Local Roofing Notes
Sonoma's historic charm means many homes have older roof designs that need careful handling. We've worked on Spanish-style tiles and classic comp shingles across the Plaza and Springs neighborhoods. Our 19 years of local experience help us spot issues like water damage before they spread. We use Malarkey and CertainTeed materials that stand up to the valley's hot summers and foggy mornings.
Sonoma Voices
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.

Permit pulled, inspection passed first try, written workmanship warranty issued.
Recent project in Hamilton: Spanish tile — the original cedar shake had delaminated and was letting light through in three spots.
Materials: Boral Saxony 600 Slate tile
Job finished in two days with full debris haul-off.
Recent project in San Marin: Craftsman bungalow — UV degradation had cracked the tile underlayment and water was tracking along the battens.
