Fast, Reliable Roofing Company Across San Francisco
Most roofing work in San Francisco costs between $450 and $1,200 for a targeted repair and $14,000 to $28,000 for a full replacement on a typical Victorian or Edwardian flat-roof home. We’re Birchbark Roofing San Francisco, and we work on the city’s tightest lots, from Noe Valley to the Outer Richmond, where sidewalk staging and party-wall care decide whether a job goes smoothly. You’ll get a written price before any work starts, and a live person answers when you call (831) 228-3330, any hour.
Why Birchbark Roofing San Francisco Is San Francisco’s Preferred Roofing Company
San Francisco homeowners keep calling us because we treat a re-roof on a zero-lot-line Victorian as a neighbor problem first and a roofing problem second. Our crews know the difference between a Mission flat roof with original redwood sheathing and a Sunset District tar-and-gravel roof that’s been patched four times since 1985. That local knowledge changes how we quote, how we stage, and how we protect your home.
The Roofing Company in San Francisco work we do is covered by the 365-Day Done Right Promise: if it’s not right, we make it right. No fine print, no chasing. Erik Lindgren leads the team here, and every technician on your property is background-checked and uniformed, so the person at your door is the person we said would be there.
Since we’re part of the Cedarwell family of independently owned roofing businesses, every job also carries the Cedarwell Care Promise. That means shoe covers at the door, drop cloths through the hallway, a photo of the completed clean-up before we leave, and a written price in dollars before tear-off begins. In a city where parking a materials trailer on the wrong side of the street costs a $110 ticket, that level of forethought matters.
Styles & brands we work with
Roofing Contractor in San Francisco
A roofing contractor in San Francisco does far more than nail shingles. On this city’s housing stock, the job means navigating historic overlay review in places like the Mission and Noe Valley, coordinating party-wall notices on attached units, and often hoisting materials by hand because there’s no side yard and no alley. We handle the permit, the staging plan, and the work-hour compliance so you don’t have to learn San Francisco’s building code the hard way.
How We Stage on Tight Lots
San Francisco’s 1906-era lot coverage means many Victorians sit wall-to-wall with no side access. Our crews routinely hoist every square of roofing material from a narrow sidewalk, by hand, because there’s simply nowhere to park a boom lift. We coordinate with neighbors on shared walls before tear-off begins, file the required party-wall notice, and schedule deliveries in short windows that respect street-sweeping days and work-hour ordinances.
What a Written Price Covers
Before anyone climbs onto your roof, you’ll have a written line-item price. That number includes disposal, permits, and protection for your interior. If we discover a problem under the old roof, you’ll know what it costs to fix before we touch it. Most residential roof replacements in San Francisco run $14,000 to $28,000, and you’ll see your exact number before work starts, never after.
Roof Inspection in San Francisco
A roof inspection in San Francisco is the most affordable protection you can buy for a home in the fog belt. After a wet winter, we find flashings corroded from salt air in the Sunset and Richmond, moss holding moisture against old membranes in Glen Park, and hairline cracks in century-old redwood sheathing that only show up under seismic movement. An inspection catches these before a leak turns into a ceiling repair.
What We Look For
We walk the roof, check flashing, seams, and drainage, and photograph what we find. On flat and low-slope roofs we check the membrane for blisters and the deck for soft spots. Inside, we look at the attic for stains, venting issues, and signs of moisture the roof has been hiding. You’ll see photos of every problem we flag, not just a summary line.
When to Schedule One
Book an inspection before the rainy season, after any significant storm, or before you buy or sell a San Francisco home. Real estate transactions here often need a roof certification, and lenders want documentation. If you’re unsure when your roof was last inspected, call (831) 228-3330 and we’ll get eyes on it.
Trusted Brands We Service in San Francisco
We work with materials from GAF, CertainTeed, and Tamko, and we stock compatible parts locally so your job doesn’t stall waiting on a truck from Stockton. On San Francisco’s low-slope and flat roofs, we commonly install built-up systems with CertainTeed cap sheets and GAF underlayments, matched to what’s already on the roof when possible. If you have a specific manufacturer warranty to preserve, tell us before the quote and we’ll spec materials accordingly.

AfterCommon Roofing Problems We See in San Francisco Homes
- Fog-belt membrane rot: In the Outer Sunset and Richmond, roofs stay damp for months. Built-up membranes delaminate and blisters form where moisture gets trapped. We cut out the failed sections and install new membrane with proper drainage slope.
- Seismic cracks in redwood sheathing: Original 100-year-old redwood decking often has hairline splits from decades of tremors. Driving standard nails splits brittle boards. We use stainless fasteners and pre-drill where needed, so the structure holds.
- Party-wall disputes from tear-off: On attached Victorians, vibration from tear-off can crack a neighbor’s plaster. We file party-wall notices, photograph the shared wall before we start, and use hand tools along the property line to keep vibration down.
- Corroded flashings in coastal districts: Salt air eats galvanized flashing faster here than anywhere inland. We replace failed flashing with copper or stainless at all roof penetrations: vents, skylights, and chimneys on Presidio and Sea Cliff homes.
Pricing for Roofing Company in San Francisco, CA
Here are honest San Francisco numbers, gathered from our own jobs across the city. A targeted roof repair usually runs $450 to $1,200, depending on access and what’s failed. A full replacement on a typical flat-roof Victorian runs $14,000 to $28,000, and that range covers material grade, deck repairs, and how many stories of hoisting we have to do by hand. Metal and tile roofing on San Francisco homes starts higher because of material cost and structural loading. The thing to know is this: your written price is set before we tear off a single shingle, and it won’t change unless you approve a change. Call (831) 228-3330 for an exact quote, free.

FAQs About Roofing Company in San Francisco
Yes, in most Mission District historic overlay zones you’ll need planning review before a roof replacement, especially if the visible roofing material changes. We handle the paperwork and know what the planning department asks for. Call (831) 228-3330 and we’ll check whether your address falls in a historic district before you spend a dollar.
We file a party-wall notice with the city, photograph the shared wall before work starts, and use hand demo along the property line instead of machines. On the shared wall itself we leave the existing flashing intact until the final day, then replace it in one pass to minimize exposure and vibration. Call (831) 228-3330 if you have a Noe Valley job coming up, and we’ll walk you through the exact sequence.
The most common reason is rotted or cracked decking hidden under the old membrane. In the Richmond’s fog belt, deck boards that looked fine from above turn out to be soft once we open the roof. A second common cause is discovering the old torch-down was installed over multiple failed layers that all need to come off before code-compliant re-roofing. We give you photos and a written cost for any additional work before we proceed, and you approve it first.
Usually yes. We stage materials in the smallest footprint possible and keep a pedestrian path open when the sidewalk width allows. If we must close a section for safety, we apply for a permit and post the required notice. We’ll tell you exactly what’s needed before the quote is set, not after.
Yes. The building inspector must see the underlayment before we install the finish surface, and again at completion. We schedule those inspections and stay on site for them, so the job doesn’t idle waiting for the city. If a correction is issued, we fix it and get re-inspected, and the 365-Day Done Right Promise covers the work.
