Fast, Reliable Roof Repair Across Orange County
Roof repair in Orange County usually costs between $350 and $1,400 for the most common jobs, with full underlayment replacement on an older Spanish tile roof running $4,500 to $9,500 depending on square footage and decking condition. That is an honest range, not a teaser rate. We are Tilehurst Roofing Orange County, part of the Kingswell family of roofing companies founded in 2000, and we have spent enough time on tract-home roofs in Mission Viejo, Irvine, and Lake Forest to know exactly what fails here and what it costs to fix before Santa Ana season turns a small crack into a soaked ceiling. Call (559) 295-5445 and a live person answers. Every single time.
Why Tilehurst Roofing Orange County Is Orange County’s Preferred Roof Repair Company
We are not the cheapest bid in Orange County, and we will not pretend to be. What we are is the company local homeowners call after the cheap bid no-showed or finished a repair that leaked again in three months. Our repair crews know the difference between a 1970s Anaheim composition shingle roof and a 1990s Irvine concrete S-tile roof, because we have opened both up and seen what hides underneath. Every Tilehurst Roofing location operates under the Kingswell Guarantee, and this one is led by Greg Holloway, who holds his crews to the standard our customers read about before they ever pick up the phone.
Three things set us apart across Orange County. First, a written price lands in your hands before any work starts. Not an estimate sheet with fine print. A line-item price. Second, every repair carries a written guarantee, delivered before the crew leaves your property. Third, if that repair fails inside the guarantee period, we return and correct it at no charge under the 365-Day Done Right Promise. That is a full year of documented accountability. We answer our own phone 24/7, and the person who picks up is a real person, not a callback queue.
Styles & brands we work with
Flat Roof Repair in Orange County
Flat Roof Repair in Orange County typically runs $400 to $1,200 for patching a leak around a vent, seam, or drainage point, though full resurfacing of a larger flat section can reach $3,500 to $6,000. Orange County flat roofs show up most often on 1970s and 1980s additions, enclosed patios, and some Fullerton and Anaheim ranches with low-slope rear sections. The heat here is relentless, and a dark flat roof surface in an Irvine summer can hit temperatures that cook standard patch material in a few years. We use reinforced, UV-stable membrane materials and high-bond adhesives that hold up to the inland heat without cracking or peeling away from the roof deck.
Seam and Vent Boot Failures
The most common flat roof leak starts at a seam or a plumbing vent boot, not in the field of the roof itself. On Orange County flat roofs, dried-out caulking and cracked rubber boots around vent pipes let water in during the first real rain after a dry summer. We replace the boot, reseal the seam with a heat-rated compound, and flash the penetration with metal that will not curl in the sun.
Ponding Water and Drainage Corrections
Older flat roofs in Orange County often have a slight sag that lets water pond after a storm. Ponding accelerates membrane breakdown and finds every loose seam. We correct the slope where practical with a tapered fill layer, then apply a new membrane over the corrected surface so the water actually drains instead of sitting there.
Shingle Roof Repair in Orange County
Shingle Roof Repair in Orange County usually costs $350 to $950 for a straightforward replacement of a handful of damaged asphalt shingles, while a valley repair or flashing replacement on a shingle roof runs $500 to $1,400. Orange County neighborhoods like Fullerton, Mission Viejo, and parts of Anaheim are dense with composition shingle roofs from the 1970s through 1990s, and the shingles are now brittle from decades of UV exposure. Cracked, curled, or missing shingles let water reach the decking underneath, and by the time you see a ceiling stain, the decking has usually been wet for weeks.
Blown-Off and Slipped Shingles
Santa Ana wind gusts are hard on aging shingle roofs across Orange County. Shingles with dried-out adhesive strips or loose nails get lifted, sometimes torn clean off. We replace the damaged shingles, re-secure the surrounding courses, and check the ridge cap and drip edge for wind damage in the same visit.
Valley and Flashing Leaks
Valley metal on older Orange County shingle roofs is often thin and rusted through. When water runs down the valley during a storm and finds a crack in the metal, it travels along the decking and shows up far from the actual leak. We replace the valley metal, inspect the underlayment beneath it, and reseal the shingles along both edges so the repair holds through multiple rainy seasons.
Trusted Brands We Service in Orange County
We are not a captive brand shop. Tilehurst Roofing Orange County installs and repairs roofing from seven major manufacturers, and for Orange County homes we most often work with GAF, CertainTeed, and Owens Corning shingles, plus IKO for specific profiles. That means the product gets matched to your home, your HOA’s approved palette, and your budget, not to whatever happens to be in the truck. We stock common profiles and colors locally for Orange County customers, so a small repair does not wait on a week-long special order. If your HOA requires a specific color or profile, we source it and handle the paperwork.
Common Roof Repair Problems We See in Orange County Homes
- Concrete tile roofs leaking with no visible broken tile. Original asphalt-saturated felt underlayment on 1960s through 1990s tract homes dries out and cracks under decades of UV and heat, so water seeps through even when the tile above looks fine. Many Mission Viejo and Irvine S-tile roofs are due for underlayment replacement every 20 to 30 years.
- Santa Ana uplift damage on tile and shingle edges. Wind gusts lift unsealed tile edges and tear brittle shingle corners. Tiles that slap back down often crack at the leading edge, leaving a path for the next rain.
- Salt-air corrosion on coastal flashings and fasteners. In Newport Beach and Laguna Beach, galvanized flashings and fasteners rust through within a decade, staining tiles and leaking at chimneys, valleys, and penetrations. We replace them with stainless steel or copper so they do not rust again.
- HOA-driven repair restrictions that slow down emergency work. Irvine, Mission Viejo, and many Lake Forest communities require approval before any visible roof change, including tile and shingle color. We are used to the approval process and can match existing materials so the repair passes on the first submittal.

FAQs About Roof Repair in Orange County
You look for three things: cracked or powdery felt visible at the roof edges, tiles that have shifted or settled in rows, and water stains on the underside of the roof deck visible from the attic. If your home was built between 1965 and 1995 and the roof still has its original underlayment, it is almost certainly past its service life, and a proactive lift-and-inspect is the way to catch it before a leak takes out your ceiling. Call (559) 295-5445 and we will inspect it for free and give you a written condition report.
Yes, in most Irvine and Mission Viejo communities, any visible change to the roof, including replacing broken tile or changing underlayment that alters the roof profile, requires HOA approval first. We handle the application for you, including color and profile matching documentation, so the repair does not stall in committee. Our crews have worked with the major Orange County HOA management companies and know what they ask for.
Salt air corrodes metal flashings and fasteners year-round, not just in wet weather. On a Newport Beach home, galvanized flashing around a chimney or valley can rust through in under a decade, and once it does, even a light marine-layer drizzle sends water through the gap. We replace corroded flashings and fasteners with stainless steel or copper on coastal Orange County homes, which holds up to salt air for decades.
A roofing square is 100 square feet of roof surface, and repair quotes should clearly state how many squares of material will be replaced or resurfaced. Ask your roofer to write the number of squares into the line items, then measure your roof area roughly so you are comparing equal scopes. A quote that says “fix leak” without square count is not a quote you can hold anyone to. Ours always includes square counts, material removed, and material installed.
Yes, we match existing concrete tile color and profile on every repair, including Laguna Beach homes with custom or discontinued profiles. We pull a sample from your roof, match it against current manufacturer catalogs and local salvage options, and submit the match to your HOA if required. The goal is a repair you cannot find from the ground. Call (559) 295-5445 and we will come out, identify the tile, and give you a written price for the matched repair.
What Opening Up an Orange County Tile Roof Actually Turns Up
Orange County’s Spanish-style concrete tile roofs, common on tract homes built from the 1960s through 1990s in Mission Viejo, Irvine, and Lake Forest, require underlayment replacement every 20 to 30 years, not because the tile fails but because the original asphalt-saturated felt underneath dries out and cracks under intense UV and Santa Ana heat. The tile on top looks fine. The waterproofing underneath is gone. When we opened up a 1987 Lake Forest home’s concrete S-tile roof on Trabuco Road, the decking under the cracked tiles showed water stains from failed underlayment, and the galvanized flashing at the chimney had corroded from salt air blown inland. We replaced the decking, installed a synthetic underlayment with a high-temperature rating, swapped the flashings to stainless steel, and re-bedded the tiles, all before the fall Santa Ana season arrived. That is the kind of surprise that shows up on older Orange County roofs, and the reason we inspect before we quote. Under the Kingswell Way, we say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if any of it fails inside the guarantee period.
