What Does Roof Replacement Involve?
Roof replacement is a full system overhaul. Unlike a repair or overlay, we remove every shingle, nail, and piece of underlayment down to the wood deck. That tear-off lets us inspect the substrate for rot, decay, and sag that would otherwise ruin a new roof in a few seasons.
For a typical 2,000-square-foot home in Novato, the process takes 2–4 days. We use ring-shank nails for superior grip, a self-adhered ice and water shield along the eaves and valleys, and a starter course at the roofline to prevent wind uplift. Field courses are laid in staggered courses, so water has no straight path to the deck.
We've replaced roofs on 1960s ranches in Ignacio, modern townhomes in Black Point, and waterfront properties in Bel Marin Keys. Each has its own quirks — a flat section that pools water, a chimney flashing that was hand-sealed with tar, or decking that wicks moisture from years of foggy mornings. We address those before the new shingles go on.
One job in Pacheco Valle taught us to always check the decking before quoting. The homeowner's old roof had been recovered twice, hiding advanced rot. We had to replace 12 sheets of plywood. That's why our estimate includes a decking inspection — you won't get a surprise bill halfway through.

How Much Does Roof Replacement Cost in Novato?
Roof replacement costs between $8,000 and $25,000 for most Novato homes, depending on size, pitch, and material. Asphalt shingles run $4–$8 per square foot installed. Metal roofs — a smart choice for wildfire-prone areas — run $12–$18 per square foot. Tile and slate are higher.
The biggest cost driver is the tear-off. Removing two layers of old shingles takes longer and produces more dumpster weight. We'll tell you upfront if your roof qualifies for a single-layer overlay — but we rarely recommend it. An overlay hides problems and shortens the new roof's life.
Permits in Novato run $200–$500. We handle that paperwork. Your final price includes dumpster rental, crew labor, materials, and cleanup. No hidden charges.
We use GAF and Owens Corning materials, both with 30–50 year warranties. Labor is backed by our 5-year workmanship guarantee. If a shingle blows off or a flashing leaks, we fix it free.
When Do You Need Roof Replacement Instead of Repair?
Roof replacement is necessary when the roof has reached end-of-life wear. That means granule loss on 30% or more of the shingles, widespread cracking, or curling edges. If you see daylight through the roofline, or water stains spreading across your ceiling, the decking is already compromised.
Storm damage from the heavy winter rains we get in Marin County can also push a roof past repair. Hail, wind, and falling branches can cause punctures, tears, and holes. If shingles are scattered across your yard, that's a sign the roof is done.
But not every leak means replacement. If the damage is isolated to one flashing or a small area, repair is the right call. We'll be honest about that. We've mended plenty of roofs that just needed a reseal or a few new shingles.
Book a free inspection and we'll tell you exactly where your roof stands. We serve all of Novato — from Hamilton to Olompali State Historic Park. We know the local climate: foggy mornings, hot afternoons, and the occasional deluge that tests every roof.
Our Roof Replacement Process
- Inspection and estimate. We climb up, check decking, flashing, and ventilation, then give you a fixed quote.
- Tear-off. We strip all old layers down to the deck. This takes 1–2 days for an average home.
- Deck repair. We replace any rotted or sagging plywood. You'll see it before we cover it.
- Underlayment and flashing. We install self-adhered ice and water shield in valleys and eaves, then new step flashing around chimneys and walls.
- Shingle installation. We lay starter course, then field courses with staggered seams, using ring-shank nails for wind resistance.
- Cleanup and final walkthrough. We magnet-sweep the yard, haul away debris, and walk the roof with you.
Most projects finish in 2–4 days. We schedule around weather — no point starting a tear-off the morning a Pacific storm rolls in.
