Fast, Reliable Roofing Company Across Foster City
A roof replacement in Foster City typically runs $18,000 to $42,000 for a standard single-family home, and roof repairs usually land between $450 and $1,800. Most jobs take one to three days once materials are on-site, though HOA architectural review can add two to six weeks to the front end. We know that calendar because we file the submittals ourselves. Call (831) 318-8819 and we’ll walk the roof with you, write the price down, and get the packet moving – in that order.
What makes Foster City different from every city around it isn’t the size of the homes. It’s the combination of salt air off the lagoons, strict wind-uplift code, and an HOA review process that decides what goes on your roof before we ever lift a shingle. The Roofing Company crew we send here has torn off enough Foster City roofs to know what that means. We don’t schedule tear-off until the architectural committee signs off, and we don’t file a submittal with missing wind-uplift test reports that get it kicked back. That’s the kind of thing you learn by working here, not by reading a brochure.
Why Brennan Roofing Co San Francisco Is Foster City’s Preferred Roofing Company Company
Homeowners in Foster City call us because the price goes on paper before any work starts, and because the crew that shows up is background-checked, uniformed, and knows the difference between a Harbor Cove tract home and a lagoon-front custom. Travis Oakley runs our operation under The Garrison Standard – the same discipline on every job, no matter the size. A roofer who shows up late to an estimate will show up late to the tear-off. We don’t.
Our Foster City customers tell us the same thing repeatedly: they had another roofer quote the job, then the number moved when the crew arrived. That doesn’t happen with us. The written price you approve is the price you pay, full stop. And every job carries the 365-Day Done Right Promise – in writing, for one full year, with a free return visit if anything fails. Phones are answered by a live person around the clock. Not a callback queue.
Styles & brands we work with
Roofing Contractor in Foster City
A roofing contractor in Foster City does more than nail shingles – we handle the submittal, the tear-off, the marine-grade fasteners, the wind-uplift details, and the final inspection. On a typical home here, that means working through the HOA’s architectural review committee before the first truck rolls, then executing a roof that holds up to salt-laden winds off the Bay. Plan on $18,000 to $42,000 for a full replacement, depending on squares, pitch, and what’s hiding under the old shingles.
Decking, Drip Edge, and What Holds Up
Foster City’s salt air chews through standard galvanized drip edge within five years. We spec marine-grade aluminum drip edge and coated fasteners on every job, not just lagoon-side homes. When we strip a roof, we inspect the decking before we lay anything new. If the sheathing is spongy from decades of fog condensation, we cut it out and replace it rather than nailing into rot and calling it done.
Cathedral Ceilings and Low-Slope Sections
Lots of Foster City homes built in the 1960s and 1970s have cathedral ceilings with no attic ventilation. That changes how we spec underlayment and how we handle tear-off, because there’s nowhere for moisture to escape. On low-slope built-up sections, we use materials rated for that pitch. Not every shingle can go on a 2:12 slope, and we won’t install one that’s not rated for it.
Commercial Roofing in Foster City
Commercial roofing in Foster City means flat and low-slope built-up systems on offices, retail centers, and HOA-managed townhouse complexes, where the warranty matters as much as the installation. These jobs run anywhere from $12 to $28 per square foot depending on system type – TPO, modified bitumen, or coated metal. Foster City’s planning requirements for commercial buildings often trigger energy-efficiency documentation, and we handle that paperwork as part of the bid.
TPO and Modified Bitumen Systems
For most commercial buildings here, TPO is the practical choice – it reflects heat, welds into a continuous membrane, and holds up to pooling water during winter storms. Modified bitumen, on the other hand, is what we recommend for older buildings with a lot of foot traffic from HVAC maintenance or where the deck has more flex. We’ll give you a straight comparison with numbers for both, so you’re choosing with information rather than guessing.
Wind-Uplift Compliance
The Bay side of Foster City gets hit with gusts that test every roof edge. Commercial systems here need wind-uplift ratings that meet current code, and the only way to prove that is with the manufacturer’s test report filed alongside the permit. We pull that report before we submit, so the permit isn’t sitting on someone’s desk while your old roof keeps leaking.
Trusted Brands We Service in Foster City
We install materials from Owens Corning, IKO, and Atlas on Foster City homes, and we keep local stock on the profiles these neighborhoods use most. That means when the architectural review approves a specific shingle color, we’re not waiting two weeks on a special order from out of state. Travis Oakley picks materials based on what actually performs in this microclimate – high wind ratings, algae-resistant granules for the fog-side slopes, and colors that match what each Foster City neighborhood has already approved. You’ll see the options laid out plainly, with the trade-offs explained in plain English, before you commit to anything.

AfterCommon Roofing Company Problems We See in Foster City Homes
- Rusted drip edge and popped nails at lagoon-side eaves. The salt air and morning fog work on fasteners constantly. Within five years, standard drip edge rusts through and shingles start lifting. We replace with marine-grade aluminum and coated fasteners on every edge, not just the water-facing ones.
- Spongy decking from fog condensation wicking up under the eave. On north-facing slopes and anywhere fog lingers, condensation gets into the decking and rots it from the underside. We extend ice and water shield full-length along those eaves – not just the first three feet – because that’s where Foster City roofs actually fail.
- HOA submittal packets kicked back for missing documentation. The architectural review committees here are specific about what they want: contractor license number, manufacturer wind-uplift test report, shingle sample, and a color photo of the existing roof. Miss one item and you lose two weeks. We file complete packets the first time.
- Skip sheathing on cathedral-ceiling homes that can’t hold modern fasteners. A lot of these 1970s homes were built with spaced boards, not solid plywood. You don’t know until the old roof comes off. We pre-inspect before tear-off, so the calendar and the price reflect what we’ll actually find.

FAQs About Roofing Company in Foster City
Yes, for nearly every home in Foster City’s planned subdivisions, the HOA architectural review committee must approve your roof before tear-off begins. We file the submittal for you – including the license number, the manufacturer’s wind-uplift test report, shingle samples, and photos – so the packet is complete on day one. A complete packet usually gets through review in two to four weeks. Call (831) 318-8819 and we’ll check your specific HOA’s requirements before you spend anything.
Because ice and water shield is really a waterproof membrane, and in Foster City it’s fog condensation, not ice, that rots your decking. The marine layer wicks moisture up under the drip edge and into the eave sheathing every morning. We extend that membrane full-length along lagoon-side and north-facing eaves – past the standard three feet – so condensation can’t reach the wood. It’s cheap insurance against a decking replacement that costs thousands.
In most cases, yes. We’ve installed composite and architectural shingles styled to read as wood shake on homes where the HOA has moved away from real wood due to fire code. The key is getting the shingle sample and manufacturer profile approved by the architectural committee before ordering material. We handle that submittal, and we’re familiar with what Foster City HOAs typically approve for shake-look replacements. Call (831) 318-8819 and we’ll review your community’s design guidelines with you.
We pre-inspect the attic and the decking before we tear anything off. Cathedral ceilings mean no attic ventilation, so we spec underlayment and venting details that work for that assembly, and on low-slope built-up sections we use self-adhered membranes rated for the pitch. If the original skip sheathing can’t hold modern fasteners, we overlay with solid plywood before any new roofing goes down. That’s a cost and calendar item we identify before the job starts, not a surprise mid-project.
A square is 100 square feet of roof area, so 24 squares means 2,400 square feet of roof surface. It matters because Foster City homes with low-slope sections and cathedral ceilings often measure more roof surface than the footprint suggests, and every square drives material and labor costs. The number also determines how much ice and water shield, underlayment, and flashing we quote. Our written estimate breaks it down by square, so you can see exactly what you’re paying for.
