## Oxnard homes by the decade they were built

Oxnard has far more old housing than its inland neighbors. The Census Bureau's 2020-2024 American Community Survey puts the median year built at 1977, and about 18 percent of the city's homes were built before 1960, against about 5 percent in Thousand Oaks or Camarillo:

| Built | Share of Oxnard housing units |
| --- | --- |
| Before 1960 | about 18% |
| 1960s | about 18% |
| 1970s | about 21% |
| 1980 to 1999 | about 20% |
| 2000 or later | about 23% |

A house from the 1950s or 1960s has usually had several roofs. What matters for the next one is what is left underneath: old layers, patched decking, flashing from earlier jobs, and that only shows on the roof itself.

## Tear-off or roof-over on an older Oxnard house?

Laying new shingles over old ones costs less up front, but the 2025 California Residential Code limits when it is allowed. Under the exceptions to Section R908.4, a new covering may not go over an existing roof when:

- the existing roof is water soaked or too deteriorated to serve as a base;
- the existing covering is slate, clay or cement tile, or asbestos-cement;
- the roof already has two or more layers of any covering.

On the oldest Oxnard houses the third rule often settles it. A full replacement removes every layer down to the deck (Section R908.3), which also lets the decking be checked and repaired before the new roof goes on. When tile comes off and goes back on, cracked or broken tiles may not be reinstalled, and rusted or damaged flashing, vents and edgings must be replaced (Section R908.5).

## Coastal weather: mild summers, wet winters, salt air

The NOAA station at Oxnard's Ventura County airport shows how mild the climate is: summer highs average 72°F and the temperature reaches 90°F on only two or three days a year. The normal rainfall is about 13 inches a year, and about 10.5 of those inches fall from December through March.

Heat is rarely what wears out an Oxnard roof. Steady sun, the damp marine air and, closer to the beach, salt are harder on the metal parts: flashing, vent caps, fasteners and drip edges corrode while the shingles or tiles still look fine. When you compare bids for a home near the coast, ask which flashing and fastener materials each roofer plans to use and whether the roofing manufacturer has guidance for coastal exposure.

Repairs we handle include rusted or failed flashing, leaks at vents, pipes and other roof penetrations, cracked or displaced tiles, damaged shingles, and flat sections where water stands after a storm. The [roof repair page](https://infinity-roofers.com/roofing-services/roof-repair/) explains how a repair is scoped; the [roof replacement page](https://infinity-roofers.com/roofing-services/roof-replacement/) covers a full tear-off, and roofs for new buildings are on the [new roof installation page](https://infinity-roofers.com/roofing-services/new-roof-installation/).

## Most of Oxnard is outside the fire hazard zones

Wildfire roofing rules reach few Oxnard homes. On the State Fire Marshal's 2025 Fire Hazard Severity Zone map, nothing inside the city boundary is rated Very High. About 4 percent of the area inside that boundary is High and about 1 percent Moderate; the rest is non-wildland land or water.

For a home outside the zones, the state minimum is a Class C fire-rated covering for a new roof, for a reroof of more than half the roof within a year, and for repaired sections (California Residential Code R902.1.2).

A home inside one of the small High areas follows the California Wildland-Urban Interface Code instead, which covers High and Very High zones in local responsibility areas such as Oxnard and requires a Class A roof assembly and ember-resistant details. That code's stated purpose does not include Moderate zones in local responsibility areas, so for an address in the small Moderate area, ask the city's Building and Engineering division which roof rule applies. Check your address in the [CAL FIRE Fire Hazard Severity Zone viewer](https://experience.arcgis.com/experience/5065c998b4b0462f9ec3c6c226c610a9).

## Getting a reroof permit in Oxnard

The City of Oxnard's Building and Engineering division lists re-roofing among its over-the-counter permits, the category the city uses for simpler projects; they can be obtained online or at the city's Service Center. When a project does need plan review, the city's Permit Fast Track program sets up a one-hour plan review meeting by appointment, with no additional fees: one track for residential projects and one for commercial ones.

Not every home around Oxnard is inside the city. El Rio, Nyeland Acres and Channel Islands Beach are unincorporated communities (each is a census-designated place), so roofs there are permitted by the County of Ventura's Building and Safety Division. Port Hueneme, next door, is a separate city, so its permits are not Oxnard's. The city's interactive zoning map lets you verify which jurisdiction your parcel is in before work starts.

## Flat roofs, rentals and commercial buildings in Oxnard

About 46 percent of Oxnard's occupied homes are rented, and about 30 percent of its housing units sit in buildings with two or more units. Apartment and commercial buildings often have flat or low-slope roofs, where seams, drains and standing water decide how long the roof lasts.

The Oxnard ZIP codes 93030, 93033 and 93035 are in Building Climate Zone 6, and the climate zone sets the cool-roof rule for houses. On a single-family home, when more than half of a low-slope roof is replaced, California's 2025 Energy Code requires an aged solar reflectance of at least 0.63 and a thermal emittance of at least 0.75, or SRI 75, but no added roof insulation in this zone; a pitched roof on a house has no cool-roof minimum in Zone 6 (Section 150.2(b)1I, the rule for existing single-family homes).

Apartment and commercial buildings follow other sections of the Energy Code, so a bid for one of those roofs should state which requirement it was written to.

For businesses and property owners we repair TPO and EPDM membranes and flat commercial roofs: seam separation, punctures, ponding water and damaged membranes. See the [commercial roof repair page](https://infinity-roofers.com/roofing-services/commercial-roof-repair/) for the details.
