Trusted Roofing Company for Orange County Homeowners
Roofing in Orange County carries a specific set of demands. Coastal salt air along the 5 from Dana Point up through Newport Beach, intense UV exposure in Tustin and North Tustin, and the occasional heavy rain system that stalls over the Santa Ana mountains all punish a roof differently. We see the results up close: premature granule loss, corroded flashing, dry-rotted decking that crumbles when you walk across it. Brennan Roofing Co Orange County fixes and replaces roofs with a written price before any work starts, and every job is backed by the 365-Day Done Right Promise in writing. Call (559) 258-5703 and a live person answers, 24/7.
Our technicians are background-checked, uniformed, and dispatched from our Roofing Company in Santa Ana right here in Orange County. Travis Oakley runs the operation with one rule: the price goes on paper before the first ladder goes up, and that price does not move at the door.
Roofing Contractor
Roofing Contractor means a state-licensed professional who handles roof installation, replacement, repair, and inspection – not a handyman who does roofs on the side. You need one whenever a roof problem goes beyond basic debris clearing: missing shingles, water stains on ceilings, visible sagging, or a roof past the 20-year mark in Orange County sun. We handle all of it under The Garrison Standard, with a full-year written guarantee. Typical shingle roof repairs in this market run $350 to $1,200 depending on scope. Full replacements for a 1,800-square-foot Orange County home generally land between $14,000 and $22,000.
Licensed, Uniformed, Accountable
Every technician who touches your roof is background-checked and arrives in uniform. That’s not a marketing line – it’s part of The Garrison Code, the operating discipline our location agreed to follow. You’ll know exactly who is on your roof and what they’re accountable for.
What a Contractor Inspection Covers
We inspect flashing, underlayment, decking, drip edge, and ventilation, then tell you what needs work now and what can wait. You get the findings in plain English with a written repair quote attached. No pressure, no mystery.
Styles & brands we work with
Commercial Roofing
Commercial Roofing covers flat and low-slope roof systems on retail buildings, offices, warehouses, and multi-tenant properties across Orange County. It’s different from residential work: different materials, different drainage logic, different failure points at seams and penetrations. Commercial roof leaks in Costa Mesa strip malls or Placentia industrial parks usually appear first around HVAC curbs, pipe penetrations, or pooled-water zones. Repair costs for commercial membrane work in this area typically range from $800 to $4,500 depending on the membrane type and damage extent. Full commercial replacements run $6.50 to $11 per square foot installed.
Low-Slope Expertise
We work with TPO, PVC, and modified bitumen systems, and we map drainage before doing anything else. A flat roof that doesn’t shed water correctly will fail again no matter what membrane goes on top. Our commercial work starts with the roof’s pitch and flow, not just its surface.
Tenant and Landlord Coordination
We schedule commercial work around your tenants’ hours and provide written documentation for property records. You’ll know the price, the timeline, and the warranty terms before we order a single roll of membrane. That’s the only way we bid commercial jobs.
Metal Roof Installation
Metal Roof Installation means installing standing seam, corrugated, or stone-coated steel panels over your home or commercial building. In Orange County, metal makes strong sense along the coast, where salt air eats conventional shingles faster than inland areas, and in high-sun zones like Laguna Niguel and Aliso Viejo where heat reflectance matters. Metal installation in this market typically runs $14 to $26 per square foot installed for standing seam. A 1,800-square-foot home lands between $25,000 and $47,000 before any decking or structural repairs.
Stone-Coated Steel Options
For homeowners who want metal’s longevity without the industrial look, we install stone-coated steel systems from Boral. These panels carry the appearance of tile or shingle with a 50-year material lifespan and dramatically less weight than concrete tile.
Standing Seam for Coastal Homes
Standing seam panels from Atlas handle salt air without the corrosion issues that plague exposed fasteners on cheaper metal systems. We install hidden-fastener profiles with the proper underlayment beneath, which matters more than the panel itself in a marine climate.
Residential Roofing
Residential Roofing covers everything from single-family homes in Orange and Tustin to townhomes and small multi-family buildings anywhere in Orange County. You need it when your roof is leaking, when shingles are curling or losing granules into gutters, or when you’re buying or selling and a roof certification is required. Shingle roof replacement on a typical Orange County home runs $14,000 to $22,000. Spot repairs run $350 to $1,200. Tile roof repairs – common in older Santa Ana and Orange neighborhoods – run $600 to $2,400 depending on how many tiles and whether underlayment is involved.
Shingle and Tile Systems
We install architectural shingles from IKO and Tamko as well as concrete and clay tile systems. The right material for your home depends on pitch, exposure, and HOA requirements. We explain the trade-offs in plain language before you commit to anything.
Attic Ventilation Corrections
A large share of the failed residential roofs we see in Orange County didn’t fail because of shingle quality. They failed because the attic couldn’t breathe. We check intake and exhaust ventilation on every residential job and correct it as part of the replacement, because a hot attic shortens the life of any roof system by years.
Roof Maintenance
Roofing Company Maintenance Checklist for Orange County Homeowners starts with scheduled upkeep that prevents small problems from becoming water intrusion events: clearing debris, checking flashing and sealant, inspecting pipe boots, and documenting the roof’s condition. Orange County homeowners should have this done at least once a year, and twice a year if you’re within three miles of the coast in Newport Beach or Laguna Beach where salt spray accelerates fastener corrosion. A maintenance visit with a written condition report runs $195 to $450 for most homes in Orange County. If we find a problem and repair it, the repair itself carries the full-year guarantee.
Annual Inspections with Written Reports
Every maintenance visit ends with a written report and photographs. You’ll see exactly what we saw, what we fixed, and what’s likely to need attention in the next 12 to 24 months. That record matters when you sell, and it matters when you budget.
Flashing and Sealant Checks
The failure points on any Orange County roof are the transitions: where the roof meets a wall, a chimney, a skylight, or a vent pipe. We test these areas on every maintenance visit and re-seal or re-flash before water gets a path inside. Waiting until you see a ceiling stain is the expensive way to maintain a roof.
Roof Coating
Roof Coating is a liquid-applied membrane that seals and protects a low-slope or flat roof, usually a commercial or multi-family building, without tearing off the existing surface. It’s the right call when a flat roof is aging but still structurally sound, when you need to extend its service life five to twelve years without the cost of a full replacement. Coating in Orange County runs $3.50 to $7 per square foot applied, so a 2,000-square-foot flat roof lands between $7,000 and $14,000. That compares to full replacement at $13,000 to $22,000 for the same footprint.
Silicone and Acrylic Systems
We apply silicone coatings for areas with pooling water – common on older Orange County warehouses and carport decks – and acrylic for sloped metal roofs that need reflectivity more than waterproofing. The material choice depends on drainage, not preference. We’ll tell you which applies and why.
When Coating Beats Replacement
If a commercial roof is leaking at seams but the insulation isn’t saturated and the decking is sound, coating often makes more financial sense than replacing. We inspect the roof’s underside and core samples before recommending coating. If it’s not a fit, we’ll say so and quote replacement instead.
Free Roof Estimate
Free Roof Estimate means we come out, inspect your roof, and put a written price in your hand before any work starts – at no charge, no obligation. You need one anytime a roofer’s number seems vague, anytime an insurance adjuster’s report seems low, or anytime you’re comparing bids for a replacement. Every Brennan Roofing Co Orange County estimate includes line-item pricing, not a single bottom-line number. You’ll see exactly what you’re paying for.
Written Price, No Door Adjustment
Other roofers write a number, show up at the door, and find reasons to change it. Our price is on paper before work begins and it does not move at the door – ever. That’s The Garrison Standard in plain terms, and it applies to every estimate we write in Orange County.
What the Estimate Covers
The estimate covers materials, labor, debris removal, and any identified decking or flashing work, itemized so you can compare bids honestly. If we find hidden damage after the tear starts – wet decking, for example – we show you the damage and give you a priced change order before proceeding. You approve it in writing or we don’t do it.
Brands We Service
We’ve installed and serviced a wide range of roof systems across Orange County, and we have deep experience with specific manufacturer lines. On IKO shingle systems, we handle full replacements and understand how their hip-and-ridge profiles wear in high-sun exposure zones like North Tustin. On Atlas metal panels, we install hidden-fastener standing seam profiles and correct improper fastener patterns we find on coastal homes where salt corrosion is a factor. On Tamko architectural shingles, we’re familiar with their granule-adhesion characteristics in hot inland climates and inspect for early granule loss during maintenance visits. And on Boral stone-coated steel, we install complete systems and certify existing roofs that need warranty service.
Whether you have IKO, Atlas, Tamko, Boral, or any other make, we can help. We also work regularly with GAF, CertainTeed, and Owens Corning products. The brand matters less than the installation underneath it – but you should still know who made the materials on your roof and how to get warranty service when you need it. We’ll walk you through that during the estimate.

- Water stains on ceilings or walls. The stain means water has already penetrated the roof system and is traveling through your attic or wall cavity. By the time you see it, the leak has been active for a while. Mold and dry rot compound the repair cost the longer it waits.
- Granules in your gutters. If gutters are filling with shingle granules, particularly on the southern exposure, the shingles are shedding their UV protection and aging ahead of schedule. A few granules are normal wear. Piles of them are not. This is common on older homes in Orange and Tustin.
- Visible daylight in the attic. If you can see pinpricks of light through the roof deck from inside your attic, water has paths through the same openings. This condition exists in many homes in Santa Ana and Costa Mesa that are pushing 30 years on the original roof.
- Flashing that has separated or rusted. Flashing is the metal that seals roof transitions – chimneys, walls, pipes. When it lifts or corrodes, it stops sealing. Leaks from failed flashing are the most common roof problem we repair in Orange County, especially on coastal homes in Newport Beach and Laguna Beach where salt air accelerates corrosion.
- You can feel soft spots when walking the roof. Spongy decking means water has saturated the wood underneath the roof surface. The structural layer may be compromised. This is a safety issue for anyone walking the roof and a repair that will only grow more expensive as the rot spreads.

How Much Does Roofing Company Cost in Orange County?
A typical shingle roof replacement in Orange County runs $14,000 to $22,000 for a 1,800-square-foot home, with the final number depending on pitch, decking condition, and the shingle line you choose. Spot repairs run $350 to $1,200, tile repairs $600 to $2,400, and annual maintenance visits $195 to $450. Commercial repairs run $800 to $4,500, full commercial replacement $6.50 to $11 per square foot, and roof coating $3.50 to $7 per square foot for flat or low-slope systems. Metal installation runs $14 to $26 per square foot installed.
What affects the price: roof pitch (steeper roofs take longer and need safety systems), decking condition (if the wood underneath is rotted, that’s an additional per-sheet cost), material choice (architectural shingles cost more than three-tab, metal costs more than shingle, tile costs more than both), and access (tight side yards, multi-story homes, and HOA-restricted hours add labor). The best way to avoid overpaying is to get a line-item written estimate, not a bottom-line number. Compare the same scope across bids, not just totals.
Every free estimate from Brennan Roofing Co Orange County includes exactly that: line items for materials, labor, decking if needed, flashing, and disposal. You’ll see the real number before you decide anything. Call (559) 258-5703 to schedule yours.

Frequently Asked Questions About Roofing Company in Orange County
A roofing company is a licensed contractor that installs, replaces, repairs, and inspects roofs on homes and commercial buildings. We handle shingle, tile, metal, and flat-roof systems, including the structural decking, underlayment, flashing, and ventilation components that make a roof system work. The difference between a roofing company and a general handyman is licensure, insurance, and the warranty that stands behind the work. Call (559) 258-5703 to get a written price from a licensed Orange County roofing company.
A typical single-family shingle roof replacement takes one to two days for the tear-off and installation, with some tile or steep-slope jobs running three to four days. Weather delays are less common here than in most markets, but we still monitor conditions and won’t start a tear-off if rain is in the forecast that same day. Commercial flat roof work can run one to three weeks depending on building size and tenant requirements. We’ll give you a written timeline with your estimate, and we honor it.
Most residential roof repairs in Orange County run $350 to $1,200 for shingle work and $600 to $2,400 for tile work.
