Roofing in Claremont.
Roofing in Claremont — the City of Trees — means working under one of the heaviest tree canopies in the region, on historic Craftsman and college-town homes that take real care.
What Claremont roofs are up against.
Claremont earns its City of Trees name, and that canopy defines its roofs. Towering, mature trees shade the streets and the historic Craftsman and Spanish homes near the Colleges and the Village, dropping a steady, heavy load of leaves and seeds into valleys and gutters and keeping shaded north slopes damp enough to grow moss. The east-Valley summers are hot and dry, baking the exposed slopes, and the northern edge of town runs up toward the foothills and their fire exposure. Many Claremont homes are older, with original or period-appropriate roofs — clay tile on the Spanish houses, composition on the Craftsman bungalows — where preservation of character matters. It is careful, debris-conscious roofing on homes that people take pride in.

What a Claremont roof job looks like with us.
In Claremont we plan around the trees — keeping valleys clear and drainage working — and re-roof to suit the home: quality composition and rebuilt flashing on the Craftsman houses, lift-and-relay on the Spanish tile.

Common questions from Claremont homeowners.
The trees drop so much debris my roof keeps clogging — can you help?
Yes — heavy tree debris is the defining Claremont roof problem. We clear and re-detail the valleys and drainage, and on a re-roof we build in details that handle the constant leaf load so it does not pond and back up under the roof.
Do you work on older and historic Claremont homes?
Yes — much of our Claremont work is on Craftsman and Spanish period homes. We preserve the look and detailing of the house and rebuild the flashing these older roofs always need.
Is moss on my shaded roof a problem?
It can be — moss and trapped damp on shaded north slopes hold moisture against the roof and shorten its life. We clear it, fix the underlying drainage, and on a re-roof set the slope up to shed and dry properly.

Roofing codes & requirements in Claremont
Energy / cool roof (Title 24)
Claremont sits in California Energy Commission Climate Zone 9. Under Title 24, Part 6, a low-slope or flat roof here must use a cool-roof product (aged solar reflectance of at least 0.63 and thermal emittance of at least 0.75 — roughly SRI 75) when you replace 50% or more of the roof or about 1,000 sq ft or more. Steep-slope (pitched) residential roofs in Climate Zone 9 are exempt from the cool-roof requirement, so standard shingle or tile is fine. Small like-for-like repairs generally don't trigger it. See the California Energy Commission standards and the CRRC directory for rated products.
Fire — foothill parcels
Claremont's northern foothill neighborhoods near the San Gabriel Mountains and the Angeles National Forest are in a Very High Fire Hazard Severity Zone (CAL FIRE's 2025 map), where Chapter 7A requires a Class A roof assembly and ember-resistant construction; the flatter southern city isn't. You can check any parcel on the CAL FIRE hazard-zone viewer.
Decking / sheathing
Many older Claremont homes were built with spaced 1×6 “skip” sheathing under the original roof. For a modern shingle or tile system — and for a Class A assembly — that decking often has to be overlaid with solid sheathing, and any rotted boards replaced. We confirm exactly what your roof needs with a deck inspection at tear-off, not a guess.
Color & materials
Roof color isn't regulated by code. Where a cool roof is required you need a CRRC-rated product that meets the SRI — and those come in a wide range of colors, not just white. On a Pasadena landmark or historic-district property, the design review may also weigh in on material and color.

Common Claremont roofing-code questions
Does my Claremont roof need to be Title 24 cool-roof compliant?
Only on flat or low-slope sections. Claremont is in Climate Zone 9, so Title 24 requires a cool roof (about SRI 75) when you replace 50%+ of a low-slope roof, but steep-slope shingle and tile roofs are exempt here.
Is Claremont in a fire zone that requires a Class A roof?
It depends on your parcel. Claremont's hillside/foothill properties are in a Very High Fire Hazard Severity Zone and need a Class A assembly with ember-resistant details; flatter parcels usually don't. We check the CAL FIRE map for you.
Will my old spaced sheathing need to be re-decked?
Sometimes. Older Claremont homes often have spaced 1×6 sheathing; a modern shingle or tile system (and a Class A assembly) may need solid sheathing over it. A deck inspection at tear-off tells us for sure.
Financing available for qualified Claremont homeowners
You don't have to pay for a roof all at once: financing is available for qualified homeowners, subject to qualification — written itemized pricing first, financing second, never any pressure. And because Title 24 cool-roof products are qualifying energy improvements, a Claremont re-roof that needs one may also qualify for PACE-style energy financing — ask us and we'll confirm what applies to your property.
