Mill Valley Voices
North Bay Roofing Co. replaced our old roof on Sycamore Avenue in Mill Valley last spring. They used Malarkey shingles, and the whole crew was respectful of our property. We’ve had zero issues since. 4.9 stars is no joke.
— T. M.
After a storm damaged our roof near Old Mill Park, we called North Bay Roofing Co. They handled the insurance paperwork and had a new CertainTeed roof on within a week. Professional from start to finish.
— L. R.
We needed a full roof replacement on our home in the Strawberry neighborhood. North Bay Roofing Co. walked us through every step, used GAF materials, and finished ahead of schedule. Highly recommend them to any Mill Valley homeowner.
— K. S.
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.
