AfterFast, Reliable Roofing Company Across Corte Madera
Brennan Roofing is a Roofing Company that works on Corte Madera roofs every week, and we know what this town’s air does to a roof. The marine layer off Richardson Bay and the Corte Madera Marsh carries salt and moisture that eats standard galvanized fasteners and rots decking faster than homeowners expect. We answer the phone live, write the price down before any work starts, and back every job with our 365-Day Done Right Promise in writing. Call (361) 320-9467 to schedule a free roof estimate in Corte Madera.
Why Brennan Roofing Is Corte Madera’s Preferred Roofing Company Company
Homeowners in Corte Madera call us after another roofer no-shows or changes the number at the door. That does not happen here. Travis Oakley runs every job to the Garrison Standard: written price before work begins, background-checked uniformed technicians, and a full-year written guarantee. We do not ask you to trust a handshake. We put the price, the scope, and the warranty on paper before a single shingle comes off.
Our crews know Corte Madera’s housing stock: low-pitch 1950s and 1960s ranch homes off Tamalpais Drive and Pixley Avenue, split-levels near Madera del Presidio, and newer infill along the 101 corridor. We know that the homes backing the creek and marsh get rot at the north-side bottom course first. That local knowledge changes how we bid and how we build, and it is why Corte Madera homeowners keep our number.
Roof Coating in Corte Madera
Roof coating in Corte Madera is a practical option for flat and low-slope roofs that still have sound decking but aging surfacing, and it typically runs $2.50 – $5.50 per square foot here depending on the product and number of coats. A silicone or acrylic coating seals hairline cracks, reflects the intense summer sun that bakes south-facing planes above the fog line, and buys five to ten years before a full replacement. Corte Madera homeowners with modified bitumen or built-up roofs on 1960s ranches near the marsh should consider coating before the wet season, because standing moisture accelerates surface degradation.
When Coating Makes Sense in Corte Madera
If your roof’s seams are tight and the decking is dry, a coating is a fraction of the cost of a tear-off. We inspect first. We will not coat over wet or rotted decking, and we will tell you plainly if coating is throwing money at a roof that needs replacement. Travis Oakley’s crew checks the north slope carefully on Corte Madera homes, because that is where hidden moisture hides on homes near the creek corridor.
Coastal-Spec Coatings
We specify high-solids silicone coatings with marine-grade primers on Corte Madera roofs, not the basic acrylic sold inland. Salt air off the marsh is hard on budget coatings. The coastal spec costs about $0.75 – $1.00 more per square foot up front and lasts several years longer. That math works for most homeowners once they see it.
Free Roof Estimate in Corte Madera
A free roof estimate in Corte Madera means we come out, get on the roof, and hand you a written line-item price for the work, whether it is a repair, coating, or full replacement. There is no charge and no obligation. We serve all of Corte Madera, from the Madera del Presidio neighborhood south of Tamalpais Drive to the creek-adjacent streets near the Village at Corte Madera, and we schedule estimates around your day, not ours.
What the Estimate Includes
Every Brennan Roofing estimate is written before any work starts. It lists the materials by brand name, the fastener spec, the underlayment, the flashing plan, and the labor. You will see exactly what we are installing and what it costs. No allowances. No vague line items. No price that moves at the door.
Why We Inspect the North Slope First
On Corte Madera homes near the marsh and creek, we pull the bottom course on the north side before we write the number. If the sheathing is soft, the price reflects replacing it and adding a self-adhered membrane. A roofer who skips that step writes a cheap number and then hits you with a change order. We would rather give the honest number the first time.
Trusted Brands We Service in Corte Madera
Brennan Roofing installs materials from GAF, CertainTeed, and Owens Corning, and we stock the fasteners and flashings those systems require for Corte Madera’s bay air. If you have a GAF architectural shingle roof that is failing around the valley flashings, we can match the product and repair it correctly. If you want a standing-seam metal roof from a manufacturer rated for coastal exposure, we will show you the options and explain the fastener spec. Parts for common Corte Madera roof systems are locally available, so repairs move quickly.
Common Roofing Company Problems We See in Corte Madera Homes
- Rust bleed at fasteners. Standard electro-galvanized nails on a roof exposed to salt-laden air off Richardson Bay start rusting within a few seasons, and the rust stains run down the shingles before the nail heads fail. We spec hot-dip galvanized or stainless fasteners on every Corte Madera install.
- North-side bottom course rot. Homes backing the Corte Madera Creek or the marsh get fog-driven moisture that never fully dries, and the rot climbs into the lower three to four feet of decking before it ever shows as a ceiling stain. This requires cutting out and replacing sheathing, not just overlaying shingles.
- Wood shake tear-offs done wrong. Many 1950s and 1960s Corte Madera ranches still have original wood shake under a layer of architectural shingles. Nailing new shingles over old shake traps fog moisture against the decking and hides soft spots around penetrations. The correct fix is a full tear-off to the deck.
- Mild-steel flashing pitting. Drip edge, valley flashing, and standing-seam panels on Corte Madera roofs need Corten steel or marine-grade aluminum. Mild steel pinholes within a decade in this air, and the leaks start at the flashing long before the field shingles fail.
Pricing for Roofing Company in Corte Madera, CA
A full roof replacement in Corte Madera typically runs $18,000 – $34,000 for a standard 1,800 – 2,400 square foot ranch, with the coastal spec adding $1,500 – $3,000 for marine-grade fasteners, self-adhered membrane at the north bottom course, and upgraded flashing. Roof repair in Corte Madera runs $450 – $1,800 for typical flashing, valley, and penetration work. Roof coating runs $2.50 – $5.50 per square foot. The price gap between the coastal spec and the inland spec is real, and we will show you that number in writing. Call (361) 320-9467 for a free estimate.
We wrote this page for Corte Madera specifically because the Corte Madera market prices differently than San Rafael or Mill Valley. Salt air and marsh fog drive the cost. The cheap inland spec costs more within a decade when the fasteners rust out and the north-side decking rots. We price the job correctly the first time.

FAQs About Roofing Company in Corte Madera
The north side never dries. Fog off the marsh and creek sits on that plane, and moisture wicks into the bottom course and climbs into the lower decking. The leak that shows on your ceiling is often the exit point, not the entry point. We pull the bottom course on the north side during every Corte Madera estimate. Call (361) 320-9467 for a free inspection and a written price if we find rot.
You need hot-dip galvanized at minimum, and stainless for standing-seam metal and exposed flashing. Standard electro-galvanized nails rust out in this bay air in a few seasons. The upgrade costs a few hundred dollars on most Corte Madera homes. The cheap spec costs a full re-roof within a decade.
Expect to pay $1,500 – $3,000 more for the coastal spec on a full replacement. That covers marine-grade fasteners, a self-adhered ice and water shield two courses up the north slope, and Corten or marine-grade flashing. The inland spec saves money on day one and costs more over ten years. We will put both numbers on the estimate so you can see the difference.
Moisture from the ground and the air both attack the decking, so we treat the north slope and the penetrations as high-risk. We add self-adhered membrane at the bottom course and inspect the sheathing around vents and pipes before we write the number. Homes on former marshland need better ventilation too. We will recommend the right intake and exhaust for your roof.
If the decking is sound and the shingles are simply weathered, a coating can buy five to ten years. If the shingles are cracked, cupping, or missing granules down to the mat, coating will not stop the leaks. We inspect for free and tell you which one you need. Call (361) 320-9467 to schedule the estimate.
