What drives roof replacement cost
- Roof size (“squares”): Roofers price in 100 sq ft “squares.” A bigger or multi-story roof means more material and labor.
- Material: Asphalt is cheapest; metal, tile, and shake cost two to four times as much but last far longer.
- Pitch & complexity: Steep, cut-up roofs with lots of valleys, dormers, and skylights are slower and riskier to work on.
- Tear-off & decking: Stripping old layers and replacing rotted plywood decking adds labor and disposal cost.
- Permits & labor rates: Local permit fees and crew wages vary a lot by metro — the single biggest reason the same roof costs more in one city than another.
San Mateo cost factors
The San Francisco Bay Area has some of the highest contractor labor rates in the country, along with strict California permitting, energy codes, and seismic requirements. The mild climate is easy on equipment, but demand and the cost of living keep nearly every home project well above the national average.
