AfterRoofers in Martinez, CA
Roofing in Martinez is a study in two climates. Homes near downtown and the waterfront bake under a rain-shadowed sun that ages asphalt shingles 2 – 3 years faster than the foggy hills, while houses up on the ridges above the John Muir site take 40+ mph gusts off the Carquinez Strait that rip ridge caps loose every winter. We quote every Martinez job by starting with which microclimate the house sits in, because a roof that works downtown will not necessarily hold up on the hill. If you need a roofing crew that shows up on time and backs the work with a written guarantee, call Brennan Roofing at (361) 320-9467.
Why Martinez Homes Are Different
Martinez has two housing stocks that fail in two different ways. The early-1900s Victorians and Craftsmans downtown and along Alhambra Creek often still have original skip-sheathing under multiple roof layers. When we tear off those roofs, we find dry-rotted fascia and attic ventilation that was never adequate in the first place. Those homes need decking repair and ventilation upgrades before new shingles go on, not just a re-roof.
The 1950s – 70s ranch tracts in the Alhambra Valley and the 1980s – 90s hillside subdivisions off Reliez Valley Road and Vine Hill are a different story. Many of those hillside homes still carry original 20-year shingles that hit end-of-life by the mid-2010s. After the first big atmospheric river of the season, those roofs fail in patches, especially on planes facing the Carquinez Strait wind tunnel. The fix is rarely a full replacement – it is targeted repair on the windward slopes plus flashing work at the valleys and eaves where wind-driven rain finds its way in.
Our Main Martinez Services
Homeowners in Martinez call us most often for full replacement work on older homes and for repairs after the rainy season. Each service has its own page with pricing, process, and the Martinez-specific details.
Roofing Company in Martinez
A full reroof in Martinez almost always starts with what we find under the old shingles. On the historic homes downtown, that means skip-sheathing, sometimes two or three layers of shingles, and flashing that has been patched for decades. On the hillside homes, it means original 20-year shingles that have delaminated and decking that has taken years of wind-driven rain. Our Roofing Company in Martinez page covers tear-off, decking replacement, underlayment, drip edge, flashing, and the shingle options we install from GAF, CertainTeed, and Owens Corning.
Roof Repair in Martinez
Most Martinez repair calls come in the week after a wind event. We find lifted or missing shingles on windward roof planes, ridge caps pulled loose on hillside homes, and leaks at valley flashing where the rain-shadow storms drove water sideways. Repairs on older downtown homes sometimes turn into two-part jobs when we open the roof and find rotted decking or failed underlayment. Our Roof Repair in Martinez page explains what a repair quote includes and how our 365-Day Done Right Promise applies.
Roof Inspection in Martinez
Given the split climate in Martinez, inspections are the most undervalued roofing service here. Downtown homes need a UV and granule-loss check on south and west-facing slopes every few years. Hillside homes need a wind-damage walkthrough after every storm season. An Roof Inspection in Martinez gives you a written report on what we find, what needs work now, and what can wait. We do not charge for the inspection when it leads to a repair or replacement quote.

What pushes a Martinez quote higher than the table shows is what is underneath: multiple shingle layers on the old downtown homes, rotted decking on hillside homes, or ventilation work that has been overdue for years. The price we put in writing before any work starts is the price you pay – it does not move at the door. No change orders unless you ask for more work, and you approve the number on paper first.
