Transparent Roof Pricing
We know roof pricing can feel like a guessing game. That's why we break down every cost upfront—materials, labor, permits—so you know exactly what you're paying for. No surprises, just fair prices for quality work.
Roof replacement starts around $7,500 for asphalt shingles on a typical San Anselmo home, with premium materials like Malarkey Legacy adding durability and curb appeal.
Repairs range from $300 to $1,200 depending on the damage—our team often patches storm-damaged areas near Sir Francis Drake Boulevard within 24 hours.
Flat roof replacements (common on mid-century homes in Sleepy Hollow) use TPO or PVC membranes, typically $8–$12 per square foot installed.
All estimates are free and customized to your roof. Final pricing depends on size, slope, materials, and accessibility. We'll walk through each line item before any work begins.
Local Roofing Notes
We've worked on dozens of homes in San Anselmo, from the historic Victorians near San Anselmo Avenue to the hillside ranches off Butterfield Road. Our crew knows how the fog and coastal winds hit different neighborhoods, and we recommend Malarkey shingles for their impact resistance in Marin's microclimates. Whether you need a full replacement on a Red Hill home or storm damage repair after a wet season, we bring 19 years of local know-how to every job.
San Anselmo Voices
We had North Bay Roofing Co. replace our old roof on Sir Francis Drake Blvd last spring. They used Malarkey shingles and the whole crew was professional from start to finish. Our house stayed dry through that big storm in December. 5 stars.
After water damage from a leak in our Ross Valley home, we called North Bay Roofing Co. for emergency service. They were here within hours, fixed the damaged section, and helped us with the insurance claim. We've recommended them to three neighbors already.
North Bay Roofing Co. did a full tear-off and replacement on our house in the Sleepy Hollow neighborhood. They used CertainTeed shingles and the workmanship warranty gave us peace of mind. The crew even cleaned up every scrap of debris. Highly recommend.
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.
