How to read this

The Contractors State License Board lists complaints it has sent for legal action, citations it has issued, and warning letters. A complaint or accusation is an allegation, not a finding. A citation is the board's finding that a rule was broken; the contractor can appeal it. Complaints closed in the contractor's favor are never listed. Most contractors have no items.

  • Open case: not provenSep 21, 2026 · Case N A 2025 17458

    The board's investigators sent this complaint for legal action on Sep 21, 2026. A complaint is an allegation. Nothing is proven yet.

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.

What to ask before you hire

About Diamond Ridge Roofing Systems

  • Do not hire until the state shows the license as active.
  • Ask what the warranty covers and for how long, in writing.

Worth asking any roofing contractor

  • Can you show me proof of liability insurance and your bond?
  • 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?
