Shingle roofing on a Concord home means tearing off the old layers and rebuilding the roof system from the deck up: synthetic underlayment, ice-and-water shield in the valleys, a new drip edge, and a fresh field of asphalt shingles.
We build for the local climate. Hot, dry summers bake granulated surfaces and fire season winds work nails loose; winter downpours push water into the valley flashing. A laminated architectural shingle handles both better than a thin three-tab.
On 1960s and 1970s ranch-style single-family homes near Willow Pass and Meadow Homes, we often pull up plywood sheathing that has wicked moisture for years. Replacing it now costs less than repairing rot and decay after a leak reaches the ceiling.
Dimensional shingles carry heavier fiberglass mats and thicker granule coverage, so they resist wind uplift and hold color longer. Owens Corning Duration, GAF Timberline HDZ, and CertainTeed Landmark Pro each carry manufacturer warranties worth reading line by line.
Algae resistance matters on shaded north slopes in Concord Hills, and wind ratings matter on every west-facing ridge. We match the shingle to the exposure instead of selling one product to every house on the block.
Not every roof needs replacement. Where granule loss is limited to a few south-facing slopes, we mend the shingles and reseal the flashing, which keeps usable material out of the dumpster.
Every job gets checked against local building code, and we refit the ridge cap, step flashing, and pipe boots rather than reusing worn pieces. Permits and inspection are written into the roof estimate, not bolted on later.
We do not stack a new layer over an old one. A recover or overlay hides deck rot, traps heat, and can void the manufacturer warranty, so we price a full tear-off unless your roof genuinely calls for something else.
When an ice dam builds at the eave, dam removal with steam (steam ice work, not a hatchet) protects the granulated surface. A deep eave overhang helps too, because it keeps meltwater moving instead of freezing at the edge.
We price by the roofing square and check ventilation at the same time. Any roofer who has stripped a rooftop here in July knows how much heat a sealed attic holds.
Soffit vents, a ridge vent, and an attic fan pull that heat out. Insulation over a vapor barrier keeps it from pressing up through the roof deck.
A roof coating or recoat on a low-slope section costs less than replacement and buys years of waterproofing. It will not fix a saturated deck, and we say that before you spend the money.
Shingles are not the only material we quote. Wood shake and cedar shake split in dry heat and need steady maintenance, while slate and clay tile or concrete tile shed water for decades but add weight to the truss and rafter framing.
Metal panel, standing-seam panel, and corrugated panel install faster and throw back summer heat. On flat sections we install single-ply membrane (TPO, EPDM, PVC), a built-up roof, or modified bitumen, and we tell you when old tar and felt should come off.
Roofing felt and tar paper under those old layers show how the roof was built. Torch-applied modified bitumen on a flat rooftop looks simple until a seam lets go in the third winter.
Here is what we check and install when we service a shingle roof:
- Synthetic underlayment rolls over the decking as a second water barrier beneath every field course.
- Ice-and-water shield lines the valley and the eave, where heavy rain and backed-up water do their damage.
- Drip edge caps the rake and the eave so runoff leaves the fascia cleanly instead of wicking behind it.
- Step flashing and counter-flashing close the joints where the roofline meets a chimney, a sidewall, or a dormer.
- Ridge vent and ridge cap finish the peak so the attic breathes without rain following the opening inward.
- Pipe boots and vent boots wrap plumbing stacks and exhaust vents with a molded, hand-sealed collar.
- Gutters and downspouts move roof water off the soffit and away from the foundation.
- A skylight gets apron flashing and boot flashing at every plane change, same as any dormer.
- Parapets and scuppers matter on low-slope and commercial roofing work, where ponding is the real enemy.
- Snow guards and anchors go on where pitch, snow load, or service access calls for them.
- A mansard, gambrel, or steep gable roofline needs custom metal work at the break in pitch.
- A canopy or awning over a doorway can be re-covered in the same shingle run as the main roof.
- Battens and counterbattens create a drainage plane under metal panel and some tile assemblies.
Most shingle roofs here take two to four days from tear-off to final cleanup, weather depending. Steep pitch and heavy deck repair add time. Here is how the work runs:
- We inspect the roof deck, check moisture content, and photograph the substrate before anything comes off.
- A dumpster lands in the driveway, and the crew sets ladders, scaffold, and a safety harness before a pry bar touches a shingle.
- Tear-off with a roofing shovel strips the old shingles, underlayment, and failed flashing down to the plywood or OSB sheathing.
- Rotten sheathing, sagging joists, a settled ridge beam, or a cracked purlin get replaced and re-nailed before we cover anything.
- Self-adhered ice-and-water shield goes along the eaves and valleys, and synthetic underlayment covers the rest of the deck.
- A starter course sets the first row; field courses follow in staggered courses, fastened with ring-shank nails and a nail gun running off an air compressor.
- Ridge cap, hip and verge details come next, then sealant and roof cement at the penetrations, with caulk and adhesive where two planes meet.
- A magnetic sweep and hand pick-up clear every nail and screw from the lawn, and the dumpster leaves with the debris.
If you manage property, we handle permits, inspection scheduling, and insurance paperwork so you are not chasing three different trades. Call +19257224916 and we will walk the roof with you.
Our service area covers Downtown Concord, Willow Pass, Meadow Homes, Lime Ridge, and Concord Hills, plus the blocks out toward the Walnut Creek Staging Area. Residential roofing is most of what we do, with commercial roofing for flat rooftops and property managers.
Between the Concord Pavilion and the slopes below Mount Diablo, sun and wind hit roofs differently. A building near Todos Santos Plaza bakes like the tracts on the ridge above it.
Our customer testimonials come from repeat work and referrals, which is how a licensed, insured roofing contractor stays busy for 38 years.
