What San Francisco Homeowners Say About Brennan Roofing Co San Francisco
Reviews tell you what actually happens after the estimate, after the handshake, after the crew packs up and drives off. We ask every homeowner in San Francisco to be blunt about what worked and what didn’t, because fog, salt air, and steep pitches expose weak work fast. The comments below come from customers who have seen our process up close: a written price before any work starts, background-checked technicians in uniform, and the 365-Day Done Right Promise in writing. Here’s what they told us.
Recent Reviews
“We had a leak near the chimney that two other companies couldn’t find. Brennan’s technician spent forty minutes on the roof, showed me photos of cracked flashing and failed sealant around the chimney base, and explained exactly what needed to happen. The written estimate matched the final bill to the dollar. No surprises.”

“The fog in the Sunset keeps our flat roof damp for months at a time, and I assumed that meant regular leaks were just part of living here. Brennan Roofing replaced the worn membrane and fixed the drainage slope so water actually leaves the roof now. Travis walked me through the material choices, and the price was on paper before anything started.”

Outer Sunset, San Francisco
“I called on a Saturday morning because a section of shingles had torn loose in a windstorm. A live person answered immediately, which honestly surprised me. They scheduled a repair, arrived in uniform, and replaced the damaged shingles plus the underlayment beneath them. The work is guaranteed in writing for a full year, and that meant a lot.”

“Brennan Roofing inspected our roof before we listed our house in Glen Park. Their report caught missing drip edge along one section and a few cracked tiles we hadn’t noticed. They did the repairs, handled everything through the disclosure process, and the buyer’s inspector passed the roof with zero findings.”

“We had three companies give us estimates for a full roof replacement in the Richmond. Two gave us verbal numbers and vague timelines. Brennan gave us a written line-item quote, showed us samples from GAF and CertainTeed, and scheduled the work within two weeks. The crew masked off the siding, used tarps for debris, and the final inspection passed on the first try.”

“A small leak near our skylight turned into a bigger conversation about flashing and aging sealant. Travis explained the options without pushing the most expensive fix. We went with the repair he recommended, and when I noticed a damp spot three months later, they came back at no charge under the Done Right Promise and sealed it properly. That follow-through is rare.”

Why Customers Trust Us
The pattern in these reviews isn’t an accident. It comes from rules we agreed to when we opened under the Garrison Standard, a set of operating practices established within the Garrison Partners family back in 2000. The Garrison Code means every San Francisco job starts with a written price, every technician who steps onto your roof is background-checked and in uniform, and every repair or installation is covered by the 365-Day Done Right Promise. That promise is specific: if a repair or installation fails within one full year, we come back and make it right at no charge. No exceptions, no fine print. We also stock materials from manufacturers including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so you’re choosing from real options with real differences in warranty and performance, not whatever is on a truck. When you call us, a live person answers, and the estimate you receive is the number you pay. That’s the whole deal. If you’d like us to earn a review like the ones above, call (831) 318-8819 and we’ll start with a free roof inspection and a written quote.
