Fast, Reliable Roofing Company Across Berkeley
Finding a roofing company in Berkeley that shows up on time, puts the price in writing before work begins, and stands behind the job for a full year is harder than it should be. We’re Brennan Roofing Co San Francisco, and we work across Berkeley every week, from the flats near San Pablo Avenue to the winding streets of the Berkeley Hills. Our crews know what a 1920s craftsman roof needs, what the city’s hillside fire code demands, and how eucalyptus debris clogs a gutter faster than you’d think. When you call (831) 318-8819, a live person answers, and your free estimate comes with a written price. That’s the whole point.
Why Brennan Roofing Co San Francisco Is Berkeley’s Preferred Roofing Company Company
Berkeley homeowners call us because we show up inside the promised window, in uniform, with a background-checked crew. The Roofing Company team that arrives at your door is the same crew doing the work. No subcontractor roulette, no guy in a pickup who might or might not come back. Every job begins with a written price. That number does not move at the door, not for hidden rot, not for a surprise repair, not for anything. We put it in writing before we order materials, and the Garrison Standard says that number is the number.
We’re part of the Garrison Partners family, founded in 2000, and each location is independently owned and operated to that same standard. Travis Oakley leads our crew, and he holds every technician to the Garrison Code: document what you find, write the price down, do the work right, and come back free if it fails within a year.

Roof Coating in Berkeley
Roof Coating in Berkeley is a cost-effective way to extend the life of a low-slope or flat roof without a full tear-off. Most flat and low-slope roofs in Berkeley are on mid-century apartment buildings, garage roofs, and some hillside homes with parapet walls. A roof coating here runs $2.50 to $6.00 per square foot depending on the coating system and how much prep the existing surface needs. On a 1,500-square-foot flat roof, expect to pay between $3,750 and $9,000.
Berkeley’s wet winters and foggy mornings mean a flat roof takes a beating. Standing water, moss on the low points, and UV breakdown from dry summers all cut into the membrane. A silicone or acrylic coating seals the surface, reflects heat, and buys years before replacement. The catch is prep: if the existing roof has blisters, cracking, or old patching, we scrape and prime before coating. Skipping that step is why some coatings peel within a year.
Coating as an Alternative to Replacement
On a Berkeley flat roof with no structural issues, coating makes sense when the membrane is sound but aging. A replacement runs $12 to $18 per square foot. Coating costs a quarter of that. We won’t coat a roof that’s too far gone, because a coating over failed decking is money wasted.
What a Coating Won’t Fix
A roof coating is not a repair for missing flashing, rotted decking, or poor drainage. Those issues need corrections before coating, or the coating fails at the same weak points. We walk the roof, document what we find, and write the prep work into the price. No surprises later.
Free Roof Estimate in Berkeley
A Free Roof Estimate in Berkeley from our team includes an inspection of your current roof, a written breakdown of materials and labor, and a clear explanation of what the job requires. We schedule estimates across Berkeley every weekday, and we call when we’re 30 minutes out. The estimate is free, and the price you get is the price you pay if you hire us.
We don’t do phone-sight quotes. We need to walk the roof, check the attic, and look at the flashing before we give you a number. A 1930s bungalow off College Avenue might hide rotted built-in gutters under the eaves. A 1960s rancher in the Berkeley Hills might need seismic strapping added before re-decking. We find these things during the estimate, not after tear-off.
What the Written Quote Includes
Your quote lists the roofing material, underlayment, flashing, drip edge, decking repairs, debris removal, permits, and labor. It includes the 365-Day Done Right Promise in writing. If a repair or installation fails within one full year, we come back free. Not a pro-rated credit. A return visit at no charge.
How Long an Estimate Takes
Plan on 45 minutes to an hour for a standard single-family home. A hillside property with multiple slopes and dormers might take 90 minutes. We send the written quote by email the same day, and we’ll sit down and walk through line items if you want. No pressure, no follow-up calls every day for a month.
Trusted Brands We Service in Berkeley
We install roofing from Owens Corning, IKO, and CertainTeed, among others, because these manufacturers stand behind their materials with real warranties the same way we stand behind our labor with the 365-Day Done Right Promise. Berkeley homeowners get the full product line explained plainly. We’ll show you the difference between an architectural shingle and a Class A standing seam metal panel in terms of cost, lifespan, and fire rating. We stock common flashings, underlayments, and ridge vents locally for Berkeley jobs, which means we don’t lose a week waiting on a truck from Sacramento when your roof is torn off and the rain is coming.
Common Roofing Company Problems We See in Berkeley Homes
- Skip sheathing on pre-1940 roofs. Berkeley’s craftsman and shingle homes were often built with spaced boards, not solid decking. Modern shingle warranties require solid plywood or OSB underneath, so the old sheathing has to be overlaid before installation. If a roofer quotes you without walking the attic, they’re either planning a change order or planning to install over a surface that won’t hold.
- WUI fire code violations. Berkeley Hills homes in Wildland-Urban Interface zones need Class A rated materials and enclosed eaves. Standard architectural shingles sometimes don’t qualify. A roofer unfamiliar with Berkeley’s hillside code will install a roof that fails inspection. We pull permits, we build to the code, and we pass inspection the first time.
- Moss and eucalyptus debris. Berkeley’s fog, shade, and eucalyptus canopy create ideal moss conditions on north-facing slopes. Debris accumulates in valleys and behind chimneys, trapping moisture against the shingles and flashing. Regular gutter cleaning helps, but the real fix is proper ventilation and installing moss-resistant materials where appropriate.
- Hidden rot under built-in gutters. Older Berkeley bungalows often have recessed gutters built into the eave. When the gutter leaks, water soaks the fascia and rafter tails for years before the homeowner notices. Tear-off is the only way to see this damage. We document it, show you photos, and the written price includes the repair.

AfterPricing for Roofing Company in Berkeley, CA
A full roof replacement on a standard Berkeley home runs $14,000 to $28,000 depending on square footage, pitch, material, and decking condition. Roof repair jobs in Berkeley typically fall between $450 and $1,800. Roof inspections, including the written report, cost $250 to $500 and that fee is credited toward any work you hire us to do. Hillside homes with multiple dormers, steep slopes, and WUI material requirements land at the higher end. A standing seam metal roof on a Berkeley Hills home can run $28 to $42 per square foot because of the fire-rated materials, custom flashing, and fall protection the job requires. A coating on a flat garage roof is the cheapest option, usually $3,750 to $9,000 total.

FAQs About Roofing Company in Berkeley
Yes, in most cases. Berkeley’s Wildland-Urban Interface map includes large portions of the hills, not just parcels touching Tilden Park or Claremont Canyon. If your roof is within the WUI zone, the city requires a Class A assembly, which usually means standing seam metal, treated wood shake, or specific Class A rated composite shingles. The only way to know for sure is to check your property against the city’s current map and pull the correct permit. We confirm this during the estimate so you’re not surprised at inspection. Call (831) 318-8819 and we’ll verify your property’s designation before quoting materials.
We overlay it with plywood or OSB decking before the new roof goes on. Skip sheathing was standard in Berkeley before 1940, and modern shingle manufacturers won’t warranty a roof installed over spaced boards. The overlay adds to the cost and the labor, but it’s not optional if you want the shingle warranty and a roof that meets current code. We inspect the attic during the estimate, photograph the existing sheathing, and write the decking money into your quote. If the original boards are rotted or split, we replace those sections at the same written price unless the damage extends into the rafters, in which case we show you photos and agree on the change before we proceed.
Sometimes, but not always. Standard architectural shingles are typically Class A rated only when installed with a specific underlayment. In Berkeley’s WUI zones, the roof assembly has to meet the city’s stricter requirements, and the shingle product must be approved for that use. CertainTeed and Owens Corning both make Class A rated architectural shingle lines, but the underlayment and ventilation details matter as much as the shingle itself. We’ll tell you exactly which products pass Berkeley’s hillside inspection before you pay for anything. Call (831) 318-8819 and we’ll bring samples to your estimate.
We inspect the attic and the roof surface during the estimate, then we write the known conditions into the price. For the unknowns under the old roof, we include a clearly labeled contingency line in the written quote that covers decking replacement and flashing repairs. That contingency is documented, priced per sheet or per linear foot, and only charged if we actually use it. You’ll see every line item before any work starts. No change orders appear at the door after tear-off. Travis Oakley reviews every Berkeley quote personally before it goes out.
Shade, fog, and leaf debris are the drivers. Eucalyptus and redwood trees shed year-round, and the debris sits in gutters and valleys, holding moisture against the roof. On Berkeley’s north-facing slopes, that moisture feeds moss. The fix is a combination of gutter guards, proper attic ventilation, and installing moss-resistant shingles where the exposure calls for it. We can also shape trees away from the roof line if a branch is the main source. During your free estimate we’ll show you where the debris is collecting and what it would cost to stop it. Call (831) 318-8819.
