Product Lineup
We’re proud to carry CertainTeed—a brand we’ve trusted for years on homes across Novato, from the Hamilton neighborhood to downtown. Here are three collections we install regularly, each built to handle North Bay weather.
Our go-to asphalt shingle for residential roofs. It’s durable with a classic look, and we’ve used it on scores of projects in Novato’s Pacheco Valle and San Marin. Comes with CertainTeed’s SureStart™ warranty.
A premium shingle that mimics the look of slate or wood shakes. Perfect for custom homes in the Ignacio area or any house where curb appeal matters. We installed it last year on a home on Grant Avenue.
A high-end composite slate shingle that’s lightweight and fire-resistant. Great for historic-style homes in Old Town Novato or commercial roofs needing a slate look without the weight.

Customer Voice
We had a leak after a big storm last winter, and North Bay Roofing Co. showed up the next day. They recommended CertainTeed Landmark shingles for our house near Grant Ave, and the workmanship is solid — no more worries when the rain hits.
— The Millers, Novato
I run a small commercial building on Redwood Blvd, and North Bay Roofing Co. handled our CertainTeed Flintlastic system. Clean install, no mess, and they even helped with the insurance paperwork after some wind damage. Real pros who know their materials.

Verified Reviews
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.
