Fast, Reliable Roof Inspection Across Dixon
A roof inspection in Dixon, CA typically costs between $150 and $350 for a standard residential roof, with the final number tied to roof complexity, access, and what we find once we’re up there. Most inspections run two hours or less, and you get a written report with photos plus a plain-English summary of what’s failing, what can wait, and what needs attention before the next storm. We dispatch crews to Dixon from our Bay Area office, and we answer the phone with a live person every time you call (361) 320-9467.
Dixon roofs get hit harder than most Sacramento Valley towns. This stretch of the I-80 corridor sits squarely in what local roofers call “hail alley” – that narrow band where late-spring storms drop golf-ball-sized hail without much warning. Add in the July heat baking east-side attics with no ridge vents, and you have a roofing market where inspections aren’t optional. They’re the difference between a $200 fix now and a $2,000 decking repair after the first winter rain. Travis Oakley started Brennan Roofing with a simple rule: the price goes on paper before any work starts, and it doesn’t move at the door. Our inspectors follow the same rule when they walk your roof.
Why Brennan Roofing Is Dixon’s Preferred Roof Inspection Company
Dixon homeowners don’t want a roofer who drives in from out of town, glances at the roof from the curb, and hands over a number pulled from thin air. They want someone who understands what a 1920s Victorian near downtown requires versus a 1995 tract home out by the high school. Our inspectors know the difference because they’ve walked both, dozens of times. The downtown Victorians need a careful eye on fire-rated assemblies and party-wall flashing. The east-side subdivisions need someone who’ll actually get into the attic and measure soffit intake – because half the homes out there have intake at half the code minimum, and the shingles are paying for it.
We’re an independently owned member of the Garrison Partners family, founded in 2000, and we operate under The Garrison Standard: background-checked, uniformed technicians who show up inside the promised window, a written price before any work starts, and a 365-Day Done Right Promise on every job. That promise is in writing and covers every inspection finding we act on for a full year. If a repair we made fails inside twelve months, we come back free. No re-quote, no argument, no charge.
Commercial Roof Inspection in Dixon
Commercial Roof Inspection in Dixon differs from a residential walk-through in one big way: the stakes are commercial. A leak over a retail space, a restaurant, or a warehouse isn’t a nuisance – it’s inventory damage, lost business hours, and a fire-safety concern if water reaches electrical. Our commercial inspectors focus on the exact failure points Dixon’s commercial stock is known for: low-slope membrane seams on 1980s retail strip buildings along the I-80 frontage, clogged drains and scuppers on flat warehouse roofs, and aging parapet flashing on the downtown storefronts that sit close enough to neighboring buildings to trigger fire-rating code requirements.
We inspect membrane condition, seam integrity, drainage, penetration flashing, and rooftop equipment curbs. We photograph everything, log it in a written report, and price any needed repair as a line item – before you sign anything and before material gets ordered.
Flat Roof and Storm Drainage Checks
Low-slope commercial roofs in Dixon carry water longer than residential pitched roofs, and Dixon’s spring thunderstorms dump rain fast. We check drainage paths, test for ponding, and walk the perimeter flashing where most leaks start.
Fire-Rating and Party-Wall Review
Downtown Dixon storefronts share walls. That means code requires specific fire-rated assemblies at the roof-to-wall intersections, and a missed gap there can turn into a fire marshal stop-work order after a permit is pulled. We check it on every commercial inspection.
Roof Inspection Services in Dixon
Roof Inspection Services in Dixon cover the full residential spectrum: pre-purchase inspections for homebuyers, post-storm assessments after the hail months, annual maintenance checks, and the inspection that happens before we quote any repair or replacement. A standard residential inspection includes a full roof-surface walk, attic access where possible, flashing and penetration review, gutter and downspout assessment, and a written report with photos. We also check the attic ventilation math on every Dixon inspection – east-side subdivisions routinely fail this, and it’s the silent killer of 20-year composite shingles.
Homeowners in Dixon call us most often after a hailstorm rolls through, before buying an older home, or when they suspect a leak they can’t trace.
Post-Storm Hail Inspection
Dixon’s hail alley storms crack shingle mats, dent architectural shingles, and loosen flashing in ways that don’t leak until the first winter rain. We check every penetration, every valley, and every flashing point after a storm.

Pre-Purchase Roof Evaluation
Buying a home in Dixon? Older homes often carry multiple layers of asphalt over original wood shake, which changes loading, rot potential, and code compliance the moment you pull a permit. Our inspection tells you what you’re really buying before you close.

Trusted Brands We Service in Dixon
Our inspectors are trained on the roofing systems most common across Dixon, and that means knowing the materials by manufacturer. We routinely inspect and service roofs built with GAF, CertainTeed, and Atlas products, among others. We understand their installation requirements, their common failure modes, and how Dixon’s heat and hail affect each one differently. When an inspection turns up damage that calls for a repair, we stock common local components for fast turnaround, and we can explain your material options plainly so you can choose with confidence. You never have to guess whether the repair matches the original system.
Common Roof Inspection Problems We See in Dixon Homes
- Layered asphalt over original wood shake. Many downtown Dixon homes built before World War II still have original shake under two or three layers of asphalt. The weight alone is a structural concern, and the hidden decking is almost always compromised. A surface walk misses this entirely.
- Undersized attic ventilation on east-side subdivisions. These 1980s-2000s homes often have soffit intake at half the code minimum and no ridge vent. Summer attic temperatures cook the shingles from underneath, causing premature cracking and granule loss that looks like age but is really ventilation failure.
- Hail impact damage without visible leaks. A golf-ball impact can hairline-crack the fiberglass mat while the shingle face looks fine. The leak shows up in winter, months after the storm. Our post-storm inspections include a mat-level check, not just a visual observation from the ground.
- Party-wall flashing gaps in downtown storefronts and row homes. Closely spaced older structures often have improper or degraded flashing where roofs meet shared walls. That gap is a water entry point and a fire-rating violation once a permit gets pulled. We check it every time.

FAQs About Roof Inspection in Dixon
Yes. Dixon sits in a narrow spring-storm corridor where golf-ball-sized hail is common, and a standard visual walk misses the hairline mat cracks that later leak. We check every shingle’s impact resistance, every flashing point, and every penetration after storm season. Call (361) 320-9467 to schedule a post-storm inspection – we’ll give you the price in writing before we climb up.
Because many of these Victorians still carry original wood shake under two or three layers of asphalt, and building code limits the total number of roof layers allowed. Adding another layer isn’t legal, and the underlying decking is usually rotted from decades of trapped moisture. A tear-off is the only way to inspect and repair the decking properly. We’ll write every step as a line item with pricing before work starts.
We walk every shingle, check all penetrations and flashing, and – critically – we get into the attic to measure ventilation. Most east side homes have insufficient soffit intake and no ridge vent, which cooks shingles from below. We give you the attic math check in writing along with the roof condition report. Call (361) 320-9467 for an exact quote on your home.
We price it as an allowance in the original written scope, and if the surprise is bigger than the allowance, we stop, photograph it, write a change order with the exact price, and get your signature before we order a single piece of material. That’s how Travis Oakley built the company, and nothing happens on your roof without your approval on paper first. Call (361) 320-9467 and we’ll walk you through exactly how it works.
Yes, and the difference is fire-rating. Downtown storefronts sit close enough to neighboring buildings that code requires specific fire-rated roof assemblies and proper party-wall flashing. A residential inspection skips these; our commercial inspection includes them every time, along with membrane, drainage, and equipment curb checks. Call (361) 320-9467 to schedule a commercial inspection at your Dixon building.
