Walnut roofing,

Our work in Walnut

What Walnut roofs are up against.

Walnut is a newer, hillier community in the east San Gabriel Valley, and its roofs reflect that — largely tile-roofed homes built from the 1970s on, set on the rolling hills and ridgelines that give the area its character. Up on the slopes, homes catch the wind, and Santa Ana gusts lift exposed tile and loosen ridge caps. The inland summers are hot, baking south-facing slopes and drying tile underlayment, and the larger newer homes carry complex rooflines — lots of valleys, hips, and penetrations where the workmanship details decide whether the roof leaks. Even on newer homes, the underlayment beneath the tile reaches the end of its life on the original-roof timeline. Walnut roofing is about wind, sun, and getting the details of a complex tile roof right.

The roofs we work on most in Walnut: Concrete and clay tile on the hillside homes; Composition shingle on some homes; Flat and low-slope over additions and modern wings.

Most of what we're called for here: Wind-lifted tile and ridge caps on the ridgelines; Failed underlayment on original-era tile roofs; Flashing failures at the many valleys of larger homes.

Every stage of our work is photographed by drone so you can see the deck before it's covered. That documentation isn't an extra — it's how we work on every roof.

Walnut rules that affect your roof

Title 24, fire zones, and old decking — what applies to your house.

We check what applies to your parcel before we quote, and we'll confirm it with the permitting authority for you.

Energy / cool roof (Title 24)

Walnut 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

Walnut's hillside parcels are in a Very High Fire Hazard Severity Zone, where Chapter 7A requires a Class A roof assembly, ember-resistant vents, and non-combustible flashing (no wood shake). Flatter parcels generally aren't. You can check any parcel on the CAL FIRE hazard-zone viewer.

Decking / sheathing

Many older Walnut 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.

Financing

Financing available for qualified Walnut 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 Walnut re-roof that needs one may also qualify for PACE-style energy financing — ask us and we'll confirm what applies to your property.
