Boral Flashing Replacement Nationwide

Boral Flashing Replacement: The Houston Owner’s Guide

Boral flashing replacement in Houston typically runs $350 – $900 installed, depending on linear footage, roof pitch, and whether we’re pulling up shingles or working around tile. We stock Boral-compatible flashing on our trucks and can usually complete the swap the same day we diagnose it. Most Houston homeowners discover failed flashing the hard way: a water stain on the ceiling, a musty smell in the attic, or damp drywall along an exterior wall after a hard Gulf Coast rain. The flashing is the metal or composite material that bridges the gap where your roof meets a wall, chimney, skylight, or valley. When it fails, water gets exactly where it shouldn’t.

Which Boral Models This Applies To

Boral manufactures concrete and composite roof tile systems, and the flashing requirements vary by profile. The most common Boral profiles we replace flashing on across Houston are the flat, low-profile tiles used on mid-century ranch homes in Meyerland and Oak Forest, plus the heavier barrel and S-tile profiles common in master-planned communities like Katy, Cypress, and Sugar Land. If you’re not sure which Boral profile you have, check the underside of a loose tile or look in your original build documents. Boral stamps profile codes on tile backs, but on a 20-year-old Houston roof, those stamps are often faded or covered in dust. We can identify the profile by the tile’s shape and dimensions when we’re on site.

Here’s the compatibility gotcha most Houston homeowners don’t know: Boral’s tile profiles require specific flashing heights and kick-out details that differ from standard composition shingle flashing. A generic step flashing from a big-box store will not seal correctly against a Boral barrel tile. The flashing has to be cut and bent to match the tile’s rise and contour, or water will track sideways along the underlayment. When it comes to OEM versus aftermarket, Boral-branded flashing is manufactured to spec, but quality aftermarket coil stock in matching gauge and finish performs just as well when fabricated correctly. We use both depending on what the roof needs. The critical factor is the installation detail, not just the brand stamped on the metal.

Signs Your Boral Flashing Replacement Is Failing

• Water stains on ceilings or walls near chimneys, dormers, or roof-to-wall junctions. This is the most common call we get. The stain appears several feet away from the actual leak because water runs along the roof deck before it drips, and by the time you see it, the flashing has likely been compromised for months.
• Loose, lifted, or missing flashing sections visible from the ground. Houston’s wind events, from afternoon thunderstorms to hurricane remnants, work metal flashing loose over time. If you can see daylight between the flashing and the wall or tile, water can get in.
• Rust, corrosion, or pitting on exposed flashing. Houston’s humidity and salt air near Galveston Bay accelerate corrosion. Once rust eats through the metal, the flashing is no longer watertight, even if it still looks like it’s in place.
• Granules or tile fragments collecting in gutters near flashing points. Failed flashing often allows water to undermine the tile or underlayment around the penetration, which breaks the bond and sends material into the gutter. It’s a secondary sign that the flashing has been leaking for a while.
• Mold or mildew smell in the attic after rain. By the time you smell it, moisture has been coming in long enough to colonize. Failed flashing is one of the leading causes of attic mold in Houston homes, and the fix is the flashing first, then the cleanup.

Replacement Cost & What’s Included

In Houston, expect to pay $350 – $900 for most Boral flashing replacement jobs. A short run of step flashing along a chimney or a small wall junction runs on the lower end. A full valley replacement with new underlayment, or flashing around multiple penetrations, pushes toward the higher end.

What drives the price: roof pitch and accessibility, whether we’re pulling and re-setting Boral tile or working with a composition shingle transition, and how much of the underlayment has to be cut back to reach solid decking. We write the price before any work starts. The number on that paper is the number you pay. That’s the Garrison Standard.

Every flashing replacement includes new flashing fabricated or matched to your Boral profile, the necessary fasteners and sealant, underlayment repair as needed, and re-setting any tile we disturbed. The work is guaranteed in writing for one full year under the 365-Day Done Right Promise. If it fails within that year, we come back and fix it at no charge.

DIY or Call Us?

Flashing replacement on a Boral tile roof is not a ladder-and-caulk job. Concrete tile is brittle, and walking it wrong cracks tiles faster than you can replace them. If your flashing is leaking, you can safely do a few things from the ground: check for visible rust or separation, look for lifted flashing after storms, and note where water stains appear inside. What you shouldn’t do is climb onto a tile roof without knowing how to distribute your weight, because a cracked tile becomes a second leak you’ll be chasing a month later.

Also, the adhesion between flashing and Boral tile depends on correct lap direction, proper sealant, and the right gauge of metal. Get any of those wrong and the leak comes back, or worse, it moves somewhere you won’t see until the decking is rotted. If you suspect your flashing is failing, call us at (940) 461-8481. We’ll send a background-checked, uniformed technician to diagnose it, give you a written price, and if the fix makes sense, we handle the whole thing while you keep both feet on the ground.
