Fast, Reliable Roofing Company Across Orange County
A full roof replacement in Orange County on a standard 1960s or 1970s tract home typically runs between $14,000 and $28,000, depending on square count, decking condition, and whether your home sits in a wildfire zone that requires Class A materials. Repairs are usually $450 to $1,800. The number to call is (559) 258-5703, and the price goes on paper before any work starts.
We work in Orange County every week, from Santa Ana ranchers to the hillside streets of Anaheim Hills. The housing stock here has a rhythm to it, and after enough years walking roofs across the county, you learn what a 1972 tract roof sounds like underfoot before you ever lift a shingle. That matters when a bad flashing job in a Santa Ana wind can mean a $9,000 ceiling repair six months later.
Our Roofing Company crews are background-checked, uniformed, and answer to a written standard, not a sales script. Travis Oakley runs this office, and he’s the one who makes sure the crew shows up inside the promised window and the price doesn’t move at the door.
Why Brennan Roofing Co Orange County Is Orange County’s Preferred Roofing Company Company
We’ve built our reputation in Orange County on a simple practice: the number you sign is the number you pay. No allowance games, no “well, the decking was worse than we thought” surprise at the end of the week. If we open a roof on a 1968 tract home in Orange and find rotted decking, that discovery has a written price attached before a single new board goes down.
The area’s roofs fail in predictable ways. Intense UV exposure cooks the binders out of composition shingles faster here than it does closer to the coast in Long Beach. Santa Ana winds lift edges and drive rain sideways under flashing that looked fine in August. By the time a homeowner notices a ceiling stain in December, the leak has usually been active for weeks, because the county’s dry months mask small failures until the first real storm.
Our crews know the difference between what a Yorba Linda roof needs and what a Costa Mesa roof needs, and that local knowledge gets written into every estimate. We don’t run two teardown crews and hope the B-team figures it out. Every technician is background-checked and in uniform, and every job is covered by the 365-Day Done Right Promise, in writing, for a full year.
Styles & brands we work with






Residential Roofing in Orange County
Residential Roofing in Orange County means something specific: you’re likely on a tract home built between 1950 and 1980, and the roof you’re replacing has been end-of-life for longer than you think. The original 25-year composition shingle didn’t make it to 25 years here. UV breaks down the asphalt, Santa Ana winds loosen the granule bond, and by year 20, most of these roofs are shedding material into the gutters. A full tear-off and re-roof with an architectural shingle in Orange County generally lands between $14,000 and $28,000, with the biggest variable being decking replacement, which adds $2.50 to $4.00 per square foot when needed.
Decking Inspection Before Any Numbers Are Final
Before we write your contract, we get into the attic and check what’s actually under the shingles. Orange County tract builders in the 1960s and 1970s used whatever sheathing was cheap at the time, and four decades of minor leaks means some of it is rotted. We write a decking allowance into the contract before tear-off. If the rot is worse than the allowance, the extra cost is priced and approved in writing before we touch it. Nothing gets charged without your signature.
Class A Fire-Rated Systems for Foothill Communities
If your home is in Anaheim Hills, Yorba Linda, or anywhere east of the 55 with brush on the ridgelines, your re-roof must meet Class A fire assembly requirements. That means fire-rated underlayment, ember-resistant ridge vents, and usually a standing seam or Class A architectural shingle. We document every layer with photos and keep the cut sheets from GAF, IKO, and Atlas so your insurance inspection goes through without a second request.
Roof Maintenance in Orange County
Roof Maintenance in Orange County isn’t a luxury; it’s how you avoid the single biggest roofing expense this county produces: deferred failure. Because rainfall here comes in bursts, a roof can degrade for eight months a year without anyone noticing. Then a December atmospheric river rolls in and a pinhole leak becomes a flooded bedroom ceiling. A routine inspection and maintenance visit costs $250 to $450, and it catches the loose flashing, cracked pipe boot, or lifted shingle edge before it becomes a $2,400 emergency repair in the rain.
Annual Inspection Before the Rainy Season
We schedule maintenance inspections in September and October, before the first real storm. The inspection covers flashing at every penetration, valley conditions, ridge vent function, and decking moisture readings in the attic. You get a written report with photos, and we flag anything that needs attention in the next 12 months versus what needs it now. Homeowners in Orange County who do this every year rarely need a full replacement before year 30 on the roof, because the small failures get caught when they’re still small.
Maintenance for Master-Planned Tile Roofs
Newer Orange County communities, like the Mediterranean-style tract communities through Irvine and parts of Tustin, have tile roofs that people assume are maintenance-free. They’re not. Tile roofs fail at the underlayment, not the tile. We walk the roof and check for cracked tiles, failed mortar at the hips and ridges, and lifted underlayment from wind exposure. A tile roof maintenance visit is $350 to $500, and it’s a fraction of what a full underlayment replacement costs on a 4,000 square foot tile roof.
Trusted Brands We Service in Orange County
We install Atlas and IKO architectural shingles most often in Orange County, and we also work with Boral when a homeowner wants the concrete tile profile that matches a Mediterranean-style tract home. The brands matter because they determine how the roof performs in 90-degree UV and 60 mph Santa Ana gusts. We don’t stock every brand at once, but we keep common color blends and accessory parts for Atlas, IKO, and Boral roofs in our local inventory, which means when we need matching ridge caps or a specific vent color for a repair in Santa Ana or Orange, turnaround is measured in days, not weeks.

AfterCommon Roofing Company Problems We See in Orange County Homes
- Composition shingle roofs reaching end-of-life simultaneously. The county’s 1960s and 1970s tract housing boom means thousands of roofs with the same original shingle, installed the same way, failing at roughly the same time. We’re now replacing roofs on houses where the next-door neighbor’s roof has already been replaced twice.
- Santa Ana wind damage at rake edges and valleys. Wind doesn’t lift shingles evenly here; it finds the same weak points on every south-facing slope. Flashing that was never properly secured gets pulled away, and wind-driven rain works into the underlayment. We see this most in homes along the 91 corridor where the wind channels through the Santa Ana Canyon.
- Rotted decking from undetected leaks in dry months. A pinhole leak in May does no visible damage until November. Homeowners tell us the roof “never leaked,” but the decking in the attic tells a different story. Hidden rot is the single most common change order trigger in Orange County, and it’s why we inspect decking before the contract is written.
- Shiners and high nailing from low-bid crews. A shingle nailed outside the nailing line pops up within a year or two. A shingle nailed too high fails the wind warranty. We find rows of shiners on roofs that are only five years old, installed by crews chasing the lowest bid in Costa Mesa or Newport Beach, and now the homeowner is paying for a repair that should have never been needed.
Pricing for Roofing Company in Orange County, CA
A full tear-off and re-roof on an average 1,700 square foot Orange County tract home runs $14,000 to $28,000, with the final number driven by decking condition, roof complexity, and whether the home sits in a Class A fire zone. A straightforward repair, like replacing a worn pipe boot or resealing a valley, is $450 to $800. Larger repairs, such as a full ridge cap replacement or a 30-square patch on a low-slope section, fall between $1,200 and $2,800.

FAQs About Roofing Company in Orange County
Yes, if your home falls under the county’s current energy code. Orange County enforces California’s Title 24 Cool Roof requirements for most residential re-roofs in climate zones 8 through 14, which covers the vast majority of the county. What that means in practice: your new shingle or tile must meet a minimum solar reflectance and thermal emittance rating, and it must be documented on the permit. Some homeowners assume they can pick any dark shingle they like. If you’re in a wildfire zone, that’s doubly wrong, because dark roofs also absorb more heat and can worsen attic temperatures during Santa Ana conditions. We check the specific requirement for your address before we write the estimate, and the material we spec is the material that passes inspection.
Because Anaheim Hills and Yorba Linda sit inside California’s designated High Fire Hazard Severity Zones, and the building code there requires Class A roofing assemblies, which include ember-resistant vents. Huntington Beach and Newport Beach sit outside the zone, so the mandate doesn’t apply. But it’s not just a code difference. In a Santa Ana wind event, embers from a hillside fire can travel a mile and land on your roof. A standard box vent or ridge vent with no ember mesh lets those embers drop into your attic, and then the roof doesn’t matter because the fire started underneath it. We install ember-rated intake and exhaust vents in every foothill re-roof, and we document them for your insurer.
Most 1960s and 1970s single-story tract homes in Orange County sit between 18 and 24 squares, with a square equaling 100 square feet of roof area. Two-story homes run higher, usually 26 to 34 squares, because the roof pitch is often steeper and the footprint larger. The square count is the starting point for every estimate, and we measure it from the roof itself, not from a satellite image, because satellite measurements miss eaves, porches, and transitions. If a bidder gives you a “job price” without showing you the square count, ask for it. That’s how you know whether you’re comparing the same roofs.
On an Orange County tract home, you need a full tear-off, not a reroof-over. Reroofing over an existing shingle layer is legal in a few specific cases, but it’s a bad idea on roofs this age because you’re hiding whatever is happening to the decking underneath. In Orange County, that decking is often original to the house, and if it’s been slowly rotting from minor leaks that never showed, you’d be putting a new roof on top of a failing structure. A tear-off costs roughly $1,500 to $3,000 more than a reroof-over, but you get a full decking inspection, code upgrades at the roof-to-wall transitions, and a warranty that actually holds. Reroof-over is a warranty killer, because most shingle manufacturers won’t stand behind a roof installed over old material.
A standard shingle gets four nails per shingle, spaced along the nailing strip. The 130 mph wind rating requires six nails per shingle, placed precisely within the manufacturer’s specified nailing zone, plus a closed-corner sealing strip and a wider overhang at the eaves. The nailing pattern is the part that most determines whether your roof survives a Santa Ana wind event or loses whole courses of shingles. On south-facing slopes in Orange County, where the wind hits hardest, we spec the six-nail pattern on every architectural shingle installation. It adds about $300 to $500 to the average job and it’s the difference between a roof that holds and a roof that the insurance adjuster photographs after the first 60 mph gust.
