Why Tilehurst Roofing Is Walnut’s Preferred Roof Repair Company
Tilehurst Roofing is a Kingswell family company, founded in 2000, and the Walnut location is independently owned and operated under the Kingswell Guarantee. Led by Greg Holloway, our team has repaired hundreds of concrete tile roofs across Walnut’s hillside subdivisions. Homeowners here tend to call us after a previous contractor patched a leak from above and the stain came back in three months. They want someone who opens the problem up and finds the actual source.
Every repair leaves your house with a written guarantee, not a verbal promise. If the repair fails inside the guarantee period, we return at no charge under our 365-Day Done Right Promise. A live person answers every call, 24 hours a day, 7 days a week. That includes Sunday evening, when a Santa Ana gust just ripped a hip tile off your south-facing slope.
Roof Leak Repair in Walnut
Roof leak repair in Walnut often means finding damage that starts beneath tiles that look perfectly fine from the street. Our Roof Repair team responds to Walnut calls with background-checked, uniformed technicians who arrive in the window we gave you. The process starts with a careful inspection of the roof field, flashing points, and valleys, because on Walnut’s multi-plane tile roofs, the leak you see on the ceiling is rarely directly above the failed material.
What we check first
Valley flashings, pipe boot collars, and ridge mortar are the usual suspects. But on Walnut homes built in the 1980s and 1990s, we also check the underlayment beneath the tile. If the Type 15 felt underneath has gone brittle, the leak will keep returning no matter how many times someone caulks the surface.
Why patch jobs fail here
A spot repair from above can’t fix degraded felt under intact tile. We open the affected field, replace the failed underlayment and any rusted flashing, reset the original tile, and leave the roof matching the surrounding area. Expect Walnut concrete tile leak repairs to run $650 to $1,800 depending on how far the water traveled.
Emergency Roof Repair in Walnut
Emergency roof repair in Walnut is most often a wind-driven event, and it needs to be handled safely. Santa Ana winds funnel through the San Gabriel Valley against the Puente Hills and routinely dislodge ridge caps and hip tiles on exposed slopes near Snow Creek, Three Oaks, and the higher streets above Valley Boulevard. When that happens, water has a direct path into the underlayment and decking below.
Quick sealing to stop the damage
We can install a temporary weatherproof seal over the exposed area and return to complete the permanent repair. The goal is simple: stop the water from doing worse damage overnight. Emergency temp sealing in Walnut typically runs $300 to $550, with the permanent repair quoted in writing before any work begins.
Permanent fixes after a storm
After the area is dry, we re-bed ridge caps with fresh mortar, reset hip tiles with proper fasteners, and replace any underlayment the exposure damaged. If your parcel falls within the Very High Fire Hazard Severity Zone near the Puente Hills, we’ll match the assembly to the Class A requirement your property carries. Every emergency repair gets a written guarantee before the crew leaves.
Trusted Brands We Service in Walnut
Walnut roofs carry concrete tile, asphalt shingle, and occasional flat roof sections, and we service them all. We install and repair GAF, CertainTeed, and Owens Corning products, among others, and we source materials locally so a Walnut repair isn’t waiting on a shipment from out of state. If your roof needs matching tile, we work with local salvage and supply yards to find pieces that blend with your existing field. The product fits the home, not just what happens to be on the truck.
Common Roof Repair Problems We See in Walnut Homes
- Silent underlayment failure: Walnut’s 1980s-1990s tile roofs sit on original Type 15 felt that’s now 30-40 years old. The tiles look great from the curb, but the felt beneath has turned brittle and leaks surface inside long after the damage happened.
- Santa Ana ridge cap damage: The inland San Gabriel Valley is a known funnel point for wind. Homes on elevated terrain near the Puente Hills lose ridge caps and hip tiles when the mortar bed ages out, and each missing piece opens a path for rain.
- Valley flashing corrosion: Complex hip-and-valley rooflines concentrate water flow. When valley metal corrodes or the sealant fails, the leak travels along rafters and shows up far from the actual opening.
- Class A code surprises: Portions of Walnut near the Puente Hills fall within LA County’s Very High Fire Hazard Severity Zone. A like-for-like tile swap won’t pass permit inspection if the underlayment assembly doesn’t meet Class A standards.

FAQs About Roof Repair in Walnut
The underlayment beneath your tile has likely failed. Walnut homes built in the 1980s and 1990s were typically roofed with Type 15 felt, which turns brittle after 30-40 years of inland sun and wide temperature swings. The tiles above still do their job, but water gets through the cracks, hits the degraded felt, and travels to the ceiling. The fix is opening the affected field, replacing the underlayment, and resetting the tile. Call (945) 303-9821 for an inspection and a written quote.
It depends on your parcel. Portions of Walnut near the Puente Hills fall within LA County’s Very High Fire Hazard Severity Zone. If your home is in that zone and the reroof or repair area exceeds a certain size, the permit will require a Class A-rated assembly, which means specific underlayment and tile combinations. A budget felt product won’t pass. We check your address against the fire zone map before quoting so you aren’t surprised at inspection. Call (945) 303-9821 and we’ll confirm your status.
Small targeted repairs like a pipe boot replacement or a few tiles usually don’t trigger a permit. But if we’re opening a larger field, replacing underlayment, or your home is in the fire hazard zone, the city may require one. Opening an older Walnut roof often turns up the same things: degraded felt, corroded valley metal, and flashing that wasn’t installed correctly the first time. We inspect first, then write any required upgrades into the contract as a specific allowance before work starts, and we never change the price mid-job without your written approval. That’s the Kingswell Way.
Look at the underlayment line item first. If one bid prices a full underlayment replacement in the damaged field and the other only mentions sealing or patching from above, the cheaper bid will likely fail within a year. On a Walnut tile roof, that’s the single biggest difference between a repair that lasts and one that doesn’t. Compare line items side by side, and make sure every bid includes a written guarantee. Ours does, on every repair, before the crew leaves. Call (945) 303-9821 to schedule a free estimate.
The mortar bed that held it aged out. Walnut’s inland climate bakes mortar through 100°F-plus summers, and Santa Ana gusts finish the job. A loose hip tile usually means the ridge line needs re-bedding, not just one tile re-set. On a job near Snow Creek, we went up for what the homeowner called a simple repair and found the ridge mortar crumbled and the felt underneath shredding under intact tile. We opened the field, replaced the underlayment and flashing, added new ice and water shield at the valleys, re-bedded the ridge caps, and reset the original tiles. The homeowner kept their tile, and the assembly matched the Class A requirement their parcel falls under. If your hip tile came loose, call (945) 303-9821 for a free estimate. We’ll tell you what actually happened up there.
