AfterRoofers in Cotati, CA
Cotati roofs take a beating from two directions: damp winter storms rolling off the coastal hills, and summer heat that bakes shingles until they get brittle. Most homes here were built between the 1960s and 1990s, so we’re usually working on composite shingle roofs that have outlived their first or second layer. The good news is that Cotati’s flat, walkable lots make roof access straightforward, which keeps estimates and jobs moving faster than in hillier parts of Sonoma County. Call us at (325) 246-5075 and we’ll give you a written price before any work starts.
Why Cotati Homes Are Different
Cotati sits low in the valley between Petaluma and Rohnert Park, which means fog rolls in most summer mornings and burns off by noon. That daily moisture cycle is rough on roofing materials, especially around nail heads and flashing where water can find a seam. We see a lot of granular loss on south-facing slopes that catch the strongest afternoon sun. It’s common to find shingles that look fine from the ground but are nearly bare on top, which shortens the roof’s remaining life without ever springing an obvious leak.
Housing stock here leans toward single-story ranchers and two-story track homes from the 1970s and 1980s, with some newer construction near the western edge of town. The original roofs on those older homes were often rated for 20 to 25 years, and many are now well past that. Flat or low-slope sections over carports and patio covers are another Cotati signature, and those need different materials and a different eye than a standard pitched roof. If a roof has both slopes and a flat section, we quote each part separately so you can see exactly what you’re paying for.
Our Main Cotati Services
Most Cotati homeowners call us for one of two things: a specific leak or damaged section that needs repair, or a full roof that has reached the end of its useful life. Each service has its own Cotati page with deeper pricing and process detail.
Roof Repair in Cotati
Cotati roof repairs usually start with a visible problem: water staining on a ceiling, missing shingles after a winter windstorm, or granules collecting in the gutters. We trace the actual source rather than patching the symptom, because water travels sideways along decking before it drips. Flashing, the metal strips that seal joints around chimneys and vents, is the most common failure point we find on Cotati homes. See how we handle repairs and what they cost on our Roof Repair in Cotati page.
Roof Replacement in Cotati
Replacement in Cotati is usually a full tear-off down to the decking, fresh underlayment, and new shingles from a manufacturer we trust. We remove the old roof rather than layering over it, because layering hides deck damage that’s already started. The written quote shows line items for materials, disposal, and labor before we touch anything. Most Cotati replacements take two to four days, weather permitting. Full details are on our Roof Replacement in Cotati page.
Roof Installation in Cotati
New construction and additions in Cotati need roofs that meet current Sonoma County building code, including the latest energy and fire-resistance standards. We coordinate with your general contractor so the roof goes on at the right point in the build and passes inspection the first time. The same written-price rule applies: you know the number before the materials arrive. Our Roof Installation in Cotati page covers the process in more detail.

FAQs About Roofers in Cotati
For minor repairs like replacing a few shingles or resealing flashing, Sonoma County generally doesn’t require a permit. Full roof replacements and new installations do require a permit and inspection. We handle the paperwork and coordinate the inspection for you.
We schedule most Cotati jobs within a few business days of your call. For active leaks during storm season, we prioritize emergency repairs. A live person answers our phones 24/7, so you’ll never wait until Monday for a callback. Call (325) 246-5075 to check current availability.
The written price covers everything we can see and reasonably expect. If we find hidden deck damage when the old roof is removed, we show you photos and a separate line-item price for that work before we proceed. You approve it first, or we don’t do it. That’s the whole point of our upfront pricing model.
