Repair & Care

Roof Repair & Maintenance

Not every roof needs replacing. We fix what is broken and keep good roofs healthy longer, so you spend on repairs, not replacements, for as long as possible.

Leaks and storm damage do not wait for business hours. We trace the leak to its source and stop flashing, shingle, and dry-rot problems before they spread into the deck.

Plan Ahead

How Long Should a Roof Last in Sonoma County?

Every roofing material ages differently, and the right choice depends on your budget, your home, and your fire exposure. Here is the typical service life we see across the North Bay.

Ranges reflect typical service life. Sonoma County's intense summer UV and wildfire exposure push the low end of every material, which is why we build Class A fire-rated assemblies and inspect for early failure.

Clay / Concrete Tile50+ yrs
Standing Seam Metal40-70 yrs
Asphalt / Composition Shingle20-30 yrs
Flat / TPO15-30 yrs

Local Knowledge

We Know Sonoma County Roofs

Santa Rosa learned in a single night what a wind-driven wildfire can do. When the Tubbs Fire swept through in October 2017, it took thousands of homes across Coffey Park, Fountaingrove, and Larkfield, and it permanently reset how this county thinks about roofs.

Your roof is the largest ember-catching surface on your home. We build Class A fire-rated assemblies that meet California Chapter 7A wildland-urban interface standards, from the underlayment up, so a rain of embers finds nothing to ignite. If you are rebuilding or hardening a home in a high fire hazard severity zone, we pull the right assembly for your Permit Sonoma or City of Santa Rosa inspection and document it for your insurer.

We also detail flashing and gutters for the roughly 30 inches of winter rain the North Bay gets between November and March, the season when hidden leaks do their real damage.

What Sonoma County Roofs Face

Wildfire & WUI Zones

Hillside and open-space parcels require Class A fire-rated roofing

30 in Winter Rainfall

Storms concentrate November to March and demand tight flashing

Intense Summer UV

Inland heat bakes shingles and shortens roof life

Aging Housing Stock

Roofs across older Santa Rosa neighborhoods are near end of life

Timing

The North Bay Roofing Calendar

Sonoma County gets almost all of its rain between November and March. The dry stretch from roughly May through October is the ideal window to replace or repair a roof, before the storms find the weak points.

Information

Santa Rosa Roofing FAQs

How much does a new roof cost in Santa Rosa?

Most residential roof replacements in Santa Rosa vary by square footage, pitch, material, and how much decking or fire-hardening the home needs. Asphalt shingle is the most affordable option, while metal and tile sit higher. We give a firm written estimate after a free on-site inspection, so you see real numbers for your roof rather than a guess.

How long should a roof last in Sonoma County?

Asphalt shingle roofs typically last 20 to 30 years, flat and TPO systems 15 to 30 years, standing seam metal 40 to 70 years, and clay or concrete tile 50 years or more. Sonoma County's intense summer UV and wildfire exposure push the low end of every material, so a local inspection is the only way to know where your roof really stands.

Do you build Class A fire-rated roofs for high fire hazard zones?

Yes. We build Class A fire-rated assemblies that meet California Chapter 7A wildland-urban interface standards, from the underlayment up. If your home sits in a high or very high fire hazard severity zone, we specify and document the correct ember-resistant assembly for your Permit Sonoma or City of Santa Rosa inspection and for your insurer.

Are you licensed and insured?

Yes. Northbay Roofing & Gutter Co. holds California contractor license number 834387 and carries full insurance. We are a GAF Master Elite contractor, a certification held by roughly the top 2 percent of roofers nationwide, which lets us offer extended manufacturer warranties.

Do you handle storm and insurance claims?

Yes. We inspect storm and wind damage, document it for your carrier, and work with your adjuster so the repair or replacement is scoped correctly. Start with a free inspection and we will tell you honestly whether you have a claim worth filing.

What areas do you serve?

We are based in Santa Rosa and serve Sonoma, Marin, Napa, Mendocino, and Lake Counties, including Windsor, Sonoma, Healdsburg, Petaluma, Rohnert Park, Sebastopol, San Rafael, Novato, Ukiah, and Cloverdale.
