Free roof inspection with deck photos before we talk money - GAF and Owens Corning certified installation
Fast, Reliable Roofing Company Across Sonoma
Tilehurst Roofing handles roof repair, full replacement, and maintenance across Sonoma with crews who know this valley’s specific failure points: corroded flashing in the salt-air corridor, ember-vulnerable vents in the VHFHSZ, and insurance-driven reroof deadlines. We are not a phone-in dispatch service. The people who answer your call are the same team coordinating your job, and a live person picks up 24 hours a day. That matters when a Diablo wind event has just peeled a section of ridge cap off at 2 a.m. Call (945) 303-9821 and you’ll speak to someone who can actually help, not a voicemail prompt.
Every job starts with a written price before any work begins. That’s not a perk. It’s the floor. Greg Holloway runs our Sonoma scheduling and brings his trade background to every estimate and post-job walkthrough. If a repair fails inside the guarantee period, we return at no charge under the 365-Day Done Right Promise. Written guarantee on every repair, delivered before the crew leaves the property.
Why Tilehurst Roofing Is Sonoma’s Preferred Roofing Company
Sonoma homeowners don’t call us because their roof is performing beautifully. They call because an insurer sent a non-renewal letter, or a valley leaked through the first heavy October rain, or a previous contractor’s “fix” failed within two months. We’ve built our local reputation on the jobs other roofers walk away from: steep hillside estates near Diamond A Ranch, Craftsman homes near the Plaza, 1970s ranch houses in Boyes Hot Springs with original wood shake. Each one gets a price in writing first, a crew in uniform, and a guarantee in your hands before we leave.
Our customers stay our customers because we do what we say. When we tell a Sonoma homeowner we’ll arrive in a specific window, we arrive in that window. When we say a reroof will take four days, that’s the plan we stick to unless the decking underneath tells us otherwise, and if it does, we show you photos and put the revised number in writing before any additional work proceeds. The Kingswell Way is how we’ve operated since 2000: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, come back if it fails.
We coordinate scheduling and dispatch from the brand’s San Francisco Bay Area office, but the crews who work on Sonoma roofs are local to the North Bay. They know which sections of Arnold Drive flood, which hillside properties need crane-assisted decking replacement, and which historic homes near the Plaza require consultation before any visible material change. That local knowledge is the difference between a reroof that passes inspection and one that gets flagged for WUI compliance issues on day one.
Roof Maintenance in Sonoma
Roof maintenance in Sonoma means more than cleaning gutters and eyeballing shingles. It means inspecting every fastener, valley flashing run, and drip edge section for the salt-air corrosion this corridor is known for, and documenting the condition of your ridge vents and soffit openings against ember intrusion standards. A maintenance visit on a Sonoma roof should leave you with a written report and photos, not just a handshake and an invoice.
What a Sonoma Maintenance Visit Covers
We inspect the full roof surface, but the critical work is at the edges and transitions. Drip edge that’s thinned from marine-air exposure gets replaced before it lets water wick back under the shingle edge. Valley flashing gets a close look because when it corrodes through, the leak starts at the most expensive junction on the roof. We also check every penetration: pipe boots, vent collars, chimney flashing. That’s where 80% of Sonoma leaks begin.
When to Schedule and What It Costs
Schedule maintenance in late September or early October, before the compressed rainy window opens. A typical roof maintenance visit in Sonoma runs $220-$450 depending on roof size and how many repairs the inspection turns up. If we find something that needs fixing, you get a written quote before any work proceeds. No surprises, no “while we’re up there” add-ons.
Roof Coating in Sonoma
Roof coating in Sonoma is not a substitute for structural repair, but it’s a legitimate way to extend the life of a sound flat or low-slope roof by 5-10 years. The marine air factor matters here too: standard acrylic coatings break down faster under the same salt-and-UV combination that eats regular galvanized hardware, so we specify higher-grade silicone or elastomeric systems designed for coastal-adjacent exposure.
Coating Systems We Recommend for Sonoma Exposure
For residential flat roofs and low-slope sections common on mid-century Sonoma homes, we recommend silicone coatings over acrylics. Silicone tolerates ponding water and stands up to the UV intensity we get during the long dry season. On tile roofs, we apply a tile sealant treatment that locks in granule surface and slows the spalling effect of repeated wet-dry cycling through the rainy winter.
Coating Cost in Sonoma
A flat-roof coating on a typical Sonoma home runs $3.50-$6.00 per square foot, so a 1,500-square-foot roof lands between $5,250 and $9,000. That’s a fraction of a tear-off and it buys you real years. But coating over a roof with failed decking or corroded flashing is throwing money away, so we inspect and document before we coat. If the roof needs structural work first, we’ll tell you plainly.
Trusted Brands We Service in Sonoma
We stock and install materials from seven major manufacturers so the product fits the home, not just what’s already on the truck. For Sonoma specifically, we lean on GAF for steep-slope architectural shingles with proven Class A fire ratings, CertainTeed for their Landmark series which handles the wet-dry stress of our climate well, and Owens Corning for heavy-duty underlayments that hold up during long tear-off schedules in our rainy window. Planning a reroof? We’ll walk you through material options, lead times, and which manufacturer’s warranty actually covers what in a Sonoma VHFHSZ. Call (945) 303-9821 for a written estimate.
Common Roofing Company Problems We See in Sonoma Homes
- Corroded flashing at drip edges and valleys. The salt-laden air that funnels up the Sonoma Creek corridor eats galvanized metal years faster than inland Bay Area homes. We see drip edge flaking away on homes barely 10 years into a roof’s lifespan, and valley flashing rusted through on 15-year-old roofs that should have had decades left.
- Wood shake roofs flagged by insurers. Many Sonoma homes built before the 1980s still carry original wood shake, and most of those owners are now holding non-renewal letters. The fix is a Class A reroof with ember-resistant detailing, not a patch job.
- Open ridge vents and unsealed soffits. Class A shingles alone don’t protect a home when embers can get sucked into the attic through unprotected vents during Diablo wind events. We regularly see “compliant” reroofs from other contractors that left old vent openings wide open.
- Valley leaks from improper underlayment. Sonoma’s compressed rainy season means valleys hold water for weeks at a time. If the ice-and-water shield wasn’t laid correctly or the old flashing was reused, the leak shows up in January and the homeowner is suddenly shopping for a roofer mid-storm.
Pricing for Roofing Company in Sonoma, CA
Here’s the honest range for Sonoma in 2026. Repairs: a valley reflash runs $850-$2,200, a pipe boot replacement $450-$800, a section of new shingles $650-$1,400 per 100 square feet. Full reroof: $18,000-$42,000 for a typical Sonoma home, depending on square footage, pitch, tear-off complexity, and whether we’re building back to WUI compliance (ember-resistant vents, enclosed soffits, Class A material). Tile reroofs run higher. The coastal-spec version of any job costs 8-12% more than an inland-spec because stainless fasteners, marine-grade flashing, and ember-resistant components are not optional here. Estimate is always free. The price we give you is the price you pay. Call (945) 303-9821 to schedule.

FAQs About Roofing Company in Sonoma
You need a full tear-off and reroof with Class A fire-rated material, and you likely need ember-resistant vent covers and enclosed soffits to meet your insurer’s requirements. Get it done promptly because once the policy lapses, you’re shopping for a policy you may not be able to get. We handle this exact situation weekly in Sonoma, and we’ll write the documentation your insurer needs to reinstate coverage. Call (945) 303-9821 before your policy deadline.
Because the salt-laden marine air that’s funneled up the Sonoma Creek corridor corrodes standard galvanized nails and flashing in 5-7 years, leading to shingle blow-off and valley leaks. Stainless steel doesn’t fail that way. It costs more upfront, roughly 10% more on the hardware line, but a stainless spec is what keeps your roof intact for 25+ years instead of 10.
It accelerates corrosion on metal components and degrades acrylic coatings faster than inland Bay Area locations, so we recommend silicone-based coatings and a maintenance inspection every 12-18 months instead of the inland standard of 24. The compressed rainy season also means the best maintenance window is late September, before the first heavy storms arrive. Call (945) 303-9821 to schedule.
Plan on 8-12% more for a Sonoma roof compared to an inland cities like Cotati or Petaluma. That covers stainless fasteners throughout, marine-grade drip edge and valley flashing, and ember-resistant vent covers. The inland-spec version costs less today and fails within a decade. The coastal-spec version costs a bit more and lasts as long as the shingle warranty says it will.
Yes. California’s Wildland-Urban Interface building codes require ember-resistant vents on new and reroofed homes in designated hazard zones, which includes most of Sonoma. If your ridge vents and soffit openings are not protected, embers can enter the attic during Diablo wind events and start a fire that never touches the roof surface. We install Brandguard-style covers and enclose soffits on every reroof we do here. Call (945) 303-9821 for a written estimate.
