San Gabriel Valley Roofing.
The San Gabriel Valley is where Los Angeles keeps its history — the 1920s Craftsman bungalows of South Pasadena (91030), the period-revival estates of San Marino, and the rebuilt tile homes of Arcadia, all under the San Gabriel Mountains. Samuel Roofing Inc. is a family-owned, owner-operated contractor that respects what these roofs are: many are original, many are tile, and most need a careful hand rather than a hard sell. Roofing done right — and proven from the air.
Climate & conditions
The SGV runs hot and dry through the summer, with strong UV on south-facing slopes, and it catches the dry-season Santa Ana winds funneling down out of the foothills. Communities along the northern edge — the upper reaches of Arcadia, Sierra Madre, and Monrovia toward the mountains — carry real wildfire exposure, while the older flatland neighborhoods deal with the slow problems: aging clay and concrete tile, underlayment that has outlived its service life, mature tree canopy dropping debris into valleys, and the moss and trapped moisture that come with all that shade.

San Gabriel Valley roofing questions
Can you renew the tile on my older San Marino or South Pasadena home? Often, yes. If the clay or concrete tile is still sound, we lift and reset it over fresh underlayment — restoring the roof's life while keeping its original look. We'll tell you honestly during the free inspection whether renewal or full replacement is the right call.
Do you handle historic-home roofing standards? Yes. On Craftsman and period-revival homes we match profiles and detailing so the roof reads correctly and meets neighborhood expectations.
Are the foothill areas of Arcadia a fire concern? The northern edge toward the mountains carries wildfire exposure, so we build those roofs with Class-A fire-rated assemblies.

Roofing codes & requirements across the San Gabriel Valley
Energy / cool roof (Title 24)
The San Gabriel Valley is largely in Climate Zone 9 (confirm your ZIP, as some inland areas reach Zone 10). Under Title 24, flat or low-slope roofs need a cool roof (about SRI 75) on a re-roof of 50%+ or 1,000+ sq ft; steep-slope roofs are exempt in Zone 9 but required in Zone 10. See the California Energy Commission standards.
Fire (Chapter 7A)
The flat valley floor generally isn't in a Very High Fire Hazard Severity Zone, but the northern foothill cities along the Angeles National Forest — Pasadena, Arcadia, Glendora, La Cañada Flintridge, Sierra Madre, Monrovia — have VHFHSZ parcels requiring a Class A roof and ember-resistant construction. You can check any parcel on the CAL FIRE hazard-zone viewer.
Decking / sheathing
Many older homes here have spaced 1×6 sheathing; for a modern shingle or tile system — and a Class A assembly — that often needs solid sheathing over it. A deck inspection at tear-off tells us for sure.
Permits & jurisdiction
Each San Gabriel Valley city issues its own permits; unincorporated areas go through LA County Public Works.
Source: the California Energy Commission, CAL FIRE, and your San Gabriel Valley city's building department. Roofing codes change and are parcel- and city-specific — confirm with your local building department before your project, or call us at (866) 685-3889 and we'll confirm it for you.
Common the San Gabriel Valley roofing-code questions
Do roofs in San Gabriel Valley need to be Title 24 cool-roof compliant?
On flat or low-slope sections, yes, when you replace 50% or more of the roof. Steep-slope shingle and tile roofs are generally exempt in this area's climate zones (Zone 6/8/9). We confirm the rule for your address.
Is San Gabriel Valley in a fire zone that requires a Class A roof?
It depends on the parcel. Hillside, foothill, and canyon areas are often in a Very High Fire Hazard Severity Zone that requires a Class A assembly and ember-resistant construction; flat areas usually aren't. We check the CAL FIRE map for your address.
Who issues my roofing permit in San Gabriel Valley?
It depends on your city — each city runs its own building department, and unincorporated areas go through the county. We pull the permit through the right jurisdiction for your project.
Financing available for qualified San Gabriel Valley 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 San Gabriel Valley re-roof that needs one may also qualify for PACE-style energy financing — ask us and we'll confirm what applies to your property.
