San Marcos has the newest housing stock of any inland North County city — more than a quarter of its homes were built in the 2000s, most of them in specific-plan communities the city still administers: San Elijo Hills on the southern ridges, the University District and Heart of the City around Cal State San Marcos, San Marcos Creek, and Santa Fe Hills and Paloma on the north side. Those are concrete tile roofs under HOA standards, now 15 to 25 years old. The older core along Mission Road and the 1970s neighborhoods around Lake San Marcos and Twin Oaks Valley are composition shingle and earlier tile.
The city's General Plan Safety Element names the hillsides north of SR-78 in Santa Fe Hills and Twin Oaks Valley, the hillsides south of SR-78 in Barham/Discovery and Questhaven/La Costa Meadows, and areas around Lake San Marcos as Very High Fire Hazard Severity Zones, and notes that late summer and fall are the critical fire months. The May 2014 Cocos Fire started at Village Drive and Twin Oaks Road, burned 1,995 acres, and destroyed 40 structures. The San Marcos Fire Department's own home-hardening guidance tells residents to re-roof with non-combustible materials such as composition, metal, or tile.
Our San Marcos services are tile repairs and early underlayment fixes on the 2000s communities, shake-conversion and shingle re-roofs on the older neighborhoods, Class A fire-zone assemblies on the hillsides, and wind and fire-related insurance claim documentation.
San Marcos at a glance

Housing age: The median home in San Marcos was built in 1994, and about 45% of its 32,255 housing units were built in the 1990s and 2000s (U.S. Census Bureau, 2019–2023 ACS 5-Year Estimates).
ZIP codes served: 92069, 92078
Permits: Re-roofs are permitted and inspected through the City of San Marcos Building Division. We pull the permit and schedule inspections.
Fire hazard zones: Parts of San Marcos are mapped as a Very High Fire Hazard Severity Zone by the California Office of the State Fire Marshal. Inside those zones a re-roof must use a Class A fire-rated roof covering (California Residential Code R902.1.1), and we recommend ember-resistant vents and the other Chapter 7A details whenever vents or eaves are replaced. Check your address on the official fire-zone map.

SAN MARCOS ROOFING FAQ
Is my San Marcos home in a fire hazard zone?
The city's Safety Element maps the hillsides on both sides of SR-78 — Santa Fe Hills, Twin Oaks Valley, Barham/Discovery, Questhaven/La Costa Meadows — and areas around Lake San Marcos as Very High. We check the map for your address and specify a Class A assembly with ember-resistant vents where it applies.
My San Elijo Hills tile roof is 20 years old — what should I expect?
The tile itself has decades left. What we usually find at 20 years is cracked tiles from rooftop work, loose flashings, and the first underlayment problems at valleys and skylights — repairs, not a replacement.
Do you pull permits in San Marcos?
Yes. Re-roofs are permitted through the City of San Marcos Building Division at 1 Civic Center Drive using the city's online portal; we submit the application and schedule the inspections.
How do I choose the best roofing contractor in San Marcos?
Check four things before you sign anything: an active California contractor license you can look up on the CSLB website (ours is CSLB #1149997), a manufacturer certification such as GAF Certified, a real local office (Stone Ranch Construction is at 711 W 17th St, Unit G-2, Costa Mesa, about a drive down the freeway from San Marcos), and a free on-the-roof inspection with a written estimate that names the materials. Then compare bids on the same scope, not the lowest number. Call or text (714) 790-9925 to schedule an inspection in San Marcos.
