Roofing in Granada Hills.
Roofing in Granada Hills changes as you climb: flat Valley tracts in the south, fire-zone foothills in the north — and the roof a home needs depends on which side of town it sits on.
What Granada Hills roofs are up against.
Granada Hills stretches from the flat Valley floor up into the foothills of the Santa Susana Mountains, and that range matters. Down in the grid, the story is Valley heat — long hot summers that wear south-facing slopes and dry out tile underlayment. Up in the northern hills, homes sit in elevated fire terrain where a Class A fire-rated assembly and ember-resistant detailing — valley metal, closed eaves, blocking at the ridge — are not optional, especially with the larger lots and open space nearby. Fall Santa Anas rake the ridgelines hard up here, lifting tile and tabs on anything exposed. A Granada Hills roof has to be matched to its spot: heat-built down low, fire-built up high.
What we work on in Granada Hills.
- Concrete and clay tile on the hillside and newer homes
- Asphalt shingle on the Valley-floor ranch tracts
- Flat and low-slope over additions
The repairs Granada Hills homeowners call us about.
- Wind-lifted tile and tabs on exposed foothill ridgelines
- Brittle, slipped tile over failed underlayment
- UV-worn shingles on the Valley-floor homes
- Fire-hardening gaps at eaves, vents, and valleys on hillside homes
What a Granada Hills roof job looks like with us.
On the hillside homes we build Class A assemblies with ember-resistant detailing, because up here that is what protects the house. On the Valley-floor homes we focus on heat-rated underlayment and ventilation. Either way we tear off, inspect the deck, and document the whole job from the air.
We're a family-owned, licensed C-39 contractor (CSLB #1137536), Owens Corning Preferred and Polyglass certified, owner-run by a roofer with nearly a decade of hands-on Los Angeles experience. Our work is backed by a 10-year workmanship warranty and a perfect 5.0 rating across 113 verified reviews.
Common questions from Granada Hills homeowners.
Do you do fire-zone (Class A) roofing in the Granada Hills foothills?
Yes. For homes in the northern hills and near the open space, we install Class A fire-rated assemblies and harden the vulnerable spots — valleys, eaves, and vents — against wind-driven embers. It is some of the most important roofing work we do in this part of the Valley.
The wind keeps lifting tiles on my hillside roof — can you fix it?
Santa Ana winds along the foothill ridgelines are tough on exposed tile and ridge caps. We re-secure and re-detail the ridges and edges so the gusts have nothing to grab, and replace any cracked or slipped tile over fresh underlayment.
How much does a tile roof cost in Granada Hills?
It depends on the roof size, pitch, tile type, and the condition of the underlayment and deck. We come out, scan the roof with a drone, and send a free, written, itemized estimate — no guessing, no pressure.

Roofing codes & requirements in Granada Hills
Energy / cool roof (Title 24)
Granada Hills sits in California Energy Commission Climate Zone 9. Under Title 24, Part 6, a low-slope or flat roof here must use a cool-roof product (aged solar reflectance of at least 0.63 and thermal emittance of at least 0.75 — roughly SRI 75) when you replace 50% or more of the roof or about 1,000 sq ft or more. Steep-slope (pitched) residential roofs in Climate Zone 9 are exempt from the cool-roof requirement, so standard shingle or tile is fine. Small like-for-like repairs generally don't trigger it. See the California Energy Commission standards and the CRRC directory for rated products.
Fire — hillside parcels
Granada Hills' northern foothill parcels near the Santa Susana Mountains and Aliso Canyon are in a Very High Fire Hazard Severity Zone, where Chapter 7A requires a Class A roof assembly and ember-resistant construction; flatter southern parcels generally aren't. You can check any parcel on the CAL FIRE hazard-zone viewer.
Decking / sheathing
Many older Granada Hills homes were built with spaced 1×6 “skip” sheathing under the original roof. For a modern shingle or tile system — and for a Class A assembly — that decking often has to be overlaid with solid sheathing, and any rotted boards replaced. We confirm exactly what your roof needs with a deck inspection at tear-off, not a guess.
Color & materials
Roof color isn't regulated by code. Where a cool roof is required you need a CRRC-rated product that meets the SRI — and those come in a wide range of colors, not just white.

Common Granada Hills roofing-code questions
Does my Granada Hills roof need to be Title 24 cool-roof compliant?
Only on flat or low-slope sections. Granada Hills is in Climate Zone 9, so Title 24 requires a cool roof (about SRI 75) when you replace 50%+ of a low-slope roof, but steep-slope shingle and tile roofs are exempt here.
Is Granada Hills in a fire zone that requires a Class A roof?
It depends on your parcel. Granada Hills's hillside/foothill properties are in a Very High Fire Hazard Severity Zone and need a Class A assembly with ember-resistant details; flatter parcels usually don't. We check the CAL FIRE map for you.
Will my old spaced sheathing need to be re-decked?
Sometimes. Older Granada Hills homes often have spaced 1×6 sheathing; a modern shingle or tile system (and a Class A assembly) may need solid sheathing over it. A deck inspection at tear-off tells us for sure.
Financing available for qualified Granada Hills homeowners
You don't have to pay for a roof all at once: financing is available for qualified homeowners, subject to qualification — written itemized pricing first, financing second, never any pressure. And because Title 24 cool-roof products are qualifying energy improvements, a Granada Hills re-roof that needs one may also qualify for PACE-style energy financing — ask us and we'll confirm what applies to your property.
