AfterFast, Reliable Roof Replacement Across Martinez
A full roof replacement in Martinez typically runs $11,000 to $19,000 for architectural asphalt shingles on a standard ranch or hillside tract home, with tear-off and decking repair included. Most jobs take four to seven working days once materials land, and the free estimate you get up front is the price we honor, in writing, before a single nail goes in. If you’re reading this because a previous roofer no-showed or changed the number at the door, you’re exactly who we built Tilehurst Roofing for. Call (945) 303-9821 and you’ll reach a live person who can walk you through what your Martinez roof actually needs.
Why Tilehurst Roofing Is Martinez’s Preferred Roof Replacement Company
We’re the residential roofing arm of the Kingswell family of companies, founded in 2000, and every Tilehurst location commits to the same thing: a written price before any work starts, a written guarantee on every repair, and a live person answering every call, 24/7. That last part matters in Martinez, because when a Diablo wind event tears a section of ridge cap loose on a Tuesday night, you shouldn’t have to leave a voicemail and hope for a call back by Thursday. You call, we answer.
We know Martinez because our crews work here constantly, from the Victorian and Craftsman homes near downtown to the ranch tracts climbing the hills south of Highway 4. We’ve torn off original wood shake on Ferry Street, replaced failed built-up gravel roofs in Virginia Hills, and re-decked sun-baked composition shingle roofs off Alhambra Avenue. Greg Holloway, who leads Tilehurst, insists every job meets the same coastal-spec standard before the crew leaves the driveway. The reviews from Martinez homeowners reflect that consistency: steady, on-schedule work, no price reshuffles after tear-off, and a cleanup that leaves your garden and gutters cleaner than we found them.
New Roof Installation in Martinez
New Roof Installation in Martinez usually means one of two things: a new build, or a first-time roof on an addition or detached structure. The work is different from a re-roof in one important way: there’s no old material to tear off, so the decking is often new plywood or OSB, and the entire roof assembly goes on fresh. That said, the same Martinez conditions apply. The Carquinez Strait wind funnel doesn’t care whether the house is a century old or finished last month.
For a new roof on a standard Martinez addition or outbuilding, plan on $7,000 to $12,000 for architectural shingles, and $12,000 to $22,000 for a full new-build home roof depending on square footage and pitch. These ranges include the underlayment, drip edge, and a proper fastening schedule. If it’s a new primary residence, we coordinate with your builder through inspected stages so the roof passes the first time.
Wind-Rated Fastening on New Construction
Any new roof we build in Martinez gets a six-nail high-wind fastening schedule, not the standard four-nail pattern that works fine six miles inland. The Carquinez Strait delivers sustained afternoon gusts that regularly exceed California Building Code thresholds for enhanced fastening. Whether it’s new construction or a replacement, we spec to the wind, not to the cheapest bid.
New Decking and Underlayment
Before shingles go down, our crews inspect the decking and replace any sheet that’s soft, warped, or delaminating. Then we lay the underlayment, and in the valleys we run ice and water shield, which stays sealed even when wind-driven rain tries to push sideways into the seam. For a Martinez roof, that’s not an upgrade. It’s baseline.
Reroofing in Martinez
Reroofing in Martinez is replacing the roof on a home that already has one, and that’s the majority of what we do here. The job involves tearing off the old material down to the decking, inspecting and replacing damaged wood, then installing the new roof system: underlayment, drip edge, flashing, shingles or tile, and ridge cap. In Martinez, it also often means handling original wood shake, clay tile, or tar-and-gravel built-up roofing from the 1920s through the 1950s, especially around the historic downtown.
Most Martinez reroofs run $11,000 to $19,000 for architectural asphalt shingles on an average ranch, and $18,000 to $30,000 for a larger hillside home with steeper pitch, older decking, or a two-layer tear-off. If the roof has original wood shake or clay tile, the tear-off is more labor-intensive and disposal is heavier, which pushes toward the upper end. You get a line-item quote before we schedule, and that number doesn’t move unless we find decking damage nobody could see from the outside, which we’ll show you with photos before we replace it.
Tear-Off Depth and Decking Inspection
When we strip an old Martinez roof, we don’t just pull shingles and slap new ones down. We open the roof to the deck and physically check every sheet. On pre-WWII homes, it’s not unusual to find tongue-and-groove decking or skip sheathing that’s held up for a century but needs individual boards replaced around the chimney and valleys. We quote that work upfront.
The Coastal-Spec Assembly
Here’s the thing most homeowners only learn after a mossy failure or a wind-blown delamination: a roof spec’d for Concord won’t survive the same way on a Martinez hillside. We build our Martinez reroofs with a high-wind nailing pattern, stainless or hot-dip galvanized fasteners at all flashing and drip edge, and zinc or copper ridge strips on the north- and west-facing planes toward the strait. It costs a bit more. It’s also the difference between a 25-year roof and a 7-year recurring problem.
Trusted Brands We Service in Martinez
Tilehurst installs products from seven major manufacturers, and you choose, not us. For Martinez specifically, we lean on GAF architectural shingles for their high-wind rating and AlgaeGuard protection, Atlas for their storm- and wind-rated profiles, and Boral for clay and stone-coated steel when your home’s architecture calls for it. OEM specifications matter because every brand’s warranty is tied to the fastening pattern and accessory materials installed with the shingle. We stock stainless drip edge, hot-dip galvanized nails, and zinc ridge strip locally for Martinez jobs, so there’s no week-long wait when it’s time to install.
Common Roof Replacement Problems We See in Martinez Homes
Martinez isn’t a generic East Bay suburb, and its roof failures aren’t generic either. Here’s what we see most often when we walk a Martinez roof for the first time:
- Wind-delaminated shingles from the strait’s afternoon gusts. The Carquinez Strait acts like a funnel. Shingles nailed with a lighter pattern hold fine in Concord, but here they lift, crack, and detach, usually on the ridge and the windward plane facing the water.
- Moss and algae re-colonization on north- and west-facing planes. Nightly marine fog keeps those slopes damp even in July. Plain asphalt shingles can show visible green growth within three to five years, which is why we spec algae-resistant shingles and zinc or copper ridge strips as standard on Martinez reroofs.
- Corroded carbon-steel fasteners at drip edge and flashing. Salt-laden damp from the strait attacks cheap hardware that inland roofs never see fail. We replace it all with stainless or hot-dip galvanized, and we seal the joints instead of relying on overlapping metal alone.
- Aging original materials on pre-WWII homes. The late Victorians and Craftsman bungalows around downtown frequently still have wood shake, clay tile, or tar-and-gravel roofs. These need a specialized tear-off, careful deck inspection, and often selective board replacement before any new roof goes on.
Pricing for Roof Replacement in Martinez, CA
For a standard single-story ranch in Martinez, an architectural asphalt shingle roof replacement runs $11,000 to $16,000. Two-story homes or steep hillside lots run $14,000 to $19,000. If you’re taking off original wood shake or clay tile, add $2,000 to $4,000 for the heavier tear-off. Flat and low-slope roofs run $9,000 to $15,000 for a full replacement with a modern modified bitumen or TPO system. The coastal-spec hardware and zinc ridge strips add roughly $800 to $1,800 to a typical job, and they’re the cheapest insurance you can buy against a moss or corrosion failure. Call (945) 303-9821 for a written, line-item estimate. It’s free, and the number in it is the number on your final invoice.

FAQs About Roof Replacement in Martinez
The Carquinez Strait channels sustained afternoon wind into Martinez at speeds that measurably exceed what Concord or Walnut Creek typically see, and those gusts routinely lift or delaminate shingles installed with a standard four-nail pattern. We install a six-nail high-wind schedule on every Martinez roof because the California Building Code wind provisions for this corridor require enhanced fastening, and because we’ve seen what happens when a cheaper crew ignores it. If you’re comparing bids, ask each contractor to specify their fastening pattern and write it into the quote. Call (945) 303-9821 and we’ll explain the difference in plain English.
Yes. On north- and west-facing planes toward the strait, nightly marine fog keeps the shingle surface damp even in dry summer months, and plain asphalt shingles can show visible moss re-colonization within three to five years. That’s a documented failure timeline here, not a guess, and it’s why we spec algae-resistant shingles and zinc or copper ridge strips as standard on Martinez reroofs rather than an optional add-on. On a 1920s bungalow off Ferry Street near the historic downtown, we tore off two layers of aging wood shake, replaced soft decking, and rebuilt the roof with GAF architectural shingles in a six-nail high-wind pattern over ice and water shield in the valleys, then set stainless fasteners and copper ridge strips to keep the north plane facing the strait from greening up. The homeowner had already seen moss return within four years on the previous plain asphalt job, and this spec stopped that cycle.
Ask every bidder to put four things in writing: the fastening schedule (it should be six nails per shingle for our wind zone), the fastener material at flashing and drip edge (stainless or hot-dip galvanized), whether the bid includes zinc or copper ridge strips on strait-facing planes, and the full tear-off and decking replacement scope. If a bid doesn’t specify those, it’s not apples-to-apples with one from Tilehurst. That’s the whole game in Martinez. We give you a written, line-item quote on the first visit, and you compare it against anyone else’s with the same spec.
We spec stainless or hot-dip galvanized fasteners at every drip edge, flashing point, and penetration, and we seal the joints rather than relying on overlapping metal alone. For shingles, we lean on GAF architectural profiles with AlgaeGuard, Atlas storm-rated options, or Boral clay tile when the home’s original architecture calls for it. Salt-laden damp off the Carquinez Strait attacks carbon-steel hardware that inland roofs never see fail early, so the hardware spec is just as important as the shingle choice. Ask for the coastal spec by name.
In most cases, no. Martinez’s pre-WWII homes often have original wood shake or clay tile, and laying new shingles directly over them hides decking rot and adds weight the framing wasn’t designed for. The right move is a full tear-off to the deck, a board-by-board inspection, selective replacement where needed, and then a properly spec’d new roof. It’s more labor upfront, but it’s the only way to know what’s underneath. Call (945) 303-9821 for a free inspection and a written proposal, and we’ll show you photos of whatever we find before we touch a thing.
