Why Brennan Roofing Co Orange County Is Tustin’s Preferred Roofing Company
Tustin homeowners call us because we show up when we say we will and we stand behind the work in writing. As part of the Garrison Partners family, founded in 2000, Brennan Roofing Co Orange County is independently owned and operated to The Garrison Standard. That means every technician who steps onto your roof has passed a background check and arrives in uniform. You know who is on your property. No subcontractor roulette, no mystery crew.
Our phones are answered by a live person around the clock. Not a voicemail tree, not a callback queue. When a Santa Ana wind tears tiles off a Ranchland roof at 3 a.m., you get a person on the line who can dispatch a crew to Tustin. That matters here because Tustin’s inland position gets hotter, drier summers than coastal Orange County, and the wind events are real. Our Roofing Company team has seen what 90°F summers and gusting Santa Anas do to roofs across every neighborhood in this city.
Travis Oakley leads our work across Tustin. He trains every technician to follow The Garrison Code: start with a Roof Inspection in Tustin, put the price in writing before work begins, and never change the number at the door. Homeowners in Tustin who have been burned by no-show contractors or price-shifters appreciate that we operate differently. The price you approve is the price you pay.
Styles & brands we work with






Roofing Contractor in Tustin
A roofing contractor in Tustin handles full roof replacements, structural repairs, and re-decking on homes ranging from 1950s ranch houses near Old Town to steep contemporary builds in Tustin Legacy. The job typically involves tearing off the old roof, inspecting and often replacing decking, installing underlayment and drip edge, and laying new material, whether tile, shingle, metal, or flat roofing. A standard re-roof on a 1,600 – 2,200 sq ft Tustin home runs $16,000 – $34,000, with concrete tile and steep pitches pushing toward the upper end.
Get a Roofing Company in Tustin that scopes before it quotes. We walk the roof, check the decking, and write the number down before you commit to anything.
Re-Decking and Structural Work
Most 1960s concrete tile roofs in Tustin have plywood decking that is now 50 – 60 years old. Hairline spalling cracks in the tiles let moisture through, and that moisture rots the decking over time. When we strip a tile roof on Ranchland or Tustin Meadows, we usually find at least some decking that needs replacement. We include re-decking in the written quote up front, so the price does not jump mid-job.
Tile and Shingle Replacement
Asphalt shingle replacement in Tustin runs $450 – $2,800 for patching and $14,000 – $22,000 for a full replace on a typical 1990s tract home. Concrete tile replacement runs higher, usually $24,000 – $42,000, because the tiles are heavier, the underlayment has to be redone, and the decking often needs work. We quote the actual square and material, including starter strip, ridge vent, and flashing, so the number you approve is the number on the final invoice.
Commercial Roofing in Tustin
Commercial roofing in Tustin covers low-slope and flat roof systems on offices, retail buildings, warehouses, and outbuildings across the city, including shop and detached ADU roofs on acreage lots off Red Hill Avenue and Jamboree Road. These jobs involve TPO or PVC membrane work, metal roof installations, and built-up roofing repairs. A commercial flat roof repair in Tustin typically runs $900 – $5,500 depending on membrane type and penetration count, while full commercial re-roofs run $8 – $14 per square foot installed. We quote each building after an on-roof inspection.
Flat and Low-Slope Systems
Many commercial buildings in Tustin use TPO or PVC membrane systems that fail around penetrations, seams, and rooftop units. We inspect the membrane, identify the failure point, and repair it with matching material. Full replacement includes new insulation where needed, new membrane, and new flashing at every curb and penetration. The written quote covers all of it, so building owners know the real number before work starts.
Metal Roofing for Commercial Buildings
Metal roofing works well for Tustin’s summer heat because it reflects solar gain and stands up to Santa Ana wind gusts better than loose tile. We install standing seam and exposed fastener systems, with full underlayment and proper flashing at transitions. A metal roof on a Tustin commercial building or large detached garage starts around $11 per square foot. The 365-Day Done Right Promise applies to every commercial job, same as residential.
Trusted Brands We Service in Tustin
We install materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Tustin homeowners, we explain what those options actually mean for your roof era and your street. Boral tile is a common match for 1960s concrete tile homes in Tustin Meadows and Ranchland. Atlas and IKO architectural shingles are solid picks for 1990s and 2000s tract homes that came with dimensional shingles. We stock local parts in our Tustin service area so repair turnarounds are fast, and we source directly from distributor lines, not big-box leftovers.

AfterCommon Roofing Company Problems We See in Tustin Homes
- Spalling concrete tile on 1960s roofs: In Ranchland and Tustin Meadows, original tile roofs look fine from the curb but have hairline cracks through the tile body. Santa Ana winds lift those tiles and send them into yards and across streets. We catch the spalling before it becomes a mid-storm emergency.
- Rotted decking under old shake and tile: The 1950s wood shake homes near Old Town and the 1970s concrete tile tracts across the east side both hide decking rot under old roofing. If you quote a repair without checking the decking, the job goes sideways when the sheathing crumbles.
- Premature shingle granule loss: Tustin’s inland heat bakes asphalt shingles. On 1990s homes in Tustin Legacy, we regularly see granule loss and curling before year 18, well short of the 30-year warranty. The heat is the main killer, and the only fix is a full replace with a shingle rated for high UV.
- Missing starter strip and ridge vent on steep roofs: Contemporary homes with steep pitches need proper starter strip and ridge ventilation. When those get omitted to shave a quote, wind-driven rain gets under the architectural shingles and rots the fascia. We include both in every shingle quote, in writing.
Pricing for Roofing Company in Tustin, CA
Here are the ranges we quote for Tustin work, based on what we actually see in this market. Targeted repairs run $450 – $2,800. A full asphalt shingle re-roof on a standard 1990s tract home runs $14,000 – $22,000. Concrete tile re-roofs run $24,000 – $42,000 because of the weight, the underlayment, and the decking work those 1960s homes usually need. Metal roofing starts around $11 per square foot. Flat and commercial roofing runs $8 – $14 per square foot.

FAQs About Roofing Company in Tustin
A 1960s concrete tile roof in Tustin Meadows almost always needs a full tear-off, not a go-over, because the decking underneath is usually 50 – 60 years old and has rot around the valleys and drip edge. Going over old tile means the decking never gets inspected, and the added weight stresses rafters that already carry a heavy tile load. We strip to the sheathing, replace rotted decking, install new underlayment, and re-lay tile. A full tear-off and re-tile on a Tustin Meadows home runs $24,000 – $42,000. Call (559) 258-5703 for an exact written quote.
Homes near Peters Canyon catch stronger Santa Ana gusts than homes in the flat center of Tustin, and that changes how we fasten the roof. We add extra tile fasteners or upgraded shingle nailing patterns on the windward slopes, and we inspect the existing fascia and soffit to make sure they will hold the edge metal. A roof that meets minimum code in a calm area can still lose tiles on a Peters Canyon hillside. We quote the wind-specific fastening up front so the price reflects the real scope. Call (559) 258-5703 for a free estimate.
On acreage lots in Tustin, roof replacement on the main house typically falls under city jurisdiction, but detached structures, ADUs, and any grading or drainage changes can bring county review into the picture. We handle the permit paperwork and know which office to file with for which structure. The price you approve includes the permit scope, so there is no surprise at inspection time. Call (559) 258-5703 and we can walk you through what your specific lot will require.
Because Tustin’s inland summer heat cooks asphalt shingles. Temperatures above 90°F for weeks at a time accelerate granule loss and dry out the asphalt mat, so the shingle curls, cracks, and fails years before the manufacturer’s maximum rating. The rating assumes a moderate climate, not Tustin’s inland heat. When we replace those roofs, we recommend shingles rated for high UV and proper attic ventilation so the next one lasts longer. Call (559) 258-5703 for an exact quote on a Tustin Legacy re-roof.
You can often repair isolated damaged shakes on a 1950s wood shake roof near Old Town Tustin, but most of these roofs are at the end of their service life, and patching becomes a losing game. The shakes dry out, split, and the tar paper underneath breaks down. We will repair if the roof is still sound, and we will tell you plainly when replacement is the honest answer. A full replacement on an Old Town shake roof runs $18,000 – $30,000 depending on size and decking. Call (559) 258-5703 for a straight answer and a written quote.
