A roof inspection in El Sobrante typically runs $180 – $340 for a standard single-family home, with most inspections completed in under two hours.

Call (341) 208-3988 to schedule yours; you’ll get a live person on the phone, not a voicemail queue.
We know El Sobrante roofs. We know the 1960s ranch-style homes off Appian Way with original shake underlayment. We know the flat-roofed commercial buildings along San Pablo Dam Road that hold ponding water after a winter storm. We know how the fog off the Berkeley Hills settles into the El Sobrante Valley and keeps north-facing slopes damp long enough for moss to take hold. A roof inspection here isn’t a drive-by glance. It’s a methodical, documented walk of every plane, penetration, valley, and edge, because the microclimate in El Sobrante does things to a roof that a generic inspection anywhere else won’t catch.

Why Brennan Roofing Co Riverside Is El Sobrante’s Preferred Roof Inspection Company
El Sobrante homeowners have a specific set of roof problems, and you need an inspector who knows what those problems look like before the leak opens your ceiling. We’re part of the Garrison Partners family, founded in 2000, and every location operates under the same Garrison Standard. That means the inspection you get on a hillside home off Hillcrest Road is conducted to the same written checklist as every other job we run. No shortcuts because a roof is hard to access. No assumptions because a neighborhood is older.
Travis Oakley leads our crews, and the discipline starts with him. When our technicians arrive in El Sobrante, they’re background-checked and in uniform. You know who’s on your roof. The report you receive is detailed enough to hand to an insurance adjuster or keep in a file for when you sell the home. We work the way a roofer should: written findings, written prices, and a 365-Day Done Right Promise on any repair we perform. If the repair fails within a year, we come back and fix it at no charge. In writing, not a verbal promise.
Our Roof Inspection team covers the whole valley, from the older subdivisions near De Anza High School to the newer builds up toward the hills. Call (341) 208-3988 and a live person answers. That matters when you’ve got water staining a bedroom ceiling and you need someone to actually pick up the phone.
Styles & brands we work with






Commercial Roof Inspection in El Sobrante
Commercial Roof Inspection in El Sobrante means working flat and low-slope roofs along San Pablo Dam Road where ponding water, failed flashing at penetrations, and wind-blown eucalyptus debris are the constant enemies. A standard shingle-only inspection misses these entirely. We walk every low-slope section, check drain flow, probe membrane seams, and document every penetration. For a small commercial building under 5,000 square feet, expect $400 – $650 for a full inspection with a written report and repair recommendations with line-item pricing.
Flat-Roof Failure Points We Document
On El Sobrante commercial buildings, we focus on the spots that actually fail: scuppers and drains clogged with eucalyptus leaf litter, HVAC curbs where the flashing has pulled loose, and seams in older modified bitumen or TPO that have begun to crack from sun and temperature swings. We identify ponding areas that hold water longer than 48 hours, because standing water on a low-slope roof is how you get premature membrane failure and interior leaks.
What You Get in the Report
Every commercial inspection includes photos with time and location stamps, a list of active deficiencies and their severity, and a written repair priority list with line-item pricing. If you’re buying or selling a commercial property in El Sobrante, this report holds up in the transaction and with your insurance carrier.
Roof Inspection Services in El Sobrante
Roof Inspection Services in El Sobrante start at $180 for a standard single-family home inspection and go up to $340 when the roof is steep, multi-level, or shows signs of previous patch work that requires closer examination. The inspection covers flashings, decking condition where accessible, shingle adhesion and granule loss, drip edge, underlayment at edges and valleys, and any signs of moss or rot on shaded slopes. Every inspection ends with a written report and a written repair price if there’s work to be done.
Buyer and Seller Inspections
If you’re in escrow on a home in El Sobrante, a roof inspection before you sign is cheap insurance. We document the actual remaining life of the roof, not a guess, and give you a line-item estimate for whatever the seller discloses or doesn’t. That number on paper is what you take to the negotiating table.

Maintenance Inspections for Older Homes
Most El Sobrante homes were built between the 1950s and 1980s. That means a lot of composition shingle roofs are in their final years of service, and a significant number still have original shake underlayment underneath. An annual maintenance inspection catches loose ridge caps, lifted starter strips, and eucalyptus-packed valleys before they become leaks.

Trusted Brands We Service in El Sobrante
We service and install roofing materials from manufacturer lines including IKO, Atlas, and Tamko, and we keep common accessories in local stock for fast turnaround on El Sobrante jobs. Whether your roof has original Atlas shingles from the 1990s, an IKO architectural line, or a Tamko starter and ridge system, our crew knows the product specifications and warranty requirements. When an inspection finds damage limited to one section, we can often match the existing material closely enough that the repair disappears into the roof. You choose the material based on your budget and the home’s exposure, and we’ll explain the real differences between each line in plain terms.
Common Roof Inspection Problems We See in El Sobrante Homes
- Eucalyptus debris packed into valleys and eaves. The dense groves along the creek corridors drop leaf litter that traps moisture against shingles and decking. Left in place, this is how wood rot starts, especially on shaded north-facing slopes where moss grows on the damp debris.
- Wind-lifted shingles at ridge vents and starter strips. The gusty winds that channel through the San Pablo Creek corridor lift shingles at the edges first. A visual inspection from the ground misses these; you have to walk the roof and actually lift the shingles to check sealant adhesion.
- Original shake underlayment failing under composition shingles. Many 1950s and 1960s houses in the El Sobrante Valley had cedar shake roofs originally, and when those were recovered, the old underlayment stayed. Now it’s decades old and failing out of sight. We find this on homes near the hills and off Appian Way all the time.
- Missing or damaged drip edge. Older splits and ranch-style homes often have no drip edge or a rotted one, and that lets water wick back into the fascia and decking at the eaves. On El Sobrante’s older homes, this is one of the most common deficiencies we document.

AfterPricing for Roof Inspection in El Sobrante, CA
A standard roof inspection in El Sobrante runs $180 – $340. That’s the number on paper before we arrive, and it doesn’t move at the door. The variables are roof size, the number of stories, the pitch, and whether we need to access multiple roof surfaces. A single-story ranch with a simple gable roof is on the lower end. A split-level with multiple ridges and a low-slope section over the addition is on the higher end. Commercial flat-roof inspections run $400 – $650. If the inspection uncovers repairs, you’ll get a written line-item price for that work before any of it starts. Call (341) 208-3988 and we’ll schedule the inspection at a time that works for you.

FAQs About Roof Inspection in El Sobrante
Eucalyptus leaf litter is the difference. In El Sobrante, the dense groves drop debris that packs into valleys and eaves, trapping moisture and accelerating wood rot. An inspection here must include physically clearing debris from valleys and lifting shingles near eucalyptus overhangs to check the decking underneath. In Richmond, where the housing is flatter and less tree-covered, an inspection can get away with more visual checks. In El Sobrante, skipping the debris check means missing rot that’s already started. Call (341) 208-3988 if you suspect eucalyptus damage.
The inspection should verify whether the original shake underlayment is still present, what condition it’s in, and whether the decking beneath it has started to rot. If the shake underlayment is failing, it can trap moisture against the decking and rot the wood from the top down. Our crew probes soft spots, checks for granule loss on the overlying shingles, and documents any evidence that the underlayment has reached the end of its useful life. That finding changes the repair scope, which is why we put it in writing with a line-item price before any work starts.
A standard shingle inspection misses ponding water, failed flashing at penetrations, and seam deterioration on the membrane. El Sobrante commercial buildings along San Pablo Dam Road regularly accumulate eucalyptus debris in drains and scuppers, which causes ponding that breaks down the membrane over time. Our commercial inspection documents every penetration, checks drain flow, and notes any ponding areas that hold water for more than 48 hours. These are the conditions that turn into interior leaks if left unaddressed. For an exact price on a commercial inspection along San Pablo Dam Road, call (341) 208-3988.
The wind through the San Pablo Creek corridor hits roofs from the side, not just straight on. That means lifted shingles tend to start at ridge vents, starter strips, and valley intersections, not in the middle of the field. An inspector needs to physically lift shingles at those edges and check the sealant strips. Visual inspection from the ground misses it. After any storm event in the corridor, we recommend checking the valleys and starter strip first.
Opening up an older El Sobrante roof often triggers code-mandated upgrades like ice and water shield at the eaves, improved ventilation to current ratios, and replacement of any decking that doesn’t meet minimum thickness. A simple inspection quote doesn’t include these because the inspector hasn’t opened the roof yet. We handle it by writing a repair allowance into the quote for exactly these unknowns. If we open the roof and find the decking is rotted, you approve the revised figure in writing before we replace a single board. No surprises at the end of the job. Call (341) 208-3988 and we’ll explain how the allowance works on your specific roof.
