Why Brennan Roofing Co San Francisco Is Martinez’s Preferred Roof Inspection Company
Martinez homeowners call us because we treat a roof inspection like a diagnostic, not a sales pitch. We’re not there to scare you into a replacement. We’re there to document what’s failing, what’s marginal, and what’s solid, so you can make a decision with facts in front of you. The price goes on paper before we set a ladder against your fascia. It doesn’t move at the door. That’s the Garrison Standard, and it’s the same on a 1920s Craftsman near downtown as it is on a 1960s ranch off Center Avenue.
Travis Oakley runs our Martinez inspection work. The crew shows up in uniform, background-checked, and inside the window we committed to. If we recommend Roof Repair in Martinez and it fails within a year, we come back and fix it at no charge. In writing, for one full year. That’s our 365-Day Done Right Promise, and it applies to every inspection-driven repair we perform in Martinez.
We answer the phone with a live person around the clock. No voicemail tree. No “leave a message and we’ll get back to you.” If you call at 7 a.m. on a Tuesday or 10 p.m. on a Saturday, a human picks up. That matters when you’ve got water coming through the kitchen ceiling and you need to know whether it’s an emergency or a slow leak.
Our Roof Inspection in Martinez work reflects more than two decades of the Garrison Partners family operating to the same standard. Each location is independent, but the process is uniform: written pricing, disciplined crews, documentation you can file with a permit application or hand to a lender.
Styles & brands we work with
Commercial Roof Inspection in Martinez
Commercial Roof Inspection in Martinez is a different animal from residential work, and we handle it accordingly. Low-slope roofs on retail buildings along Alhambra Avenue, office buildings near the Court Street corridor, and industrial spaces on the city’s eastern edge all need drainage mapping, membrane condition evaluation, and penetration seal checks. A commercial inspection in Martinez typically runs $450 – $900 depending on square footage and roof type. You’ll get a written report with photographs, a moisture map if we use infrared scanning, and a line-item list of any deficiencies we find, each with a repair priority.
Flat and Low-Slope Membrane Evaluation
Low-slope commercial roofs fail at the seams and penetrations before anywhere else. We walk the entire field of the roof, check lap integrity on TPO or modified bitumen membranes, and document ponding water locations. Ponding is common on older Martinez commercial buildings with settled roof decks, and it’s the single fastest way to shorten a membrane’s lifespan.
Documentation for Buyers and Lenders
If you’re buying a commercial property in Martinez, your lender may require a roof condition report as part of the financing package. We write reports lenders accept: age assessment, remaining useful life, repair cost estimates, and replacement timeline projections. You’ll have the documentation in hand, not a vague verbal summary.
Roof Inspection Services in Martinez
Roof Inspection Services in Martinez cover a range of needs: pre-purchase inspections, storm damage documentation for insurance claims, annual maintenance checks, and post-installation verification. A standard residential inspection covers the roof surface, flashing, valleys, penetrations, gutters, and attic ventilation. On older Martinez homes, we go further: we look for hidden deck rot under original shake layers, check whether composition shingles were installed over cedar without proper underlayment, and evaluate whether the original nailing pattern meets current high-wind standards.
We inspect in the attic too. That’s where the real story usually is. Staining on the underside of the decking, daylight at the ridge, missing insulation baffles, mold on the sheathing, and absent ridge vents on 1950s – 1970s ranch homes all show up there before they show up as interior stains. An inspection that skips the attic misses half the diagnosis.
Residential roof inspections in Martinez run $225 – $425. The variance comes down to roof complexity, age, accessibility, and whether we need to pull back a section of shingle to check decking condition on a suspect area. You’ll know the exact price before we start. Free estimates are not a vague promise; we write the number down and hand it to you before any work begins.
Pre-Purchase Inspections
Buying a home in Martinez? A pre-purchase roof inspection tells you whether you’re budgeting for five years of life or fifteen. We give you an honest remaining-useful-life estimate, not a sales pitch. When the inspection is done, you’ll know whether the roof needs patching, partial replacement, or full tear-off, and what each option costs.
Storm and Wind Damage Assessment
Wind coming off the Carquinez Strait hits Martinez roofs hard, especially in Alhambra Valley and on ridge lines above Highway 4. After a big storm, we document lifted shingles, broken seals, missing granules, and shifted flashing. The report includes photos and measurements suitable for filing an insurance claim, along with a repair estimate in writing.

Common Roof Inspection Problems We See in Martinez Homes
- Hidden deck rot under original shake. Victorian and Craftsman homes near downtown often have cedar shake roofs that look serviceable from the ground but hide rotted decking underneath. We probe suspect areas and document what can’t be seen from the curb. Skipping this check means buying a new roof layer that’s already compromised.
- Inadequate nailing patterns in wind-exposed areas. Homes in Alhambra Valley and other ridge-top locations near the Carquinez Strait get hit with gusts that test every nail. Shingles nailed too high or too shallow start lifting within a few seasons. Our inspection checks nailing patterns against current high-wind standards, not just whether the shingles look fine from the ground.
- Absent ridge venting on east-side ranch homes. 1950s – 1970s tract homes on Martinez’s east side often have no ridge vents and minimal attic ventilation. The result is trapped heat and moisture that curls shingles from the underside and rots decking from above. We catch this in the attic before it becomes a $8,000 – $14,000 re-roof.
- Improper flashing at chimneys and skylights. Older Martinez homes have had decades of repairs, and not all of them were done right. We routinely find caulk-over-flashing jobs, missing step flashing, and kickout flashing that doesn’t direct water away from walls. Each one is a slow leak waiting to become visible damage.

FAQs About Roof Inspection in Martinez
Yes, a historic-district roof inspection in downtown Martinez is more detailed because the repair standards are stricter and the materials are older. On a Victorian or Craftsman home, we document the specific type of cedar shake or shingle, the flashing profile, the nailing pattern, and the condition of the underlying decking in a way that matches what the city’s historic preservation guidelines require for permit applications. On a 1960s ranch, the focus is different: ventilation, composition shingle condition, and decking rot. Same day, same crew, different checklist. Call (831) 318-8819 if you need an inspection that will hold up to historic-district review.
A roof inspection on a Martinez home near the Carquinez Strait should catch inadequate nailing patterns, lifted shingle edges, broken seal strips, and flashing that has been torqued loose by repeated gusts. Homes in Alhambra Valley and along ridge lines above the strait get hit with concentrated wind that doesn’t show up in most inspection templates. We check nail placement against the shingle manufacturer’s high-wind installation spec and document any deviations in the report. If there’s a problem, we’ll quote the fix in writing and back it with our one-year guarantee.
Working on a tight Martinez lot changes how we access the roof, where we stage ladders, and how carefully we document the conditions. Many older Martinez homes have narrow side yards, shared driveways, and steep roof pitches that make ladder placement a real calculation. We inspect from the roof surface, not just from the ground, and we map access constraints into our report so any future repair crew knows exactly what they’re walking into. We also keep debris and equipment staged tight to the house so we don’t block a neighbor’s driveway or protrude into a shared walkway. If access is genuinely restrictive, we’ll tell you before we start and include it in the written price.
Yes, an attic and surface inspection can tell whether your 1960s Martinez ranch home needs new decking or just new shingles. We probe the decking in suspect areas, measure moisture content in the attic, and look for delamination or rot around penetrations and at the eaves. If the decking is sound, you’ll see that in the report. If it’s failing in sections, we’ll map the exact areas and quote a repair that addresses only what needs replacing. That means you don’t pay for a full re-deck when three sheets of plywood would do the job.
Yes, a roof inspection before filing a permit for a roof replacement in a Martinez historic overlay district is strongly recommended, and in many cases required by city staff. The inspection documents existing materials, roof pitch, flashing details, and any non-historic alterations from previous decades. That documentation goes directly into your permit application, and it gives the preservation staff what they need to evaluate your proposed work. We’ve done enough Martinez historic-district inspections to know what the planning department looks for. We’ll write the report so you can file with confidence. Call (831) 318-8819 to schedule one.
