Fast, Reliable Roof Inspection Across Corte Madera
A standard roof inspection in Corte Madera runs $195 – $395, depending on roof size, pitch, and access. We schedule most inspections within 3 – 5 business days, and you get a written report with photos the same day. Call (361) 320-9467 to book a visit from a background-checked, uniformed technician who knows Corte Madera’s fog belt, marshland lots, and mid-century construction. No door-knocking. No pressure. Just an inspection that tells you exactly what you have.
Corte Madera roofs don’t age like roofs in Novato or San Rafael. The marine fog off Richardson Bay keeps north slopes damp until midday, and the salt air from the marsh corrodes flashing and fasteners. That’s why every inspection we do here accounts for moisture wicking, underlayment condition, and ventilation, not just shingle wear. We’re not a faceless call center. We’re an independently owned member of the Garrison Partners family, founded in 2000, and we operate under The Garrison Standard: written price before any work starts, background-checked technicians, and a 365-Day Done Right Promise in writing.
Why Brennan Roofing Is Corte Madera’s Preferred Roof Inspection Company
Homeowners across Corte Madera from Madera del Presidio to the neighborhoods along Tamalpais Drive call us because our inspections catch what generic checklists miss. We know that homes backing up to the Corte Madera Creek and the marshlands show rot at the bottom course of the north slope first. Fog-driven moisture never fully dries there, so a small stain near a plumbing boot can hide three feet of soft sheathing underneath. That’s a Corte Madera-specific failure mode, and it’s exactly what our Roof Inspection team is trained to find.
We dispatch from our San Francisco Bay Area office, and crews serve Corte Madera locally. When you call, a live person answers. Not a voicemail tree. Not a chatbot. Travis Oakley sets the standard for every job: the price goes on paper before any work starts, and it does not move at the door.
Reviews from Corte Madera customers consistently mention the same three things: the technician showed up inside the promised window, the report was detailed enough to hand to an insurance adjuster, and nobody tried to upsell a full tear-off when a repair would do. That’s the reputation we’ve built here, one inspection at a time.
Roof Inspection Services in Corte Madera
Roof Inspection Services in Corte Madera cover the full roof system: shingles or tile, underlayment, flashing, drip edge, vents, gutters, and any penetrations like skylights, plumbing boots, or attic fans. A visual inspection of a single-story ranch in Corte Madera typically runs $195 – $295. If you need a more detailed assessment that includes attic access, moisture meter readings, and a full photo report, expect $295 – $395. Every inspection ends with a written summary and a straight answer about what needs attention now, what can wait, and what it will cost to fix.
What We Check on Every Inspection
We inspect the shingle field, valleys, ridge lines, and every penetration. We look for granule loss, cupping, curling, missing tabs, and wind damage. But in Corte Madera, we go further. We check the lower three to four feet of the north slope for wicking and soft decking. We inspect the drip edge for corrosion from salt air. We look at the underlayment condition at the eaves, because failed felt on a fog-belt roof means water is getting under the shingles even when the surface looks fine.

When You Need One
Book an inspection after any big winter storm, before you buy a home, or when you notice a ceiling stain you can’t explain. If your roof is over 15 years old and sits on a former marsh lot, schedule one on a dry morning. The report tells you the real remaining life, not the optimistic guess a quick drive-by gives you.

Hail Damage Roof in Corte Madera
Hail Damage Roof inspections in Corte Madera are less about the big Texas-style hail and more about the smaller, wind-driven hail that hits during Pacific storm fronts. That hail rarely punches through shingles. What it does is bruise the shingle mat, knock granules loose, and leave the asphalt exposed to Corte Madera’s intense summer UV. A hail damage assessment in Corte Madera runs $250 – $395, and we document every hit with close-up photos so you can file an insurance claim with real evidence.
What Hail Damage Looks Like Here
On a south-facing plane above the fog line, hail damage shows up as radial cracks or small divots where granules were knocked out. On a mossy north slope, it can be harder to spot. We check ridge caps, soft metal vents, and gutters for denting. Hail often leaves its clearest signature on the aluminum, not the shingles themselves. That’s the trick inspectors from drier inland markets don’t always know.
Insurance and Documentation
If hail damage is present, we document it thoroughly. Every photo is timestamped, every affected plane is marked, and the report is written so an adjuster can use it without additional back-and-forth. We don’t tell you to file a claim. We give you the facts and let you decide. If repairs are needed, a written quote follows, and the price does not change once you approve it.
Trusted Brands We Service in Corte Madera
We service and install materials from GAF, CertainTeed, and Owens Corning, which means the shingles on your Corte Madera home are backed by a real manufacturer warranty, not a handshake. When an inspection finds damage to a GAF architectural shingle roof, we can match the color in most current product lines. Same with CertainTeed and Owens Corning. We keep a local inventory of matching ridge caps, starter strips, and flashing components in the Bay Area, so a repair doesn’t stall because a part had to ship from three states away. If you’re not sure what brand is on your roof, our inspection report includes that information.
Common Roof Inspection Problems We See in Corte Madera Homes
- North-slope rot at the bottom course: Marine fog keeps the lower shingles damp well into the afternoon, and over decades the sheathing beneath them wicks moisture upward. A small stain near the eave often means the bottom three feet of decking is soft to the screwdriver.
- Corroded drip edge and flashing from salt air: Homes near the Corte Madera Marsh and Richardson Bay corridor get salt-laden marine air funneled directly onto their roofs. Galvanized drip edge and pipe boots corrode years faster here than in San Rafael.
- Failed underlayment on low-pitch ranch roofs: The 1950s and 1960s tract homes on former marsh and creek-bottom land rarely have enough slope to shed water quickly. Once the original felt underlayment fails, water sits against the decking and rot spreads under shingles that still look fine from the ground.
- Moss and algae on north planes: Corte Madera’s fog belt keeps north-facing roofs damp for months at a time. Moss lifts shingle edges, traps water, and creates a permanent moisture bridge against the decking. A standard dry-climate inspection won’t flag it as a structural issue, but we do.
Pricing for Roof Inspection in Corte Madera, CA
A visual roof inspection in Corte Madera runs $195 – $295 for a single-story ranch. A more detailed inspection with attic access, moisture testing, and photo documentation runs $295 – $395. Larger split-level homes or properties with detached ADUs and shops on county-regulated lots run toward the top of that range because there’s more roof plane to inspect and more penetrations to verify.

FAQs About Roof Inspection in Corte Madera
Because Corte Madera sits in a fog belt. The marine layer off the bay keeps north-facing roof planes damp until midday for much of the year, and marine air from the Corte Madera Marsh adds moisture and salt. Moss and algae thrive in that persistent dampness, especially on the lower courses where water drains slowly. It’s not a cleanliness problem. It’s a microclimate problem, and the fix usually involves improved ventilation, strip shingles at the eave, or a treatment plan specific to Marin’s coastal fog. Call (361) 320-9467 and we’ll tell you what your roof needs.
An inspection itself requires no permit. Repairs that touch the roof system, especially on larger Corte Madera lots that fall under county permitting and septic or well setback rules, may. We verify permit requirements before quoting any repair, including outbuilding roof tie-ins and drainage away from septic fields. Skipping that step can leave you with an unpermitted repair that becomes a problem when you sell. We scope it before we quote it.
We inspect it from the deck, not just from the attic or a drone. Low-slope ranch roofs on former marsh and creek-bottom land show moisture damage from the underside of the sheathing first, and you can’t see that from a drone. We walk the roof where safe, check for soft spots with a moisture meter, and inspect the eave details where wicking starts. That’s the only way to catch decking rot before a full tear-off becomes the only option. Call (361) 320-9467 to schedule one.
Yes, and most Corte Madera homeowners combine them. A standard inspection covers the roof system, and the hail damage assessment adds bruise detection, granule-loss mapping, and documentation for an insurance claim. You pay one visit fee, not two. Book the combined inspection and you’ll get a single report covering everything, including the hail-specific photos an adjuster needs.
A Corte Madera-specific report should include the condition of the lower north-slope courses, underlayment status at the eaves, drip edge corrosion from salt air, moss and algae mapping, decking moisture readings, and any outbuilding roof tie-ins or drainage concerns on county-regulated lots. Generic checklists skip all of that. Our reports include it because those are the failure points we actually find on Corte Madera roofs. Call (361) 320-9467 for an inspection report that reflects the roof you actually have, not a template.
