AA California Roofing is a team of licensed roofers serving Pasadena, CA: we replace and repair asphalt shingle, tile and low-slope roofs, including houses in the city’s landmark and historic districts, and we pull the City of Pasadena permit for the work. We are licensed by the CSLB (#1147688), and a Pasadena homeowner has reviewed our roof replacement on Google.
For a free estimate, book online through our contact page. We are open Sunday to Friday, 8:00 AM to 8:00 PM.
Most Pasadena roof work falls into four kinds of jobs. Each one has a local twist, because so much of the city’s housing is old and so many houses sit in designated districts.
Yes. Re-roofing is not on the City of Pasadena’s list of work exempt from a building permit, so a roof replacement goes through the Building and Safety Division at the Permit Center, 175 North Garfield Avenue. Inspections are booked through the City’s online Inspection Portal.
Three Pasadena details are worth knowing before work starts:
Outside the Central District, Pasadena protects designated historic monuments and landmarks, contributing houses in landmark and historic districts, and properties found eligible in a historic resources survey. Work that may affect one of these needs a Certificate of Appropriateness, reviewed by Design and Historic Preservation staff or by the Historic Preservation Commission.
For roofs, the City’s own definitions do much of the sorting. Re-roofing in a different material that replicates the existing or original roofing is listed as a minor project. If the house is in the Bungalow Heaven, Garfield Heights or Banbury Oaks Landmark District, that district’s conservation plan decides which projects need a certificate.
The City’s Design Guidelines for Historic Districts in Pasadena spell out what reviewers look for on a roof:
| What the guidelines say | What it means for your re-roof |
|---|---|
| Preserve the original roof form; keep the line and slope of the roof as seen from the street (7.17) | The roofline is not raised, flattened or reshaped as part of the job. |
| Preserve the original eave depth; do not cut back rafters or box in exposed rafter tails (7.18) | Craftsman overhangs and rafter tails stay. Rotted tails are repaired; the guidelines suggest a borate treatment or discreet metal caps (7.19). |
| Wood and composition shingles are appropriate for most roofs; tile is replaced with matching material whenever feasible | A Craftsman bungalow can usually take composition (asphalt) shingles. A Spanish Revival tile roof usually stays tile. |
| In general, metal roofs are inappropriate on a historic structure (6.9) | Expect a metal roof proposal on a historic house to meet resistance. |
| A certificate application includes roof plans and physical samples of new materials, roofing included | Plan for the shingle or tile sample and the product sheet to go in with the application. |
Not sure whether your house is listed? The City publishes a database of designated and surveyed properties and a map of its landmark and historic districts on its historic preservation pages. It is the first thing to check during an estimate, because it changes the paperwork and sometimes the material.
Census estimates (American Community Survey, 2020 to 2024) show that 28.6% of Pasadena’s 63,203 housing units were built in 1939 or earlier, and 49.4% before 1960. Detached single-family houses make up 42.7% of units, and buildings with 20 or more units another 26.5%.
Style matters as much as age. The City’s guidelines describe typical Pasadena roof shapes as gabled, cross-gabled and hipped, and list the main house styles with their roofs:
What that means on the roof itself:
Pasadena’s ZIP codes 91101 and 91103 through 91107 are all in Building Climate Zone 9 on the California Energy Commission’s ZIP-code list. Under the 2025 Energy Code, when more than half of a house’s roof is replaced, Zone 9 carries roofing rules that the coastal Zone 6 does not:
| Roof type | Requirement when more than 50% is replaced | How it is commonly met or excused |
|---|---|---|
| Steep-slope (shingle, tile) | Aged solar reflectance of at least 0.20 and thermal emittance of at least 0.75, or an SRI of at least 16 | Not required if the attic has at least R-38 ceiling insulation, a qualifying radiant barrier, no ducts in the attic (a Zone 9 option), R-2 or more continuous insulation at the deck, or a roof weighing at least 25 lb per sq ft |
| Low-slope (flat) | Aged solar reflectance of at least 0.63 and emittance of at least 0.75, or an SRI of at least 75, plus R-14 continuous insulation | Deck insulation can stand in for reflectance (R-24 removes the reflectance minimum in Zone 9). The added insulation is not required over existing R-10 continuous insulation, or over at least R-19 between the rafters in contact with the deck. |
Source: 2025 Building Energy Efficiency Standards, Section 150.2(b)1I for single-family homes. Apartment buildings follow Section 180.2, which applies once more than half the roof, or more than 2,000 square feet, is altered, whichever is less. An attic inspection during the estimate tells us which of these paths fits your house.
The State Fire Marshal’s Local Responsibility Area map for Pasadena (March 24, 2025) shows Very High Fire Hazard Severity Zones across the hills on the city’s west side and in pockets along its northern edge. In a very high zone, state law (Health and Safety Code 13132.7) calls for a Class A roof covering when more than half of the roof is replaced within one year, and for roofing used in repairs. The 2025 California Residential Code also sends roofing in fire hazard zones to the California Wildland-Urban Interface Code.
A Class A rating belongs to a tested roof assembly (ASTM E108 or UL 790), so the product sheet has to show it for the way the roof is built. The Fire Department posts the map on its fire hazard severity zone page.
A homeowner wrote on Google in October 2026: “I had my roof replaced at my home in Pasadena, and Nick was great to work with. The whole experience was smooth, and I’m very happy with the new roof.”
