Roofers in San Francisco, CA
Roofing in San Francisco costs more than the national average because the work happens on steep, ornate homes that are often over a century old, on lots where ladders barely fit between buildings. Most roofs here are two- to four-story wood-framed Victorians and Edwardians built between 1880 and 1920, many in rows with shared walls and minimal setbacks. Wind-driven rain, salt air, and a fog layer that keeps roofs damp for months shape every repair and replacement we do. Call (831) 318-8819 to get a written price before any work starts.
Why San Francisco Homes Are Different
San Francisco’s dense rows of Victorians and Edwardians sit in a marine climate where fog rolls in off the Pacific and keeps north- and west-facing slopes damp long after the rain stops. That persistent moisture promotes moss and algae on shingles, especially in the Sunset and Richmond districts, where we often find cedar shingles rotted along the bottom edge while the upper roof still looks sound. The homes themselves present a second challenge: steep pitches, ornate trim, multiple roof penetrations like chimneys and skylights, and original wood-shingle or composition-shingle roofs that have weathered a hundred winters.
Access is the third factor. Narrow lots and shared walls mean scaffolding and ladder placement have to be planned carefully, and in historic districts, the city’s planning rules often limit what materials you are allowed to use on the visible elevations. That’s not a problem for us, because our crews work to written specifications and we pull the permits and handle the paperwork. But it does mean the job takes a disciplined approach, not a one-size-fits-all bid.
Styles & brands we work with
Our Main San Francisco Services
San Francisco homeowners call us most often for two things: full roof replacement on older homes that have reached the end of their service life, and targeted repair work to stop leaks before they spread under the decking.
Roofing Company in San Francisco
Full roof installation and replacement in San Francisco means working on steep slopes with limited access, often in historic districts where materials are specified by the city. We remove the old layers down to the decking, inspect the framing for rot, install new underlayment and drip edge, and lay the shingle or tile system you choose from lines including GAF, CertainTeed, and Owens Corning. Every replacement includes a written price before any work starts, and the full job is covered by our 365-Day Done Right Promise. Roofing Company in San Francisco
Roof Repair in San Francisco
Most San Francisco roof repairs start with moisture intrusion at a penetration: a chimney, a skylight, a vent pipe, or a section of flashing that has pulled away from the wall. In the Sunset and Richmond, we also see a lot of rot along the bottom edge of cedar shingles where fog hangs longest. We find the source, replace the failed material, and put the fix in writing for one full year. If it fails within that year, we come back at no charge. Roof Repair in San Francisco
Roof Inspection in San Francisco
A roof inspection in San Francisco is the most direct way to find out what you have before it becomes an emergency. We walk the roof, check the flashing, decking, underlayment, and drip edge, and document what we find in photos and a written summary. For older Victorians and Edwardians, we pay close attention to the areas around chimneys and skylights and to any slope that faces the fog. You get a straight answer about remaining lifespan and what needs attention now versus what can wait. Roof Inspection in San Francisco

What pushes price up in San Francisco is access: a three-story Victorian with a steep 12/12 pitch and no side lot for a ladder costs more to work on than a single-story in the flats with easy reach from every side. Historical district requirements can also narrow material choices and add permit steps. Whatever the number ends up being, you will have it in writing before any work begins, and that price does not move at the door.
