Roofing Contractor in Claremont, CA, for Matched Reroofs and Foothill Homes
Close to half of Claremont’s homes were built in the 1950s and 1960s, and when a house is on the Claremont Register or contributes to a historic district, its new roof has to match the old one in appearance, color, and profile. For homeowners hiring a roofing contractor in Claremont, CA, that review comes first, followed by the fire rules in the north Claremont foothills, where the 2003 Grand Prix Fire destroyed homes.

Certificates of Appropriateness for Claremont Register reroofs
Claremont’s Cultural Resources Preservation ordinance covers properties on the City’s Register of Structures of Historic and Architectural Merit and contributors to historic districts. Under the municipal code, work that could significantly affect one of these resources needs a Certificate of Appropriateness, and in general it can’t start until the certificate is approved.
A reroof gets a simpler path. When the reroofing leaves the exterior features unchanged, City staff can approve the certificate, provided the replacement matches the existing or original roofing in appearance, color, profile, and material. Ordinary maintenance and repair that needs no building permit is exempt from the certificate requirement. The same ordinance names deteriorated or ineffective roof waterproofing as a maintenance problem for historic resources, so a leak on a Register property is worth fixing early.
Architectural review outside the Register
In the Historical Claremont (HC) district, a neighborhood of grid streets with tree-lined parkways, all new construction and exterior alterations go through architectural review. Elsewhere, exterior changes to single-family homes in the RS districts go to staff architectural review, and exterior changes to other residential buildings go to the Architectural and Preservation Commission. The City doesn’t spell out whether a like-for-like reroof counts as an exterior change, so we ask Planning before the work is scheduled.
On a matched reroof, we photograph the existing material, color, and profile before tear-off, so the certificate application and the material order describe the same roof.
Permits at City Hall on Harvard Avenue, by email or at the counter
Claremont runs its own Building Division, with a City Building Official and inspectors, at City Hall, 207 Harvard Avenue. Permits are issued Monday through Thursday, 7 a.m. to 5:30 p.m. The City has no online permit portal: as its building permits page explains, projects with plan sets are submitted by email, and permits without plans are issued at the counter.
The whole city, ZIP code 91711, falls in Climate Zone 9. Under the 2025 California Energy Code, replacing more than 50% of a residential steep-slope roof there calls for a product with a Cool Roof Rating Council rating. On a Register property, the new roof has to satisfy both rules at once, the cool roof rating and the match in color and profile, so we check rated products against the existing roof before the certificate application goes in.
North Claremont after the 2003 Grand Prix Fire
The Grand Prix Fire burned through Claremont on October 25 and 26, 2003. By the Claremont Courier’s count, it destroyed 65 homes in and around town: 44 in Palmer Canyon, 14 in Claraboya with 15 more damaged, 4 in Padua Hills, and 3 on Mills Avenue near the Claremont Hills Wilderness Park. In Claraboya, the fire reached Independence Drive, Pomello Drive, Via Espirito Santos, and Base Line Road.
Those foothills are still mapped as fire zones. The City says portions of northern Claremont are in the zone, naming the Wilderness Park and private properties along Mills and Padua. CAL FIRE released the updated map on March 24, 2025, the City Council approved it on July 22, 2025, and the City posts a parcel-based fire zone map.
In a Very High zone, a replacement roof must be Class A. The City’s fire prevention page counts hardening a house against wind-blown embers as one of three factors in whether it survives a wildfire; on the roof, that means ember-resistant vents, closed gaps at eaves and ridges, and valleys and gutters kept clear. LA County Fire, which covers Claremont by contract, begins defensible space inspections in High and Very High zones on May 1 and clears brush in the Wilderness Park each June.

Claremont questions on certificates, permits, and fire zones
Do I need a Certificate of Appropriateness to reroof my Claremont house?
You need one if the house is on the Claremont Register or contributes to a historic district. For those properties, a reroof that doesn’t change exterior features is a staff-level certificate, and the new roofing must match the existing or original in appearance, color, profile, and material. Ordinary repairs that need no building permit are exempt, and covered work generally can’t begin before approval.
Where do I get a reroof permit in Claremont?
Permits come from the City’s Building Division at City Hall, 207 Harvard Avenue, Monday through Thursday, 7 a.m. to 5:30 p.m. There is no online portal, so plan sets go in by email and permits without plans are issued at the counter. Call (909) 399-5471 to confirm what your reroof needs.
Which parts of Claremont are in the fire hazard zone?
The zone covers portions of northern Claremont, including the Claremont Hills Wilderness Park and private properties along Mills and Padua, and the City Council approved the 2025 map on July 22, 2025. Look up your parcel on the City’s parcel-based map. A Very High address needs a Class A replacement roof.
Can a historic Claremont roof meet the cool roof rule too?
It has to when more than half the roof is replaced. Claremont is in Climate Zone 9, where a residential steep-slope reroof past that point needs a CRRC-rated product. On a Register property, that product also has to match the existing roof’s appearance, color, and profile, so we narrow the options to rated products that match before the certificate application.
Do you do torch-down roofing in Claremont?
We do, on low-slope roofs: flat sections, additions, and porch roofs with too little pitch for shingles or tile. Torch-down uses modified bitumen sheets fused with heat at the seams and finished with a mineral cap sheet. A residential low-slope reroof over half the roof also has to meet cool roof requirements.
