Tile Roofs in Lake San Marcos

Lake San Marcos has 2,117 housing units, a median build year of 1979 and a median home value of $917,000. 79.0% of homes are owner occupied. About half the area, 51.6%, is in a very high fire hazard 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 (SAN MARCOS 3.3 WSW, 1.8 km away).

Housing and roofs

The housing stock splits almost evenly around 1980: 54.0% were built before it and the rest after. Only 5.1% were built before 1960. A roof from the late 1970s may be on its second round, and a roof from the 1980s may be at the first replacement. Where that roof is tile, the layer under it is a fair question.

Tile is common in Spanish and Mediterranean styles across Southern California, and homes in those styles may be found here.

Fire exposure

CAL FIRE maps 51.6% of the area in a very high zone and 67.6% in any zone. Read it as a planning map that covers the community, not each lot. The county's Consolidated WUI Code is part of plan review, and a bidder should be able to name the assembly they would use.

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 13.2 inches of rain a year, and it sits 1.8 km from the place. Check the lowest course of tile and the drip edge when you inspect.

Roofs old enough to review

Applied to 2,117 units, the shares give about 1,140 homes built before 1980 and about 1,670 that owners occupy. These are rounded estimates. They show how many roofs may be old enough to review, whatever material they use.

Price ranges

Fixr (Jan 31, 2025) and RoofingCalc (Oct 10, 2024) are the two price sources used on this site. Fixr: clay $9 to $20, concrete $3 to $20 per square foot, labor basis unclear, plus $0.50 to $2 underlayment and $0.50 to $1.50 removal. RoofingCalc: $29,000 to $51,000 for 2,000 square feet. Neither is a quote for this community. See the cost guide.

Permits

Lake San Marcos is outside city limits, so the county Building Division is the office. It states:

• 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.
• The Permit Center is in Kearny Mesa for questions before and during review.
• Plans are checked against California Building Standards, county amendments, the Consolidated Fire Code and the Consolidated WUI Code.
• Accela Citizen Access handles simple permit applications, status checks, inspection booking and fee payment online.

No re-roof details or fees are listed. Many cities require a permit for a re-roof, so check with the county before a crew mobilizes.

Checklist

• Pick one written scope and send it to three bidders.
• Confirm each license at cslb.ca.gov.
• Get the tile's CRRC and fire listing in writing.
• Ask the county which rules apply.
• Store the inspection sign-off.

Everything above is community-wide. Verify your parcel.
