AfterRoofers in San Francisco, CA
Roofing work in San Francisco demands a different playbook than anywhere else in California. The city’s flat and low-slope Victorian and Edwardian rowhouses face a moisture threat that has nothing to do with rain, and everything to do with the fog that rolls in off the Pacific and sits on these roofs for weeks at a stretch. We dispatch crews from our San Francisco Bay Area office to handle everything from emergency leak tracing in the Mission to full membrane replacements in the Outer Sunset. Call us at (945) 303-9821 and a live person will pick up, day or night.
Why San Francisco Homes Are Different
The bulk of San Francisco’s housing stock is attached Victorian and Edwardian wood-frame rowhouses, most rebuilt after 1906, with flat or nearly flat roofs originally covered in built-up tar-and-gravel. In the Outer Sunset and Outer Richmond, the 1930s and 1940s stucco “Sunset-style” homes repeat the same flat-roof pattern. That concentration of low-slope roofing is unusual nationally, and it shapes everything about how we work here.
The real enemy is Karl the Fog. On 100-plus days each year, that marine layer condenses directly onto roof membranes, saturating seams and parapet flashings even when no rain falls. Salt air off the Pacific and the Bay corrodes metal flashings and fasteners faster than in inland cities like San Jose or Walnut Creek. On attached rowhouses in the Mission, Castro, and Noe Valley, parapet walls are shared party walls, so re-flashing work often requires neighbor coordination. The SF Department of Building Inspection also requires permits for full roof replacements; skipping it is common, but an unpermitted roof surfaces in escrow inspections and kills deals in one of the country’s most litigious real-estate markets.
Our Main San Francisco Services
San Francisco homeowners call us most often for these three jobs. Each has its own page with detailed pricing, local conditions, and what to expect.
Roofing Company in San Francisco
Our Roofing Company in San Francisco handles inspections, maintenance programs, and leak diagnostics on the flat and low-slope systems that dominate the city. We carry modified bitumen, torch-down, and TPO membranes suited to fog-heavy microclimates, and we stock flashing, fasteners, and sealants rated for salt-air exposure. Every visit starts with a written, line-item price before any work begins.
Roof Repair in San Francisco
Our Roof Repair in San Francisco crew traces leaks that other roofers miss because they look for rain damage instead of fog-driven moisture intrusion. We repair membrane seams, replace corroded flashings, clear drains causing chronic ponding, and re-seal parapet walls. Every repair carries a written guarantee; if it fails, we return at no charge under our 365-Day Done Right Promise.
Roof Replacement in San Francisco
Our Roof Replacement in San Francisco service pulls the required DBI permits, coordinates with adjacent owners on shared parapets, and installs systems from GAF, CertainTeed, Owens Corning, and IKO selected for your specific block’s exposure. We document every layer removed and installed, so your roof passes escrow inspection without surprises.

FAQs About Roofers in San Francisco
Yes. The San Francisco Department of Building Inspection requires a permit for full roof replacements, and we handle the application, inspection scheduling, and sign-off as part of every job. An unpermitted roof surfaces during escrow and can derail a sale. Call (945) 303-9821 to schedule your free estimate.
We answer calls with a live person 24 hours a day, and we schedule leak diagnostics as soon as our crew availability allows. Fog-driven leaks often worsen faster than rain leaks because the moisture source is constant, so we prioritize active intrusion calls. Call (945) 303-9821 to get on the schedule.
No. On attached rowhouses, parapet walls are party walls, and proper re-flashing requires access to both sides. We coordinate with adjacent owners before work begins and document the agreement in writing. If your neighbor is uncooperative, we can discuss interim waterproofing options. Call (945) 303-9821 to talk through your specific situation.

What San Francisco Customers Say
"Had a leak over the kitchen every time it rained hard. Two other roofers wanted to replace the whole roof. Tilehurst found the bad flashing, fixed it, and it's been dry through three storms since. Honest people."
- Gary Whitfield"The estimator climbed up, took photos, and showed me the actual problem areas instead of just talking. No pressure to replace anything that didn't need it. Repair's held up great."
- Tom Easley"Gutters and a section of shingles after a big wind. Answered the phone right away, came when they said, and the price on the quote is what I paid. Easy to deal with."
