Houses from the 1960s through the 1980s: patch the roof or replace it
Grand Terrace built most of its housing in three decades: 19.4% in the 1960s, 23.4% in the 1970s, and 24.3% in the 1980s (American Community Survey, 2014 to 2018). Only 7.9% dates from 2000 or later, and the median home was built in 1978. The City’s draft 2021-2029 Housing Element estimates that about 20% of homes need minor repairs and about 5% may need more substantial rehabilitation.
A roof on a house that age may be its second or third, and the surface doesn’t show the deck underneath. We start with a roof inspection that looks at the decking from the attic as well as the covering from above, then sort the findings:
A leak at flashing, a vent, or one valley
Targeted repair
A few broken shingles or tiles on a sound roof
Replace those pieces and reseal
Soft or stained decking in several areas
Tear-off, with new decking where needed
Worn covering across most of the roof
Full reroof under the cool roof rule
The cool roof rule applies when more than 50% of the roof is replaced (2025 California Energy Code).
That 50% line also has a code consequence. Grand Terrace is in climate zone 10, so under the 2025 California Energy Code, in effect since January 1, 2026, replacing more than half of a residential roof calls for a product rated by the Cool Roof Rating Council (CRRC) on steep slopes and cool roof compliance on low slopes. A smaller repair doesn’t trigger the rule.
Blue Mountain lots: Class A roofing and County Fire's 2025 map
Blue Mountain rises along the east side of Grand Terrace. The Housing Element places Hillside Residential (RH) and R1-20 lots on its steep slopes and R1-10 lots along its foot, and it says the hillside sites carry high fire hazards as well as landslide and flooding risks.
The fire maps changed in 2025. The previous State map for local areas, last updated between 2008 and 2011, showed only Very High zones; CAL FIRE’s new map, dated March 24, 2025, adds Moderate and High. The City’s fire page sends residents to San Bernardino County Fire, its contract fire service, and the Board of Supervisors adopted the map as County Fire Protection District Ordinance No. 4489 on June 10, 2025.
In CAL FIRE’s map data, a point on the east-side hill is Very High, while a point in central Grand Terrace is non-wildland. Two points don’t settle a whole hillside, so we check your parcel on the 2025 map before quoting and specify a Class A roof where it is Very High.
Slope affects water as well as fire. With landslide and flooding risks on the same lots, we also check how water leaves a Blue Mountain roof: valleys, drip edge, and where gutters and downspouts empty. The San Bernardino County roofing guide covers the 2025 maps countywide.
What hiring a roofing contractor in Grand Terrace, CA, involves
We handle roof repair and replacement projects in Grand Terrace and schedule each inspection visit in advance. The City lists re-roofing among the projects that require a building permit, and we prepare the application for Building & Safety. Inspections are requested by email with the permit number, requested date, inspection type, and any gate code, and animals must be kept away from the inspection area, so we confirm gate and pet arrangements with you first.

Grand Terrace roof questions: permits, Blue Mountain, and mobile homes
Who issues the permit for a reroof in Grand Terrace?
The City of Grand Terrace, through Building & Safety at 22795 Barton Road. The counter is open weekdays from 8 a.m. to 5 p.m., with permit hours from 1:00 to 4:30 p.m., and it accepts PDF and electronic submittals. A permit is typically valid for six months from issuance or from the last approved inspection, and homeowners may pull their own after completing an Owner-Builder form.
Is my Blue Mountain home in a Very High fire hazard zone?
Check the parcel itself. On CAL FIRE’s 2025 map data, the east-side hill point is Very High and a central point is non-wildland, so the answer can change over a short distance. The City’s fire page points to San Bernardino County Fire for the map, and a replacement roof in a Very High zone must be Class A rated.
Does Grand Terrace publish its own reroof handout?
Not among its standard details, which cover patio covers, decks, walls, and pools. A reroof follows the 2025 California codes the City has adopted, including the Building, Residential, Energy, and Fire codes. Questions about a specific roof go to Building & Safety at (909) 954-5181, and we check the requirements there before work starts.
Can you repair the roof on a mobile home in Grand Terrace?
Yes, once we confirm how the roof is framed and which agency permits the work. Grand Terrace has 292 mobile homes, 6.2% of its housing, and its Housing Element notes that many elderly owner households live in them. We photograph what we find and put the scope in writing, so an owner can review it without going up a ladder.
