Pricing & Cost FAQs
Most full roof replacements in San Francisco run between $14,000 and $32,000 depending on roof size, slope, material, and how much decking needs replacement. A standard 1,500-square-foot asphalt shingle roof on a single-family home in the Sunset or Richmond districts typically lands in the $16,000 to $22,000 range once tear-off, underlayment, flashing, and cleanup are included. Steep-slope Victorians in Noe Valley push higher because of access and safety rigging. We put every price in writing before work starts, so the number you sign is the number you pay. Call (831) 318-8819 for a free written estimate.
Small repairs in San Francisco usually fall between $450 and $1,800. A simple leak patch around a vent or pipe boot might be $450 to $700. Replacing a section of damaged shingles or repairing valley flashing runs $900 to $1,800. Fog-belt moisture in neighborhoods like Daly City and Pacifica accelerates flashing corrosion, so we often see repair needs there before homeowners notice visible leaks. The Garrison Standard means you get a written price before any work begins, no door-knock surprises. Call (831) 318-8819 and we'll assess what's actually needed.
Quotes vary because of material grade, disposal costs, labor rates, permit fees, and whether the contractor is pricing to code or pricing to cut corners. San Francisco's permit process adds soft costs some low bids simply omit, leaving the homeowner to sort out later. Some roofers in the Bay Area bid tear-off but exclude decking replacement, which surfaces as a surprise change order once the old roof comes off. We price the full scope up front: tear-off, decking repair, underlayment, flashing, material, and disposal. One written price, fixed before work starts. Call (831) 318-8819 for line-item clarity.
No. Estimates are free. We measure, inspect, and give you a written price for the work we recommend. You'll see the scope broken out so you can compare apples to apples. Travis Oakley, who leads our San Francisco branch, insists on this because a roof is a five-figure decision and you shouldn't have to pay just to learn what it costs. Call (831) 318-8819 and we'll schedule a time that fits your week.
No, not on the work we priced. If we uncover hidden decking rot or code-required upgrades after tear-off, we photograph the issue, show you exactly what we found, and get your written approval before any additional work proceeds. There's no automatic escalation and no vagueness. The Garrison Code includes price in writing before any work starts, and we hold ourselves to that. The goal is that you never feel ambushed. Call (831) 318-8819 if you want to talk through how fixed pricing works.
Service & Process FAQs
It starts with a free inspection and written estimate, then moves to material selection, permit filing, tear-off, decking repair, underlayment and flashing installation, material installation, and a full cleanup and inspection. Most residential replacements in San Francisco take three to seven working days from tear-off to final walkthrough, weather willing. Fog and marine-layer moisture in districts like the Outer Sunset can slow adhesive curing, so we build that into the schedule rather than rush it. Call (831) 318-8819 to start with a free estimate.
Yes. San Francisco requires permits for roof replacements and most structural roof repairs, and we pull them before work starts. The city's building department reviews plans, and inspections happen at key stages: decking, underlayment, and final. We schedule those inspections and make sure the work passes before we call the job done. A roof without a permit can complicate future home sales, insurance claims, and refinancing. Travis Oakley's team handles the paperwork so you don't have to. Call (831) 318-8819 with questions.
A typical shingle roof replacement in San Francisco takes three to seven working days. Homes with steep pitches, multiple layers of old roofing, or extensive decking damage can take longer. Weather is the wildcard. The city's fog and wind patterns rarely stop work outright, but wet decking means a delay because underlayment has to be installed on a dry surface. We give you a start window and keep you informed if the schedule shifts. Call (831) 318-8819 to discuss your specific roof and timeline.
Yes. San Francisco has thousands of Victorians, Edwardians, and mid-century homes with roof details that require real carpentry experience. Steep slopes, dormers, turrets, and original skip sheathing all need a roofer who understands the structure underneath the shingles. We inspect the framing and decking as carefully as the surface material. Older homes in neighborhoods like the Mission, Glen Park, and Bernal Heights frequently have decking that hasn't been touched since the original build, and we address that before covering it back up. Call (831) 318-8819 for an inspection.
Yes. A roof inspection tells you what you have, what's wearing, and roughly when you'll need to budget for replacement. We check shingles, flashing, valleys, vents, gutters, and the attic side of the roof deck when accessible. In San Francisco's fog-heavy corridors, inspections often catch early flashing corrosion before it becomes a ceiling stain. The inspection is free and comes with a straight assessment, not a pressure pitch. Call (831) 318-8819 and we'll take a look.
Brands & Parts FAQs
We install asphalt shingles, composition roofing, and selected standing seam and metal options suited to San Francisco's coastal climate. The materials we recommend depend on your roof slope, exposure, and budget. We work with manufacturers including GAF, CertainTeed, and Tamko because their product lines hold up to marine air better than bargain off-brands. A well-installed roof with quality underlayment and flashing will outlast a premium shingle slapped onto a weak deck. Call (831) 318-8819 and we'll walk through what fits your home.
Yes, but installation quality matters more. The big brands like GAF, CertainTeed, and Tamko all make solid architectural shingles, and the differences come down to warranty structure, color range, and regional distribution. What separates a roof that lasts 25 years from one that fails in 12 is the underlayment, flashing detail, ventilation, and decking prep beneath the shingles. We use manufacturer materials but focus most of our energy on the work you can't see from the street. Call (831) 318-8819 to discuss material options in plain terms.
Yes, in select applications. Standing seam metal performs well in San Francisco's wind and moisture, and it's a good fit for low-slope sections where shingles struggle. Metal costs more up front than asphalt, usually two to three times the material cost, but it can last 40 to 60 years with minimal maintenance. Coastal fog means we pay extra attention to fastener choice and flashing detail, because salt-tinged air accelerates corrosion in the wrong materials. Call (831) 318-8819 and we'll tell you honestly if metal makes sense for your roof.
Architectural asphalt shingles with a quality synthetic underlayment handle San Francisco's fog well, and are the most common choice for good reason. The more important defense is flashing. Marine air corrodes exposed metal flashing faster here than inland, so we spec heavier-gauge materials at valleys, chimneys, and pipe penetrations. Homes in fog-saturated districts like the Outer Richmond and Daly City benefit from extra attention at every penetration. The shingle is the shell, but the flashing is the armor. Call (831) 318-8819 for a specific recommendation.
Licensing & Insurance FAQs
Every professional working under the Brennan Roofing name is required to hold the license and insurance their state requires. We carry the coverage the job demands and can provide documentation before work begins if you want to see it. This is a non-negotiable part of The Garrison Standard. You should ask any contractor you're considering for license and insurance proof, and if they hesitate, that tells you something. Call (831) 318-8819 and we'll gladly share what we carry.
Our work is handled by professionals who work under The Garrison Code, which means they show up inside the window we gave, price in writing, work by the book, and leave the site clean. Travis Oakley runs the San Francisco branch and holds the team to that standard on every job. We don't hand your project to an unfamiliar crew and disappear. The people who start your roof are accountable for finishing it right. Call (831) 318-8819 if you want to talk through how our crews work.
We install materials from manufacturers including GAF and CertainTeed to their specifications, which means your material warranty stays intact. Beyond that, what we hold to is a set of work standards, not a plaque. The Garrison Code defines us: show up inside the window, price in writing before work starts, do it by the book, leave the site clean, and stand behind the work for a full year. Travis Oakley is the person you'll meet at estimate time, and he's accountable for every roof the San Francisco branch touches. Call (831) 318-8819 with questions.
Emergency & Response FAQs
First, contain the water inside with a bucket or tarp, move valuables away from the leak, and take photos for your insurance record. Then call us at (831) 318-8819. San Francisco's winter storms can drive rain horizontally into flashing gaps that hadn't leaked in years, and quick intervention often prevents decking rot and ceiling damage from spreading. We'll assess the source, tarp if needed to stop active water intrusion, and quote the permanent repair in writing before any work starts.
Yes. When a tree limb or storm opens your roof, we can install a temporary tarp to stop water coming in while the permanent repair is scoped and scheduled. This isn't a permanent fix, and we'll be clear about that. Tarping buys you dry time, keeps the deck from swelling, and gives you room to file an insurance claim if the damage qualifies. Our phone line is (831) 318-8819. We answer during business hours: Monday through Friday 7:00 AM to 7:00 PM, Sunday 7:00 AM to 7:00 PM, and we're closed Saturday.
In most cases, yes. We schedule repair work during our normal business hours, Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM, and most San Francisco roof repairs are completed within days of the estimate. The schedule depends on current crew load and weather, but small leaks don't get parked for weeks. Every repair starts with a written price before work starts, so you know exactly what you're approving. Call (831) 318-8819 and we'll get you on the calendar.
Yes. While our San Francisco branch is based in the city, we serve homeowners across the Bay Area, including Daly City, Berkeley, Hayward, San Leandro, Walnut Creek, Castro Valley, Novato, San Bruno, Martinez, Foster City, and Burlingame. Each microclimate is a little different. Daly City and San Bruno get heavier fog, Walnut Creek and Martinez run hotter in summer, and Berkeley's older housing stock has its own decking quirks. We price every job to the property, not the zip code. Call (831) 318-8819 to schedule.
Warranty & Guarantees FAQs
Every job we do is covered by The Garrison Standard: the work is guaranteed in writing for a full year. If it fails in that time, we come back and make it right at no charge. On top of that, the shingle manufacturers we use, including GAF and CertainTeed, offer their own material warranties that extend well beyond our labor guarantee. The difference is whether the installer stands behind the installation. We do, in writing, for a full year. Call (831) 318-8819 to talk warranty specifics.
Usually not, or only for a limited period at a prorated amount. Manufacturer warranties cover defects in the shingles themselves. What they don't cover is the more common failure point: installation errors, improper flashing, insufficient ventilation, or decking that wasn't inspected before the new roof went on. That's why our one-year written workmanship guarantee matters more in practice. We stand behind what our hands did, and the manufacturer stands behind what they made. Two different protections. Call (831) 318-8819 with warranty questions.
It's five commitments, and they're specific enough to hold us to. First, show up inside the window we gave you. Second, price in writing before any work starts. Third, do it by the book, the first time. Fourth, leave the site clean and squared away. Fifth, stand behind the work for a full year. That's the standard every Garrison company works to, and it's the reason we don't leave you wondering if the price will change or whether the crew will actually arrive. Call (831) 318-8819 and put it to the test.
