Fast, Reliable Roof Repair Across Santa Ana
Roof repair in Santa Ana usually falls into two buckets: wind damage from the dry fall gusts that peel shingles off older homes, or water intrusion that finally shows up after a hard winter rain. Most repairs on the city’s pre-1970 bungalows and ranch houses run between $450 and $1,800, depending on whether we’re replacing a few shingles or opening up flashing and underlayment. If you’re seeing lifted shingles, missing ridge caps, or a stain spreading across your ceiling in Santa Ana, call (855) 341-6021 and we’ll schedule an inspection first. Every recommendation we make comes with documented findings, so you know exactly what your roof needs and why.
Why Millstone Roofing Is Santa Ana’s Preferred Roof Repair Company
Our Roof Repair team has spent years working on the housing stock that defines Santa Ana: 1920s Floral Park bungalows, mid-century ranches spread through Washington Square and Wilshire Square, and post-1980s tract homes in the city’s southern ZIPs. That breadth matters because a wood-shingle roof on a 1930s French Street home fails differently than a concrete tile roof in 92705. We know what to look for before we quote anything.
Nelson Ibarra built Millstone Roofing around an inspection-first process. We don’t show up with a sales pitch and a clipboard full of upgrade options. We show up, walk the roof, document what we find, and then tell you whether a targeted repair makes sense or whether the roof has reached the end of its serviceable life. When Santa Ana homeowners call us after a wind event, they get a straight answer, not a scare tactic.
Because we work with seven major manufacturers including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, the material we recommend fits your roof and your budget. We’re not trying to move inventory. We’re trying to give your roof what it actually needs. That’s why homeowners across Santa Ana keep our number saved for the next time the winds kick up.
Styles & brands we work with






Metal Roof Repair in Santa Ana
Metal roof repair in Santa Ana typically addresses two things: failed fasteners and sealant breakdown at panel laps, or impact and wind damage along roof edges and ridge lines. Most metal roof repairs on Santa Ana homes run between $500 and $1,400. On commercial buildings with standing-seam or exposed-fastener panels, repairs usually start around $900 and can reach $3,500 for extensive panel replacement around curbs and penetrations. The semi-arid climate here bakes sealant faster than coastal areas, so we see more dried-out lap joints and gasketed washers on metal roofs in Santa Ana than homeowners expect.
Standing-Seam Panel Repairs
Standing-seam roofs fail most often at transitions: where panels meet chimneys, skylights, and equipment curbs. We remove the old sealant, inspect the clips and z-closures beneath, and replace only the compromised panels rather than covering them with goop. On Santa Ana homes with older 2×4 framing, we also check for rust at the panel-to-deck fasteners, which can silently loosen over decades of thermal cycling.
Exposed-Fastener Panel Repairs
Exposed-fastener metal roofs are common on 1960s and 1970s additions and carports throughout Santa Ana. The rubber washers under those screws wear out, and wind-driven rain finds its way in around the fastener heads. We replace fasteners with the correct size and profile, reseat panels that have crept, and reflash transitions where the original installer cut corners. On older homes in 92701 and 92703, we often find the original metal roof was laid over a rotted wood deck, which means the repair stays small only if the decking is still sound.
Commercial Roof Repair in Santa Ana
Commercial roof repair in Santa Ana spans everything from patching low-slope built-up roofs on older retail strip centers to reflashing penetrations on newer TPO and modified bitumen systems. Small commercial patches on low-slope roofs in Santa Ana generally run $700 to $2,200. Larger repairs involving deteriorated flashings, clogged drains, or split seams on aging roofs can push into the $3,000 to $8,000 range. Santa Ana’s warehouse district along the 5 and the industrial parks near the 55 corridor see their share of wind-related edge damage and ponding water after winter rains.
Low-Slope Built-Up Roof Repairs
Many commercial buildings in Santa Ana’s older corridors sit under built-up roofs installed decades ago. These roofs develop blisters, alligator cracking, and splits at parapet walls and drain sumps. We cut out the failed sections, dry the underlying insulation if needed, and tie the repair into the existing membrane so the next rain doesn’t find a seam nobody addressed. The dry season is the best time for this work; once the Santa Ana winds push moisture into open substrates, repairs get more invasive.
Flashing and Penetration Repairs
Commercial roof leaks in Santa Ana most often trace back to failed flashing, not failed membrane. HVAC curbs, exhaust fans, gas lines, and conduit penetrations all crack over time under relentless UV exposure. We reflash these areas using materials compatible with the existing roof system, then run a water test before we call the job done. It’s less expensive than replacing a roof section, and on older commercial properties it usually buys meaningful years of service.
Trusted Brands We Service in Santa Ana
We stock and install materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, which means the shingle or membrane we recommend is the one that matches your roof, not the one we happen to have a quota on. For Santa Ana homeowners, that translates to faster turnaround on repairs because we keep common colors and profiles in stock for the neighborhoods we serve. Whether you need a few Atlas architectural shingles matched to a 2000s tract home off Bristol Street, or Boral tile repairs on a 1980s two-story near the Santa Ana Country Club, we can pull the material without waiting on a slow supplier. Seven brands. One roof. The right product for the problem.

AfterCommon Roof Repair Problems We See in Santa Ana Homes
- Blown-off ridge caps on pre-1970 homes. The fall Santa Ana winds hit hardest on the low-slope bungalows and ranch houses in 92701 and 92703, peeling ridge caps and lifting field shingles. When we go up to repair those, we almost always find the underlayment beneath has baked brittle from decades of UV exposure, which means the repair has to include new underlayment, not just new shingles.
- Flashing failures around chimneys and skylights. Older Santa Ana homes often have original galvanized flashing that has rusted through or separated from the masonry. The leak doesn’t show up until a hard winter rain pushes water past the failed flashing and into the attic. Repairing the shingles without opening the flashing doesn’t fix anything; it just delays the stain.
- Low-slope built-up roof deterioration. Many 1950s and 1960s homes in Santa Ana have flat or low-slope roof sections over additions, carports, and porches. These roofs crack and alligator under the semi-arid sun, then pond water during winter rains. The repair scope depends on what’s under the membrane: if the decking has rotted, the job grows.
- Wildfire ember and code compliance concerns. Santa Ana sits in a wildfire-prone corridor, and homeowners increasingly ask whether roof repairs need to include Class A fire-rated materials or ember-resistant vents. The answer often depends on the scope of work and whether a permit is triggered. We’ll walk you through what the current California and Santa Ana code requires before we start.
Pricing for Roof Repair in Santa Ana, CA
Let’s put real numbers on it. A small shingle repair on a Santa Ana home, say replacing 10 to 20 shingles and resealing a pipe boot, runs $450 to $800. A ridge cap replacement along 30 linear feet on a bungalow in 92701 runs $600 to $1,100, including new underlayment where needed. Flashing repairs around a chimney or skylight run $700 to $1,500, depending on how much of the old flashing has to be cut out. A targeted low-slope roof patch on a built-up roof runs $800 to $1,800. If the decking underneath is compromised, the price moves up because we’re now repairing structure, not just surface. Every estimate we give in Santa Ana is a written line-item quote, and if we open something up and find a problem we couldn’t see from the roof surface, we price that change in writing before we touch it. Call (855) 341-6021 to schedule your free inspection and estimate.

FAQs About Roof Repair in Santa Ana
Those fall winds exceed 60 mph at times, but the real reason ridge caps blow off older homes in 92701 and 92703 is that the underlying felt or wood-shingle underlayment has baked brittle after 60 to 100 years of UV exposure. The caps were only as strong as what they were nailed into. When we repair those ridges, we strip the slope down to the decking where needed, lay new underlayment, and rebuild the ridge with materials rated for high-wind zones. If you’re seeing ridge caps on the ground after a Santa Ana wind event, call (855) 341-6021 for an inspection, we’ll document what failed and what needs to happen before the next one.
Yes, in many cases. The determining factor is whether the decking and framing are still sound. On a 1940s bungalow off French Street in 92701, our crew went up after a fall wind event that had peeled a run of ridge caps and lifted a dozen field shingles, and found the original wood-shingle underlayment crumbled to dust where it met the flashing at the chimney. We stripped that slope to the decking, replaced two soft fascia boards and the rusted drip edge, laid ice and water shield through the valleys and around the penetrations, and rebuilt the ridge with a new ridge vent and Class A architectural shingles nailed to the high-wind pattern. Final inspection passed with the attic breathing and the wind rating documented. If your roof has multiple slopes failing and the decking is compromised throughout, we’ll tell you that too, but we won’t recommend replacement unless the repair math doesn’t work. Call (855) 341-6021 and we’ll give you a straight answer.
It depends on the scope of work and whether a permit is triggered. Santa Ana sits in a wildfire-prone corridor, and California building codes increasingly require Class A fire-rated roofing and ember-resistant vents when the roof system is replaced or substantially repaired. A small shingle patch may not trigger those requirements. A full slope rebuild, a reroof, or any project that requires opening the roof assembly often will. During your inspection, we’ll tell you what the current code requires for your specific scope, and we’ll factor those materials into the written quote before work starts. Call (855) 341-6021 and we’ll walk you through what applies to your home.
We write allowances into the contract for the things we can’t see until the roof is opened: decking condition, rafter tail rot, existing flashing condition, and whether the sheathing meets current nailing patterns. A typical roof repair quote on a 1940s bungalow in 92701 includes a per-sheet price for decking replacement, an allowance for fascia and drip edge, and a line item for any permit-triggered code upgrades. If we find something during the repair that wasn’t in the original scope, we stop, show you photos, and get written approval before we touch it. The quote you sign is the quote you pay unless you approve a change. That’s how Nelson Ibarra runs Millstone Roofing, and it’s why Santa Ana homeowners don’t get surprise invoices from us.
Put them side by side and look for line items, not lump sums. A quote that says “repair roof, $1,200” tells you nothing about what’s actually included. Our Santa Ana quotes list the specific slopes, the linear feet of ridge, the number of shingles replaced, the underlayment type and brand, the flashing locations, and the fasteners specified. Compare our quote to the other one and ask if their number includes new underlayment, if it includes ice and water shield at valleys and penetrations, if it includes permit fees and inspection scheduling, and if it includes a written workmanship warranty. The cheaper quote usually means fewer line items, not better value. Call (855) 341-6021 and we’ll walk you through our quote line by line before you decide.
