A roof inspection in Sebastopol typically costs between $180 and $340, and it is the single most effective way to catch small problems before the first October rain turns them into active leaks.

Call (361) 320-9467 to schedule yours.
Sebastopol sits in a Mediterranean climate: hot, dry summers that bake shingles and flashing for four straight months, then wet winters that arrive suddenly and test every penetration. That thermal cycling is brutal on roofing. What holds up through August often fails by late October. Homeowners who book an inspection in September get a written picture of their roof’s real condition before the rain does the revealing for them.
Why Brennan Roofing Is Sebastopol’s Preferred Roof Inspection Company
Sebastopol homeowners call us because our inspections are documented, specific, and priced in writing before any repair work is approved. We do not hand you a vague verbal summary. You get a written report that names what we found, where we found it, and what it costs to fix. That discipline comes from The Garrison Standard, the operating code every Brennan Roofing location follows: background-checked, uniformed technicians who arrive inside the promised window and put the price on paper before any work starts.
Our Roof Inspection team has walked more Sebastopol roofs than we can count, and the reviews from local customers reflect it. Homeowners consistently mention the same three things: the tech showed up on time, the report was easy to understand, and there was zero pressure to approve anything. We serve Sebastopol directly, with crews that know which neighborhoods have original wood shingles and which have standing-seam metal that has been patched half a dozen times.
Every inspection is performed by a trained, background-checked technician in uniform. You know exactly who is on your roof, and you know what they found when they come down.
Free Roof Inspection in Sebastopol
A free roof inspection in Sebastopol is the right starting point when you are buying a home, preparing for fire season, or noticing stains on ceilings after rain. We walk the entire roof surface, check flashing at chimneys and valleys, inspect the gutter and drainage system, and document everything with photos. You get a written report and a clear recommendation, whether that means a minor repair or a full replacement. There is no charge for the inspection itself.
What We Check On Every Sebastopol Roof
We check flashing first. Cracked or separated flashing at chimney penetrations and valleys is the most common failure point on older Sebastopol homes, and it is exactly what fails when the first atmospheric river pushes rain sideways. We also probe for soft decking, especially on historic farmhouses where original wood shingles have been layered over and the underlayment underneath has been rotting quietly for years.
When To Schedule Your Free Inspection
September is the smartest month in Sebastopol. The dry season has done its damage, and you still have time to schedule repairs before the first big October storm. If you have already seen leaks, call sooner. A scheduled inspection is cheaper than an emergency Roof Repair in Sebastopol call after water has poured through your ceiling.
Roof Inspection Companies in Sebastopol
Roof inspection companies in Sebastopol are not all the same, and the difference shows up when the report comes back. Many companies check only the field shingles, the large visible surface. That is a problem here, because the failures that hit Sebastopol hardest are the ones hidden at penetrations and valleys, the exact spots the first October rain exposes. We inspect the full system: field, flashing, decking, underlayment, drip edge, and drainage.
What Sets Our Reports Apart
We document soft spots with photos and mark them on a diagram you can actually read. If we suspect rot under an older roof, we say so plainly, and we explain what it would cost to open that section and confirm. Homeowners tell us they have never seen this level of detail from another roofer, and that is deliberate. The report is the product.
Inspection First, Price In Writing
The Garrison Standard applies to inspections too. If we find damage, the repair price goes on paper before any work starts. You approve the number, then we touch the roof. No work at the door, no price movement, no change orders you did not see coming.
Trusted Brands We Service in Sebastopol
We install and service roofs built with GAF, CertainTeed, and Owens Corning materials, and we stock the most common repair parts for these lines locally so a Sebastopol inspection that turns up minor damage does not turn into a two-week wait. If your roof is a standing-seam metal system or a fire-rated composition roof on a hillside estate, we service those too. Older wood shingle roofs get the same honest assessment: repair what is repairable, replace what is not, and price it all in writing.
Common Roof Inspection Problems We See in Sebastopol Homes
- October leak surprises from cracked flashing. Flashing around chimneys and valleys cracks during hot, dry summers. The first heavy October rain finds those cracks, and a ceiling stain follows within 24 hours. September inspections catch this before the damage spreads.
- Hidden decking rot under historic wood shingles. Many downtown Victorians and farmhouse cottages have original wood shingles layered under newer coverings. The underlayment beneath them rots silently, and the decking below often goes soft. Probing is the only way to know before tear-off.
- Misleading “clean” reports from field-shingle-only checks. A report that only checks the visible shingle surface can miss everything that matters on an older Sebastopol roof. Cracked mastic at penetrations, failed valley flashing, and blocked drainage all hide outside the field.
- Unflagged permit-required upgrades. When a repair turns into a tear-off, Sebastopol’s code requirements can trigger upgrades to ventilation, drip edge, and starter strip. We flag these during the inspection, so the written price already includes them, not a surprise later.

FAQs About Roof Inspection in Sebastopol
October is the collision point in Sebastopol. Months of hot, dry summer weather bake shingles and flashing until they crack, and the first atmospheric river of fall arrives before most roofs have recovered. Water finds the cracks immediately, and leaks appear within 24 hours of the first heavy rain. That is why we recommend September inspections here. Call (361) 320-9467 to schedule yours before the storm does the scheduling for you.
A free inspection on an older Sebastopol home includes walking the full roof surface, checking flashing at every chimney and valley, probing for soft decking, inspecting gutters and downspouts, and documenting everything with photos you receive in the written report. We pay special attention to the spots where century-old framing meets newer repairs, because that is where rot hides. If you have an older home and want to know what is actually up there, call (361) 320-9467.
We price an allowance for it in the written quote before we open anything. If the inspection suggests rot in a specific area, the contract includes a line item for opening that section and a worst-case number for replacement decking or framing repair. You approve the allowance in writing, and we do not exceed it without your written sign-off. No surprises, no door-price adjustments. Call (361) 320-9467 for the details.
An inspection alone does not trigger permits. But if the inspection uncovers damage that requires a tear-off, Sebastopol’s building code may require upgrades to ventilation, drip edge, starter strip, or ridge venting as part of the repair. We flag these during the inspection and include them in the written price, so you know the full cost before any work starts. Call (361) 320-9467 to have your roof assessed.
Yes. We regularly inspect fire-rated composition roofs, standing-seam metal, and high-end architectural shingle systems on vineyard estates and custom homes throughout Sebastopol. These roofs need the same disciplined inspection as any other, especially where ember risk and aesthetics both matter. We service GAF, CertainTeed, and Owens Corning systems and document wildfire-resilience concerns alongside standard roof condition. Call (361) 320-9467 for a free estimate.
