Boral Flashing Replacement: The Fort Worth Owner’s Guide
Boral flashing replacement in Fort Worth typically runs $220 to $480 installed per area, depending on roof pitch, accessibility, and whether the flashing was integrated into a Boral product like a chimney chase, skylight curb, or sidewall transition. We stock Boral-compatible flashing on our trucks and can usually complete a standard flashing swap in a single visit. Most Fort Worth homeowners discover the problem after a spring storm: a water stain near the chimney, a damp spot on a ceiling corner, or a drip during the first heavy rain in May.

Which Boral Models This Applies To
Boral flashing integrates with their broader exterior line, including the TrueExterior siding and trim system, the Inspire stone veneer panels, and the Boral roof tile profiles commonly seen on higher-end Fort Worth homes in neighborhoods like Tanglewood, Mira Vista, and along the Trinity Trails corridors. The flashing itself is the metal or polymer barrier where a Boral surface meets a dissimilar material: chimney to tile, wall to roof deck, skylight to shake. We are an independent service provider, not affiliated with Boral, but we work with both OEM Boral flashing and high-grade aftermarket equivalents matched to the same gauge, profile, and exposure dimensions.
One compatibility gotcha we see on older Fort Worth homes: the original Boral flashing may have been site-bent by the original installer, so the replacement needs to be measured against the actual opening, not the catalog spec. The difference between a 4-inch and 5-inch kick-out on a Boral tile transition matters, especially on the steeper 8/12 and 10/12 pitches common in the Fairmount Historic District, where Erik Lindgren has spent more than a few afternoons reworking flashing that was never lapped right in the first place.

Signs Your Boral Flashing Replacement Is Failing
- Water staining at a wall-to-roof intersection. This is the most common first signal. When flashing loses its seal or was installed without proper counterflashing, wind-driven rain from a Fort Worth thunderstorm gets pushed up under the siding or tile.
- Rust or white oxidation on exposed metal. Fort Worth’s freeze-thaw cycles and summer humidity work on flashing differently than drier climates. Once the protective coating goes, the metal thins and pinholes start leaking within two to three seasons.
- Cracked or lifting sealant around pipes and chimneys. The caulk bond on flashing penetrations rarely survives a full Texas hail season intact. Once the sealant pulls away, water rides the flashing plane straight into the roof deck.
- Damp drywall or peeling paint near the ceiling. By the time you see a ceiling stain, the flashing has likely been compromised for months. Roof decking below a failed flashing section starts to rot quietly, and the repair scope grows the longer it goes.
- Granule loss or tile shifting around the flashing area. If the Boral tiles or shingles adjacent to flashing start moving, the mechanical attachment has loosened. That movement opens the lap joints and lets water under the metal in a way caulk can’t fix.

AfterReplacement Cost & What’s Included
Most Boral flashing replacement jobs in Fort Worth fall between $220 and $480 for a single penetration or transition, with wider dormer or chimney flashing runs landing closer to $650. The cost moves based on how many pieces need replacing, whether the roof pitch requires additional safety setup, and whether the surrounding Boral material has to be temporarily lifted and re-set. You’ll see your exact number in writing before we touch a shingle – that’s a company rule, not a courtesy.
Every flashing replacement includes the replacement flashing itself, removal of the failed section, inspection of the surrounding decking, re-integration with the existing underlayment, and fastening that holds through Fort Worth’s wind patterns. We also cover the work under our 365-Day Done Right Promise: if the flashing isn’t right, we make it right.
DIY or Call Us?
You can absolutely do the visual check: look for lifted edges, cracked sealant, or daylight coming through at the flashing seams from inside the attic. That tells you something’s wrong without putting yourself at risk. What we’d caution against is the actual replacement. Flashing work means working at the roof edge or on a pitched surface, often with roofing materials already loose from storm damage. That’s where homeowners get hurt. We use safety harnesses, roof jacks, and a second person on every flashing job, and we lay down protection inside your home the same way – shoe covers at the door, drop cloths through the hallway, all debris cleared and photographed before we leave. If the dog needs to stay inside, we’ll coordinate the door schedule with you. Call (682) 990-0964 and we’ll take it from there.
FAQs
Boral flashing generally lasts 15 to 25 years in the Fort Worth climate, but the sealant bonds around it often fail at the 8-to-12-year mark. The metal itself is fine; the caulk is the weak link. That’s why a visual inspection every spring before hail season catches problems early. Call (682) 990-0964 for an exact quote – estimates are free.
Yes, in a limited sense. If the flashing is intact and only the sealant has cracked, a professional can re-seal the penetration and buy you a few more seasons. But if the metal has pinholes, rust, or visible separation at the lap joints, patch sealant is a temporary bandage. We’ll tell you which situation you have before doing any work, and the quote reflects that honesty.
A standard flashing replacement usually takes two to four hours on site, including set-up, removal, installation, and clean-up. Larger jobs with multiple penetrations or chimney re-flashing can run a full day. You’ll know the timeline in writing before we start.
We stock common Boral-compatible flashing profiles and gauges on our trucks, along with equivalent parts for GAF, Owens Corning, and CertainTeed systems. If your job calls for a specific OEM Boral part that isn’t on the truck, we source it directly and schedule the replacement around the delivery, usually within the same week.
