Boral Flashing Replacement Nationwide

Boral Flashing Replacement: The Miami Owner’s Guide

Boral flashing replacement in Miami typically runs $350 to $900 installed, depending on the flashing type and roof configuration. We stock Boral-compatible flashing profiles on our trucks and can usually complete the swap the same day we inspect it. Most Miami homeowners discover failed flashing after a storm, when they notice a water stain creeping across the ceiling under a wall or a musty smell that won’t go away.

Flashing is the metal or composite material that bridges the gap where your tile roof meets a wall, chimney, skylight, or valley. When it fails, water finds the gap. And in Miami’s afternoon downpours, water finds gaps fast. If you’re seeing the signs below, the flashing is almost always the culprit, not the tile itself.

Tilehurst Roofing Miami is an independent service provider, not affiliated with Boral. That independence matters: we match the right flashing to your Boral profile because we install what fits your roof, not what a single manufacturer ships us.

Which Boral Models This Applies To

Boral’s tile profiles each have a specific flashing geometry, and that’s where most generic repairs go wrong. The main Boral product lines you’ll see on Miami homes are the Boral Concrete Roof Tile profiles (including the classic barrel and flat S-tile shapes), Boral Slate, and Boral CedarLite. Each one sits differently against the wall, which means the flashing has to be formed to match the tile’s rise and profile depth.

The compatibility gotcha most owners miss: Boral’s barrel tile profile is taller than most competing barrels, so a stock flashing piece cut for a flatter tile will leave a gap at the step line. That gap is exactly where Miami’s wind-driven rain gets pushed up and under the flashing. A correct replacement starts with measuring the tile’s profile rise, not just the length of the wall run. We measure both, and we match the flashing to the tile, not the other way around.

OEM Boral flashing (when still available for your profile) is the most precise match, but quality aftermarket flashing in 26-gauge aluminum or 24-gauge galvanized steel often equals or outperforms older OEM pieces, especially after twenty-plus Miami summers. We’ll tell you honestly which direction makes sense for your roof and your budget, with a written price before any work starts.

Signs Your Boral Flashing Replacement Is Failing

• Water stain below a wall or chimney on the ceiling. This is the classic flashing leak signature: water entering where the roof plane meets a vertical surface, then traveling down a rafter before dripping. The tile above often looks fine.
• Loose, lifted, or cracked flashing visible from the ground. Walk around your house and look at the metal where the roof meets the walls. If it’s peeling, rusting, or pulling away from the tile, water has already started working its way in.
• Persistent musty smell in one room after rain. That’s trapped moisture in the attic or wall cavity, and it often indicates a slow flashing leak that never dries out in Miami’s humidity.
• Dark staining at the top edge of exterior walls near the roofline. Water running down the inside of the wall from failed flashing will eventually show through stucco as a shadow of mold or mineral deposit.
• Flashing that has been patched with roof cement or caulk. If a previous contractor smeared sealant over a flashing joint instead of replacing the piece, it’s a temporary fix that Miami sun and rain will break down within a season or two. We see this constantly.

Replacement Cost & What’s Included

Here’s what Boral flashing replacement runs in the Miami market:

• Step flashing replacement (small wall run, up to 15 linear feet): $350 – $550
• Wall flashing replacement (full wall intersection, 15 – 30 linear feet): $500 – $750
• Chimney flashing replacement (including reglet cut and counterflashing): $550 – $900
• Valley flashing replacement on Boral barrel tile: $450 – $700

What drives the range is access (how steep the roof is, whether scaffolding is needed), how many tiles have to be lifted to seat the new flashing properly, and the flashing material itself. Every price we give includes the flashing material, the labor, the tile reset, and a written guarantee on the repair. You’ll have the written price in hand before we touch your roof – that’s how the Kingswell Way works, and Greg Holloway wouldn’t have it any other way.

DIY or Call Us?

Here’s the honest split. You can safely check your flashing from the ground: look for lifted or missing pieces, rust streaks, visible gaps where metal meets wall. You can also note where ceiling stains line up with roof penetrations inside. Those observations help us quote the job accurately over the phone.

What gets homeowners in trouble is climbing onto a tile roof to “just take a look.” Boral tile is heavy, often slick with Miami humidity and rain, and walking it incorrectly cracks tiles that then need replacing too. Working flashing at the roofline means being on a ladder at roof height while pulling metal and resetting tile – that’s a two-person job with the right tools and fall protection. We’ve repaired enough homeowner attempts to know it costs more to fix than the original flashing replacement would have.
