Roofing in Arcadia.
Roofing in Arcadia spans two worlds: older tree-shaded homes near the Arboretum and Santa Anita, and a wave of larger newer builds — both with tile roofs that have to take real San Gabriel Valley heat.
What Arcadia roofs are up against.
Arcadia sits at the foot of the San Gabriel Mountains, and its summers are hot and dry. That heat and UV bakes south-facing slopes and dries out tile underlayment, while the mature trees that shade so many Arcadia streets — and the Arboretum nearby — drop steady debris into valleys and gutters. The city blends older tree-canopied neighborhoods with a large number of newer, bigger homes, and tile dominates both. On the older homes the underlayment under decades-old tile is the usual culprit; on the newer ones it is the workmanship details at the many valleys, hips, and penetrations a larger roof carries. Santa Ana winds off the foothills add wind exposure on the ridgelines. A roof here has to handle heat, debris, and a lot of tile.
What we work on in Arcadia.
- Concrete and clay tile on both older and newer homes
- Composition shingle on some mid-century homes
- Flat and low-slope over additions
The repairs Arcadia homeowners call us about.
- Failed underlayment beneath aging tile
- Debris-packed valleys and gutters under heavy tree canopy
- Flashing and detailing failures on the many valleys of larger homes
- UV-worn slopes and wind-lifted ridge tile
What a Arcadia roof job looks like with us.
On an Arcadia tile roof we replace the part that actually fails — the underlayment — usually with a lift-and-relay that saves your tile, and we rebuild the flashing at every valley and penetration. On the larger newer homes, getting those details right is most of the job. Drone-documented throughout.
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 Arcadia homeowners.
Do you work on large tile roofs in Arcadia?
Yes — many Arcadia homes are big tile roofs with lots of valleys, hips, and penetrations, and that is where the detailing has to be right. We rebuild the flashing and underlayment properly so a complex roof actually stays dry.
My tile looks good but the roof leaks — what is wrong?
The underlayment beneath the tile has failed. Tile lasts for decades; the felt under it does not. We lift and save the tile, replace the underlayment and flashing, and re-lay it so the roof is watertight and the look is unchanged.
How much does a tile roof cost in Arcadia?
It depends on size, pitch, tile type, and the condition underneath. We scan the roof with a drone and send a free, itemized written estimate rather than quoting blind.

Roofing codes & requirements in Arcadia
Energy / cool roof (Title 24)
Arcadia 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 — foothill parcels
Arcadia's northern foothill neighborhoods near the Angeles National Forest are in a Very High Fire Hazard Severity Zone — over 1,000 parcels on CAL FIRE's 2025 map — where Chapter 7A requires a Class A roof assembly and ember-resistant construction; the flatter southern city isn't. You can check any parcel on the CAL FIRE hazard-zone viewer.
Decking / sheathing
Many older Arcadia 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. On a Pasadena landmark or historic-district property, the design review may also weigh in on material and color.

Common Arcadia roofing-code questions
Does my Arcadia roof need to be Title 24 cool-roof compliant?
Only on flat or low-slope sections. Arcadia 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 Arcadia in a fire zone that requires a Class A roof?
It depends on your parcel. Arcadia'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 Arcadia 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 Arcadia 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 Arcadia re-roof that needs one may also qualify for PACE-style energy financing — ask us and we'll confirm what applies to your property.
