Concord Roof Pros: Roof Replacement, Leak Repair & Flashing
Expert residential and commercial roofing services. Free estimates, photographs of what we found, and a straight answer on repair versus replacement.
Licensed and insured California roofing contractor·Permits pulled and city inspections attended·Photographs of every finding, hired or not·Written workmanship warranty on all work
Concord Roof Pros is a licensed, insured roofing contractor in Concord, California, handling roof replacement, roof leak repair, storm damage repair and full reroofs on asphalt shingle, concrete tile, standing seam metal, and low-slope TPO and modified bitumen assemblies. Residential and commercial both, from a single-family tear-off to membrane and curb work on an office or retail roof.
Roofs here work on a daily cycle rather than a seasonal one. Afternoons clear 90 degrees on roughly forty-five days a year and nights drop into the upper 50s, so sealants, flashings and fasteners expand and contract every twenty-four hours. We specify to that: high-movement joint sealant instead of asphalt mastic, reglet-cut counterflashing, floating clips on long metal runs, and SBS-modified shingles that stay flexible rather than going glassy.
Every estimate comes off the roof rather than the driveway, with photographs of what we found and a line-item scope you can compare against anyone else's. We pull the permit, meet the city inspector, and hand over a written workmanship warranty. Where a repair is the honest answer instead of a replacement, we write the repair and say so plainly, including when the right move is to wait for the dry season.
Our Roofing Services in Concord, CA
Roof Replacement
A replacement decision here usually comes down to one question: tear off, or recover over what is already up there. The code allows a recover in some cases.
Roof Leak Repair
Very few leaks start in the open field of a roof. They start where the roof meets something else: a wall, a chimney, a skylight curb, a vent pipe, a valley.
Storm Damage Repair
Storm work here looks nothing like storm work on the plains. Concord does not get many summer cells.
Hail Damage Repair
This is the page where we probably talk you out of something. Damaging hail is rare in the East Bay.
Wind Damage Repair
Most shingles that come off a Concord roof were never stuck down in the first place. That sounds like a technicality.
Roof Inspections
The right time to inspect a roof in Concord is September or early October, before the first real rain. The wrong time is whenever a door-knocker suggests it.
Asphalt Shingle Roofs
Asphalt shingles cover most of Concord, from the postwar tracts along the Monument corridor to the newer hillside subdivisions east of town, and they are usually the right answer. The choices worth having an opinion about are the mat, the sealant behavior and the reflectance.
Standing Seam & Metal Roofing
Metal is a very good roof in Concord and a bad one if the wrong system gets used. The dividing line is how the panel is fastened, and it is worth understanding before you compare bids, because the cheap version fails here for a specific and predictable reason.
Concrete & Clay Tile Roofs
On a tile roof the tile is not the waterproofing. The underlayment is.
Flat & Low-Slope Roofing
Most low-slope roofing in residential Concord is not a whole roof. It is a section: a flat-topped addition, a carport, a rear porch, or the deck over a garage that somebody framed at half a degree of pitch and hoped for the best.
Roof Coatings & Sealing
Two opinions up front, because they will save you money. A coating does not belong on an asphalt shingle roof.
Attic & Roof Ventilation
Ventilation is the cheapest thing on a roof and the most often done backwards. The usual mistake is adding exhaust.
Skylights & Sun Tunnels
Half the skylight calls we take in winter are not leaks. They are condensation, and the fix is not on the roof at all.
Gutters & Downspouts
Concord rainfall arrives in an awkward shape for gutters: about twenty-four inches a year, nearly all of it in a few winter months, with a one-day record of almost four inches. A gutter here sits dry for half the year, then moves all of it at once.
Fascia & Soffit Repair
Fascia rot in Concord is rarely a rain problem. It is a dew problem plus a paint problem, and it starts in the same three places on almost every house: the miters at the corners, the cut ends where two boards butt, and the strip hidden behind the gutter.
Chimney & Wall Flashing
A chimney is a masonry column standing in a wood roof, and the two do not move together. That is the entire problem.
Emergency Roof Tarping
Honest first: from May to October, most Concord roofs that are leaking do not need a tarp. They need a repair scheduled inside the dry window, and paying emergency rates in August is usually paying for urgency that the weather is not going to supply.
Commercial Roofing
Commercial roofs in Concord are a specific inventory: the mixed-use blocks around downtown, retail strips along the Monument and Contra Costa Boulevard corridors, light industrial near Buchanan Field, and office floors out by the BART station. Nearly all of it is low-slope membrane carrying a great deal of equipment.
Insurance Claim Help
The most useful thing we can tell a Concord homeowner about roof insurance is this: most roof failures we see here are not covered, and learning that early saves you a claim on your record in exchange for nothing. California homeowner policies pay for sudden accidental physical loss.
Why Concord Chooses Concord Roof Pros
- ✓Estimates come from on the roof and in the attic, never from the driveway or from a satellite measurement alone.
- ✓We specify high-movement joint sealant and reglet-cut counterflashing, because asphalt mastic does not survive a daily temperature swing.
- ✓Long metal runs get floating clips and concealed fasteners, so panels can move without wallowing out several hundred screw holes.
- ✓Tile roofs get quoted as a lift-and-relay first, since the underlayment is what expired and the tile itself usually has decades left.
- ✓We will tell you when there is no insurance claim, no hail damage and no reason to replace a roof that still has years in it.
- ✓Deck repair and ventilation changes are separate priced lines on the estimate, so the invoice at the end matches the number at the start.
About Concord Roof Pros in Concord, CA
Concord Roof Pros works central and east Contra Costa County, and the roofs we see all week are the same handful of assemblies: architectural shingles over the postwar tracts and the Monument corridor, concrete tile on the tract subdivisions built from the late seventies onward, standing seam and exposed-fastener metal on shops and additions, and low-slope membrane on everything commercial. Our crews specialize in the details those assemblies fail at, which is almost never the open field.
We price off measurement and photographs, name products by specification rather than by tier, and put deck repair and ventilation changes on the estimate as separate lines so nothing arrives as a surprise mid-job. Licensed and insured in California, permits pulled in your name, inspections attended, and a written workmanship warranty issued alongside the manufacturer paperwork. We are also happy to be the second opinion on somebody else's bid.
Here is when not to hire us. If a door-knocker has convinced you that a passing storm entitles you to a free roof, we are the wrong call, because we will inspect it and tell you what actually happened up there. If you want the cheapest number, somebody will beat us by skipping the tear-off, the drip edge or the permit. And if your roof has eight good years left, we will say so and decline the job.

How It Works
We get on the roof and photograph it
No driveway estimates. We walk every slope, check the boots, flashings, sealant joints and fastener heads by hand, then go into the attic with a light. You get the photographs whether or not you hire us, including the ones that show nothing is wrong.
A line-item scope, not a lump sum
The estimate names the underlayment, the shingle or membrane, the flashing details and the ventilation changes, each priced separately. That is what lets you compare bids honestly, and it is why our number sometimes looks higher until you read what the other one left out.
Tear-off, deck inspection, then the roof
We strip to bare sheathing, photograph the deck, and call you before replacing any panel so nothing appears on the invoice as a surprise. Then underlayment, flashings, field, and the ridge and vent work, with the site cleaned and magnet-swept at the end of each day.
Final walk, inspection sign-off, warranty
We walk the finished roof with you, check the gutters and downspouts run clear, meet the city inspector for the final, and issue the written workmanship warranty alongside the manufacturer paperwork. If something needs a second visit in the first rain, that visit is ours.

What Concord Customers Say
Two other bids said full replacement. These guys water-tested it, found a split vent boot and a chimney counterflashing stuck on with caulk, fixed both, and charged a few hundred dollars. Roof is dry through two winters now.
Tear-off on a 1962 ranch. They photographed the bare deck, called me about two soft panels before replacing them, and the final number matched the estimate line for line. The inspector signed it off without a single correction.
Our concrete tile roof was thirty-one years old and I assumed we were buying new tile. They lifted and relaid it with new underlayment for a fraction of that, reused every whole tile, and replaced the cracked ones from stock.
Called about hail after a storm. They inspected, showed me photographs of blisters and granule loss, and told me plainly it was heat damage and not a claim. Then they quoted the boots and sealant work that actually needed doing.
Commercial roofing for Concord property owners and managers
Commercial work here is mostly low-slope membrane carrying a great deal of rooftop equipment: retail strips along the Monument and Contra Costa Boulevard corridors, light industrial around Buchanan Field, downtown mixed-use, and office floors near the BART station. Membrane fields rarely fail on their own.
Curbs, condensate lines, disconnects and pipe penetrations do, because each one is a joint cycling with a thirty-degree daily swing while a technician stands on it twice a year.
We flash curbs with metal and welded target patches, set walkway pads on every service route, and hand property managers a surveyed roof plan with defects photographed and prioritized, so a roof becomes a budget line instead of an emergency call in December.
- ✓TPO and PVC single-ply, heat-welded seams, 60-mil minimum
- ✓PVC specified over restaurant kitchens where grease attacks TPO
- ✓Rooftop HVAC curb flashing and equipment re-detailing
- ✓Modified bitumen two-ply on small penetration-heavy areas
- ✓Roof condition surveys with a marked plan and priority list
- ✓Maintenance programs with pre-season and post-storm visits
- ✓After-hours and phased work so tenants keep operating
- ✓Silicone restoration coatings where the substrate is still sound
Frequently Asked Questions
What does a roof replacement cost in Concord?
We will not publish a square-foot number, because the honest range is too wide to be useful and every contractor quoting one online is guessing at your roof.
Cost here is driven by five things: total squares and pitch, how many existing layers come off, how much sheathing needs replacing, the number of penetrations and flashing details, and the product tier. A simple single-story tear-off with clean details sits at one end.
A steep cut-up roof with three chimneys, a low-slope section and a bad deck sits far from it. We measure, photograph, and give you a line-item number that holds.
How long should a roof last in this climate?
Longer than a hail belt and shorter than the package says. Concord has no freeze-thaw cycle to speak of and very little damaging hail, which helps. What it has instead is ultraviolet exposure and a thirty-degree daily temperature swing across forty-plus days above 90 each summer, which is hard on asphalt binders, rubber boots and sealant joints.
A well-installed architectural shingle roof with good ventilation commonly gives twenty to twenty-five years here. Concrete tile lasts fifty years or more, but the underlayment beneath it does not, and that is the item people get surprised by at year thirty.
Do I need a permit to reroof my house?
Yes. Reroofing is permitted work in California, and the permit covers more than paperwork: it triggers an inspection of the assembly, the fire rating of the covering, and in many cases the ventilation and the underlayment. We pull it in your name, schedule the inspection, and meet the inspector on site.
A contractor who offers to skip the permit is offering to save a few hundred dollars now and hand you a problem at resale, when a buyer's agent asks for records of the roof and nothing exists.
Will my homeowners insurance pay for a new roof?
Usually not, and it is better to hear that early. California homeowner policies pay for sudden accidental physical loss and specifically exclude wear, deterioration and age. A roof that has simply aged out, however bad it looks, is a maintenance expense.
A limb through the sheathing in a January storm, or wind-driven rain forced into a flashing during a frontal passage, can be a covered event. We inspect, document the mechanism with dated photographs and moisture readings, tell you honestly which category you are in, and meet your adjuster on the roof where there is a real claim.
When is the best time of year to reroof in Concord?
Late spring through early autumn, for a reason that is specific to asphalt shingles. Each course seals itself to the one below with a heat-activated adhesive strip, and that strip needs sustained warmth to flow and bond.
Install in a cool damp February week and the roof can sit unbonded for months, which is where most wind losses in this valley actually come from. Tile relays and single-ply membrane work are less season-dependent. If you have an active leak in December we will repair it immediately and schedule the reroof for the dry window.
My roof is tile. Do I need all new tile?
Almost certainly not. On a tile roof the tile is the wear layer and the underlayment is the waterproofing. Most of the concrete tile in the Diablo Valley went down between the late 1970s and the 1990s over a single layer of 30-pound felt, and that felt is the part that expires, usually around year twenty-five.
The right work is a lift-and-relay: stack the tile, strip the old felt, replace bad sheathing, install a new membrane and set the same tile back with new fasteners and flashings. You keep the expensive part.
