Roofing Company in Sonoma - Written Price, Workmanship Warranty

Fast, Reliable Roofing Company Across Sonoma

Roofing work in Sonoma is rarely a simple tear-off. The houses here carry real history, and the city’s design review office and wildfire codes both have a say in what goes back on your roof. That’s why a Roof Inspection in Sonoma should come first, so the company knows the local rules before the first shingle comes off.

Call (361) 320-9467

Brennan Roofing serves Sonoma with written pricing before any work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise in writing on every job. We answer by a live person around the clock. Call us at (361) 320-9467 to schedule a free estimate.

Key takeaways for Sonoma homeowners:

• Downtown historic-overlay homes often cannot switch materials without city approval.
• Wildfire code requires ember-resistant detailing even when the roof material is approved.
• Hidden decking rot on older homes is common. We price it before we open the roof.
• Every job starts with a written price. No work begins until you have that number on paper.

Why Brennan Roofing Is Sonoma’s Preferred Roofing Company

Sonoma homeowners have called us for years because we do not change our price at the door. The number we write down before the tear-off is the number that stands when the job is done. That matters in a town where the city can reject a permit application mid-project and send the whole job sideways. Our Sonoma customers know we account for design review and wildfire code before we quote, not after.

The Roofing Company team at Brennan operates under what we call the Garrison Standard: written price before any work starts, uniformed and background-checked technicians inside the promised window, and a one-year written guarantee on every repair and installation. If something fails within that year, we come back at no charge. That’s not a slogan. It’s in the contract.

Travis Oakley leads our crew, and the work is backed by the full weight of the Garrison Partners family, founded in 2000. Each location is independently owned and operated, but the standard is the same on every roof we set foot on. Phones are answered by a live person 24/7. No voicemail, no callback queue.

Metal Roof Installation in Sonoma

Metal roof installation in Sonoma runs $1,350 to $2,100 per square for standing-seam systems, with most homes landing between $18,000 and $42,000 total depending on roof size, pitch, and the condition of the decking underneath. Metal is the smartest choice for Sonoma’s wildland-urban interface because it carries a Class A fire rating and sheds embers without igniting.

We install standing-seam and metal tile profiles from manufacturer lines including GAF and Owens Corning, with ember-resistant venting and fire-resistive underlayment spec’d for Sonoma’s Diablo wind season. On hillside properties east of Broadway where wind exposure runs high, metal often outlasts every other material by two decades.

Standing-Seam for Hillside Exposure

Homes in the hills above Sonoma, off Arnold Drive and Lovall Valley Road, catch the full force of fall Diablo winds. Standing-seam panels lock together with concealed fasteners, which means no exposed screws to back out in 60 mph gusts. We detail the ridge, eaves, and valleys with ember guards rated for wildland interface zones.

Historic-Overlay Metal Tile Match

Few people realize the City of Sonoma will accept metal tiles that replicate the profile of original clay or Spanish tile on historic-overlay homes. This satisfies both the preservation board and the wildfire code, and it drops the roof weight significantly compared to concrete or clay. We handle the design-review paperwork and supply the documentation the city needs to approve the match.

Residential Roofing in Sonoma

Residential roofing in Sonoma splits into two very different jobs: the 1890s Victorians and Spanish Colonials near the Plaza, and the 1960s-70s ranch homes and recent custom builds stretching out toward Boyes Hot Springs and the Mayacamas foothills. The older stock almost always has skip sheathing, which is code for gaps between the boards, and that changes how we price and how we underlay the roof.

A standard asphalt shingle roof on a Sonoma ranch home runs $680 to $1,050 per square, so a 20-square roof lands between $13,600 and $21,000. Tile and clay run higher, typically $19 to $32 per square foot installed. Wood shake replacements in the historic overlay are the most expensive, often $28 to $45 per square foot, because the material must match and the underlayment must carry a Class A rating.

Working Within the Historic Overlay

If you live on or near Sonoma Plaza, on streets like Spain Street, East Napa Street, or First Street East, your roof is subject to design review. You may not swap clay tile for architectural shingles without a fight you’re likely to lose. We know the process, we prepare the application, and we quote the roof that will actually get approved, not the roof that’s cheapest to install.

Wildfire Detailing on Every Roof

Every residential roof we install in Sonoma gets ember-resistant vents, closed soffits where needed, and fire-resistive underlayment at the eaves. The county’s wildland-urban interface inspection is not optional, and insurance companies are dropping policies over roofs that fail it. We build to the code the first time so there’s no reinspection, no delay, and no lapse in coverage.

Trusted Brands We Service in Sonoma

Brennan Roofing installs materials from GAF, CertainTeed, and Owens Corning, chosen for how they hold up under Sonoma’s hot summers and wet winters. We keep common profiles and colors stocked regionally, so a Sonoma homeowner waiting on a replacement panel is not stuck for three weeks. GAF Timberline HDZ shingles, CertainTeed Grand Manor, and Owens Corning Duration series are all options we quote side by side with plain-English explanations of what each does and what each costs.

Common Roofing Company Problems We See in Sonoma Homes

• Rotted skip sheathing on pre-1940 homes. The original boards under those clay tiles were never meant to hold up to a century of rain. We find dry rot in at least a third of the older roofs we open in the Plaza district, and we price the decking replacement before the tear-off starts.
• Failed flashing at chimneys and valleys. Sonoma’s wet winters push water through any gap in the flashing. Homes with original masonry chimneys on the east side of town see this constantly, and the fix is full flashing replacement, not caulk.
• Unpermitted asphalt shingle replacements. A contractor who ignores the historic overlay puts a Sonoma homeowner in a bad spot: the city can flag the property, insurance can deny a claim, and the roof may have to come off again. We fix these the right way, with the city in the loop from day one.
• Ember intrusion at vents and eaves. During Diablo wind events, embers travel a mile or more ahead of the fire front. Open gable vents and unsealed eave gaps are the most common entry points we see on hillside homes near the Mayacamas.
