AfterFast, Reliable Roofing Across San Francisco
Roofing in San Francisco is a different animal than roofing anywhere else in the Bay Area. The fog, the bay mud, the Soft-Story Ordinance, the 130-year-old Victorians leaning shoulder-to-shoulder in the Mission. A roof replacement here has to hold up to marine-layer moisture eight months out of the year, and a roof repair has to be sequenced around DBI inspection timelines that make Oakland look like the Wild West. Barrett & Sons Construction has been doing this work since 1998, and we know the difference between a Sunset District roof and a SoMa flat roof. Call (877) 610-1318 and you’ll get a live person, not a call center.
Why Barrett & Sons Construction Is San Francisco’s Preferred Roofing Company
Tom Barrett put his name on the truck in 1998, and his sons run the crews. When we say we’ll be on your roof in San Francisco, it’s a Barrett who shows up, not a subcontractor we met last week. Homeowners in the Mission District, Noe Valley, and Visitacion Valley have called us for roof work for over 25 years because we pull permits on every eligible job and we put every price change in writing before a single nail moves.
We’ve worked on Edwardians in Noe Valley with original cedar shingles, flat roofs in SoMa that sit on liquefaction-prone fill, and Victorians in the Mission where the skip sheathing rotted out from decades of fog drip. We know what the DBI inspector will flag before he walks up the driveway, and we build our scopes around it. Our reviews across San Francisco speak to that: people call us because the last contractor they hired quoted one number and showed up with another. We put the number on paper and we keep it there.
When you call (877) 610-1318, a live person answers, 24 hours a day, 7 days a week. No voicemail tag, no out-of-state call center. We schedule around San Francisco traffic and parking the way a local crew does. We carry the materials local roofs actually need: corrosion-resistant flashing, peel-and-stick underlayment, seismic clips. If your roof leaks at 6 a.m. on a Tuesday, you’ll talk to us, not a machine.

Our Roofing Services in San Francisco
Our Roofing crews handle every common San Francisco roof type, from steep Victorian gables to flat commercial-style membranes over former storefronts. Here’s how we approach the work most San Francisco homeowners call us for.
Roof Replacement & Installation
Most San Francisco homes built before 1915 have wood-frame roofs with skip sheathing: spaced boards that breathe, but also let marine-layer moisture sit against the shingle underlayment for months. We strip to the deck, inspect the framing, and install a full peel-and-stick underlayment that stops fog drip from rotting the sheathing. On Edwardian flats in the Mission and Noe Valley, we regularly reframe eaves with pressure-treated lumber because the originals have rotted through. Every replacement gets corrosion-resistant flashing, because inland-grade flashing corrodes in Salt-San Francisco air faster than most people think.
Roof Leak Repair
A roof leak in San Francisco is rarely a simple shingle replacement. On row houses, water migrates through party walls, which means the leak you see on the second floor might start three units over. We trace leaks through the deck, not just the visible stain, and we repair the flashing, underlayment, or rotted sheathing at the source. On flat-roofed buildings in SoMa and the Tenderloin, bay mud settlement opens flashing joints over time, and we reseal those seams with materials rated for movement. If the leak is active, call us at (877) 610-1318 and we’ll schedule a repair around the fog cycles, not just whatever day is open.
Metal Roofing
Standing seam metal roofs make sense in San Francisco’s climate because they shed moisture cleanly and don’t trap it the way asphalt shingles do. We install standing seam metal on both pitched and low-slope roofs, with stainless steel fasteners and flashing to handle the coastal air. A metal roof on a Mission District Victorian costs more upfront than asphalt, but in a city where fog keeps shingles damp for months, the lifespan math works in its favor. We’ll walk you through the actual cost difference on paper before you decide.
Tile Roofing
Barrel tile roofs are common on Spanish Revival homes in the Sunset and on scattered Mission Street storefronts. Tile handles San Francisco’s moisture well, but the underlayment underneath does not last forever, and broken tiles from storm debris or tree limbs let water through to the deck. We repair tile roofs by lifting and resetting tiles rather than caulking over cracks, and we replace underlayment when needed. On historic buildings with ornate cornices, we work around the decorative elements rather than through them.

Trusted Brands We Service in San Francisco
We install GAF shingle systems and underlayments because they hold up to sustained moisture better than cheaper alternatives, and we specify GAF materials on most of our San Francisco roof replacements. For shower and bath work that often accompanies roof-damage remediation, we stock Schluter and Sterling products, plus our San Francisco Cover service for added protection. We carry local parts inventory for common San Francisco roof profiles, which means we can often start repairs faster than a crew that has to order everything in.
Common Roofing Problems We See in San Francisco Homes
- Marine-layer moisture trapped under old shingles. The fog keeps underlayment damp for months, which rots skip sheathing on pre-1915 row houses from the inside out. By the time water shows through a ceiling, the deck is often gone.
- Bay mud settlement opens flashing joints. Flat-roofed storefronts and warehouses in SoMa and along the northern waterfront sit on compressible fill. When the foundation settles, roof flashing separates and leaks start.
- Wind-racked Victorian roofs spread leaks at ridges. Wood-framed Victorians without seismic clips flex in high wind, and the ridge flashing separates. The leak you see at the eaves may have started at the peak.
- Chimney flashing failures on masonry row houses. San Francisco’s dense row houses share chimney stacks, and shared stacks mean shared flashing. Repairing one side without checking the other is how leaks recur within a season.
Pricing for Roofing in San Francisco, CA
Here’s what we quote for roof work in San Francisco, based on the roofs we’ve actually scoped in the Mission, Noe Valley, the Sunset, and SoMa. These ranges reflect the two-story access, tight parking, and deck condition typical of the city’s housing stock. The exact number depends on your roof’s framing, the underlayment condition, and whether the building triggers additional DBI review under the Soft-Story Ordinance.
| Roofing Service | Typical San Francisco Price Range |
|---|---|
| Roof Replacement | $9,440 to $23,600 |
| Roof Repair | $470 to $2,125 |
| Metal Roof Installation | $17,700 to $47,200 |
What moves a roof replacement from $9,400 to $23,000 in San Francisco? The big drivers are deck condition, number of layers being stripped, access, and whether the building sits in a liquefaction zone that requires structural review. We walk every roof with you before quoting, and every number goes in writing. Call (877) 610-1318 to schedule a free estimate; we’ll send Tom’s crew out to measure, and you’ll get a line-item quote, not a phone number you can’t trace.
How San Francisco’s Fog, Bay Mud, and Soft-Story Ordinance Change a Roof Job
Here’s what separates a San Francisco roof from a roof in Walnut Creek or Livermore. The marine layer that hangs over the western half of the city from May through August keeps roof decks and underlayment damp for months at a time. A contractor who works inland can slap shingles on a dry deck and walk away. In San Francisco, the deck might still be wet two weeks after the last rain. We sequence tear-offs around fog patterns, which means we don’t strip a roof in the Outer Sunset on a day when the marine layer will sit at rooftop height until noon. We also use peel-and-stick underlayment as a standard, because it’s the only barrier that holds up to months of trapped moisture.
Then there’s the bay mud. The eastern neighborhoods covered by ZIPs like 94107 and 94103 sit on 19th-century fill and bay mud, and they liquefied badly in the 1989 Loma Prieta earthquake. Flat-roofed buildings in SoMa settle unevenly, which opens flashing joints and redirects water into parapet cracks. A roof repair on those buildings is not just a patch; it’s a flashing re-seal and a drainage check, because the leak will come back if the building settles again. Two miles west in the Sunset, the ground is anchored rock and the same roof repair is simpler.
And the Roofing in San Francisco market carries another layer: the mandatory Soft-Story Retrofit Ordinance (Chapter 4D of the SF Building Code). If your building is a pre-1978 wood-frame multi-unit building with a weak ground floor, the city likely requires a structural retrofit, and the roof work on that building runs through the same Department of Building Inspection permit pipeline. Approval timelines routinely add weeks or months to a project that would clear in days in Oakland or San Jose. We factor that into our schedule before we quote, so you’re not sitting with a torn-off roof waiting on a permit clerk.
On a 1906 Edwardian flat in the Mission, our crew stripped three layers of composition shingle to find the original skip sheathing rotted through from decades of fog drip. We reframed the eaves with pressure-treated lumber, installed a full peel-and-stick underlayment, and replaced the gutters with oversized downspouts before a DBI inspection sign-off. That job is not unusual in San Francisco; it’s what we expect on any pre-1915 roof in the fog belt.

FAQs - Roofing in San Francisco
Yes, it does, though not always directly. If your pre-1978 wood-frame building has a weak ground floor (common in tuck-under garages in the Mission and open storefronts in SoMa), the city requires a structural retrofit under Chapter 4D, and any significant roof work will run through the same DBI permit review. This means your roof project may take longer to get approved and may require structural coordination with the retrofit scope. We check your building’s status before we quote so you know the real timeline. Call (877) 610-1318 and we’ll look it up.
SoMa sits largely on liquefaction-prone bay mud and 19th-century landfill, which means foundations settle unevenly and roof structures need more careful tying to the walls. Flat roofs in SoMa also require more robust flashing and drainage than the pitched shingle roofs common in the Sunset. We also need to factor in SoMa parking, street permits, and the likelihood that the building has commercial occupants with separate access requirements. A simple Sunset roof replacement might run $10,000 to $15,000, while a SoMa flat roof with settlement issues can exceed $20,000. We also provide Driveway & Pavers - San Francisco.
Yes, it does, especially in the western and northern neighborhoods where fog sits for months. The constant moisture prevents shingle underlayment from drying out, which accelerates rot in the wood deck below. The shingles themselves can last decades, but the system underneath fails first, and that’s what shortens the roof’s real lifespan. That’s why we use peel-and-stick underlayment on almost every San Francisco roof replacement. Call us at (877) 610-1318 and we’ll explain the difference on your specific roof.
Usually yes. Roof replacement or significant roof repair requires its own DBI permit, even if a seismic retrofit is already underway on the same building. The good news is that when we handle both scopes, we coordinate the inspections so you’re not paying for multiple trips. We pull permits on every eligible job, and the permit inspector works for you, not for me. That’s why we like him on the job.
We work around them, not through them. Ornate cornices on Victorian and Edwardian row houses are often original wood, and they sit in the exact spot where roof water drains. We repair the roof membrane and flashing from behind the cornice where possible, and we replace rotted cornice wood with like-profile lumber rather than ripping it out. It’s slower work, but it keeps the building’s character intact. Tom Barrett has been doing this in the Mission and Noe Valley since 1998.
