Tile Roofs in Granite Hills

Granite Hills has an old housing stock for this region. 79.6% of its 1,182 homes were built before 1980 and 27.3% before 1960. The median year built is 1967. Owners hold 87.5% of homes and the median value is $974,500.

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 (EL CAJON 2.3ENE, 2.0 km away).

Housing and roofs

A 1967 median means some roofs here may have been replaced. A home of that age may carry a roof of tile, shingle or something else. The Census data does not show roof type. Where tile is on the roof, a lift and relay of old tile can be a middle path. Ask the bidder to state a breakage allowance and the price of replacements.

Older frames may also hold less weight. If a bidder proposes a switch from lightweight roofing to tile, ask for a structural check first.

Fire exposure

CAL FIRE maps 52.3% of the area in a very high zone and 60.7% in any zone. About half the community is therefore in the top class. That is a planning label for a map cell, not a verdict on a house. The county's Consolidated WUI Code applies during plan review, so ask which assembly is proposed.

Climate zone 10 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.

The nearest NOAA station records 13.79 inches of rain a year. With older homes, flashing at walls and chimneys may be an early failure point, ahead of the tile itself.

Homes past the 1980 mark

By the shares in the table, about 940 of 1,182 homes pre-date 1980 and about 1,030 are lived in by their owners. Treat both as rounded estimates. A 1980 cutoff matters because a roof installed that year, if never replaced, is now over 45 years old.

Price ranges

Two public sources frame the price. Fixr, dated Jan 31, 2025: clay $9 to $20, concrete $3 to $20 per square foot, with labor treatment unclear; underlayment $0.50 to $2; removal $0.50 to $1.50. RoofingCalc, dated Oct 10, 2024: $29,000 to $51,000 for a 2,000 square foot roof. Treat both as estimates. More in the cost guide.

Permits

The county handles permits for Granite Hills. From the Building Division page:

• 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.
• 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.
• Plans are checked against California Building Standards, county amendments, the Consolidated Fire Code and the Consolidated WUI Code.

That page lists no re-roof rule or fee. Many cities require a permit for a re-roof. Call or visit the Permit Center, or check online, before work begins.

Checklist

• Three bids, one scope.
• A CSLB license lookup for each.
• The CRRC listing for the tile.
• The county's answer on assembly and cool roof rules.
• A signed-off final inspection on file.
