Fast, Reliable Roof Inspection Across San Leandro
A roof inspection in San Leandro for a typical mid-century ranch or bungalow runs $180 – $340, and most inspections are scheduled within 48 hours of your call. We inspect the whole roof, not just the obvious spots: shingles, low-slope sections, flashing, drip edge, penetrations, and the transitions between pitched and flat areas that give San Leandro homes so much trouble. Call (831) 318-8819 to schedule yours.

We know San Leandro roofs because we walk them every week. From the Davis Tract to Washington Manor to the hillside streets above Estudillo Avenue, the housing stock here has a personality all its own. Single-story and split-level homes built between 1940 and 1970, often with composition shingle pitched roofs that run into flat or low-slope sections over additions, garages, or sunrooms. That mixed-roof configuration changes what an inspection has to catch, and it’s exactly why a generic walkaround misses what a San Leandro roof actually needs.
Why Brennan Roofing Co San Francisco Is San Leandro’s Preferred Roof Inspection Company
We operate under The Garrison Standard, which means the price goes on paper before any work starts and it does not move at the door. That matters in San Leandro, where hidden conditions like original shake under later shingle layers are common and change the scope of a job. You get a written scope with real numbers, not a vague promise.
Every technician who arrives at a San Leandro home is background-checked and in uniform. You know exactly who is on your roof, and you know when they’re coming. We answer phones with a live person around the clock. No voicemail, no callback queue.
Led by Travis Oakley, our crews serve San Leandro directly from the San Francisco Bay Area office. We’ve inspected hundreds of mid-century homes here, and we’ve learned what to look for on the mixed pitched and flat profiles that dominate the city’s neighborhoods.

Roof Estimate in San Leandro
A Roof Estimate in San Leandro is the written price you get before any roofing work begins, and it’s the only way we do business. For an inspection-focused estimate on a typical San Leandro home, expect $180 – $340 depending on roof size, access, and whether you need a full written condition report for a real estate transaction or insurance claim.
What The Estimate Covers
We document every roof surface: shingle condition, granular loss, cracking, curling, and missing tabs. We check valleys, penetrations, and every drip edge. On San Leandro homes, we pay special attention to the transition points where a pitched section meets a flat addition. That’s where wind-driven rain from the Bay gets in.
Written, Fixed, And Before Work Starts
The Garrison Standard means the number on that estimate is the number you’ll pay. We put it in writing before any work begins, and it does not move at the door. If we find something during the inspection that changes the scope, we price it, we show you, and we get your written approval before touching it. No change orders from nowhere.
Free Roof Inspection in San Leandro
A Free Roof Inspection in San Leandro is available for homeowners who suspect a problem or are preparing to sell and need to know what a buyer’s inspector will flag. There’s no charge for the visit, and you’ll get a plain-English summary of what we found, what it means, and what it costs to fix. Call (831) 318-8819 and ask for the free inspection.
What We Check
We inspect shingles, underlayment, decking, flashing, drip edge, and ventilation. On San Leandro homes, we also check low-slope and flat sections for ponding water, which shortens membrane life and leads to winter leaks. We document everything with photos so you can see exactly what we see.

When San Leandro Homeowners Schedule This
Most calls come before the rainy season starts in November, or after a windy stretch blows shingles loose along the East Bay hills. Others call because they’re selling and want to avoid surprises at escrow. Whatever the reason, you’ll leave the inspection knowing the condition of your roof and the honest cost to fix it.

We install and inspect roofs built with GAF, CertainTeed, and Owens Corning materials, and we stock common replacement components for San Leandro homes so repairs don’t stall waiting on parts. If your roof was built with IKO or another manufacturer, we’ll tell you plainly what we found and what compatible materials make sense. The point is a roof you can count on, not a brand pitch. We source from leading manufacturer lines and explain the real options so you choose with confidence, and the written estimate reflects exactly what we’ll install.

AfterCommon Roof Inspection Problems We See in San Leandro Homes
- Hidden original shake under composition shingles. Many 1950s homes in the Davis Tract and similar subdivisions still carry their original wood shake beneath one or two later layers of composition shingle. That adds weight your framing was never sized for and doubles or triples disposal cost on a tear-off. An inspection that misses this gives you a quote that won’t survive the first day of work.
- Ponding water on low-slope sections. Flat roofs over additions, garages, and sunrooms hold water after rain. San Leandro’s wet winters turn that ponding into membrane breakdown, and leaks usually show up inside the house months after the roof itself gave up. We measure low spots and document drainage so the fix is right, not just a patch.
- Flashing failures at pitched-to-flat transitions. Wind-driven rain from the Bay pushes water into the seams where shingles meet membrane. Deteriorated flashing and missing drip edge at those transitions is the single most common leak source we find on San Leandro mid-century homes. We check every transition, not just the ones that look wet.
- Decking rot from decades of slow moisture. Original plywood decking on 1950s and 1960s homes often has soft spots hidden under shingles that still look fine from the ground. We probe for delamination and document every soft section so the repair quote accounts for decking replacement instead of discovering it mid-job.
Pricing for Roof Inspection in San Leandro, CA

FAQs About Roof Inspection in San Leandro
We inspect both roof types as separate systems, because they fail differently. Pitched shingle sections get checked for granular loss, curling, cracking, and wind damage. Flat or low-slope sections get checked for ponding water, membrane wear, blistering, and seam separation. We also inspect every transition between the two, because that’s where wind-driven rain from the Bay intrudes most often on San Leandro homes. Call (831) 318-8819 to schedule an inspection that covers both.
We document it, measure it, and add the tear-off weight and disposal volume to your written scope. You won’t find out on the first day of demo. Original shake under later shingle layers is common in San Leandro’s 1950s-era tracts, and it changes both the labor and the disposal cost. You’ll get a written estimate that includes removing every layer down to the decking, inspecting the framing under the added weight, and rebuilding to current code. Call (831) 318-8819 for an exact quote.
No. You don’t need to be home for the exterior inspection itself. We walk the roof, check the attic access if it’s available, document everything, and leave a written summary at your door or email it the same day. Many San Leandro homeowners prefer to be present so we can point out issues as we find them, but the written report stands on its own either way.
Yes. Ponding water is a specific failure mode on San Leandro’s flat and low-slope roof sections, and we check for it on every inspection. We look for low spots, measure standing water after rain, and document membrane wear in areas that hold water longest. Ponding shortens membrane life and leads to leaks during the wet winter months, so catching it early saves you a full replacement later. Call (831) 318-8819 and we’ll check yours.
Most single-story San Leandro ranch homes take 60 to 90 minutes to inspect properly. Larger split-levels or homes with multiple additions and complex roof transitions can take up to two hours. We don’t rush, and we don’t cut corners. You’ll get a thorough report with photos, and the written scope of any recommended work comes included. Estimates are free.
If your roof hasn’t been looked at in years, or if you’re planning to sell before the next rainy season, call Brennan Roofing Co San Francisco at (831) 318-8819. We’ll schedule an inspection, put everything in writing, and stand behind our work with the 365-Day Done Right Promise.
