AfterFast, Reliable Roof Inspection Across Napa
A roof inspection in Napa typically costs $180 to $450 for a standard home, and $450 to $1,200 for acreage properties with outbuildings, detached ADUs, or winery estate roofs that require thermal imaging and ember-resistant detailing verification. Most inspections take 60 to 90 minutes on site, with a written report delivered the same day or next morning. If you own a home in Napa, you already know the stakes changed after the 2020 Glass Fire: your roof isn’t just keeping out rain, it’s your first line of defense against wind-driven embers coming off the Mayacamas. Call Brennan Roofing at (361) 320-9467 to schedule your inspection.
Our Roof Inspection team knows Napa’s housing stock and fire codes. We walk roofs in Alta Heights, Browns Valley, Silverado, and the neighborhoods along Browns Valley Road and Coombsville Road every week. We know what a 1920s bungalow on a downtown Napa lot needs versus a 1990s tile roof on a Silverado estate. The inspection is different, and so is the report.
Why Brennan Roofing Is Napa’s Preferred Roof Inspection Company
Napa homeowners call us because we show up with a plan and a written price before any work starts. Travis Oakley runs our Napa roofing crew under the Garrison Standard: background-checked, uniformed technicians inside the promised window, a written inspection report you can hand to your insurer, and no price that changes at the door.
Our local reputation in Napa comes from specific, verifiable practices. Every inspection includes a walk of the roof surface, flashing, drip edge, vents, and gutter conditions. On Napa properties with clay or concrete tile, we also check the batten cavities and underlayment, which is where the 1990s-era roofs in Silverado are failing right now. If we find something, you get a line-item written quote. If we don’t, you get a clean report and a straight answer.
Roof inspection companies in Napa vary in what they check. Some walk the roof and take photos from the ladder. We carry thermal-imaging cameras on Napa inspections because hot embers and hidden moisture don’t show up in a standard photo. You’ll hear more about that below.
Free Roof Inspection in Napa
Brennan Roofing offers a free roof inspection in Napa when you’re evaluating a roof after a red-flag event, before a sale, or because you’re not sure what condition the roof is actually in. The free inspection is a visual and thermal walk of the roof surface, flashing, vents, drip edge, and any visible underlayment at the eaves. If the inspection turns up repair or replacement work, the written quote you get covers that work in full detail. No cost to you for the inspection. No obligation to move forward.
When a Napa homeowner needs a documented, insurance-grade inspection with a formal report, thermal imaging of tile batten cavities, and ember-resistant detailing verification, we charge $450 to $1,200 depending on roof complexity, number of structures, and access. That’s the honest range. You’ll know the exact number in writing before we schedule the on-roof work.
What the free walk covers
We inspect the roof surface material, step and counter flashing, drip edge, eave and ridge vent screens, gutter runs, and downspout discharge points. On tile roofs, we also look at bird stops and the visible underlayment at the eaves. The walk takes 45 to 60 minutes on a standard single-family home in Napa.
When a Napa homeowner should schedule it
After a red-flag wind event, before listing a home, right after a heavy winter rain, or when you notice ceiling stains, granule loss in gutters, or lifted flashing. In Napa County, the smarter time is before fire season, not after smoke fills Browns Valley Road.
Roof Inspection Companies in Napa
Roof inspection companies in Napa typically charge $180 to $450 for a standard home inspection and more when the property includes outbuildings, a detached ADU, or steep-access tile roofs. What separates one from another is whether the inspector actually looks at ember-resistant detailing and drainage, or just checks shingle wear.
Brennan Roofing is the only Napa-area company we know of that scopes acreage inspections around county permitting, septic and well setbacks, and long material haul distances before quoting repair work. That matters because a roof over a detached shop and ADU on an open lot has different inspection points than a downtown bungalow. The report should reflect that.
Thermal imaging on Napa acreage
On acreage properties, we walk every structure: the main house, the detached shop, the ADU, and any covered equipment sheds. We use thermal cameras to find hidden moisture under tile and hot ember signatures in batten cavities after a red-flag event. A standard ladder-and-photo inspection misses all of that.
Payment and documentation
You get a written report and a written price for any recommended work. Payment for inspection services is due at the time of the inspection unless we’ve agreed otherwise in writing. The report is yours. We don’t hold it hostage for the repair quote.
Trusted Brands We Service in Napa
We service and inspect roofs built with GAF, CertainTeed, Owens Corning, and IKO materials. When a Napa roof inspection turns up failed shingles or underlayment on a CertainTeed or Owens Corning roof, we can pull repair materials fast because we work directly with manufacturer distribution. For GAF and IKO systems, we match the original spec, not a generic substitute. If you’re in Napa and you don’t know what product is on your roof, the inspection identifies it and the report tells you what replacement options match.
Common Roof Inspection Problems We See in Napa Homes
- Failed 1990s clay tile underlayment in Silverado and Browns Valley. The original underlayment on homes built in the 1990s is now past its service life. Napa’s summer UV bakes the felt; winter rains then find every crack in the tile. We catch this before the ceiling stains appear.
- Corroded ridge vent screens and ember entry points. After the Glass Fire and Tubbs Fire, Napa County inspectors and insurers started demanding screened eave and ridge vents. Homes built before 2010 often have rusted-through screens, and hot embers don’t need a big hole. A pencil-sized gap is enough.
- Downspouts emptying onto open ground on acreage lots. Water ponds at the foundation, at the detached ADU slab, and around the shop. The next wet Napa winter finds the failed flashing and underlayment that nobody checked. We flag grading and drainage in every acreage inspection.
- Thermal camera misses by walk-the-roof inspectors. Napa tile roofs hide moisture in batten cavities where you can’t see or feel it. We’ve been called to Silverado-area estates where a standard inspection reported a clean roof, but our thermal imaging found trapped moisture and ember signatures the previous inspector never caught.
Pricing for Roof Inspection in Napa, CA
A standard single-family roof inspection in Napa runs $180 to $450. If your property is on acreage with a detached shop or ADU, expect $450 to $800. A full insurance-grade inspection with thermal imaging, ember-resistance documentation, and a formal written report on a Napa Valley winery estate or large tile roof runs $800 to $1,200.

FAQs About Roof Inspection in Napa
If your Napa property is outside city limits, roof repairs and replacements identified in an inspection go through Napa County permitting, not City of Napa permitting. That changes timelines, fees, and sometimes the required underlayment and venting specs. Inside Napa city limits, the City of Napa building department handles the permit. Brennan Roofing pulls permits for the work we do and passes the inspection the first time. Call (361) 320-9467 and we’ll tell you which path applies to your address.
Because the failure modes that matter in Napa, trapped moisture in tile batten cavities and hidden ember signatures after a red-flag event, are invisible to the naked eye. A walk-the-roof inspection misses them. Our thermal cameras find heat differentials under tile and decking that point to active moisture or smoldering embers. In a wildfire-prone county like Napa, that’s not an upsell; it’s the inspection. Call (361) 320-9467 to schedule one.
Yes. Every structure on the property is walked and documented: main house, detached shop, ADU, and covered outbuildings. Napa’s acreage lots have failing flashing and drainage issues around outbuildings that city-lot inspectors never deal with. You get one report covering all of it, priced by the full scope, not just the main roof square count.
We verify screened eave and ridge vents, metal drip edge, Class A cap sheets, and bird stops at the tile runs. We check that every vent screen is intact, not just present, and we document each item with photos and notes. If your insurer wants ember-resistant detailing after the Glass Fire mandates, our report gives them what they need without a re-inspection. Call (361) 320-9467 if you’re not sure what your policy requires.
Yes. Winery estate roofs are usually large tile roofs with steep access, long equipment haul paths from the road, and sometimes restricted entry during crush or event hours. We scope those before quoting. The inspection price for a Napa Valley winery estate typically runs $800 to $1,200. You get the number in writing before we set foot on the roof. Call (361) 320-9467 for an exact quote on your estate.
