Roofers in San Francisco, CA
Roofers in San Francisco work on a housing stock unlike almost anywhere else in the country: century-old Victorians and Edwardians with flat or low-slope roofs, set in dense rows where your neighbor’s wall is sometimes six feet from yours. That changes how we stage a site, how we handle historic details, and how we protect your home during tear-off. If you’re looking for a roofing company in San Francisco that puts the written price and the clean-up promise ahead of a handshake, call Birchbark Roofing at (831) 228-3330. We’ll walk you through what your roof actually needs.
Why San Francisco Homes Are Different
Most of San Francisco’s residential roofs sit on late 19th and early 20th century wood-frame Victorians and Edwardians. These homes were often finished with tar and gravel or asphalt, and many have since been switched to modern membranes like TPO, PVC, or modified bitumen. Flat and low-slope work is the default here, not the exception, and that requires a roofer who spends real time on detailing, drainage, and laps around venting and parapet walls.
The climate adds another layer. Cool, foggy summers and wet winters mean moss and algae show up on older materials, and the salt air near the Sunset, Richmond, and other coastal districts corrodes metal flashings faster than homeowners expect. At the same time, San Francisco’s lack of freeze-thaw cycles takes one kind of stress off the roof, which is why some original systems here outlast similar installs in colder climates. In neighborhoods like the Mission or Noe Valley, it’s common to find original redwood sheathing that has survived a hundred years but turned brittle. When we reroof, we fasten carefully to avoid splitting that old wood, especially with the seismic movement this city experiences. Many jobs in historic districts also need design review or specific material approvals, and we plan for that on day one.
Styles & brands we work with
Our Main San Francisco Services
Most San Francisco homeowners reach out to us for one of two reasons: an active leak or damage, or an older roof that has lived its useful life and needs to come off. Below are the three ways we help.
Roofing Company in San Francisco
As a full-service Roofing Company in San Francisco, we handle everything from small leak investigations to full-system maintenance on flat and low-slope roofs. That often means checking parapet wall flashing, clearing clogged drains or scuppers, and evaluating membrane seams that the fog and salt air have been working on. We bring a written price in dollars before any work starts, and our crews arrive background-checked and in uniform, with shoe covers and drop cloths in hand. This page gives you the city-level overview; that page covers the whole scope of general roofing we do here.
Roof Repair in San Francisco
Roof Repair in San Francisco usually starts with finding where water is actually getting in, which on a flat roof can be ten or fifteen feet from the visible stain on your ceiling. We trace the leak, open only what we need to, and give you a written price before repair work begins. On older homes, we’re careful around brittle redwood sheathing and flashings that may have been patched before. Most repair jobs here involve a membrane patch, flashing work, or drain clearing. The repair page has pricing and the repair process in detail.
Roof Replacement in San Francisco
When a roof has reached the end of its service life, Roof Replacement in San Francisco means tear-off to the deck, inspection of the framing and sheathing, and installation of a new system suited to your slope and your historic district rules, if they apply. On flat roofs, we typically recommend modern single-ply or modified bitumen systems; on low slopes, composition shingles from brands we trust. Every replacement carries our 365-Day Done Right Promise, and the clean-up photo comes before our crew leaves your property. Patterns from the page on roof replacement: pricing, materials, and the timeline are all there.

AfterPricing for Roofers in San Francisco, CA
Most roofing work in San Francisco falls within predictable ranges, and you should know those numbers before any company starts work. Below are the figures we use for straightforward residential work in the city:
| Service | Typical range in San Francisco |
|---|---|
| Roof leak investigation | $275 – $450 |
| Small membrane patch (flat/low-slope) | $650 – $1,200 |
| Flashing repair or replacement | $700 – $1,800 |
| Drain or scupper clearing and resealing | $400 – $800 |
| Flat roof replacement (TPO/PVC/modified) | $12,000 – $28,000 |
| Low-slope shingle replacement | $14,000 – $32,000 |
| Underlayment and coating refresh | $5,000 – $12,000 |
Prices in San Francisco push upward when access is tight, when a rooftop is four stories up with minimal staging space, or when historic district rules require specific materials and review time. Sea-air corrosion on flashings can also extend the replace-versus-repair scope. Whatever the number is, you’ll have it in writing before any work starts – that’s how we do every job.
Neighborhoods We Serve in San Francisco

Yes. Many Victorians and Edwardians fall under historic district or landmark rules that restrict material types and visible roof features.
