Concord Roof Pros provides professional roof replacement in Concord, CA for residential and commercial properties across central and east Contra Costa County. 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. We almost always argue for the tear-off, and the reason is heat.
A second layer of shingles sits on an insulating mat of old asphalt, so it runs hotter through every one of the 45 days a year that Concord clears 90 degrees. Hotter shingles shed granules faster and the factory sealant strip stays soft when it should be set. A recover is only defensible over one existing layer, on a deck with no soft spots and no history of trapped moisture, and even then you give up the inspection.
On a tear-off we walk the bare sheathing, replace delaminated panels and any board that has gone soft under an old flashing leak, then re-nail the field before anything goes back down. We photograph the deck at that stage and send it to you. That inspection is most of what you are buying, and a bid that promises no deck cost at all is a bid that intends to shingle over whatever is under there.
Above the deck the assembly matters more than the brand. We run a synthetic underlayment rather than felt, because felt takes on moisture on damp nights and wrinkles as it dries, and those wrinkles telegraph through the finished shingle within a season. Valleys and eaves get a self-adhered membrane. Rakes and eaves get metal drip edge, not a shingle overhang trimmed by eye.
Everything is Class A rated, which matters more in the hill neighborhoods than in the flats, and we pull the permit and meet the city inspector rather than asking you to. Colors go past your HOA before anything is ordered. We also expect to rework the ventilation while the roof is open, because a new covering over an old vent layout just bakes the same attic under nicer shingles.
If your roof is fifteen years old with one leak at a chimney, we will tell you that is a flashing repair rather than a replacement, and we will write it that way. Replacement is right when the mat has gone brittle across the whole field, when the deck is failing, or when you are already paying somebody for repairs twice a year and getting one dry winter out of it.
Our licensed and insured team brings the right materials and equipment to every job — Class A fire-rated shingle assemblies, SBS-modified bitumen cap sheet, ASTM C920 high-movement joint sealant, floating expansion clips on standing seam, 24-gauge Galvalume panel, reglet-cut counterflashing — and backs the work with a written workmanship warranty. We serve Concord and nearby communities including Pleasant Hill, Martinez, Walnut Creek, Clayton.

Materials, equipment and how we do roof replacement
The difference between roof replacement that lasts and roof replacement that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with Class A fire-rated shingle assemblies, SBS-modified bitumen cap sheet, ASTM C920 high-movement joint sealant, floating expansion clips on standing seam, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Concord job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in central and east Contra Costa County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

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.
The standards behind roof replacement
Quality here is not a matter of opinion — it is written down. The roof replacement work we do in Concord follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
Every roof replacement project in Concord gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
