Is there a Marin price per roof?

No one publishes a single Marin price. According to the 2025 Cost vs. Value report, a typical midrange reroof of about 3,000 square feet in the San Francisco metro runs roughly $38,000 in asphalt shingles, or roughly $65,000 in metal. Your roof's size, pitch, material and access will move the number; a free written estimate is the only figure that applies to your home. Marin's terrain, trees and access can push an individual bid around that frame.

What raises a Marin bid

  • Moss and decking under redwoods and oaks: sheathing rot shows up only after tear-off. See dry rot and decking in Marin.
  • Hillside access in Mill Valley, Sausalito, Tiburon and the Ross Valley: staging and hauling take longer.
  • Salt air near the water: coated or stainless fasteners and flashing.
  • Old layers and shake: a full tear-off, and Class A materials where the fire rules apply.
  • Material choice: metal and tile cost more up front; see metal roofs in Marin.

Why do Marin quotes include decking allowances?

Moss and moisture under trees can rot sheathing, which only shows once the old roof is off.

Do hillside homes cost more?

Usually, because staging and hauling take longer.

Can you give me a Marin price over the phone?

Not a reliable one. Size, layers, decking and access vary too much; the roofer's written estimate is free.
