Re-roofing Guidelines

Updated April 6, 2020

If you are planning to reroof your home, be sure your plans conform with the City's re-roofing guidelines for single-family homes and that you obtain a building permit. The City requires homeowners to reroof their homes with material that has at least a 30-year warranty.

Roof material with a 30-year warranty is superior in quality and appearance to material with only a 20-year warranty. The City's guidelines were adopted to protect homes from fire and weather damage while enhancing the property values and appearance of the community.

Re-roofing Application Process

When applying for re-roofing approval, homeowners must submit to the City a completed application and a sample of the proposed material to be used for re-roofing, if it has not previously been approved by the City. All roofing materials and colors must be approved by the City's Community Development Department. A building permit from the City is also required. If a contractor is re-roofing your home, ask to see the building permit prior to the start of any work.

As part of the permit process, the City's Building and Safety Division will inspect the roofing once it has been replaced to determine if the proper roofing materials were used and correctly installed. Reroofing with clay, concrete or metal tiles may require engineering review by the City's Building and Safety Plan Checker.

Final Inspection Before Full Payment to Contractor

The City's final inspection of the roof should be done on your home before full payment is made to your contractor. The permit process reduces the chances of having an unlicensed contractor install substandard roofing materials.

Approved Re-roofing Replacement Materials

Under City ordinance, the following materials have been approved for replacement roofing: heavy-butted asphalt shingles (also known as "dimensional" fiberglass shingles), synthetic shake or synthetic tile, concrete tile, clay tile or metal-coated material which simulates the appearance of clay or concrete. The installation of three-tab asphalt shingles is not permitted in Cerritos. All materials are required to have a minimum Class-C fire retardant rating and a minimum 30-year warranty.
