Fast, Reliable Roof Inspection Across Palo Alto
A standard roof inspection in Palo Alto runs $250 – $450 for most single-family homes, with Eichler and other flat-roof inspections at $350 – $650 because of the additional mapping and moisture testing involved. We schedule Palo Alto inspections within 5 – 7 business days in dry weather, and we always leave a written report with photos the same day. If you’re pricing an inspection because a buyer’s agent flagged the roof, or because you haven’t looked up there since the last rainy winter, call (669) 238-2101 and we’ll get a number on paper before anyone climbs a ladder.
Our crew works Palo Alto neighborhoods every week, from Professorville bungalows to the flat-roof Eichler tracts in Charleston Meadows and Greenmeadow. We know which roofs here carry original spray polyurethane foam, which have been retrofitted with lightweight tile over aging framing, and which sit close enough to the foothills that ember intrusion is a real concern. That local knowledge changes what we test, what we photograph, and what we flag in the report. It’s the difference between an inspection that checks boxes and one that tells you what your roof will actually do in the next big storm.
Why Brennan Roofing Co San Jose Is Palo Alto’s Preferred Roof Inspection Company
Brennan Roofing is an independently owned member of the Garrison Partners family, founded in 2000. Travis Oakley runs our operation, and every technician who shows up in Palo Alto is background-checked and in uniform. You’ll know the name of the person on your roof before they set a ladder. That’s part of The Garrison Standard: a written price before any work starts, a live person on the phone around the clock, and a one-year written guarantee on every job we do. The 365-Day Done Right Promise means if we miss something in an inspection and a repair fails within that year, we come back and make it right at no charge.
Palo Alto homeowners call us for inspections tied to real estate transactions, pre-winter checks, solar installation feasibility, and insurance questions. They tend to ask pointed questions and expect straight answers. We give them. The report you get isn’t a sales pitch, it’s a condition assessment with photos and a plain-English explanation of what matters now and what can wait.
One thing that sets us apart in Palo Alto: we work on flat and low-slope roofs without flinching. Most roofing companies in the Bay Area are shingle shops. We inspect foam roofs, membrane roofs, and modified bitumen systems as a matter of routine because Palo Alto has more of them than nearly any city in the region. That matters when the person on your roof needs to recognize foam delamination before it becomes decking rot.

Roof Inspection Companies in Palo Alto
Roof Inspection Companies in Palo Alto do not all offer the same thing, and it’s worth knowing the difference before you book. A basic inspection, sometimes called a visual inspection, involves walking the roof surface, checking flashings, chimneys, skylights, gutters, and pipe boots, then photographing the interior attic or crawlspace for water staining and ventilation problems. A comprehensive inspection, which is what most Palo Alto homes need, adds moisture testing on flat surfaces, granular loss evaluation on shingles, fastener pattern checks, and a written assessment against current California wildfire and Title 24 cool roof standards. That full inspection runs $250 – $450 for a typical pitched roof home, and $350 – $650 for an Eichler or other flat-roof property.
What a good inspection includes
The inspection should cover every roof penetration: vents, skylights, plumbing stacks, chimney flashing, and any solar standoffs. On a Palo Alto flat roof, it should also include a map of known patches and a walk to test for soft spots that indicate water-saturated foam. We give you that map in the report. You can see exactly where prior fixes were done, what condition they’re in, and whether the roof’s drainage still works after years of summer sun and winter rain.
We also check the drip edge and fascia. Those components get overlooked on a lot of flat-roof inspections, but they determine whether water sheds cleanly or wicks back under the roof edge during a heavy Pineapple Express storm.
When to book an inspection
Book before you buy, before you sell, before you install solar, and after any major wind event. If you live in the foothill-adjacent corridors along Page Mill Road or near the Los Trancos preserve, add “before wildfire season” to that list. A pre-September inspection that verifies ember-resistant vents and a Class A assembly can catch problems while there’s still time to fix them.
If your roof is more than about 15 years old, an inspection is a planning tool as much as a safety check. You’ll learn what’s wearing, what the anticipated lifespan is, and what a replacement would cost, so you can budget ahead instead of reacting to a leak.
Commercial Roof Inspection in Palo Alto
Commercial Roof Inspection in Palo Alto covers the low-slope membrane, foam, and mod-bit roofs on office buildings, retail pads, and multi-unit residential properties from California Avenue to the Stanford Research Park. These roofs differ from residential work in one important way: failure is measured in business interruption, not just repair cost. A commercial inspection in Palo Alto runs $450 – $900 for most buildings under 15,000 square feet, with larger footprints priced by the square foot after a site walk.
We inspect built-up roofs, TPO, EPDM, PVC, and spray foam systems on commercial properties. Each material fails differently. TPO seams can separate from thermal cycling after years of hot sun and cold nights. Foam roofs can lose adhesion and hold water. Mod-bit can alligator and crack. The report you get identifies the roof type, its age, its remaining service life, and a prioritized list of what to address now versus what to plan for in the next 24 months.
Drainage and ponding water
On Palo Alto commercial roofs, ponding water is the top issue we document. Flat commercial decks often have internal drains, and a single clogged scupper can hold water on the roof for weeks after a storm. That standing water degrades the membrane faster than anything else. Our inspection maps the drainage pattern and flags ponding areas with photos and measurements so you can see the problem with your own eyes.
Warranty and maintenance planning
Commercial roof warranties often require documented annual or semi-annual inspections. Skipping them can void coverage. We provide inspection reports that meet most manufacturer documentation requirements, and we’ll tell you plainly if your roof’s condition means a warranty claim is worth pursuing or if the better money is on targeted repair.
Trusted Brands We Service in Palo Alto
We inspect and service roofs built with materials from GAF, CertainTeed, Owens Corning, Atlas, and others, and we keep local stock for common Palo Alto repair parts. That means faster turnaround when an inspection turns up a cracked vent boot or a failed section of flashing. We work with asphalt shingles, architectural shingles, concrete and lightweight tile, standing seam metal, and the spray polyurethane foam systems that are everywhere in Eichler neighborhoods. For Palo Alto homeowners planning a re-roof, we explain options from Atlas and Tamko clearly, including what each line costs, how long it lasts, and how it weighs against what your structure can carry. We also install Boral roofing products, which some Palo Alto homeowners prefer for their fire resistance and lighter weight on older framing. The choice is yours; the explanation is ours.

AfterCommon Roof Inspection Problems We See in Palo Alto Homes
- Foam delamination on Eichler flat roofs. Original spray polyurethane foam roofs get patched over the years, but the underlying foam often loses adhesion from UV exposure and trapped moisture. Our crew inspected a flat-roof Eichler in the Charleston Meadows tract where the original foam roof had been patched four times. We mapped every penetration and valley, identified failed flashing around the skylight and a worn drip edge, and documented that the decking was sound but the foam had lost adhesion. The homeowner was surprised to learn their “modern” roof required a complete recoating to meet current wildfire and Title 24 cool roof standards.
- Water-saturated foam hiding decking rot. Foam roofs can absorb water for years without visible leaks. By the time staining shows on the ceiling, the decking underneath may already need replacement. Moisture testing during the inspection catches this early. In Palo Alto’s rainy winters, a small area of saturated foam can spread under the surface and compromise a much larger section by spring.
- Missing wildfire-resistant underlayment. Homes near the Los Trancos and Pearson-Arastradero open spaces, and along the foothill corridors like Page Mill Road, face real ember intrusion risk. An inspection that doesn’t check for ember-resistant vents, properly sealed penetrations, and a Class A assembly leaves you exposed. We verify these details against current fire code and flag every deficient item in writing.
- Nail pattern failures on architectural shingles. Palo Alto sits in a wind zone where architectural shingles need correct nailing patterns to hold their 130 mph wind rating. If a previous installer used too few nails or placed them high, the shingles can look fine from the ground but fail in the first strong storm. We check fastener patterns during the inspection, not just what the shingle surface looks like.

FAQs About Roof Inspection in Palo Alto
An Eichler inspection in Palo Alto needs to map every roof penetration, test for foam adhesion loss, check for water-saturated foam, and assess the condition of the drip edge and skylight flashings. Most Eichler roofs are original or re-coated spray polyurethane foam, and the failure mode is not missing shingles. It’s hidden delamination. Our inspection includes a petrographic-style map of patches, moisture tests at each penetration, and a written note on whether the roof needs recoating or full replacement. Call (669) 238-2101 for a flat-roof inspection price.
A Palo Alto inspection needs to verify ember-resistant vents, Class A assembly compliance, and structural readiness for solar panels, which includes checking the roof deck, framing, and attachment points. If you’re in a foothill-adjacent neighborhood like those near Page Mill Road or the Arastradero Preserve, wildfire hardening is not optional under current code. Our inspection flags missing ember-resistant components, non-compliant underlayment, and any roof condition that would complicate a solar installation. We document everything in the written report so you have evidence for your insurance company or solar contractor.
Foam roofs lose adhesion from prolonged UV exposure even when the surface looks intact, and patches only address isolated areas, not the underlying aging of the foam system. In Palo Alto’s dry, sunny summers, the top layer of foam degrades steadily, and small patches don’t stop that process. A recoat restores the protective elastomeric layer across the entire roof and can extend its life by 10 – 15 years if the decking is still sound. Our inspection tells you whether recoating is enough or if the foam has already begun to fail in ways that require replacement. Call (669) 238-2101 for a condition assessment with photos.
Commercial flat roofs in Palo Alto are typically built-up, TPO, EPDM, or modified bitumen over larger decks with internal drains, while residential Eichler roofs are usually spray polyurethane foam with different drainage and adhesion concerns. The inspection method differs too. Commercial work involves checking seams, membrane integrity, drain function, and ponding water, plus warranty documentation requirements. Eichler residential inspections focus on foam adhesion, penetration mapping, and recoating timing. We do both, and we write each report for the roof type in front of us, not from a template.
An inspection gives you the exact roof measurements, decking condition, and current material type, which lets us price architectural shingle replacement accurately and order materials before the job starts. Lead times on premium architectural shingles from lines like Atlas and Tamko can run several weeks. If you wait until the leak appears to order, you’ll be waiting longer. A proactive inspection puts the number in writing now, so when the time comes to replace, the price is already fixed and the materials are already on order. Call (669) 238-2101 to schedule yours.
