Fast, Reliable Roofing Company Across Orange
Roofing work in Orange comes down to one thing: knowing what these mid-century tract homes hide under the shingles. Most roofs in Orange were built between the 1950s and 1970s, and a lot of them are at the end of their life. We’re Brennan Roofing Co Orange County, and we’ve torn off enough of them to know that the real problems usually sit beneath the surface. When you call (559) 258-5703, you get a live person and a straight answer about what your roof actually needs.
We work under The Garrison Standard. That means written pricing before any work starts, background-checked uniformed technicians, and the 365-Day Done Right Promise in writing on every job. Orange roofs fail in predictable ways. We know what to look for before we touch a shingle.
Why Brennan Roofing Co Orange County Is Orange’s Preferred Roofing Company Company
Homeowners across Orange call us because we show up inside the promised window and put the price on paper before anything gets touched. No door-step surprises. No “we found something extra” once the roof is open. If a change order is needed, we price it and get approval before cutting anything.
Our crews know Orange’s housing stock. We know what a 1960s low-slope roof near the Plaza looks like when it’s finally given up. We know how Santa Ana winds lift worn composition shingles on Gless Street or Tustin Avenue. The Garrison Code applies every time: written price first, uniformed technicians on site, and if it’s not done right, we make it right free for a full year.
Travis Oakley runs our Orange County operation. He’s the person who makes sure the crew on your roof is the same one that was promised, with the same standard applied from the first tear-off to the final nail. That consistency is why Orange homeowners keep our number.
Styles & brands we work with






Roofing Contractor in Orange
Roofing Contractor work in Orange usually starts as a repair call and ends as a conversation about what the city will actually permit. We handle full tear-offs, replacements, repairs, and inspections, and we always start with what’s visible, then plan for what’s underneath. A typical roof repair in Orange runs $450 – $1,200. A full replacement on a mid-century tract home runs $11,000 – $19,000 depending on pitch, decking condition, and material choice.
Mid-Century Tear-Off and Replacement
Older Orange homes often have two layers of original composition shingles over 1×6 decking. When we open that up, the decking is frequently dry-rotted at valleys and eaves. We price decking replacement as a written allowance before the job starts, so the number doesn’t move on you mid-project.
Code-Triggered Upgrades
Once a permit is pulled on an older Orange roof, the city requires current fire-resistant and Title 24 cool-roof compliance. If your home still carries a grandfathered wood shake roof, a small repair can legally force a full replacement. We flag that before quoting, because nobody should pay for a patch that can’t legally happen.
Commercial Roofing in Orange
Commercial Roofing in Orange means flat and low-slope systems on aging office strips and retail buildings where water has been sitting in the same low spots for decades. We handle TPO, modified bitumen, and coated metal systems, plus the emergency repairs that come after a heavy winter rain finds a cracked parapet. Commercial repairs in Orange typically run $900 – $4,500 depending on membrane type and damage extent. Full commercial replacements run $8 – $15 per square foot.
Flat Roof Maintenance and Repairs
Most Orange commercial buildings have flat or low-slope roofs where ponding water is the main enemy. We inspect drains, scuppers, seams, and flashing, then write the repair scope so you know exactly what’s being done and what it costs before anyone goes up on the roof.
Tenant Fit-Up Roof Work
When a commercial space changes hands in Orange, we handle the roofing portion of the tenant improvement: curbs for new HVAC, penetrations for exhaust, and patching that actually ties into the existing membrane. Written pricing up front, no surprise add-ons once the work starts.
Trusted Brands We Service in Orange
We install GAF, CertainTeed, and Tamko systems regularly across Orange, and we stock common flashing and accessory parts locally so we aren’t waiting on a distributor when a repair window matters. When we quote a roof, we explain why a specific material fits the home’s pitch, exposure, and the homeowner’s realistic budget. The brand matters less than the installation standard, and ours is the same whether we’re laying Owens Corning or Boral. If you have a preference, we’ll price it and put it on paper.

AfterCommon Roofing Company Problems We See in Orange Homes
- Hidden decking rot under old composition shingles. Two layers of 1950s shingles hide punky 1×6 decking that won’t hold a nail. We find it before we install, and we write the replacement cost into the original contract as an allowance.
- Underlayment that failed years before the shingles did. The top layer can look acceptable while the felt has dry-rotted into paper. Nails sink, water gets in. This is the most common overlooked defect in Orange’s original tract roofs.
- Code-triggered replacement on grandfathered wood shake. East of the Plaza especially, a repair permit on an original shake roof forces a full tear-off to fire-resistant materials. Homeowners who expected a $600 patch find themselves looking at a full re-roof, which is why we identify this before quoting anything.
- Original drip edge left in place after a tear-off. Some crews re-use the old drip edge to save a few dollars. Orange’s current code requires upgraded flashing at eaves and rakes. We replace it as standard, not as an extra.

FAQs About Roofing Company in Orange
If the roof is still grandfathered and you do a minor repair without a permit, you might be able to replace a few shakes. But if the repair triggers a permit, Orange’s current code requires a full tear-off and replacement with fire-resistant materials. That means a small patch becomes a full re-roof by law. We identify this before we quote anything, so you aren’t surprised later.
Call (559) 258-5703 and we’ll tell you what your specific roof triggers before you spend a dollar.
Title 24 requires cool-roof rated materials on most low-slope residential replacements in Orange. That means a reflective surface that lowers heat absorption. We price compliant options from GAF, CertainTeed, and Tamko so you know exactly what the code-compliant choice costs from the start.
For an exact figure on your home, call (559) 258-5703 for a free written estimate.
A full re-roof includes tear-off of all existing layers, decking inspection and replacement where rotted, new underlayment, new drip edge and valley flashing, new roof-to-wall flashing, and installation of the shingle or tile system. On Orange’s older tract homes, we also write an allowance for hidden decking damage so the final number doesn’t move once the old roof comes off.

Yes. Higher-end architectural shingles from Tamko, GAF, and CertainTeed carry wind ratings up to 130 mph, which handles Orange’s Santa Ana wind events. We explain the rating differences plainly and price the options so you choose with real information, not marketing fluff.
Call (559) 258-5703 and we’ll walk you through what fits your roof and your budget.
Because most original Orange tract roofs already have two layers, and code doesn’t allow a third. Once a roof is opened for any permitted repair, the city requires current fire and Title 24 standards, which often makes overlay technically illegal on older homes. Tear-off is usually the only legal path, and we price it honestly from the start.
