Why Brennan Roofing Co San Jose Is Redwood City’s Preferred Roofing Company
Redwood City homeowners call us because we run every job by The Garrison Standard: background-checked, uniformed technicians, a written price before any work starts, and a guarantee that doesn’t expire when the truck pulls away. Most of the work we do here is on mid-century ranch homes, especially in neighborhoods like Woodside Plaza, Redwood Village, and the streets east of El Camino Real. Those roofs have a specific set of failure points, and we know them by address, not just by zip code. Reputation here is built one roof at a time, and we hold every technician to The Garrison Code on every single job. Dispatch and scheduling are coordinated from the brand’s San Francisco Bay Area office, but the crews serving Redwood City work locally, and they answer to Travis Oakley, who runs our operation directly.
Styles & brands we work with






Roofing Contractor in Redwood City
A roofing contractor in Redwood City does more than nail shingles. On the housing stock here, the job usually starts with figuring out what is actually under the surface. Many Redwood City homes from the 1950s and 60s have original built-up gravel roofs that have been over-coated so many times the roof jacks are buried and the scuppers are clogged with redwood needles. A proper contractor job here means tearing down to the deck to see what is rotted, then rebuilding the drainage and flashing before the new roof goes on. A full roof replacement in Redwood City typically runs $12,000 to $22,000 depending on size and condition, while a targeted repair on flashing or a clogged scupper usually lands between $350 and $900.
Deck Evaluation and Material Selection
Before any new underlayment goes down, we assess the deck, the drip edge, and the drainage path. On a Redwood City ranch with multiple over-coats, that often means cutting back built-up layers to find the original sheathing. We install materials from GAF, CertainTeed, and Tamko, chosen for how they handle both long dry spells and sudden downpours. The price goes on paper before we remove a single shingle, and it does not move at the door.
Permit and Inspection Coordination
Redwood City requires permits and inspections for full tear-offs and structural work, and we pull them. We document the nailing pattern, the flashing details, and the wind rating the city asks for. A compliant roofing contractor in Redwood City shows up with a plan that passes inspection the first time, not a change order halfway through.
Commercial Roofing in Redwood City
Commercial roofing in Redwood City means low-slope membrane and built-up systems on buildings that frequently sit under mature redwood trees. The same needle-clogged scuppers that plague residential ranch homes become a worse problem on commercial flat roofs, where ponding water can sit for days after a storm. We handle commercial repair, replacement, and maintenance for property managers and owners across Redwood City, from El Camino Real storefronts to office parks near Highway 101. A commercial roof repair here typically runs $900 to $3,500 depending on the membrane and the extent of ponding damage, while a full commercial replacement usually lands between $8 and $14 per square foot.
Flat and Low-Slope Systems
Commercial buildings in Redwood City need drainage that works, not just a membrane that holds water. We inspect scuppers, roof jacks, and parapet flashings before recommending any repair, because a clogged drain under a November atmospheric river is a failed roof waiting for a tenant complaint.
Preventive Maintenance Contracts
For commercial property owners in Redwood City, we offer maintenance visits that clear scuppers, inspect seams, and document conditions. The goal is simple: catch the small failure before it becomes a flooded suite and a five-figure claim. Every maintenance report is written, and every repair comes with the same written guarantee.
Trusted Brands We Service in Redwood City
We install and service roofing systems from GAF, CertainTeed, Tamko, and Boral, and we stock common repair parts for Redwood City homeowners. When a GAF shingle roof in Redwood Village needs a patch before a storm, we don’t order parts from a warehouse three states away. Material choice is explained plainly: what each brand offers, what it costs, and what makes sense for a low-slope ranch versus a hillside custom home. You choose with confidence because you see the real options, not a salesman’s talking points.

AfterCommon Roofing Problems We See in Redwood City Homes
- Clogged scuppers and buried roof jacks. The ‘Redwood City special’ is a 1960s ranch where the built-up gravel roof has been over-coated so many times the drains are buried. We see it on Woodside Plaza ranches and mid-century tracts throughout the city, and the fix is a tear-off plus drainage rebuild, not another coat.
- Ponding on low-slope roofs. Redwood City’s Mediterranean climate means months of dry, then sudden atmospheric rivers. Low-slope roofs pond water when scuppers clog, and that water works its way into ceilings. Proper drainage retrofits stop it.
- Dry-rotted fascia and soffit under overhangs. Minimal overhangs on 1950s and 60s tract homes leave fascia exposed to winter storms and summer sun. Once rot starts behind the drip edge, water follows the framing. We replace rotted wood before installing new flashing and shingles.
- Missing or failed flashing at roof jacks. The roof jacks around plumbing vents and furnace flues on mid-century Redwood City homes are a common leak point. When we find them buried under over-coats, we cut them out correctly and install new flashing with a documented seal.
Pricing for Roofing Company in Redwood City, CA
Here are honest ranges for Redwood City, not national averages. A targeted roof repair on flashing, a scupper, or a small leak runs $350 to $900. A full tear-off and replacement on a typical 1,400 to 1,800 square foot Redwood City ranch runs $12,000 to $22,000, depending on whether we need to replace decking, rebuild soffit, or reroute drainage. Commercial flat roof repair lands between $900 and $3,500, and a full commercial replacement typically costs $8 to $14 per square foot.

FAQs About Roofing Company in Redwood City
Redwood City shingle roofs must meet a design wind load of roughly 110 to 130 mph depending on exposure and roof height, and verification comes from the manufacturer’s installation instructions combined with the nailing pattern documented in the permit record. We install architectural shingles with a documented 130 mph wind rating when specified, and we photograph the fastener spacing and flashing details before the final inspection. Call (669) 238-2101 and ask for the wind-rating documentation that goes with your quote.
Yes, Redwood City requires a permit for a full tear-off and roof replacement, and the building department schedules an inspection after the underlayment and flashing are installed. We pull the permit, schedule the inspection, and show up with documentation the inspector can verify. A cheap bid that says otherwise is skipping a required step and leaving you exposed on insurance claims.
The defining problem is clogged scuppers and buried roof jacks on minimal-overhang, low-slope roofs built in the 1950s and 60s, worsened by redwood needle accumulation from the native trees. We fix them by cutting the over-coats back to the original deck, rebuilding the scupper openings, and installing new drainage paths before any membrane or shingle goes down. It is slower than a nail-over, and it is the only way the water stops.
We provide a written close-out package that includes the manufacturer’s wind-rating certificate, the nailing pattern, flashing details, and photographs from before, during, and after the installation. That documentation is what your insurer needs to verify the roof was compliant when a storm claim comes through. The package is yours at no extra charge, and we keep a copy in our records.
A compliant quote includes the permit fee, deck evaluation, scupper and drainage repair, Ice & Water Shield at eaves and valleys, flashing replacement at every roof jack, and wind-rating documentation for the final inspection. A cheap postcard bid usually covers shingles and labor only, leaving you to discover the rotted deck and clogged scuppers as a change order after the old roof comes off. Call (669) 238-2101 for a written quote that shows every line item before any work starts.
