What's actually involved in roof replacement

When you actually need roof replacement

Roof replacement removes the old system down to the deck, repairs any rot, and installs new underlayment, flashing, and shingles or metal panels with a written warranty. Common triggers in Sonoma County: granules in the gutters, daylight through the attic. If you're seeing any of those, get a written estimate before the problem compounds.

What the work actually involves

Standard scope includes asphalt shingle replacement, metal panel replacement, tile replacement, deck repair + ventilation upgrade. Most Sonoma County jobs use Malarkey or TAMKO — both are CSLB-recognized and carry manufacturer warranties. A licensed crew handles permit pulls and inspections; you should never be asked to "skip the permit to save money."

Pricing factors that move the number

The range is $12,000–$45,000 for most Sonoma County homes depending on size, pitch, and material. What pushes you to one end vs the other: square footage and pitch, tear-off layers, decking condition, permit and inspection. A site walk is the only honest way to land an estimate — phone-only quotes are placeholder numbers.

Common Santa Rosa mistakes

Three patterns we see weekly: (1) hiring on price alone — the lowest bid usually skipped permits or warranty; (2) "verbal estimates" that turn into change orders; (3) accepting a contract without checking the active CSLB license number. All three are avoidable in five minutes of due diligence.

Why Santa Rosa homes are different

wine country homes mixed with original ranch builds, atmospheric rivers off the Pacific, wildfire smoke and ember exposure, and Title 24 Cool Roof requirements change how this work has to be done. Santa Rosa, Sebastopol, Windsor, Healdsburg all see the same conditions — older builds running into modern code, PG&E + PSPS resilience needs, wildfire and atmospheric river exposure, and Title 24 / WUI rules adding scope on every permit pull. National-chain advice from a Google search won't price these in. Local jobs need a local estimate.
