Boral Roof Repair in San Antonio: What to Know First
Boral roof repair in San Antonio typically runs $350 – $900 for common fixes like shingle replacement, flashing repair, and leak sealing, with most jobs completed same-day once parts are on hand. We’re an independent Boral service provider, not a factory-authorized dealer, which means we make repair decisions based on what actually works on a Texas roof, not what a warranty department prefers. This page is for Boral homeowners in San Antonio who want to know exactly what’s wrong, what it costs, and who’s coming to the door before they commit.
If you want a straight answer about your Boral roof, call (254) 276-4369. A live person answers, and we’ll give you a written price before any work starts.
How Boral Products Fail and How We Fix Them
Boral makes a few roofing products that show up regularly on San Antonio homes, and each one fails in its own particular way. Here’s what we see on actual job sites, not in a brochure:
- Boral Concrete Roof Tile (the Mission/Spanish profiles common in Alamo Heights and Terrell Hills): The tile itself rarely fails. What fails underneath it is the underlayment, usually after 15 – 20 years of San Antonio heat cycling. You’ll see water staining on ceiling corners or damp spots in the attic that seem to move around. The fix is lifting tiles in the affected area, replacing the underlayment, and resetting the same tiles. A patch job over bad underlayment just sends the water somewhere else.
- Boral Cedar-grain composite shingles: These are dimensionally stable, but we see edge cupping on south-facing slopes after a decade of direct sun. Cupped edges catch wind and start lifting at the corners, which lets rain sneak under the shingle above. The repair is selective replacement with color-matched stock, but we always check the decking underneath for sun-driven drying and cracking before we nail anything down.
- Valley metal failures: Boral tile and composite roofs both use metal valleys, and San Antonio’s summer-to-winter expansion cycle works those seams hard. We regularly replace valley metal on Boral roofs where the metal has fatigued and split at the bend, especially on steeper slopes in the Hill Country-facing neighborhoods. The telltale is rust streaks or a leak that shows up only in heavy rain.
- Flashing failures at chimneys and skylights: This isn’t unique to Boral, but it’s the most common repair on Boral tile roofs because the flashing has to be shaped around the tile profile. When a roofer bends standard step flashing instead of profiling it, water pools behind the tile and finds a seam. We profile flashing to match the tile, not the cheap way. Grant Whitlock has spent years on these exact details, particularly on older Alamo Heights homes where the flashing is original and the masonry has shifted.
- Vent boot and pipe collar deterioration: On both Boral tile and composite applications, the rubber collars around plumbing vents crack from UV exposure in about 8 – 12 years. The leak is small but persistent, and it drips onto insulation so it’s hard to trace until the stain bleeds through. We replace the boot and reseal the penetration, then check the surrounding tile or shingles for any water damage that needs attention while we’re up there.

Our Boral Roof Repair Process
Here’s what happens when you call us for Boral work. No surprises, no mystery crew:
- 1
You call (254) 276-4369. A real person answers, day or night. We ask about the symptom, not your credit card.
- 2
We schedule a visit and send you the tech’s name and photo before they arrive. You’ll know exactly who’s at the door. They’ll be in a marked uniform with a photo ID badge.
- 3
The tech does a full inspection of the affected area, plus a look at the surrounding sections. We won’t quote a patch if the problem starts three feet away.
- 4
You get a written price before anything is touched. We decide together on OEM versus quality aftermarket parts, and we explain the trade-off honestly. For Boral tile, OEM is usually the only way to match profile and color. For underlayment and flashing, we spec better-than-original materials when it makes sense.
- 5
We do the repair. Careful tile handling, proper flashing profiling, thorough cleanup. No nails left on the grass, no tile chips in the gutter.
- 6
We test the repair and document it. You get a written guarantee on every repair, good for 365 days. If the fix fails within that year, we come back free.

Why San Antonio Homeowners Call Mercer Roofing Co San Antonio for Boral Work
We know what a Boral roof needs in this climate because we’ve spent real time on them across San Antonio, from Alamo Heights to Stone Oak. But the reason people pick up the phone is simpler than that. Every technician we send is background-checked and identity-verified under the Threshold Verified standard, and their name and photo come to you before they arrive. They badge in at the door with a photo ID. That’s not a gimmick, it’s protection. You’re letting someone onto your roof and around your family, and you should know exactly who that person is.
We’re founded in 2000 and part of the Threshold Group family, and every Boral repair gets a written price up front, a 365-day Done Right Promise, and our multi-brand experience with GAF, Owens Corning, and CertainTeed as backup when a full replacement is the smarter call. A roof shouldn’t be something you worry about, that’s our job.
Boral Roof Repair FAQs
No. As an independent Boral service provider, our repairs are performed in accordance with standard roofing practice and won’t void an active Boral product warranty. What will void a warranty is leaving a leak unresolved and letting the underlying structure fail. If you’re concerned, we can document the repair thoroughly so you have a record if a future claim comes up.
Most Boral tile repairs are completed in a single day, assuming the needed tile profile is available locally. If we have to order a specific color or profile, that adds a few days to a week. We’ll tell you the timeline before we touch the roof, and the written price includes that schedule. Call (254) 276-4369 and we’ll give you a realistic time frame for your specific roof.
If the tile itself is intact and the issue is flashing, underlayment, or a localized leak, repair almost always makes financial sense. Boral concrete tile is designed to last decades; the components around it fail first. Replacement becomes the right call when the decking is compromised over a large area or when 30% or more of the tile field is cracked or missing. We’ll show you what we see during the estimate and you make the call with real information, not a sales pitch.
For tile, yes. Matching Boral profile and color with aftermarket tile creates a patchwork look and often leads to improper underlying fit. For underlayment, flashing, and fasteners, we spec materials that exceed the original installation standard where it improves longevity. We’ll explain which parts matter and which ones don’t on your specific roof.
We do everything we can to get a technician out quickly, but good Boral work can’t be rushed on the inspection side. We need daylight and a dry roof to give you a real diagnosis. What we won’t do is throw a tarp over the problem and call it done. Call (254) 276-4369 and we’ll be straight with you about timing. Estimates are free.
