Roofing in Santa Maria, CA: Choosing Materials for Fog, Wind, and Older Roofs
Santa Maria has no High or Very High fire hazard zone, and it sits in California building Climate Zone 5, so neither a fire-zone rule nor the cool roof rule picks the material for a home reroof here. Roofing in Santa Maria, CA, comes down to the valley’s fog and wind, the age of the roof you have, and what you want from the next one.

Half of Santa Maria's homes date from 1980 or later
Santa Maria is the most populous city in the county. It grew from 61,284 residents in 1990 to 99,553 in 2010 and 109,707 in 2020. In census survey data (ACS 2020-2024), 53.3% of the city’s 30,482 housing units were built in 1980 or later, the median year built is 1982, and 60.3% are single-family detached houses.

For reroofing, that splits the city in two. The roughly 13,100 units from the 1980s through the 2000s are now reaching their first or second replacement, usually a standard tear-off with decking repairs, new underlayment and flashing, and the new roof. Older houses, including 2,089 units built before 1950, may have been reroofed more than once, so we look for stacked layers, patched decking, and reused flashing.
Roofing in Santa Maria, CA: picking a material for fog and wind
Two rules that set roof materials elsewhere in California do not apply to most Santa Maria homes. CAL FIRE’s 2025 figures list 0 acres of Very High or High fire hazard in the city and 1,301.2 acres of Moderate, the lowest level. In Climate Zone 5, California’s energy code also requires no cool roof on a home reroof, steep-slope or low-slope. Ask the City’s Building Division whether any citywide minimum roof class applies; we confirm it before you choose.
That leaves the climate. Wikipedia calls the Santa Maria Valley “often foggy and windswept.” With an average daily high of 69.6°F, heat rarely decides the color, though the airport station hit 110°F on June 20, 2008. Rain averages 13.32 inches a year but has ranged from 4.25 to 32.56 inches, so a worn roof can get through a dry winter and leak in a wet one. Here is how the usual options fit:
- Architectural shingles: usually the lowest-cost option and the simplest to repair after a windstorm. Ask for a high-wind-rated product and a sealed starter course.
- Concrete tile: heavy, so a switch from shingles starts with a check of the framing. The underlayment beneath the tile keeps the water out, so a tile roof replacement here needs as much care below the tile as on top.
- Standing seam metal: long panels with concealed fasteners. A metal roof replacement is only as good as its flashing at walls, valleys, and vents.
- Cap sheet or TPO: for low-slope porch roofs and additions, in any color on a house.
With any of them, balanced attic ventilation keeps damp air from collecting under the roof deck.
Santa Maria roof repair, house reroofs, and warehouse roofs
The work we take on in Santa Maria falls into three groups:
- Roof repair: wind-lifted shingles, cracked or slipped tile, worn flashing at chimneys and walls, and leaks that show up in a wet winter.
- House reroofs: tear-off, decking repairs, new underlayment, and the shingle, tile, or metal roof you choose, under a City building permit.
- Commercial low-slope roofs: TPO, modified bitumen, and reflective coatings on warehouses, packing buildings, and stores.
Commercial low-slope roofs work differently. In every California climate zone, a nonresidential low-slope roof needs a rated cool roof when it is replaced, with some exceptions. Agriculture (strawberries, wine grapes, celery, lettuce, broccoli, and more) is still a key part of the local economy, so the rule reaches packing and storage buildings as well as warehouses and shops. A white TPO membrane or a rated reflective cap sheet usually meets it.

What Santa Maria homeowners ask before choosing a new roof
Where do I apply for a reroof permit in Santa Maria?
At the City of Santa Maria Building Division, part of the Community Development Department, at 110 S. Pine St., Room 101. The counter is open 8 a.m. to 4 p.m., and phones are answered from 7:30 a.m. to 5 p.m. at (805) 925-0951, ext. 2241. The City also takes applications online.
Is any part of Santa Maria in a High or Very High fire hazard zone?
No. CAL FIRE’s figures show 0 acres of High and 0 acres of Very High fire hazard in the city, and none of Santa Maria was Very High on the earlier maps either. About 1,301 acres are Moderate, and downtown is NonWildland. The Santa Maria Fire Department published its updated map after CAL FIRE’s March 10, 2025 release.
Does a Santa Maria home need a cool roof or a light-colored roof?
No. Santa Maria is in building Climate Zone 5, where California’s energy code sets no cool roof requirement for home reroofs, steep-slope or low-slope, or for low-slope roofs on apartment buildings. On a house, the color of the shingle, tile, or metal is your choice. Nonresidential low-slope roofs are different and need a rated cool roof.
My Santa Maria house was built in the 1980s. Should I repair the roof or replace it?
Start with the age of the roof itself. If the house still has its original 1980s roof, plan on replacement, or on new underlayment if the roof is tile. If it was reroofed in the 2000s, repairs may be enough. Yearly rainfall here has swung from 4.25 to 32.56 inches, so have a worn roof checked before a wet winter.
