Roofing + Solar in
San Marcos, CA
San Marcos was built in waves — a 1960s lake community, boom-decade tract streets, San Elijo Hills from 2002. Which wave your street belongs to decides whether solar goes on now or after a re-roof.
Is San Marcos a good place to re-roof and go solar together?
Yes — and in San Marcos it comes down to your street's decade. Lake San Marcos was platted after the lake was enlarged in 1962; San Elijo Hills broke ground in 2002. A 1970s covering rarely has the ten to fifteen years a 25-year array needs above it; a 2000s one usually does. San Diego Solar holds both licences, CSLB #970079.
What’s special about roofing in San Marcos?
Roof stock, permitting, and weather exposure differ street to street across San Diego County — and they decide both the right roofing material and the right solar mounting. Here’s how we approach San Marcos specifically.
Read the Roof, Not the Postcode
San Marcos incorporated in January 1963 and was the fastest-growing city in the county through the 1980s, nearly doubling from 17,479 residents in 1980 to just under 34,000 by 1990. That growth left a patchwork: pre-war pockets in Richmar, 1960s and 70s stock around the lake, boom-era tracts, then the 2000s hillside villages. We read the roof, not the postcode.
Climate Zone 10 Rules
San Marcos falls in Climate Zone 10 under Title 24, not the coastal Zone 7 a few miles west. That matters on a re-roof: the cool-roof prescription triggers once work covers more than half the roof, and a steep-slope roof must then hit 0.20 aged solar reflectance with 0.75 thermal emittance. We spec to it as standard.
Mounts Built Into the Roof
On a combined roof-and-solar project our roofers set the attachment points and flashing while the new roof is going down, and the solar crew wires the array onto a finished surface days later. Nothing is cut into a completed roof — the attachment is part of the roof, not a hole through it.
One Licence Covering Both Trades
Architectural review in San Elijo Hills, Rancho Tesoro and Santa Fe Hills goes smoother when roof material and array layout arrive as one submission from one contractor. On the residential solar side, California Civil Code section 714 already voids any condition that adds more than $1,000 to a rooftop system or cuts its output by more than 10%.
How much does a new roof with solar cost in San Marcos?
Budget the package, not two bids. Most San Marcos homes are pitched composition shingle or concrete tile, and it is the flat or low-slope sections where the material below decides the number. Roof area, how many layers come off, and whether the array goes up in the same visit move it most.

Ranges are for a 1,500 sq ft low-slope area. A combined roof-and-solar project runs $30,000–$60,000 before incentives — about 15–20% under hiring a roofing company and a solar company separately. The prepaid lease takes a further 30–40% off the solar portion.
How does a combined roof + solar project work in San Marcos?
One contractor, five stages: a dual roof-and-energy assessment, integrated design with your proposal back inside 48 hours, both permits pulled and sequenced, the roof with solar mounting flashed in, then the array. Crews are on site 3–5 days. Contract to power-on runs 6–10 weeks.
Dual Assessment
We inspect your roof and energy needs in a single visit — roof condition, material options, and the solar layout the new roof should be built for.
Integrated Design
Roof and solar are engineered as one project, so mounting points, flashing, and weatherproofing are built into the roof itself.
Both Permits, One Contractor
A re-roof and a solar install are two separate permits in most San Diego jurisdictions — we hold C-39, C-46 and C-10, so one licensed company pulls both and sequences them under a single contract.
Roof Installation
Our in-house roofing crew installs the new roof with solar-ready mounting points and premium flashing.
Solar Installation
Immediately after the roof is done, our solar crew mounts and wires the array — no waiting weeks for a second company.

San Marcos roofing + solar FAQ
There is no hard number, but the working rule is that a roof needs ten to fifteen years of remaining life to sit under a 25-year array. In practice that rules out most untouched 1960s and 70s coverings around Lake San Marcos and leaves most San Elijo Hills roofs fine. Our free roof-and-energy assessment gives you the verdict either way, including the answer you may not want.
Usually, yes. The California Energy Commission places San Marcos in Climate Zone 10, where the prescriptive residential cool-roof requirement applies once a re-roof covers more than half the roof area. A steep-slope roof needs an aged solar reflectance of at least 0.20 and thermal emittance of 0.75. Coastal Zone 7 cities a short drive west are not held to the same prescription.
Most land between $30,000 and $60,000 before incentives, set by roof size, material and the system size your home needs. Handling both trades under one contract runs 15–20% below two separate companies, and our prepaid lease removes another 30–40% from the solar portion. There is no federal tax credit in that math — it ended on 31 December 2025.
The City of San Marcos Building Division. Because our roofing, electrical and solar classifications sit on one CSLB licence, number 970079, the two scopes go in as a single combined submission rather than two contractors filing past each other. We handle plan check, structural calculations, inspector coordination and the SDG&E interconnection.
It can review the look, not veto the system. We send roof material and array layout as one architectural package so the committee sees a finished design rather than two half-projects. California Civil Code section 714 also voids any condition that would add more than $1,000 to a rooftop solar system or reduce its efficiency by more than 10%.
Most commonly architectural composition shingle or concrete tile, chosen to suit the community's look and the array layout. Whatever the material, the manufacturer warranty typically runs 25 to 50 years, which is what lets us match the roof's service life to the panels above it instead of retiring one long before the other.
You pay to undo it. Taking an array down and resetting it for a re-roof runs about $2,800–$4,800 on a typical residential system, on top of the roofing work and a second round of scheduling. Doing it in the right order once costs less than doing it in the wrong order twice.
Your proposal comes back within 48 hours of the assessment. Crews are on site 3–5 days for a combined roof and array — old roof off, new roof on with mounts flashed in, panels wired straight after. The full arc from signed contract to Permission to Operate is 6–10 weeks, most of it plan check and SDG&E interconnection.
