Typical Roof Repair & Replacement Costs in Mill Valley
Pricing depends on roof size, slope, access, existing layers, and material choice. In the Bay Area, labor and permitting can also influence the total. The best way to get an accurate number is a site inspection.
- Repairs: targeted fixes for leaks, flashing, and damaged shingles or membrane areas.
- Replacement: full tear-off (or selective removal) plus new underlayment and roofing system.
- Sheathing: if wood decking is compromised, replacement may be recommended for long-term durability.
Repair vs. Replace: How to Decide
Choose repair when damage is localized and the roof has life left. Choose replacement when the roof is near end-of-life, has widespread issues, or repeated leaks.
- Roof age approaching typical lifespan for your material
- Multiple leak points or recurring repairs
- Widespread granule loss, curling, cracking, or membrane failure
- Visible sagging or soft decking
