What the Work Actually Involves, Step by Step

Every project starts with a roof inspection taken from the deck, not from the curb. We lift a few shingles, press the decking for soft spots, and trace any water that has wicked past the underlayment into the plywood.

Then we write a line-item estimate. You see what comes off, what stays, and how many roofing squares the job really covers.

1. We tear off the old asphalt shingles down to the roof deck, pry out the remaining fasteners with a roofing shovel, and drop the debris into a dumpster set in the driveway.
2. We check the decking, replace rotted plywood or OSB, and sister new framing where a truss, rafter, or ridge beam has settled under load.
3. We roll synthetic underlayment across the substrate and set self-adhered ice-and-water shield at the eaves and valleys, where an ice dam would otherwise push meltwater uphill.
4. We hang new drip edge on the rake and eave, then detail chimney flashing, step flashing, counter-flashing, and apron flashing around the chimney, sidewalls, skylight, and pipe boot.
5. We run the starter course along the eave and lay field course shingles in staggered courses, fastened with ring-shank nails held at a depth that keeps them from being overdriven.
6. We set the ridge cap, cut in a ridge vent, and hand-seal each penetration with roof cement and a bead of sealant.

Materials We Install, and When Each One Fits

We choose assemblies by roof pitch, weight, and how the roof sheds water. A steep gable over a bedroom takes a different build than a low-slope flat roof over a garage.

• Architectural shingle and three-tab shingle cover most pitched residential roofing, and both go down over a starter course to resist wind uplift.
• Wood shake and cedar shake shed rain on a steep pitch, but they hold moisture at the butt and need more attic ventilation than asphalt shingle.
• Slate, clay tile, and concrete tile last for decades on a hip or mansard roof, though the framing has to carry the added weight.
• Standing-seam metal panel and corrugated panel bring a metal roof to a gambrel, a carport canopy, an awning, or a deep overhang, and they shed debris quickly.
• TPO, EPDM, and PVC membrane cover low-slope commercial roofing, while modified bitumen and a built-up roof handle a flat roof repair where ponding water sits.
• Self-adhered membranes and synthetic underlayment replace old felt, tar paper, and asphalt-saturated roofing felt that flakes apart in summer heat.

What a Roof Inspection Finds, and Why

Water rarely shows up where the stain is. It seeps in at a valley, wicks along a rafter, and drips out over a soffit a good distance from the entry point.

• Granule loss on an asphalt shingle tells us the mat is near end-of-life wear, and the next hail storm will bruise it.
• Rot and decay in fascia, soffit, or roof deck usually begins where a gutter or downspout has pulled loose and water runs behind it.
• Sag along the roofline, or a ridge that has started to settle, points to a joist or truss carrying weight it was never sized for.
• Caulk and mastic that has dried and peeled off a counter-flashing, pipe flashing, or vent boot is the leak we mend most often.
• Chalking, blistering, or a coating that has begun to spall on a modified bitumen surface means the finish has eroded and the roof is due for a recoat.
• On older homes we also find framing that was undersized from the start, like rafters notched into a purlin or batten strips nailed over a counterbatten at the verge.

How Santa Rosa Weather and Local Roofs Shape the Work

Hot, dry summers with wildfire risk bake the rooftop, and fog plus morning dew keep shingles wet well past sunrise. Heavy winter rain from Pacific storms then finds every small gap.

We size ventilation so the attic can dry itself. Warm air leaking from a house can condense and freeze into steam ice along a cold eave, so a soffit vent paired with a ridge vent, or an attic fan on a low-slope section, moves that moisture out first.

We work rooftops in Roseland, Bennett Valley, Fountaingrove, Rincon Valley, and the West End, and we know how a roof near Annadel State Park, Luther Burbank Home & Gardens, Santa Rosa Creek, or Cochrane Hill ages in that exposure.

Shape changes the plan too. A dormer or parapet collects water differently than an open hip or gable, and a scupper or coping edge on a flat roof needs fresh waterproofing before the seams split.

On low-slope sections we set a snow guard above the valley, anchor the weatherproofing at the perimeter, and confirm the assembly meets local building code. We also correct what causes big bills later: a vapor barrier laid wrong side up, thin attic insulation, or a downspout dumping water at the foundation.

Tools, Timelines, and Honest Cost Drivers

We stay off open roof edges without fall protection. That means scaffold or ladders set on stable ground, safety harnesses tied off, and a roofing square, pry bar, nail gun, and air compressor staged before the tear-off begins.

A torch is the wrong tool for most of our work, so we run self-adhered sheets and cold-applied adhesive where a flame would be a risk near dry grass.

Most residential roof replacement finishes in a few days on a simple gable. It runs longer when we find rotted sheathing or the insurance scope grows mid-job.

Cost drivers stay simple to explain: pitch, how many layers come off, deck repair, ventilation upgrades, and whether the roof allows a recover or overlay instead of a full replacement.

When storm damage or hail damage is involved, we photograph the rooftop, meet the adjuster on site, and build a line-item insurance scope so the claim reflects the real work.

You keep the proof of loss form and the claim deadline in your own hands. We help you read both, and we file the supplemental claim when the first insurance scope comes up short.
