Why Brennan Roofing Is Placentia’s Preferred Roofing Company
Placentia is not a generic Orange County suburb. The city holds one of the few dedicated historic preservation programs in North Orange County, and that changes how roofing gets done here. Old Town Placentia, around the Civic Center, is dense with 1920s Spanish Colonial Revival homes and Craftsman bungalows. Original clay tile and wood shakes on those roofs cannot simply be swapped for modern composite shingles. The Historic Preservation Commission reviews that work, and non-period-correct materials can stall a permit or trigger a compliance order. We know that before we walk the roof.
Our Placentia customers call us because a previous roofer no-showed, bid low and then raised the number at the door, or finished the job and left debris in the yard. Travis Oakley runs our work under the Garrison Standard: price on paper before any work starts, the same standard on every job, and a written guarantee for one full year. If a repair fails within that year, we return at no charge. That is not a slogan. It is in writing.
Background-checked, uniformed technicians do the work. Phones are answered by a live person around the clock, no voicemail queue. For Placentia homeowners who have been burned before, that is the difference between a roofer you watch from the window and a roofer you can let onto your roof without second-guessing it.
Free Roof Estimate in Placentia
A Free Roof Inspection in Placentia means we walk the roof, check the flashing, decking, underlayment, and drip edge, and hand you a written line-item price before we ask for a signature. No estimate ever starts without boots on the roof, not a satellite image and a guess. In Placentia, that inspection matters more than in most cities because so much of the housing stock is older and so much of it sits under clay tile that has been there since the 1950s or earlier.
What the Estimate Covers
We document everything with photos. Flashings, valleys, chimney penetrations, pipe jacks, ridge lines, and the condition of the decking beneath the shingles or tile. If we see a problem in the attic, we note it. The price goes on paper before any work starts, and it does not move at the door.
When to Schedule One
If your roof is past 15 years old on asphalt shingles, or past 25 on tile, book an estimate before the next Santa Ana season. Wind events lift tiles and shingles, and the hot inland sun degrades underlayment faster than most Placentia homeowners expect. A written estimate now is cheaper than a leak after the first real rain.
Roofing Contractor in Placentia
A Roofing Contractor in Placentia who works on older homes has to understand the Historic Preservation Commission review process in Old Town, and ours does. That is not a marketing line. We have pulled tile off a 1920s Spanish Colonial Revival near the Old Town Civic Center and found the original skip sheathing rotted through, failed flashing around a chimney sealed with mastic instead of new metal, and a valley that had been leaking for years. We priced the decking and flashing replacement in writing before proceeding, and we reinstalled period-appropriate tile so the roofline matched the original design.
Roof Repair
Repairs in Placentia typically run $380 – $1,150. Most common issues we see: cracked or slipped clay tiles, rusted flashing, failing underlayment on older asphalt roofs, and open valleys that have been ignored for years. We fix the leak and the cause of the leak, not just the first visible symptom.
Roof Replacement
Full replacements in Placentia run $9,500 – $24,000, depending on the home’s size, pitch, and material. On historic homes, period-correct clay tile pushes that number toward the upper end and requires HPC review. On 1950s and 60s tract homes, a full tear-off down to the decking is usually the right call, since the original underlayment was never designed for 60-plus years of UV exposure.
Trusted Brands We Service in Placentia
We install materials from GAF, CertainTeed, and Owens Corning, among other manufacturer lines, and we explain the difference between them plainly so you can choose with confidence. For Placentia’s Spanish Colonial Revival homes, that often means matching clay tile profiles from manufacturers who still produce period-appropriate shapes. For mid-century tract homes, architectural asphalt shingles from GAF or CertainTeed offer the best balance of cost, lifespan, and wind resistance against the Santa Anas. We stock common flashing, underlayment, and ridge components for fast turnaround on repairs across the city.
Common Roofing Company Problems We See in Placentia Homes
- Historic tile failures in Old Town: Original clay tiles crack and shift over decades, and the skip sheathing underneath rots from trapped moisture. A modern composite shingle patch cannot pass Historic Preservation Commission review, so the repair has to respect the original profile and material.
- Failed underlayment on 1950s-60s asphalt roofs: The original felt underlayment degrades from decades of inland heat and UV exposure, even though the shingles on top may still look serviceable. Leaks show up at the valleys and around penetrations first.
- Santa Ana wind damage: Sustained winds lift tiles and shingles along ridge lines and eaves on homes throughout Placentia, especially on the more exposed tracts near the 57 freeway corridor. Lifted edges let water in and accelerate underlayment breakdown.
- Rusted flashing on older tract homes: Chimney and pipe-jack flashing on 1960s-era homes has often outlived its lifespan. When it rusts through, the leak travels into the attic before it shows on the ceiling.
Pricing for Roofing Company in Placentia, CA
Here are the numbers we quote in Placentia. Roof repair: $380 – $1,150. Full roof replacement: $9,500 – $24,000, with historic tile roofs in Old Town at the upper end and standard architectural shingle re-roofs on mid-century tract homes at the lower end. What moves the number: roof pitch, number of stories, tile versus shingle, decking condition, and whether the home requires Historic Preservation Commission review. We do not bid by shingle count alone. The written estimate includes an allowance for decking, flashing, and drip edge replacement where the existing roof is at the end of its lifespan, so the number you sign is the number we honor.

FAQs About Roofing Company in Placentia
Yes, in most cases. Old Town Placentia sits within a designated historic district, and re-roofing a Spanish Colonial Revival there typically triggers Historic Preservation Commission review. The commission cares about material, profile, and visual character. Swapping original clay tile for modern composite shingles can get a project denied or stall it mid-permit. We photograph the existing roof, identify the original material, and help you prepare the submittal before any work starts. Call (361) 320-9467 and we’ll walk you through it.
Rotted decking, failed underlayment, rusted flashing, and open valleys that were never properly sealed. On 1920s homes, original skip sheathing is often deteriorated. On 1950s-60s tract homes, the original underlayment has usually outlived its lifespan even if the shingles look fine. That is why we inspect the attic and the roof deck before quoting, and why the estimate includes written allowances for what the tear-off is likely to expose. The number goes on paper before work starts.
We write allowances into the contract for decking, flashing, and drip edge replacement based on what the inspection shows before the tear-off. If we open the roof and find rot beyond the allowance, we stop, document it with photos, and price the additional work in writing before we proceed. Nothing is done without your signature. That is the Garrison Standard, and it is why our Placentia customers do not get surprise change orders. Call (361) 320-9467 for a free estimate.
The City of Placentia requires permits for re-roofs, and insurance companies increasingly require permit documentation before they will pay on a claim. On historic homes in Old Town, the Historic Preservation Commission review is an additional step. We pull the permit, coordinate the inspection, and handle the paperwork as part of the job. You get a written price before any work starts, and the permit is part of that price.
Yes. Period clay tile runs higher upfront and costs more per repair because individual tiles are heavier, more fragile, and must match the existing profile. But a properly maintained clay tile roof can last 50 to 100 years, which no asphalt shingle will do. For a historic Placentia home, the HPC requirement usually makes the decision for you. For a standard tract home, architectural shingles from GAF or CertainTeed are the more practical choice. Call (361) 320-9467 and we’ll give you honest numbers for both.
