When Are Certificates Required?

Roofing icon

Re-roofing certificates are required to replace existing roofing tiles and associated roofing material only. If the work includes roof framing or any structural elements, you will need a Building Permit instead of re-roofing certificate.

Insulation certificates are required to replace existing insulation or install insulation only (e.g., at older homes that were originally constructed without any insulation, but required by current Building Code, Section 105).

EXEMPTION: If you have a Building Permit for a project that already includes re-roofing or insulation work, a separate certificate is NOT required.

Who Can Be Issued a Certificate?

  1. Contractors who are licensed by the State of California with a classification appropriate for the work that will be performed and have a current Business Tax Certificate.
  2. Owners of a building or their legal representative.

How to Request a Certificate

PLEASE NOTE: A Re-roof Certificate is for a single structure only. For multiple structures, you must apply for separate re-roofing certificates.
