Fast, Reliable Roof Replacement Across Concord
A full roof replacement in Concord typically runs $14,000-$28,000 for a standard single-story ranch home, depending on square footage, tear-off requirements, and whether the original wood shake has rotted the decking underneath. Most jobs take 3-7 working days once materials are on site. If you’re in Concord and your roof is at the end of its life, call (945) 303-9821 and we’ll give you a written price before any work starts.

The crew that shows up is background-checked and uniformed, and the person who answers your call is a live human, any hour, any day. You’ll get a straight answer about what your roof needs and what it costs.
Why Tilehurst Roofing Is Concord’s Preferred Roof Replacement Company
Tilehurst Roofing is part of the Kingswell family of roofing companies, founded in 2000, and we built our Concord presence specifically for homeowners who have already been let down by a contractor. Maybe a crew no-showed. Maybe the price changed at the door. Maybe a repair failed within a month. Those are exactly the problems we’re organized to prevent. Every job starts with a written price in your hands before a single nail is driven, and every repair carries a written guarantee delivered before the crew leaves the property, not mailed later.
Concord homeowners regularly tell us the same thing: the difference was that we answered the phone, showed up in the window we gave, and put the guarantee in writing. Greg Holloway leads our team with a simple standard: say the price before the work, show up when we said we would, leave the property cleaner than we found it, put the guarantee in writing, and come back if it fails. That’s the Kingswell Way, and it applies to every roof replacement we do in Concord.
We also know Concord’s building stock and climate in a way an out-of-town crew doesn’t. The 1960s and 70s ranch tract homes that dominate the central and eastern flatlands carry specific failure patterns, and we scope for those before we quote.
New Roof Installation in Concord
New Roof Installation in Concord is the right call when a homeowner is building an addition, putting up a detached shop or ADU, or replacing a roof so far gone that patching no longer makes sense. On a new build or a major addition in Concord, the scope includes decking, underlayment, drip edge, flashing, shingles or flat-roof membrane, and ridge ventilation, all matched to the existing house or the new structure’s plan.
A new asphalt shingle roof on a typical 1,400-1,800 square foot Concord ranch runs roughly $12,000-$20,000. Architectural shingles add $2,000-$4,000 on that same footprint. For a new-build or detached ADU roof, the cost is usually folded into the project’s framing and permitting package, but we’ll give you a line-item price either way so you see exactly what the roofing portion costs.
New Construction Roofing
When we roof new construction in Concord, we coordinate with your general contractor and pull the county-required permits for the roofing scope. The roof has to be sequenced with framing, electrical, and solar rough-in, so we come when the deck is ready and not a day before. We also make sure the underlayment and flashing details are correct before the cladding crew moves on, because retrofitting flashing on a finished wall costs twice as much.
Replacement on Additions and ADUs
Detached ADUs and shop roofs in Concord often have low-slope or flat sections that need a membrane system rather than shingles. We run those with modified bitumen or TPO depending on exposure and the county’s energy-code requirements. The estimate covers the roof assembly and the tie-in where the new roof meets the old, which is where leaks show up if the detail is rushed.
Reroofing in Concord
Reroofing in Concord is what we do most often: tearing off the old roof and installing a new one, rather than laying a second layer over failing material. In Concord’s flatland tracts, many of the original roofs are wood shake or single-layer composition from the 1960s and 70s, and Contra Costa County fire-zone reclassifications plus insurance carriers are now forcing tear-offs to Class A assemblies instead of overlays.
A standard reroof on a single-story Concord ranch with composition shingles runs $13,000-$24,000. If the old roof is wood shake, disposal fees and the decking repairs exposed underneath can add $2,000-$6,000 to the final number. We give you the line-item price up front, including disposal, so the number you sign is the number you pay.
Tear-Off and Decking Repair
Most Concord reroofs begin with a full tear-off down to the sheathing. On these 50- to 60-year-old homes, the decking under the original shake or the first composition layer is often soft at the valleys and along the eaves, where decades of small leaks have done quiet damage. We replace that bad wood before we lay new underlayment. Skipping that step means the new roof goes over rot, and the warranty won’t mean much when the nails won’t hold.
Class A Fire-Rated Assembly
When the carrier or the county requires a Class A fire-rated roof, the shingle is only part of the story. The assembly includes the underlayment, the decking, the flashing, and the ridge vent, all working together. We install full GAF and Atlas architectural shingle systems that carry the Class A rating as a complete assembly, not just a shingle label.
Trusted Brands We Service in Concord
We carry material options from seven major manufacturers, so the product fits the home rather than whatever happens to be on the truck: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Concord’s hot Diablo Valley summers, we often recommend GAF architectural shingles with their adhesive strip formulation, and for homeowners wanting a heavier slate look, Boral’s composite options hold up well in full sun exposure. We keep local stock of the common colors and profiles, which shortens lead time for Concord reroofs, and if you need a specific match to an existing section, we’ll bring samples to your property before the contract is signed.
Common Roof Replacement Problems We See in Concord Homes
- Wood-shake tear-offs that become sheathing jobs. Concord’s 1960s and 70s flatland tracts still carry thousands of original wood-shake roofs, and once the shake comes off, the decades-old decking underneath is often soft at the valleys and eaves. The sheathing, not the shingle, drives the real scope on these jobs.
- Adhesive strip failure from Diablo Valley heat. Concord regularly hits 100°F and above in summer, far hotter than coastal cities 20 miles west, and that attic heat cooks early-generation adhesive strips and granules. A cheap overlay on a low-pitch ranch roof fails years ahead of schedule here.
- Ridge caps and flashing lifted by Diablo winds. When the hot, dry winds funnel through the valley gaps, they pry at ridge caps, flashing, and drip edge on exposed flatland lots. Any tear-off that reuses worn fastening or skips proper underlayment at the edges loses the ridge on the first strong blow.
- Insurance-mandated Class A replacement. Carriers and the county fire-zone map are now forcing many Concord homeowners to tear off and replace with Class A rated assemblies. We handle the disposal, the permit paper, and the decking repairs these tear-offs expose, and the result satisfies the carrier on the first inspection.
Pricing for Roof Replacement in Concord, CA
You’ll get a written, line-item price before any work begins, and we don’t change the number at the door. As a guide for Concord’s market: a full tear-off and reroof on a 1,400-1,800 square foot single-story ranch runs $13,000-$24,000 with architectural shingles. A new roof on a new addition or ADU runs $12,000-$20,000 for the same footprint. Wood-shake tear-off with decking repair adds $2,000-$6,000 depending on how much sheathing has to come out. Flat or low-slope membrane sections run $9-$14 per square foot installed. The final number depends on square footage, pitch, decking condition, and shingle choice, and we walk you through all of it before you sign. Call (945) 303-9821 for a free estimate with the actual numbers, not a ballpark.
Concord’s 1960s-70s central and eastern flatland tract homes are still dense with original wood-shake roofs, and Contra Costa County fire-zone reclassifications plus insurance carriers are forcing tear-offs to Class A assemblies rather than overlays. That means disposal and the decking repairs exposed underneath, not the shingle itself, drive most of the scope on these jobs. We scope for that on every Concord reroof.
We tore off a failing 1970s wood-shake roof on a single-story ranch just off Clayton Road in the Concord central flatlands recently. The homeowner’s carrier had flagged the shake and the county fire-zone map had already reclassified the parcel. Stripping to the deck exposed long runs of dry-rotted sheathing at the valleys, so we replaced the bad decking, laid ice and water shield in the valleys and along the eave, set new drip edge and fascia where the old wood had crumbled, and finished with a GAF architectural shingle system and a ridge vent. The result was a Class A assembly that satisfied the carrier’s fire requirement and ended a recurring leak the homeowner had been chasing for two seasons.

FAQs About Roof Replacement in Concord
In Concord, roof replacements are permitted through Contra Costa County’s building department, not a separate city permit office, for most standard reroofs on existing single-family homes. The county reviews the roof assembly for fire rating and structural loading, and we pull the permit, schedule the inspection, and make sure the final sign-off is on file. Call (945) 303-9821 and we’ll handle the whole permitting path for you.
In most cases, the shake has to come off, not be overlaid. Contra Costa County fire-zone reclassifications and your insurance carrier will typically require a Class A fire-rated assembly, which means full tear-off to the deck, new underlayment, and a rated shingle system. We also find that the decking under original shake in Concord’s flatland tracts is often soft and needs repair before the new roof can go down. Call (945) 303-9821 for an exact assessment on your specific parcel.
Yes, and in Concord it’s more common than in the surrounding hillside cities. Decades-old decking under original shake or the first composition layer is frequently rotted at the valleys and along the eaves, where small leaks have been working for years. We always write the estimate to include visible decking repair, and if more is exposed during tear-off, we show you photos, give you the exact additional line-item cost, and get your approval before we proceed. The price is never just changed without you seeing it.
Concord sits deep in the Diablo Valley and routinely hits 100°F and above in summer, which is far hotter than coastal Bay Area cities just 20 miles west. That sustained heat accelerates shingle granule loss and dries out adhesive strips, so a cheap shingle that would be fine in Berkeley fails early here. We recommend architectural shingles from GAF or Atlas for Concord homes because their adhesive formulations and granule density stand up better to triple-digit thermal cycling. Call (945) 303-9821 and we’ll walk you through the options.
Yes, if the edge and ridge details are done right. The Diablo wind events that funnel through the valley gaps lift vulnerable ridge caps and flashing, and the failure point is usually the fastening and the underlayment detail at the edges, not the shingle itself. On every Concord reroof, we replace drip edge, set new fastening along the ridge, and detail the underlayment at the eaves and valleys specifically for wind-driven rain. Call (945) 303-9821 for a written estimate on your roof.
