Roof Repair and Replacement in Ventura County
Ventura County has three roofing climates within a short drive: the coastal plain around Oxnard and Ventura, the inland valleys of Simi Valley, Thousand Oaks and Moorpark, and the Ojai Valley. Overhead Roofing repairs and replaces roofs across all three, including emergency roof repair after storms.

Three climate zones
On a reroof, the cool roof rule depends on which of three climate zones the house is in.
Oxnard, Port Hueneme, Ventura, Camarillo, El Rio, Channel Islands Beach
Simi Valley, Thousand Oaks, Moorpark, Fillmore, Santa Paula, Bell Canyon, Casa Conejo, Casitas Springs
Central Ojai
Applies when more than half of the roof is replaced. * Unless one of the code’s exceptions applies. Source: California Energy Commission, 2025 Energy Code and building climate zone map.
The Ojai Valley straddles zone 9 and zone 16 on the Energy Commission map. Central Ojai falls in zone 16, while parts of Mira Monte fall in zone 9, so here the exact address decides.
The 2025 fire maps hit the inland cities hardest
CAL FIRE released new Fire Hazard Severity Zone maps for Ventura County on March 10, 2025. Moorpark, Simi Valley and Thousand Oaks have the most acres rated Very High, Very High acreage in Ojai more than tripled, and unincorporated Ventura County now has more than 31,000 Very High acres, five times the 2011 figure.
For a homeowner in those areas the practical result is simple: a replacement roof must be Class A rated, and ember-resistant vents and details are part of the job.
Coastal roofs
From Oxnard to Ventura, salt air corrodes nails, flashing and metal vents before it damages tile or shingles. On coastal roofs we check every flashing joint and use corrosion-resistant fasteners and metals.
Permits in unincorporated communities
Bell Canyon, Casa Conejo, El Rio, Channel Islands Beach and Casitas Springs are unincorporated, so permits come from the Ventura County Resource Management Agency, Building and Safety. The cities issue their own permits.
