We know San Leandro roofs because we work on them every week. From the 1950s tracts off Bancroft Avenue to the hillside homes in Bay-O-Vista, the housing here has its own character and its own failure patterns. A roof inspection isn’t a drive-by glance. It’s a systematic check of shingles, flashing, decking, ventilation, and drainage, done by someone who knows what fog-belt moisture does to a low-slope roof over twenty years.
Why Brennan Roofing Is San Leandro’s Preferred Roof Inspection Company
We operate under what we call the Garrison Standard. It means the price goes on paper before any work starts, the technician who shows up is background-checked and in uniform, and every job carries a 365-Day Done Right Promise in writing. That’s not marketing language. It’s how we run every inspection in San Leandro, whether it’s a 900-square-foot bungalow near Washington Manor or a larger custom home in Estudillo Estates.
San Leandro homeowners call us because we answer the phone with a live person, not a voicemail tree. When you call (361) 320-9467, a real person picks up, day or night. We schedule inspections around your availability, and our technician arrives inside the promised window. No ghosting. No “we’ll be there sometime Thursday.”
Our reputation in San Leandro is built on the inspections where we found things other roofers missed. Travis Oakley, who leads our team, has spent years working on East Bay roofs, and he trains every technician to inspect the way he would on his own home: methodically, with a moisture meter in hand, checking the places where problems hide.
Roof Inspection Companies in San Leandro
Roof inspection companies in San Leandro range from solo operators who walk the roof with a camera to established firms like Brennan Roofing that document findings with moisture readings, attic photos, and written repair scopes. When you’re choosing who to trust, the question isn’t just price. It’s whether the inspector will actually find what’s wrong before it becomes a five-figure problem.
For a standard residential Roof Inspection, expect to pay $195 to $425 in San Leandro. That includes a full visual inspection of the roof surface, flashing points, gutters, and attic ventilation, plus a written report with photos and a recommended repair plan with line-item pricing. We don’t do verbal-only reports. You get everything on paper.
Residential Inspection Walkthrough
On a typical San Leandro ranch, we start at the ridge and work down. We check shingle condition, look for granule loss, probe suspect areas for soft decking, and photograph every issue. Then we go into the attic to check for daylight penetration, moisture staining, and whether the original skip sheathing is holding up.
Inspection Reports That Mean Something
Your report includes photos of every problem area, moisture readings where relevant, and a plain-English explanation of what needs attention now versus what can wait. If we recommend repairs, you get written line-item pricing before you decide anything. No pressure. No door-knocker tactics.
Commercial Roof Inspection in San Leandro
Commercial roof inspection in San Leandro covers low-slope membrane roofs, built-up roofing, and metal systems on warehouses and retail buildings along corridors like Alvarado Street and East 14th Street. The stakes are higher with commercial roofs because a leak can shut down a business, damage inventory, or create liability issues with tenants.
A commercial inspection in San Leandro typically runs $450 to $1,200 depending on roof size and complexity. We inspect membrane seams, flashing terminations, drain systems, and ponding areas. You get a written report with photos, a condition assessment, and a prioritized repair plan with pricing. If you need documentation for a property sale or insurance renewal, we provide that too.
Multi-Tenant and Warehouse Roofs
Buildings with multiple roof penetrations, HVAC units, and older membrane systems need careful attention. We map every penetration, check for failed sealant, and test seam integrity. In San Leandro’s fog belt, ponding water tends to linger on flat commercial roofs, so we pay special attention to drainage and low spots.
Preventive Maintenance Assessments
If you own or manage a commercial building in San Leandro, an annual inspection catches small problems before they become roof replacements. We provide a written maintenance schedule and will handle repairs under the same 365-Day Done Right Promise we offer residential customers.
Trusted Brands We Service in San Leandro
We install and service roofing materials from GAF, Atlas, and Tamko, among other leading manufacturers. That matters because San Leandro’s mix of mid-century tract homes and newer builds means no single product line fits every roof. If your home has a GAF Timberline shingle roof, we know its expected lifespan and common failure modes. If you have an Atlas system, we understand how those shingles perform in fog-belt moisture conditions. We stock commonly needed components locally, so repairs don’t wait on parts shipped from Sacramento.
Common Roof Inspection Problems We See in San Leandro Homes
- Rotted skip sheathing under original shingles. Many San Leandro tract homes still have 1×6 skip sheathing from the 1950s and 60s. When fog-belt moisture gets under the shingles, that sheathing rots from the top down. An inspection that doesn’t probe below the shingle line misses it entirely.
- Moss and algae on north-facing slopes. The marine air that pushes through the San Leandro gap keeps north-facing roof planes damp. Moss holds water against shingles, shortens their life, and hides granule loss. We note its extent and recommend remediation before it forces a premature reroof.
- Inadequate attic ventilation. Original tract homes here often have minimal venting. Trapped heat and moisture degrade decking and shingles from underneath. We check soffit vents, ridge vents, and airflow patterns during every inspection.
- Loose flashing at roof-to-wall connections. The Hayward Fault isn’t hypothetical in San Leandro. Roof-to-wall flashing that’s corroded or loosely fastened is more likely to separate during seismic movement. We check these connections and recommend flexible flashing where appropriate.
Pricing for Roof Inspection in San Leandro, CA
A standard residential roof inspection in San Leandro runs $195 to $425. Homes with steep pitches, multiple roof levels, or extensive moss coverage may land at the higher end. Commercial inspections start around $450 and go up with building size. If we find damage during the inspection, any repair costs are quoted separately in writing before you approve anything. We don’t surprise you with a bill after the fact. Every price goes on paper first. Call (361) 320-9467 to schedule your inspection, and we’ll confirm your exact price when we book the appointment.
In Bay-O-Vista, we inspected a 1958 ranch with a low-pitch roof and found moss intrusion and rotted skip sheathing under the north-facing slope. Our tech used a moisture meter to map the damage, then replaced the failed decking, installed ice and water shield in the valleys, and added a ridge vent to improve attic ventilation. The homeowner avoided a full tear-off surprise because we priced and approved the decking repair in writing before we started.
That’s how we handle every inspection in San Leandro. San Leandro homeowners get a straight answer about what their roof actually needs, what it costs, and what can wait. No scare tactics. No inflated estimates. Just a written report you can use to make a sound decision.

FAQs About Roof Inspection in San Leandro
An inspection on a 1950s tract home includes a full visual check of shingles, flashing, gutters, and ventilation, plus attic access to examine the skip sheathing from underneath. We probe suspect areas for soft decking and use a moisture meter to confirm rot. You get photos of everything. If the sheathing is failing, we’ll show you and give you a written price for replacement. Call (361) 320-9467 for an exact quote.
Fog-belt moisture means we’re more likely to find moss, algae, and moisture-related decking rot in San Leandro than in drier cities like Hayward or Fremont. North-facing slopes are the usual suspects. We check for these conditions specifically because they accelerate shingle failure and can hide structural damage. If you’ve noticed moss or dark streaks on your roof, call (361) 320-9467, and we’ll take a look.
We check roof-to-wall connections, flashing fastening, and any signs of movement or separation, particularly along the roof perimeter. The Hayward Fault runs through the East Bay, and loose connections are more likely to fail during seismic activity. We’ll note any vulnerabilities in your written report. Call (361) 320-9467 to schedule.
