Tile Roofs in Bonita

Bonita has 4,474 housing units and a median home value of $962,800. It has the opposite fire profile of its neighbors in this batch: only 1.0% of the area is in a very high zone, and 25.6% in any zone.

Key figures

Sources: U.S. Census Bureau, ACS 2020-2024 5-year; CAL FIRE Fire Hazard Severity Zones (estimate by overlay of the place area); NOAA 1991-2020 normals (CHULA VISTA 6.3E, 4.8 km away).

Housing and roofs

The median build year is 1976, 68.6% of homes pre-date 1980 and 14.8% pre-date 1960. 76.0% are owner occupied, so about a quarter are rentals, where a landlord decides on the roof. Older Bonita homes may have had one or two re-roofs, and tile is common in Spanish and Mediterranean styles across Southern California.

With low fire exposure, the main roof risks are age, sun and the occasional storm. Underlayment is the item to date. If the last re-roof is over 20 years back, ask whether the felt is still flexible.

Fire exposure

Only 1.0% of the area is in a very high zone and 25.6% falls in any mapped zone. Most parcels may sit outside the maps entirely. A parcel in a mapped corner may still face assembly rules, so check your address with the county.

Climate zone 7 and the cool roof rule

The California Energy Commission's 2022 cool roof sheet says requirements for alterations, which include re-roofs, apply in additional climate zones beyond those listed for new homes. Ask the building department which cool roof values apply to your re-roof.

Rainfall at the nearest NOAA station is 12.19 inches a year. Fixr cites about 100 years for clay and 50 for concrete, and those are product figures, not roof system guarantees. A roof system is tile plus underlayment, flashing, ridge mortar or foam and the deck. The weakest part sets the real service life, so ask a bidder to describe each layer and its expected age, and to say which parts they would replace now and which they would leave.

Who owns and how old

In round numbers, 3,400 owner occupied homes out of 4,474, and about 3,070 that pre-date 1980. The Census gives shares, so these are derived estimates. Together they sketch who may be shopping for tile work here and how old their roofs may be.

Price ranges

What the sources say: Fixr (Jan 31, 2025) gives $9 to $20 per square foot for clay and $3 to $20 for concrete, and does not state consistently whether labor is counted. It adds $0.50 to $2 for underlayment and $0.50 to $1.50 for removal. RoofingCalc (Oct 10, 2024) gives $29,000 to $51,000 for a 2,000 square foot tile roof. Local bids will differ. See the cost guide.

Permits

Outside city limits, San Diego County issues building permits. Its Building Division page notes:

• The Permit Center is in Kearny Mesa for questions before and during review.
• Certain structures may be exempt, and the page links a Building Permit Requirements handout.
• Building Services issues permits for homes and commercial buildings in unincorporated areas.
• Accela Citizen Access handles simple permit applications, status checks, inspection booking and fee payment online.

That page lists no fee for re-roofing and no re-roof rule. Many cities require a permit for this work. Verify your case with the county ahead of any contract.

Checklist

• Write down the scope before asking for bids.
• Search each license at cslb.ca.gov.
• Ask what tile brand and CRRC number are proposed.
• Ask the county what rules cover your lot.
• Keep the permit paperwork.
