We know you have options. But when it comes to your Novato home, a shingle roof isn't something to gamble on. Here's how we stack up against the two most common alternatives.
| Factor | DIY | Cheap Competitor | North Bay Roofing Co. |
|---|---|---|---|
| Materials | Big-box store shingles (often seconds or off-brands) | Lowest-bid shingles, often unbranded | Malarkey, CertainTeed, GAF, Owens Corning, IKO, Atlas |
| Warranty | None on labor; material warranty voids if not installed per code | 1-2 year labor warranty (if any) | 25-Year Workmanship Warranty on all replacements |
| Safety | No insurance; you're liable for injuries | Often uninsured or minimal coverage | Full Liability & Workers Comp Insurance, CA CSLB #1043871 |
| Time | Weeks (weekends only, learning curve) | Rushed, often cutting corners | Efficient crew, typical 2-3 days for a standard home |
| Cost | Low upfront, high hidden costs (tools, mistakes, dump fees) | Low bid, but change orders and callbacks add up | Fair, transparent pricing with no surprises |
| Result | Leaks, voided warranties, possible structural damage | Uneven shingles, nail pops, premature failure | Professional, code-compliant roof that lasts |
We don't just talk about quality—we prove it. Here's a recent job that shows how we handle shingle roofing from start to finish.
We know you've got questions before you commit. Here's the straight talk on shingle roofing from our crew — no fluff, just facts from 19 years on North Bay roofs.
With proper installation and venting, architectural shingles from Malarkey or CertainTeed last 25 to 30 years in our climate. We've seen 30-year-old roofs still holding strong on homes near the Novato Creek corridor. Our 25-year workmanship warranty covers every replacement we do.
Pricing depends on roof size, slope, layers to remove, and material grade. A typical 2,000-square-foot home runs between $8,000 and $15,000 for architectural shingles. We give free, itemized estimates — no pressure, just the real number for your house.
We don't recommend it. Adding a second layer hides potential rot and adds weight your structure wasn't designed for. We always tear off the old roof so we can inspect the decking and ensure a solid foundation. It's the right way, and it's how we've done it since 2007.
Yes — we're storm damage specialists. If wind or hail hit your roof in Novato, we'll help you document the damage, work with your adjuster, and get the claim moving fast. We've helped homeowners on Grant Avenue and throughout the North Bay navigate the process smoothly.
We install Malarkey, CertainTeed, GAF, Owens Corning, IKO, and Atlas. Each has distinct warranties and wind ratings. We'll walk you through the differences for your home — no upsell, just the best match for your budget and the weather here.
Most residential tear-offs and replacements finish in 2 to 4 days, depending on size and complexity. We schedule around weather windows and keep you updated daily. A typical Novato home with a straightforward pitch is usually done in three days.
Three-tab shingles are flat, lighter, and more budget-friendly — think of them as the entry-level option. Architectural shingles are thicker, have a dimensional look, and carry longer warranties. For most North Bay homes, we recommend architectural for durability and curb appeal.

North Bay Roofing Co. replaced our 22-year-old shingle roof in two days flat. The crew was respectful of our landscaping, cleaned up every nail, and the GAF system they installed looks incredible. The price was fair and they filed the permit without us having to chase it. Will absolutely call them again.
After a winter storm tore off two sections of our flashing, North Bay Roofing Co. was on-site within 24 hours. They tarped the exposed decking that same afternoon, walked us through the insurance claim process, and had the permanent repair done by end of week. Honest estimates, no upsell pressure.
I called for a pre-purchase inspection on a home in Petaluma. The inspector found two soft spots the listing agent hadn't mentioned, documented everything with photos, and gave me a written repair estimate I could use in negotiations. Saved me thousands.
