AfterRoofers in Windsor, CA
Most Windsor roofers are booked solid because the town’s 1990s-2000s housing stock is hitting replacement age all at once, and every homeowner now leads with fire-resistant materials after the 2019 Kincade Fire evacuation. We’re Birchbark Roofing, part of the Cedarwell family since 2000, and we dispatch crews to Windsor from our San Francisco Bay Area office. Call (424) 766-4937 to schedule your free estimate.
Why Windsor Homes Are Different
Windsor incorporated in 1992 and grew fast through large-tract subdivisions built between the mid-1990s and mid-2000s. That means entire neighborhoods share the same 25-year asphalt shingles or concrete tile roofs, the same builder-grade underlayment, and the same flashing details, all reaching end-of-life simultaneously. We see this compression in areas like the Foothill Ranch and Shiloh neighborhoods, where crews can work three houses on the same block in a single month because the original roofs were installed within a year of each other.
The climate here is a double load. Windsor sits inland enough to collect 35-40 inches of winter rain that stresses valleys and underlayment, then dries out for hot summers before the Diablo winds arrive each fall, those northeast offshore gusts that hit 70+ mph and turn embers into projectiles. After the October 2019 Kincade Fire forced the evacuation of all ~27,000 residents, fire-resistant roofing stopped being a code detail and became the opening question of every sales conversation. Even homeowners outside the mapped High Fire Hazard Severity Zones now ask for Class A assemblies and hip-roof ember-blocking by default.
Our Main Windsor Services
Most calls from Windsor homeowners fall into two categories: stopping an active leak or replacing a roof that’s reached the end of its service life. Here’s how we handle each.
Roofing Company in Windsor
As a Roofing Company in Windsor, we handle everything from emergency tarping after wind damage to full re-roofs with Class A-rated assemblies. Our crews know the local permit requirements for Sonoma County’s fire hazard zones, and we coordinate with Windsor’s building department on inspection scheduling. Every visit starts with shoe covers at your door and a written price before anyone climbs the ladder.
Roof Repair in Windsor
Our Roof Repair in Windsor work focuses on the patterns this climate creates: underlayment failure behind concrete tile, valley flashing corrosion from winter rain concentration, and wind-lifted shingles after Diablo events. We stock GAF and CertainTeed repair components locally, so most repairs don’t wait on parts. You’ll get a photo of the completed work and the clean-up before we leave.
Roof Replacement in Windsor
A Roof Replacement in Windsor means navigating fire-code requirements that vary by whether your home sits inside or outside the High Fire Hazard Severity Zone boundary. We specify Atlas, Tamko, or Boral Class A assemblies where required, and we pull all permits and pass all inspections as part of the job. The 365-Day Done Right Promise covers every replacement we perform.

What Windsor Customers Say
"Roof repair after a leak. What won me over was the cleanup, they ground sheeted the flower beds so no debris fell in, and they ran a magnet over the whole yard for nails. Careful crew."
- Gordon Fiske"They repaired some lifted shingles and were so neat about it. Covered the deck, cleaned the gutters of debris when they were done, and checked the yard twice for nails. Kids play out there so that mattered."
- Lena Hargrove"Roof repair and they were meticulous about the cleanup, tarps over the garden beds and a magnet sweep for nails. We have a dog and a toddler so that mattered a lot."
- Thaddeus Bloom
