Roof replacement in Irvine costs between $11,500 and $26,000 for a standard single-family home, with most architectural shingle tear-offs in the $14,000 to $19,000 range. That includes removal of the old roof to the decking, new underlayment, shingles, flashing, and haul-away. We’re the roofing team Irvine homeowners call when they want a written price before any work starts, a trackable arrival time, and photo documentation of everything we do. Reach us at (325) 246-5075 to schedule a free estimate.
Irvine is not a simple roofing market. Homes here were built in waves, from the 1970s tracts near University Park to the newer developments in Portola Springs and the Great Park neighborhoods. Some have flat sections over patios. Others have steep multi-plane roofs that punish lazy measurement. We know the difference because we’ve walked hundreds of these roofs, and we scope every job in person before putting a number on paper.
Key Takeaways:
- Most full roof replacements in Irvine run $11,500 to $26,000 depending on size, pitch, and decking condition.
- Irvine requires a re-roof permit before tear-off starts. We pull it, not you.
- The City checks more than shingles at inspection: underlayment, fire-rated assembly (in wildfire-adjacent zones), and structural decking all get looked at.
- Every job comes with a written price before work begins, before-and-after photos, and a 365-Day Done Right Promise in writing.
Why Crestview Roofing Is Irvine’s Preferred Roof Replacement Company
Dylan Pace founded Crestview Roofing in 2000, and the company has operated on one principle since day one: the number on the written estimate is the number on the final invoice. That matters more in Irvine than almost anywhere else. Homeowners here are engineers, finance people, and project managers. They read the fine print. They notice when a quote is vague, and they don’t appreciate surprises.
Our Irvine customers see exactly who is arriving, when, and what the job will cost. The Relay Standard governs every project: a written price before any work begins, live trackable arrival times, before-and-after photo documentation, and a digital invoice sent by text. Dispatch and scheduling are coordinated from the brand’s Los Angeles office, and crews serve Irvine locally.
We have replaced roofs on homes throughout Woodbridge, Northwood, Turtle Rock, and the Great Park area. Homeowners call us because we answer the phone with a live person, 24/7, and because our technicians arrive background-checked and in uniform. You know who is pulling up before they step out of the truck.
Asphalt Shingle Roof Replacement in Irvine
Asphalt Shingle Roof Replacement in Irvine remains the most common full roof job we do, and for good reason: architectural shingles hold up to the long dry season, the rare but intense winter rain, and the afternoon sun that bakes south-facing slopes in Northwood and Westpark. A typical asphalt shingle tear-off and replacement on a 2,200-square-foot Irvine home costs between $13,000 and $19,000, depending on decking condition, roof pitch, and the number of penetrations.
The job starts with pulling the Irvine re-roof permit, then removing the old shingles, underlayment, drip edge, and starter strip down to the decking. We replace any rotted or delaminated plywood or OSB before laying new synthetic underlayment, installing the shingle system, re-flashing all penetrations, and finishing with a ridge vent if the home is set up for continuous ventilation. Our Roof Replacement in Irvine work always ends with a job site that is clean enough for a homeowner to walk barefoot, or close to it.
Decking and Underlayment
Irvine homes from the 1980s and 1990s often have plywood decking that has baked under decades of heat. When corners are cut and new shingles go over failed underlayment, the decking rots underneath and nobody sees it until the roof sags or leaks. We replace bad decking as we find it, and we show you photos of every sheet before it gets covered.
Architectural Shingle Upgrades
Standard three-tab shingles are legal to install in Irvine, but we recommend architectural shingles for almost every homeowner. They carry better wind ratings, look better on the multi-plane roofs common in Turtle Rock and Woodbridge, and the cost difference is usually $1,200 to $2,500 on a full roof. Given that an Irvine roof replacement is expected to last 25 years or more, that upgrade pays for itself.
New Roof Installation in Irvine
New Roof Installation in Irvine typically falls into two buckets: a roof on an addition or new construction project, or a full replacement framed as a new installation after structural work. New construction roofs in Irvine run $17,000 to $35,000 depending on square footage, roof complexity, and spec level, and they require the same permit process as any other roof work.
For homeowners adding a second story, a great room, or an ADU in neighborhoods like University Park or Portola Springs, the roofing scope gets tied into the larger project. We coordinate directly with the general contractor or work directly for the homeowner, and we make sure the roof package meets the City of Irvine’s current code requirements before the inspector shows up. If the property sits in a wildfire-adjacent zone on the eastern edge of Irvine, the Class A assembly documentation is checked at inspection, not just on the permit submittal.
Roof Decking for New Construction
New construction gives us a clean deck to work from, which means fewer change orders and a tighter installation timeline. We prefer Huber ZIP or similar engineered sheathing systems when the budget allows, because they integrate the water barrier directly into the deck. That eliminates a failure point on the exact day the roof is finished.
Flat Roof Sections
Many Irvine homes have flat or low-slope sections over patios, balconies, and sunrooms. These areas get a modified bitumen or TPO system, not shingles, and they cost $9 to $14 per square foot to replace. We inspect every flat section during a full roof replacement, because a leak at a patio roof intersection is one of the most common callbacks in Irvine.
Trusted Brands We Service in Irvine
We stock and install manufacturer-backed materials from GAF, CertainTeed, and Owens Corning, which means parts are available quickly for Irvine jobs and the warranties are real. GAF Timberline HDZ is our most common architectural shingle in Irvine because it hits the wind ratings and fire ratings the city looks for. CertainTeed Landmark is another strong option when homeowners want a specific color match, and Owens Corning Duration gives us flexibility on steep-pitch homes in Turtle Rock and Northwood. We are factory-trained on each system and can discuss the differences honestly before you commit.
Common Roof Replacement Problems We See in Irvine Homes
- Skipping the tear-off. Some roofers layer new shingles over old ones to save a day’s labor. Irvine’s inspection process during re-roof permits will flag this, and it hides soft decking that later causes sagging and leaks.
- Under-scoped square counts. Quotes built from satellite measurements regularly miss valleys and penetrations on the complex multi-plane roofs common in Woodbridge, Northwood, and Turtle Rock. Square count changes the price materially.
- Failed underlayment from 1990s-era construction. The original felt or synthetic underlayment on many Irvine homes has outlived its intended service life. Shingles look fine from the street; the waterproofing layer underneath is done.
- Permit missteps. Irvine requires the re-roof permit to be pulled before tear-off. Homeowners who let a roofer start work first face a stop-work order and a corrective inspection that adds weeks to the job.
Pricing for Roof Replacement in Irvine, CA
A standard architectural shingle roof replacement in Irvine runs from $11,500 to $19,000 for most single-family homes between 1,800 and 2,800 square feet. Larger homes, steep pitches, and complex rooflines push that to $22,000 to $35,000. The three cost drivers that actually move the needle are decking replacement (usually $2,500 to $6,000 when significant rot is found), fascia and gutter-line repairs ($800 to $2,400), and square count corrections after an on-site measurement. Call (325) 246-5075 for a free estimate, and we will walk the roof with you, show you photos of what needs replacing, and put the full number in writing before you sign anything.

FAQs About Roof Replacement in Irvine
Yes, the City of Irvine requires a re-roof permit before any tear-off begins, and Crestview Roofing pulls it on your behalf as part of the job. The permit is not a formality. A 2017-or-later roof tear-off without matching documentation can trigger mandatory structural verification before a new roof replacement permit is issued, and homes in wildfire-adjacent zones on the eastern edges of Irvine get their Class A assembly documentation checked at inspection. Call (325) 246-5075 and we will walk you through the exact permit path for your specific property.
Irvine inspectors check the decking condition, the underlayment type and installation, the fire-rated assembly (when applicable), and the final roof system after nailing. They also verify that the permit matches the actual work done. If we find decking rot or other issues during tear-off, we document it with photos and give you a written change order before proceeding, so the inspection never gets failed for undocumented work.
Most Irvine roof replacements take 5 to 10 business days from permit issuance to final inspection, assuming standard weather and no structural surprises. The tear-off and installation usually run 2 to 4 days, and the inspection is scheduled within a few days after that. Homes with complex multi-plane roofs, like those in Woodbridge or Turtle Rock, add a day or two to the install.
The two things that change the price after tear-off are hidden decking rot and fascia or gutter-line damage that only becomes visible once the old roof is removed. On most Irvine homes this adds $2,500 to $6,000 on the decking side and $800 to $2,400 for fascia work. We document every sheet of replaced decking with photos and get written approval before we buy a single piece of lumber, so there are no vague charges at the end.
Yes, many architectural shingles carry a 130 mph wind rating when installed per manufacturer spec, and it does matter in Irvine because Santa Ana wind events can produce sustained gusts that peel standard three-tab shingles. The rating only holds if the shingles are nailed correctly. We follow the manufacturer’s nailing pattern and count, every time, on every roof.
