When it's time to replace your siding

Siding rarely fails all at once. In Santa Rosa's hot, high-UV inland summers, you'll usually see it first as faded or chalking paint, warped or cupped boards, soft or rotted trim, woodpecker or pest damage, and rising energy bills as the wall assembly loses its weather barrier. Older T1-11, hardboard, and aging wood siding are especially prone to moisture intrusion once the finish breaks down.

A full replacement solves what patch-and-paint can't: we remove the old cladding, inspect and correct the sheathing, and rebuild the weather-resistive barrier and flashing so the wall drains and dries the way it should.

Choosing the right material

Different homes call for different cladding. We install and can walk you through the trade-offs on each:

• Fiber cement siding (including James Hardie) — noncombustible, dimensionally stable, and a strong fit for high-UV and fire-conscious sites.
• LP SmartSide — engineered wood with an authentic wood-grain look and lighter weight.
• Vinyl siding — low-maintenance and budget-conscious.
• Wood, T1-11, and specialty siding — for historic and character homes, plus aluminum and mobile-home cladding.

Our process

1. Consultation — we assess your existing walls, condition, and goals on-site.
2. Specification — material, profile, color, and detailing chosen for your home.
3. Permit & review — we pull the required building permit and address any applicable review.
4. Tear-off & inspection — old siding removed and sheathing inspected for hidden damage.
5. WRB & flashing — weather-resistive barrier and flashing installed at windows, doors, and penetrations.
6. Installation — new siding installed to manufacturer specification.
7. Finish & walkthrough — trim, caulk, paint as specified, and a final walkthrough with you.

Local relevance: rebuilding and hardening in Santa Rosa

The October 2017 Tubbs Fire destroyed more than 5,600 structures across Sonoma, Napa, and Lake counties, with roughly 2,900 homes lost in Santa Rosa alone — including about 1,300 structures in Coffey Park and heavy losses in Fountaingrove. Rebuilding continues years later, and in 2026 the city adopted redrawn fire-hazard maps that moved thousands of additional properties into higher-risk zones.

That context matters for cladding. Santa Rosa has a designated Wildland-Urban Interface (WUI) Fire Area, and new construction within it must meet Chapter 7A of the current California Building Code, which requires exterior walls to be noncombustible or ignition-resistant. Chapter 7A is performance-based — there is no single approved-products list — and re-siding can trigger current standards for the work you touch. Whether your specific address falls in a mapped zone determines what applies, so we confirm the requirements for your property before we spec the job. Noncombustible cladding like fiber cement is one part of a fire-hardened exterior, alongside eaves, vents, and windows. (We don't give insurance advice — talk to your carrier about coverage.)

Frequently asked questions

Do I need a permit to replace siding in Santa Rosa? A full re-side generally requires a building permit. We handle the permitting for your project.

Does my home need fire-rated siding? It depends on whether your property is within Santa Rosa's WUI Fire Area or a mapped fire-hazard zone. We verify the requirements for your address before specifying materials.

How long does a re-side take? It varies with home size, material, and detailing. We give you a schedule after the on-site assessment.

What drives the cost of a siding replacement? Home size and number of stories, the material and profile you choose, the condition of the sheathing behind the old siding, trim and detailing complexity, and any fire-zone requirements.
