Metal Roofing in Walnut Creek, CA

Walnut Creek Roofers installs metal roofing built for hot, dry summers, occasional hail, and strong afternoon winds. We hang standing-seam and exposed-fastener panels that shed water instead of soaking it up, with a rooftop expected to last 40 to 50 years. Call (925) 503-1377 for a free estimate.

A metal roof is a panel system, not a shingle field. Standing-seam panels are roll-formed on site and run ridge to eave with no horizontal laps for water to wick under.

Exposed-fastener panels screw through the face of each sheet. They cost less up front, but the gasketed fasteners need checking as the metal expands and contracts in the heat.

Hot, dry summers and winter storm systems here separate the two. Standing seam handles wind uplift better, because hidden clips let the metal move without backing a screw out.

Gauge matters: a 24-gauge panel dents less than 26-gauge when a ladder slips or a branch lands. Finish matters too, and PVDF holds color on a sunny roof better than a thin SMP coat.

Fasteners are specified by panel maker and wind zone. We set each gasketed screw to the depth where the washer seals flat, never overdriven into a dimple that traps water.

Flat sections over a garage or porch call for a membrane instead: TPO, EPDM, or a PVC membrane. A built-up roof or modified bitumen with a torch-applied cap handles the same job on older buildings.

Metal is not always the answer. An asphalt shingle roof, architectural shingle or three-tab, costs less to replace, and a cedar shake, slate, or clay tile roof sometimes mends cheaper than it replaces.

Aluminum, stone-coated steel, and painted steel behave differently near shade, salt air, or a low-slope run. Stone-coated steel mimics wood shake, slate, or concrete tile at a fraction of the weight on your rafters.

What's Included

  • A roof inspection before we quote: deck condition, moisture content in the sheathing, and the state of your flashing.
  • Tear-off of the old roof, or a recover over existing shingles where the substrate passes and building code allows it.
  • Ridge-to-eave underlayment: synthetic underlayment in the field, ice-and-water shield in the valleys, and eave protection above the drip edge.
  • New flashing at the chimney and sidewalls, plus pipe boot, vent boot, and skylight replacements where the seals have gone.
  • Ridge cap, hip caps, and ventilation: ridge vent, soffit vent, or an attic fan if the attic runs hot in July.
  • Panel options in standing-seam steel, exposed-fastener corrugated panel, and stone-coated steel from makers like McElroy Metal, ATAS, and Decra.
  • A line-item roof estimate, permit paperwork, a dumpster on site, and debris haul-off after the final walk-through.

    • Signs You Need Metal Roofing

  • Daylight shows through the roof deck in the attic, or you can see the roofline separate where panels should overlap.
  • Rust streaks, chalking, or a flaking finish on an older metal roof, which usually means the coating has oxidized past resealing.
  • Loose or backed-out fasteners on an exposed-fastener panel, often after wind pushes up under an eave.
  • Granule loss and curled edges on an asphalt shingle roof, a sign of end-of-life wear worth pricing against metal.
  • Water stains on ceiling drywall or a drip you hear after a winter storm, which points to valley or flashing water intrusion.
  • Attic heat and rising summer bills, a sign the insulation and ventilation under the roof need work before any new panel goes on.

    • Our Metal Roofing Process

  • We start with a roof inspection: pitch, deck condition, valleys, flashing, and any rot in the fascia or soffit.
  • You get a written roof estimate with line items for panels, underlayment, fasteners, and labor, so bids compare cleanly.
  • We pull the permit and confirm the panel layout and fastener spacing against local building code for wind uplift.
  • Crews set scaffold and ladders, anchor safety harness tie-offs, and strip the old roof with pry bars and roofing shovels.
  • We re-nail or replace the decking with a nail gun and ring-shank nails, then roll out synthetic underlayment and self-adhered ice-and-water shield.
  • Panels go up in order (drip edge, eave trim, field course, ridge cap), then we reseal penetrations with roof cement or mastic, caulk the boots, and clear the dumpster.
