Boral Flashing Replacement: The Austin Owner’s Guide
Boral flashing replacement in Austin typically runs $380 to $850 installed for most residential roof-to-wall and chimney transitions, depending on how much of the surrounding tile or stone has to come up to do it right. We stock Boral-compatible flashing profiles on our trucks, and most single-flashing swaps happen the same day we show up. The way most Austin homeowners discover the problem is a water stain on an interior ceiling after a spring storm, or a visible gap where the flashing has pulled away from the wall.
Flashing is the metal or synthetic material that sits at every seam where your Boral roof meets something else. A chimney, a dormer wall, a skylight curb, a pipe boot. When it fails, water doesn’t announce itself. It works its way under the tile, follows the underlayment, and puddles somewhere you can’t see until the drywall gets soft. Greg Holloway has pulled flashing off Boral roofs in Travis Heights that looked fine from the ground and were nothing but rust flakes underneath.
Which Boral Models This Applies To
If you have Boral roofing, you have either concrete tile or steel. Each uses different flashing approaches, and the compatibility question depends on which one is up there. Boral concrete and clay tile profiles (think flat, low-profile, and barrel shapes) require step flashing that matches the tile’s rise. Boral steel, including the stone-coated and corrugated profiles, uses a different flashing geometry altogether.
How to identify what you need: look for the tile’s edge profile and measure the vertical rise from the decking to the top of the tile. That rise determines the step height of the flashing. An off-the-shelf hardware store flashing cut for a 3-tab asphalt shingle will not follow a Boral barrel tile’s curve. That’s the most common compatibility gotcha we see, and it’s the reason a previous “repair” often leaks within a year.
On the OEM versus aftermarket question: Boral doesn’t manufacture flashing itself. What home centers label as “Boral flashing” is usually a generic profile cut to fit common Boral tile dimensions. We use either the profile-matched metal specified for your tile or a heavier-gauge aftermarket equivalent that’s cut and bent on site to your roof’s actual measurements. The better aftermarket flashing, honestly, often outlasts whatever was there originally because we step up to 26-gauge galvanized or aluminum where the original was thinner.
Tilehurst Roofing Austin is an independent roofing contractor, not affiliated with or endorsed by Boral. We install Boral-compatible flashing replacement parts and have working knowledge of the brand’s profiles.

Signs Your Boral Flashing Replacement Is Failing
- Interior water stains near walls, chimneys, or skylights. Water runs down the inside of the flashing gap and onto the ceiling or upper wall, which is why the stain often appears a few feet away from where the problem actually is.
- Visible rust or flaking metal at the flashing joints. Austin’s humidity plus decades of sun and the occasional freeze cycle will crack and rust the thinner original flashing, especially at the bottom edge where water sits longest.
- Flashing pulling away from the wall or chimney mortar. The sealant between flashing and masonry fails first, because freeze-thaw cycles in central Texas pull it apart faster than people expect. Once it gaps, wind-driven rain gets straight in.
- Crumbling or missing mortar around chimney flashing. The mortar joint is the first line of defense above the flashing. When it erodes, water tracks down the brick and overloads the flashing underneath.
- Loose or cracked tile directly above a flashing run. If a Boral tile above the flashing has shifted, the overlap that kept water on the flashing is gone. You may not notice the missing tile from the ground, but your ceiling will.
Replacement Cost & What’s Included
Most Boral flashing replacements in the Austin area land between $380 and $850 per flashing run. A simple pipe boot or skylight curb bend sits at the low end. A full chimney with counter-flashing that has to be cut into the mortar sits at the top. If we need to lift and reset tile around the flashing to get proper overlap, that adds $150 to $300 per section, and we’ll tell you that before work begins.
| Scope | Typical Austin Installed Range |
|---|---|
| Pipe boot or small vent flashing | $180 – $300 |
| Skylight curb flashing | $350 – $550 |
| Wall-to-roof step flashing (per 10 – 12 ft) | $400 – $700 |
| Chimney flashing with counter-flashing | $650 – $1,100 |

Flashing replacement on a Boral roof is one of those jobs that looks simpler than it is. You can safely inspect from the ground: look for lifted flashing, visible rust, or missing tile. You can also check your attic for water marks after a rain. What you shouldn’t do is walk a tile roof without proper harnesses, or attempt to lift Boral tiles to access the flashing underneath. Tile is brittle, the underlayment is fragile, and one cracked tile in the wrong spot turns a $400 flashing fix into a $2,000 tile replacement job.
The other honest issue is the geometry. If your flashing has to be custom-bent to match the tile profile, or counter-flashing has to be cut into mortar, that’s not a caulk gun and a Saturday. That’s a brake, a grinder, and someone on a ladder who’s done it before. If your flashing is visibly failing, call (254) 540-7345. We’ll look at it, tell you the price before we touch the roof, and have it done while the weather’s still dry.
FAQs
Original flashing on Boral tile roofs in the Austin climate typically lasts 15 to 25 years before it needs replacement, though freeze-thaw cycles and heavy tree cover can cut that to under 12. Stone-coated steel Boral roofing uses a longer-lived flashing system that can push 30 years. Call (254) 540-7345 and we’ll give you an honest assessment of what’s left on your flashing.
In about 30% of cases, flashing can be resealed and re-fastened as a temporary fix. If the metal is rusted through, torn, or pulling away from the roof deck, patching buys you months, not years. We’ll show you photos and quote both options if a patch is genuinely viable, then let you decide. Most homeowners in that situation choose replacement because the price difference isn’t worth another leak.
Most single flashing replacements take our crew 2 to 4 hours on site. A full chimney with counter-flashing can run 5 to 6 hours because the mortar has to cure properly. We don’t rush cure times. If the weather cooperates, it’s a same-afternoon job in most cases.
Yes. Our trucks carry Boral-compatible step flashing profiles for the common concrete tile shapes, plus the 26-gauge galvanized and aluminum stock we need to custom-bend for steel Boral profiles. If we have to match a specialized profile we don’t have on the truck, it’s a one-day order from our local metal supplier, and that’s reflected in the written quote before work starts.
