Cost and timing

Permit value (not a price)

Their typical permit lists $15,500 (half list more, half less)

That is the figure written on the permit form, which can be far from what you pay. A typical roof of theirs is about 15 squares (1,500 sq ft). What roofing jobs cost in San Francisco.

Permit timeline

Across San Francisco, a roofing permit stays open about 28 days, from permit to final inspection

This is not how long the crew works at your home: most of it is waiting for the inspection. Ask them how many days the work takes. The permit itself is usually issued the same day. How long roofing jobs take.

Worth asking any roofing contractor

  • Will you tear off the old roof or lay the new one over it?
  • What do you charge to replace rotted roof boards, per sheet, if you find any?
  • Who pulls the permit, and who meets the inspector?
