We know the neighborhoods from Todos Santos Plaza out to Clayton Valley. We know the 70s ranch houses with skip sheathing and the mid-century homes along Concord Boulevard that need decking replacement before the first shingle goes down. Dylan Pace leads our crews and he answers direct questions directly. Call (325) 246-5075 and you will get a live person, a straight answer, and a written price before any work starts.
Read on and you’ll know exactly what a replacement here involves start to finish: permit, sheathing inspection, dry-in, flashing, final. You’ll know the local cost drivers. You’ll know what changes a price mid-job and what should never change it.
Why Crestview Roofing Is Concord’s Preferred Roof Replacement Company
Concord homeowners ask us three questions before they sign. Who is actually coming to my house? What does it cost, in writing? What happens if something goes wrong? We answer all three before the contract is ever mentioned.
Every Crestview technician is background-checked and uniformed. When your crew arrives, you’ll know their names and their arrival time before they pull into your driveway, because The Relay Standard sends a live trackable arrival window. That’s not a sales pitch. It’s the way we’ve run jobs since Crestview was founded in 2000, and it’s the same standard every Roof Replacement job follows, whether it’s a 16-square reroof near Clayton Road or a full decking replacement in the Ellis Lake area.
Our 365-Day Done Right Promise is the second answer. Any covered repair that fails within 365 days gets corrected at no charge. If that means a second visit, that visit is free too, no negotiation, no runaround. Every repair and every replacement comes with a written guarantee, included at no extra cost. We don’t sell you a warranty. We attach one to the job.
The Concord market runs on referrals. When a neighbor near Woodside Elementary sees a clean tear-off, a dry-in that holds, and a final inspection that passes on the first visit, they call the number on the truck. That’s been our growth model here since day one.
Reroofing in Concord
Reroofing in Concord means removing the existing roof layer and installing a new roof system over the same structure, and for most Concord homes built between 1960 and 1990, it’s the most cost-effective path to a new roof. A standard reroof here runs $12,000 to $24,000 depending on square count, pitch, and how much decking has to be replaced once the old layer comes off.
The difference between reroof and full replacement
Reroofing removes the existing shingles and underlayment, then installs new underlayment and shingles over the existing decking. A full replacement goes further: it replaces the decking itself. If your plywood or skip sheathing is rotted, delaminating, or sagged between rafters, a reroof will not fix it. In Concord, we find rot most often on north-facing slopes and under valleys on homes with mature tree cover.
When Concord homeowners choose reroofing
If your decking is sound and your roof structure is solid, reroofing saves real money. The tear-off is faster, the lumber cost disappears, and the final inspection usually happens the same week. We’ll tell you if your home qualifies for reroof and what an honest decking assessment looks like once the old layer is off.
Flat Roof Replacement in Concord
Flat roof replacement in Concord applies to a specific set of homes here: mid-century moderns in the Todos Santos area, some ranchers on the north side of Monument Boulevard, and a fair number of garage and addition roofs throughout the city. A flat roof replacement in Concord typically runs $9,000 to $18,000 for a standard residential low-slope roof, depending on square footage, insulation strategy, and the membrane system you choose.
Membrane choices on Concord flat roofs
Most Concord flat roofs we replace use either modified bitumen or TPO. Modified bitumen is tough against ponding water and tree debris. TPO reflects heat, which matters in Concord summers when rooftop temperatures climb past 140 degrees. We do not reuse old flashing on a flat roof. The metal transitions at parapet walls and scuppers are the first places a flat roof fails in our experience.
Drainage is the real scope on flat roofs
A flat roof that is not flat is a problem. The slope, the drains, and the overflow scuppers all have to work or the new membrane fails early. We inspect the drainage path before we quote, and we show you photos of what we find. If your flat roof has a history of ponding, that is a scope item, not a surprise we introduce after the job starts.
Trusted Brands We Service in Concord
We install and repair manufacturer-backed roofing materials from GAF, Owens Corning, and IKO, and we stock common colorways and ridge vent profiles for quick turnaround on Concord jobs. When your home needs a specific shingle match for a partial replacement or an eyebrow vent detail, we can pull it from local supply houses within a day or two. Material quality is never a question on a Crestview job, because every shingle we install carries the manufacturer’s own warranty behind our 365-day Done Right Promise.
Common Roof Replacement Problems We See in Concord Homes
- Wet-season dry-in failures. Concord gets 20+ inches of rain almost entirely between November and March. If a tear-off is not dried in properly before rain hits, decking and underlayment get soaked, and we have seen sheathing rot appear within one wet season when the dry-in was staged wrong.
- Clay soil movement and structure stress. Concord sits on expansive clay in many neighborhoods. Over time, subtle foundation movement opens hairline gaps at flashing points and ridge lines. A replacement that reuses old flashing hides the damage. We replace flashing rather than reuse it, every time.
- Tree debris from mature canopies. The Todos Santos area and older neighborhoods near Ellis Lake have mature oaks and sycamores that drop debris into valleys and behind chimneys. If flashing is not replaced during the job, water backs up under the new shingles and shows up as a ceiling stain the first big storm.
- Permit sequencing mistakes. Concord requires a sheathing inspection before underlayment goes down on a reroof. If that step is skipped, the job cannot be signed off and the roof is not legally closed. We pull permits for every replacement, schedule the inspections ourselves, and pass them on the first visit.

Here are the honest numbers for Concord. A standard architectural shingle replacement on a 1,800 to 2,400 square foot home runs $14,000 to $22,000.

FAQs About Roof Replacement in Concord
A square is 100 square feet of roof area, and a typical Concord single-family home runs 18 to 28 squares, with some larger ranch styles near Clayton Valley reaching 32. To compare two bids, check three numbers line by line: the square count each contractor measured, the scope of decking replacement each included, and the exact material spec each listed. If one bid assumes no decking replacement and the other assumes half the roof, the prices are not comparable. Call (325) 246-5075 and we’ll walk your roof measurement with you.
Yes, a roof replacement in Concord requires a city permit, and the inspection sequence follows a specific order. The city requires a sheathing inspection after the old roof is torn off and before the underlayment goes down. Some projects also require a final inspection after the roof is complete. We pull the permit, schedule both inspections, and pass them on the first visit.
The most common price change on a Concord replacement is decking replacement. The original sheathing is often 1×6 skip boards on older homes, and rot near valleys, eaves, and penetrations is not visible until the shingles come off. Other legitimate changes include rotted fascia behind rusted drip edge, and damaged ridge boards. These are scope items, and we document each with photos before we proceed. The price does not change because someone guessed wrong on materials or labor hours.
Yes, but the schedule is tighter because Concord gets most of its 20+ inches of rain between November and March. That means dry-in timing matters more. Our crews stage the tear-off and dry-in as a single weather-tight sequence, so the decking is covered before rain has a chance to hit it. A roof replace left open to weather for even two days can soak the underlayment and decking, which causes problems later. Call (325) 246-5075 and we will give you a realistic winter timeline for your street.
Yes, architectural shingles outperform three-tab in Concord’s wind conditions, but installation matters as much as the material. The shingle must be nailed in the correct pattern with the correct number of nails per shingle, at the correct overhang. Our crew tore off a 24-square, 22-year-old three-tab layer on a 1970s ranch in Clayton Valley, re-decked where the original 1×6 skip sheathing had sagged, and laid new architectural shingles from GAF with a full ice and water shield along the valleys and all penetrations. The old drip edge had rusted through and the fascia behind it was soft, so we replaced both before hanging new gutter apron. That job passed its final inspection without a re-inspection fee, and it’s the standard we hold for every Concord roof.
