Roofers in Walnut, CA
Roof work in Walnut starts with knowing what’s actually above your ceiling. Most homes here were built between the 1960s and 1990s, and a lot of them still carry the original concrete or clay tile from that era. The tile looks fine. The underlayment beneath it usually isn’t. That’s why we begin every Walnut job with a Roof Inspection, not a sales pitch. Weston Roof Repair has served Walnut since 2015. Call (833) 589-6925 when you’re ready for a straight answer about your roof.
Why Walnut Homes Are Different
Walnut sits at the edge of the San Gabriel Valley where the hills meet the Santa Ana wind corridor. That location creates a specific set of roof problems. The hot, dry inland summers bake tile underlayment until it turns brittle, long before the tile itself shows any wear. When the Santa Anas kick up in fall, they drive embers into roof crevices and lift loose edges. In the 91788, 91789, and 91795 ZIP codes, we regularly open up roofs where the concrete tile is still structurally sound but the felt underneath has disintegrated after 30 years of UV exposure and heat cycling. Walnut’s hillside tracts have their own complications: steeper pitches, limited staging areas, and HOAs that enforce strict appearance standards. Replacing underlayment on a Spanish-style tile roof here isn’t just a tear-off. It requires a lift-and-relay process, city permits, and an HOA-approved material match. The rare winter storm years test the remaining life in that underlayment, and by the time a leak shows on the ceiling, the problem has usually been developing for years.
Styles & brands we work with
Our Main Walnut Services
Most Walnut homeowners call us about one of two things: a repair to fix an active problem, or a full replacement to get ahead of one. Here’s how each works in this city.
Roof Repair in Walnut
Repairs here are rarely as simple as swapping a shingle. With tile roofs dominating so much of Walnut, the call that comes in as “a small leak near the chimney” often turns into a section-wide underlayment replacement once we lift the tiles and see what’s underneath. Wind from the San Gabriels loosens tiles, and baked underlayment lets moisture through even when the tile above looks intact. We diagnose first, then fix what’s actually wrong. Roof Repair in Walnut includes everything from tile re-securing and flashing replacement to full underlayment lift-and-relay work.
Roof Replacement in Walnut
When a Walnut roof reaches the end of its useful life, replacement means matching the existing aesthetic. Concrete tile, clay tile, and architectural shingle each handle the Santa Ana wind corridor differently. HOA and city approval usually depends on keeping the look consistent with the neighborhood. We work through the permit process and install across all major brands so the replacement fits both the home and the community standards. Roof Replacement in Walnut is handled by the same crew that inspects and repairs, start to finish.

Roof Inspection in Walnut
Under Walnut’s tile roofs, the tile often outlives the underlayment. We routinely find 30-year-old felt baked brittle under tiles that still look fine from the street. That means a leak usually signals a full underlayment lift-and-relay, not a simple patch, and the work must pass city and HOA appearance review. A Roof Inspection in Walnut is a diagnostic step that tells you exactly what you’re working with before anyone asks you to spend money. It’s the service we recommend first here, because guessing on a tile roof is expensive.
Roof Inspection Services
Signs you need it
Water stains on ceilings, granule buildup in gutters, or visible tile cracks usually mean the underlayment has already started failing.

Roof inspection pricing starts around $95 for a limited tile check in Walnut, with more extensive tile-to-deck underlayment inspections running $650 to $900.
How we do it
We walk the roof, lift selected tiles, check the underlayment’s remaining life, and document every finding with photos you keep.
Hail Damage Roof
Signs you need it
After a rare hail event in the San Gabriel Valley, look for cracked or chipped tiles and dented flashing that can’t shed water properly.

A small hail-related repair in Walnut runs $250 to $900, while more extensive underlayment replacement after hail ranges from $260 to $835 on average.
How we do it
We check tile condition, test underlayment, and give you a written repair scope that addresses actual damage, not what a storm chaser wants to sell.
Roof Estimate
Signs you need it
When your roof is past 20 years old or you’re planning a sale, a formal estimate gives you numbers instead of guesswork.
What it costs in Walnut
Basic roof estimate pricing in Walnut starts around $95 for a limited tile inspection with pricing, and runs $650 to $900 for a thorough tile-to-deck inspection and quote.
How we do it
We inspect first, then price the repair or replacement with line-item clarity so you know exactly what you’re paying for.
What Roof Inspection Costs in Walnut
| Item | Typical range in Walnut |
|---|---|
| Basic roof inspection (limited tile check) | $95 – $120 |
| Tile-to-deck underlayment inspection (same-day detailed inspection) | $650 – $900 |
| Hail damage inspection | $250 – $900 (inspection plus minor repair scope) |
How often should a Walnut tile roof be inspected?
Every 3 to 5 years at minimum. Underlayment has a 20 to 30 year life, and Walnut’s heat cycles shorten it. Catching it before it fails saves a full deck replacement later.
Can a roof inspection tell me if I need a repair or a full replacement in Walnut?
Yes, that’s the entire point of the inspection. We open up sections of tile and check what’s underneath. Then we tell you honestly which option makes sense. Call (833) 589-6925 to schedule yours.
Brands We Service in Walnut
We work with IKO, Atlas, and Tamko, plus the other major shingle and tile manufacturers, which means our recommendation is based on what your Walnut roof needs, not what we happen to stock. We keep common replacement parts available locally for faster turnaround on repairs throughout the San Gabriel Valley. Our brands page covers the full lineup.

FAQs About Roofers in Walnut
Yes. Walnut requires building permits for full roof replacements, and most hillside HOAs require architectural review before any material changes. Tile-to-tile swaps still need city approval. We handle the permit application and HOA paperwork as part of the job. Call (833) 589-6925 if you want us to check requirements for your specific address.
We typically book Walnut inspections within 3 to 5 business days, depending on the season. Fall, during Santa Ana wind season, fills up fastest. If you have an active leak, call (833) 589-6925 directly and we’ll tell you the soonest available slot on the phone.
Yes. Most Walnut homes have concrete or clay tile, so underlayment replacement and tile lift-and-relay work dominate our schedule here.

What Walnut Customers Say
"Quality work on the repair. There were a few nails left in the driveway that the magnet missed, so check yours before driving over it. Otherwise no complaints."
— Kurt Doyle"Full replacement after the hail. They handled the insurance adjuster meeting, documented everything, and I did not have to argue with anybody. Crew was here three days and the yard was cleaner when they left than when they started."
— Claudia Hernandez"Roof is solid and the price was competitive. The job ran a day over because of weather, which is nobody's fault, but I would have liked a call about it rather than noticing the crew hadn't shown up."
— Wade Delaney
