Roof replacement and repair in Altadena
A Los Angeles County planning profile reports that almost 90 percent of Altadena's housing units were built before 1979 and that single-family homes dominate. Altadena Heritage notes that a building boom after World War II took up most of the community's remaining open land.
A Los Angeles Times analysis found that only 21 percent of Altadena properties inside the fire perimeter were in a mapped Very High Fire Hazard Severity Zone at the time. A fire-resistant roof is worth having whichever side of a map line a home is on.
Roofing permits in Altadena
Altadena is not a city, so building permits come from Los Angeles County Public Works, Building and Safety Division, not from Pasadena or Los Angeles. The county runs an Altadena One-Stop Permit Center at 464 W. Woodbury Road, Suite 210, for rebuilding. We work from your approved plans and meet the county inspector for the roof.

I lost my home in the Eaton Fire. Can you do the roof alone, or the whole house?
Either. We are general builders as well as roofers, so we can build the house and its roof, or install the roof on a home another builder is framing. Call 818-741-5451 and tell us where you are in the process.
