AfterFast, Reliable Roof Inspection Across Tiburon
A roof inspection in Tiburon typically costs between $250 and $550 for a standard single-family home, and most inspections we schedule here are completed within 45 to 90 minutes on site. If you’re looking at a hillside or multi-pitch property above Richardson Bay, expect the job to run longer because there’s more roof to walk, more valleys to check, and more flashing to scrutinize. Call (361) 320-9467 and we’ll give you a written price before anyone sets foot on a ladder.
We’ve inspected roofs all over Tiburon, from the bay-facing slopes off Tiburon Boulevard to the custom builds around Paradise Drive and the mid-century homes near Reed Ranch Road. The common thread is salt air. It finds every piece of galvanized steel on the roof and starts working on it years before the shingles or tiles show any wear. That’s why our inspections here look past the surface and into the hardware, the underlayment, and the flashing details that fail first in this climate.
Why Brennan Roofing Is Tiburon’s Preferred Roof Inspection Company
Tiburon homeowners tend to ask the same question after a bad experience with another roofer: “Did they actually get up on the roof?” We did, and we have the moisture scan photos to prove it. Our Roof Inspection team walks every slope that’s safe to access, lifts tiles where the valleys meet, and checks the flashing at skylights, chimneys, and pipe penetrations. On bay-facing homes, we pay extra attention to the eaves and drip edge because that’s where the salt fog does its worst work.
Travis Oakley runs this location and holds the crew to The Garrison Code on every inspection: background-checked technicians, uniforms, boots on the roof, and a written report with photos before we leave the driveway. That matters in Tiburon because many of these homes have steep, multi-pitch roofs where a half-checked inspection is worse than no inspection at all.
Scheduling an inspection here doesn’t mean leaving a voicemail and hoping for a call back. A live person answers (361) 320-9467 around the clock. If you’re calling about a ridge vent that’s pulling loose on a windy afternoon above Richardson Bay, someone picks up on the first ring.
Roof Inspection Companies in Tiburon
Roof Inspection Companies in Tiburon aren’t all looking at the same things, and the difference shows up in the report you walk away with. A surface inspection here might tell you the tiles look fine and the shingles have some life left. A proper inspection tells you what’s happening underneath: whether the underlayment on that 1980s tile roof is still doing its job, whether the galvanized nails in the decking are rusting out from salt exposure, and whether the flashing at the valleys would survive another El Niño season.
For most residential homes in Tiburon, a full inspection with photos and a written summary runs $250 to $450. Add a moisture scan, which we recommend on any tile roof over 20 years old, and you’re at the higher end of that range. It’s money well spent when the alternative is discovering the problem through a water stain on the ceiling in January.
What Gets Checked on a Residential Roof in Tiburon
We inspect the surface materials first: cracked or slipped tiles, granule loss on composition shingles, and any split cedar shake. Then we move below the surface. On bay-facing homes, we pull back tiles at the valleys and eaves to check the underlayment and the nail condition. That’s where the hidden failures live in Tiburon.
When a Tiburon Homeowner Needs an Inspection
After a storm season is the obvious one. Before buying or selling is another, and plenty of Tiburon real estate transactions hinge on a clean inspection report. We also recommend an annual check on any home built before 1995, because that’s when original roofing assemblies here start showing the cumulative effects of salt fog and wind-driven moisture.
Commercial Roof Inspection in Tiburon
Commercial Roof Inspection in Tiburon covers a different set of needs than the residential work. The commercial properties here, the offices along Tiburon Boulevard, the shops near Main Street, the small multi-tenant buildings, often run flat or low-slope systems that collect standing water and trap salt residue after fog cycles. We inspect the membrane seams, the parapet flashing, and the drainage points where ponding water accelerates deterioration.
Commercial inspections in Tiburon usually run $450 to $900 depending on roof size and access. Property owners use these reports to plan capital budgets, satisfy insurance requirements, and negotiate maintenance contracts. We provide the documentation that actually helps in those situations: labeled photos, deficiency lists with severity ratings, and a clear recommendation for what to address now versus what can wait a season.
Low-Slope and Membrane Roofs
On flat and low-slope commercial roofs, the failure points are seams and penetrations. Salt fog accelerates corrosion on any exposed metal edging and fasteners. We check the pipe boots, the HVAC curb flashing, and the drain collars. A small seam split near a scupper can put water into the building for months before anyone notices on a roof that nobody walks.
Metal Roofing on Commercial Buildings
Some Tiburon commercial buildings have metal roofs, and those have their own failure mode here. The panel overlap points and the exposed fasteners take the brunt of the salt air. We look for rust bleed at the screw lines and worn seal washers. Replacing fasteners before they corrode through is far cheaper than replacing panels after they loosen and lift in bay wind.
Trusted Brands We Service in Tiburon
Tiburon homeowners ask us about material brands by name, and we work with the ones that hold up best in marine air. GAF and Owens Corning composition shingles cover many of the mid-century homes around town. For tile roofs, Atlas and Boral clay tile are common on the hillside builds. We keep fast-moving inspection and repair parts stocked for these manufacturers so we’re not waiting on a warehouse shipment when a Tiburon roof needs a flashing repair after a storm. If we find a brand-specific issue during an inspection, especially a known Boral tile weathering pattern on the bay-facing slopes, we’ll tell you exactly what it is and what it costs to fix.
Common Roof Inspection Problems We See in Tiburon Homes
- Salt-corroded flashing and fasteners. The fog off Richardson Bay deposits salt on every metal surface. Standard galvanized nails and flashing that would last 30 years inland can rust through in 15 to 20 years here on the bay-facing elevations.
- Failed underlayment hidden under intact clay tiles. We’ve pulled back perfectly good-looking Boral tiles on 1980s homes and found the felt underneath has turned to dust. The tiles shed water fine until a driving rain pushes it sideways at the valleys.
- Wind-lifted ridge vents and loosened fasteners. The constant bay wind works on vents, caps, and edge metal. Homes on exposed slopes above Paradise Drive see more of this than sheltered lots down near Reed School.
- Ponding water and debris buildup on low-slope sections. Multi-pitch Tiburon roofs often have a low-slope section or a flat deck transition. Fallen leaves from oaks and bays mix with fog moisture, clog drains, and hold water against the membrane.

FAQs About Roof Inspection in Tiburon
Because the tiles aren’t the waterproof barrier, the underlayment is. On many 1980s tile roofs above Richardson Bay, the clay tiles still look intact from the street but the felt underneath has disintegrated from years of salt fog and trapped moisture. A normal rain never reaches that layer, but an El Niño storm drives rain sideways at the valleys, and that’s when water finds the gaps. If you saw ceiling stains after last year’s heavy storms, call (361) 320-9467 and we’ll do a moisture scan before the next big front arrives.
Yes, and it’s a specific difference. Standard galvanized nails and zinc flashing corrode in this climate years before they would inland. On bay-facing Tiburon roofs, we specify stainless steel fasteners and either copper or high-grade aluminum flashing at the valleys, eaves, and penetrations. The coastal-spec hardware costs more up front, roughly 15 to 20 percent over the standard spec, but it avoids a repair cycle within a decade. We include these recommendations in every inspection report where it applies.
We use ridge-anchored safety gear and padded ladder standoffs, and we never walk on clay tile unless it’s absolutely necessary and safe to do so. On steep multi-pitch and cantilevered sections common to Tiburon hillside homes, the technicians will often work from the ridge line, at the valleys, and from ladder access at the eaves rather than putting full weight mid-slope. Travis Oakley’s crews are trained for steep-slope work and every technician is background-checked before they arrive at your home.
Ask for labeled photos of every deficiency, a severity rating for each one, and a written recommendation that separates immediate repairs from deferred maintenance. A flat-rate inspection that returns a one-page checklist isn’t enough on a Tiburon hillside roof. You want to see the valley flashings photographed, the underlayment condition documented where it was checked, and a specific note on fastener corrosion. Our reports include all of that, and we’ll walk you through it before we leave.
It is, mostly in the roof systems and the deliverable. Commercial roofs here are typically low-slope membrane or metal systems, and the inspection focuses on seams, penetrations, drainage, and the parapet details. The report is also different: property owners and managers usually need a deficiency list with cost estimates they can take to a budget meeting or an insurance carrier. We provide that format. Call (361) 320-9467 and we’ll quote the inspection on your Tiburon building directly.
