Asphalt Shingle Roofing Costs

For a typical 1,800-square-foot home in Mill Valley, asphalt shingle replacement runs between $7,200 and $14,400. Architectural shingles cost more than 3-tab but last 30 years instead of 20. We install CertainTeed Landmark and GAF Timberline—both handle coastal fog and winter rain well.

Your roof takes the brunt of Mill Valley's coastal fog, heavy rain, and summer sun. We install modified bitumen systems that handle these conditions without cracking or leaking. Expect a 20-30 year lifespan with proper maintenance.

Superior Durability

Tear Resistant

Our modified bitumen membranes resist punctures and tears from falling branches and foot traffic. That means fewer repairs after storm season. We use SBS-modified asphalt that flexes with your home's natural movement.

Waterproof Protection

Every seam is hot-air welded to create a monolithic waterproof barrier. No gaps, no lifting, no leaks. This system outperforms traditional built-up roofing in Mill Valley's extended rainy season from November through March.

Energy-Efficient

White or light-colored modified membranes reflect up to 80% of solar radiation. Your attic stays cooler in summer, reducing AC costs by 15-25%. That's a measurable savings on your monthly PG&E bill.

Why Choose Modified Roofing

Quality Material

We source only GAF and CertainTeed modified bitumen rolls with 20-year manufacturer warranties. Each roll is inspected for thickness and uniformity before installation. No seconds, no closeouts.

Fully Insured

Millvalley Roofing carries $2 million in general liability and full workers' compensation insurance. We provide certificates before any work begins. Your home and family are protected from day one.

Guarantee

Every modified bitumen roof comes with a 10-year workmanship guarantee. If a seam fails or a blister appears, we fix it at no cost to you. That's our promise in writing.
