty, and the manufacturer warranty kept valid by the ventilation work other roofers skip.

Answers to the most common questions Boulder homeowners ask before scheduling their free roof estimate.
Boulder's intense high-altitude sun, heavy snow loads, and freeze-thaw cycle make proper attic ventilation critical. Most manufacturers won't honor their shingle warranties without it, and poor ventilation drives up energy bills, shortens roof life, and worsens ice dams in winter. Thomsen is big on ventilation because in this climate it's the difference between a 10-year roof and a 30-year roof.
Yes. Boulder sits in Hail Alley, and damaging storms are an annual threat. After a hailstorm, we provide a thorough free inspection, document the damage the way adjusters expect, and can meet your adjuster on-site. We guide you through the entire insurance claim process from inspection to a completed, code-compliant restoration. See our Hail & Insurance Restoration page for details.
Absolutely. Homes in Mapleton Hill, University Hill, and the historic neighborhoods near downtown can be a century old or more, with steep pitches, original flashing details, and complex rooflines. Scot's 40 years of Boulder-specific experience equip him to spot these older-home vulnerabilities, recommend the right approach, and deliver workmanship worthy of the home's character.
Boulder's downslope windstorms can bring gusts exceeding 100 mph off the foothills, and they routinely lift and tear shingles — especially on roofs that weren't installed correctly with proper fastening and sealing. A properly installed roof with quality materials and correct nailing patterns holds up far better. If wind has lifted or torn shingles, our repair team can re-secure and replace what's damaged before the next storm.
