Roofing in Pasadena, for us, means replacing, reroofing and building new roofs, each planned around the layer most likely to give out first. The city sits in climate zone 9 and runs its own permit counter, which shapes every scope we write here.
The houses under Pasadena roofs
ACS 2020-2024 data gives Pasadena a median year built of 1961 and about 10,423 owner-occupied single-family homes (U.S. Census Bureau). Those figures describe the city as a whole, so they say nothing about any single district.
What they do suggest is where to look at tear-off. Deck boards, flashing at chimneys and walls, and the underlayment beneath the covering are the parts that have had the longest exposure, and we open every scope with them.
Climate zone 9 and the reroof
Pasadena is in climate zone 9 (California Energy Commission zone list). The zone number feeds the state cool roof test, which a reroof meets when the replaced share passes 50 percent. Zone 9 appears in both slope tables, so a steep roof and a low roof each have a target, SRI 16 and SRI 75 at the simplest (California Energy Commission, 2022 Standards).
The zone also appears in the list for the no-ducts exception, which a steep-slope house with a duct-free attic can claim.
Permits and fire zones in Pasadena
The Permit Center, part of Planning and Community Development, takes Pasadena applications. Inspection is the Building and Safety Division's job. Ask what a reroof at your address requires.
A City of Pasadena council report of 21 Jul 2025 says parts of the city are mapped Moderate, High or Very High for fire. Check the address on the CAL FIRE map viewer.
Which jobs we take in Pasadena
Replacements, reroofs and new roofs are the work we plan around, from tile and shingle to metal and flat roofs.
Pasadena roofing, answered
What is the richest part of Pasadena, CA?
The figures we use are for the city as a whole, so they cannot rank its neighborhoods by wealth. For a roof, the useful facts belong to the address: the age of the house, the fire zone and the permit path.
What roof types are common in Pasadena?
Tile, shingle, metal and flat roofs are all installed here. For a particular house, weight, fire class and the cool roof test decide which one is allowed, and the deck decides which one is sound.
What does Pasadena's climate zone change about a reroof?
Pasadena is placed in zone 9, so past 50 percent of a single-family roof the state cool roof test applies, with a target for steep slopes and one for low slopes (California Energy Commission, 2022 Standards).
