Roofers in Walnut, CA
Most roofing work in Walnut is not a full tear-off. It’s tile repair, underlayment replacement, and re-sealing work on large two-story Mediterranean homes built in the 1980s and 1990s. Those original felt underlayments are now past their 20 to 25 year lifespan, even when the barrel tiles above them still look fine from the street. We inspect first, recommend second, and handle repair or replacement without handing you off to another contractor. Call (833) 467-4901 to schedule a free roof inspection in Walnut.
Why Walnut Homes Are Different
Walnut sits in the eastern San Gabriel Valley, where summers run hot and dry and Santa Ana winds push down through the canyons each fall. Those winds crack concrete tile and lift edges that have been baking in 100-degree UV for two decades. The bigger issue is what is underneath. Builders in the 1980s and 1990s put clay and concrete barrel tile over felt underlayment, and that felt does not last as long as the tile. A roof can look untouched from the curb while the waterproof layer beneath it has turned brittle and begun to fail.
The hillside tracts in 91789 and parts of 91788 face additional scrutiny. Wildfire ember exposure along the northern edges means the county enforces stricter fire-resistant assembly requirements for re-roofing. When we work in Walnut, we are typically pulling tile, inspecting the deck and flashing, and then re-setting the same tile over new underlayment that meets current Class A fire-rated assembly standards. The work is invisible from the street, but it is the difference between a roof that sheds water and one that leaks through the first winter storm.
Styles & brands we work with
Our Main Walnut Services
Two calls dominate in Walnut: a homeowner who found water staining a ceiling after a rare rainstorm, and a homeowner whose real estate agent flagged the roof during a pre-sale inspection. Both start the same way, with an honest condition report.
Roof Repair in Walnut
Walnut roof repair is rarely a single broken tile. It is usually failed flashing around a valley or chimney, cracked tiles from Santa Ana wind damage, or a section of underlayment that has given out under tiles that look fine. We lift and re-set existing tile wherever possible, which keeps the repair visually consistent with the rest of the roof. You get a written diagnosis, a fixed price, and one crew that handles the whole fix. See Roof Repair in Walnut for the full scope, including what a leaking roof typically costs to fix in this market.
Roof Replacement in Walnut
When the underlayment has failed across multiple slopes, patching stops making sense. Walnut roof replacement means a full tear-off of the old tile and felt, deck inspection and repair where needed, new fire-rated underlayment, and then a decision: re-set the original tile or move to a new material. Because we carry seven brands including GAF and Boral, the material choice follows your roof and budget, not our inventory. Learn more about what a full replacement costs and the timeline on our Roof Replacement in Walnut page.

Roof Inspection in Walnut
Roof Inspection in Walnut exists for one reason: most tile roofs hide their problems. The original 1990s underlayment on a two-story Mediterranean home in 91789 can be completely shot while the barrel tiles sit there looking perfect. A standalone inspection gives you the truth about what is underneath before you spend anything on repair or replacement. We offer Roof Inspection without any obligation to buy a repair, because an honest condition report is the only legitimate starting point.
Roof Inspection Services
Signs you need it
You should schedule an inspection if your Walnut home was built before 2005, has the original roof, or showed water staining on any ceiling after a winter rain.
What it costs in Walnut
Roof inspections in Walnut typically run between $150 and $350, and many contractors including us waive that fee if you move forward with a repair or replacement.
How we do it
We walk the whole roof, lift tile in representative sections to check the underlayment, inspect flashing at valleys and penetrations, and photograph everything so you can see the actual condition.
Free Roof Inspection
Signs you need it
A free inspection makes sense before listing a Walnut home, after a wind event, or when an insurance claim requires a documented roof condition report.
What it costs in Walnut
Free roof inspections in Walnut are typically offered as part of a repair or replacement estimate; a condition-only report without any work typically costs between $150 and $350.
How we do it
We assess the roof, document what we find with photos and measurements, and give you a written report with options ranked by urgency and cost.
What Roof Inspection Costs in Walnut
| Item | Typical range in Walnut |
|---|---|
| Standard roof inspection (condition report) | $150 – $350 |
| Inspection credited toward repair/replacement | $0 with contracted work |
| Drone or infrared inspection add-on | $200 – $400 |
Can you inspect a tile roof without breaking the tiles?
Yes. We lift tiles carefully with flat bars and re-set them in their original position. A proper inspection of a tile roof in Walnut requires lifting tile to see the underlayment, and it should never leave visible damage or loose tiles behind.
Will the inspection tell me if I need repair or replacement?
Yes. The report separates what is urgent from what can wait. If the underlayment is failed on one slope, repair makes sense. If it is failed across the roof, replacement is the honest recommendation. Call (833) 467-4901 to schedule one.
Brands We Service in Walnut
We install and service roofs from seven manufacturers, including GAF, Boral, Atlas, and Tamko. That breadth matters in Walnut, where tile profiles, color matching, and fire-rated assembly requirements vary by neighborhood. We stock common replacement tile and flashing parts locally, and we can usually source brand-specific materials within a few days when an exact match is needed. See our brands for the full list.

Prices in Walnut push higher than the valley average for two reasons: two-story homes on hillside lots need more safety setup and slower work, and tile re-setting is labor-intensive compared to shingle tear-off. You get a fixed written price before we start, and that number does not change unless we uncover deck damage that was impossible to see before removal, and we document it before proceeding.

FAQs About Roofers in Walnut
Yes, re-roofing in Walnut requires a city permit, and hillside or wildfire-adjacent properties may need additional fire-rated assembly documentation. We pull permits and handle inspections as part of the job, so you do not have to deal with the city directly.
Most Walnut inspections are scheduled within three to five business days. If you have an active leak after a storm, we prioritize water-intrusion calls because the damage compounds quickly. Call (833) 467-4901 and we will get you on the schedule.

What Walnut Customers Say
"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."
— Bethany Rhodes"Storm took part of the ridge off at night. They tarped it the same evening so the rain didn't get in, and did the real repair the following week."
— Mark Gallagher"Fixed the leak and it has stayed fixed through a wet winter. Scheduling the initial estimate took about a week and a half, so they're clearly busy."
— Andre Prince
