Boral Flashing Replacement: The Dallas Owner’s Guide
We stock and install Boral-compatible flashing replacement for Dallas homeowners, with most jobs running $340-$780 installed depending on linear footage, roof pitch, and whether we’re matching existing Boral trim profiles. Same-day availability is typical for common Boral Stone Coated Steel and concrete tile flashing profiles, including eave, rake, and valley configurations. Most Dallas owners discover the problem during a hard rain: water staining the soffit, a dark line running down an interior wall, or granules collecting where the roof meets a dormer. By the time you see it inside, the flashing has been compromised for a while.
Which Boral Models This Applies To
Boral’s flashing isn’t one-size-fits-all. The Stone Coated Steel line - Roman Shake, Shingle, and Tile profiles - uses proprietary gauge and bend angles that don’t interchange with standard galvanized or aluminum stock. Concrete and clay tile systems require pan-and-cover flashing with specific leg heights to accommodate the tile profile thickness, typically 2-1/4 to 3 inches for Boral’s Barcelona and Saxony 900 lines.
To identify what you need, check the underside of any lifted tile or the edge of exposed metal for a stamped Boral part number - usually starts with BSCS for stone coated or BCT/BCL for concrete/clay. Measure the exposed face width and the vertical leg that tucks under the roofing material. If the original label is gone, we match by profile gauge and color code; Boral’s stone coated colors like Barclay, Charcoal, and Shasta White have specific Kynar-coated flashing matches that off-brand substitutes fade out of within three Dallas summers.
We carry OEM Boral flashing and select quality aftermarket equivalents where the spec matches exactly. For heritage concrete tile jobs in neighborhoods like Lakewood and Kessler Park, OEM is usually worth it - the color match and gauge consistency show. For newer stone coated installs, our aftermarket stock meets the same 26-gauge minimum and carries the same Kynar 500 finish warranty at a lower parts cost. We don’t substitute without telling you.
Signs Your Boral Flashing Replacement Is Failing
- Water stains on soffits or fascia boards. Boral eave and rake flashing directs runoff into the gutter; when the sealant bead underneath cracks or the metal pulls away from the drip edge, water runs behind the gutter and rots the fascia from the back side. In Dallas, this accelerates after summer heat cycles loosen the fasteners.
- Dark interior wall stains below roof-wall intersections. Step flashing at chimneys and sidewalls is the most common Boral failure point we see in Dallas. The stone coated profile’s raised texture creates a slightly larger gap at the wall than smooth metal, and if the counter-flashing wasn’t resealed properly during the original install, capillary action pulls water in during wind-driven rains.
- Granule or debris buildup at valley edges. Boral open valley systems use a W-profile flashing with a raised center rib. When that rib dents or the valley lining shifts, water crosses into the adjacent field instead of channeling down. Homeowners in Preston Hollow and North Dallas notice this first as a musty attic smell after spring storms.
- Visible rust or white oxidation on exposed metal. Boral’s Kynar coating is durable, but any field-cut edge or fastener penetration is bare steel. Once oxidation starts at a screw hole, it creeps under the coating. We replace the full section - spot-patching flashing is like patching a tire sidewall.
- Loose or lifted tiles along the roof edge. Boral tile clips hook over the flashing lip. If the flashing corrodes thin or the lip bends, clips lose purchase and tiles rattle or slide. This is a safety issue - a dislodged concrete tile weighs eight pounds and accelerates fast.
Replacement Cost & What’s Included
For Dallas-area Boral flashing replacement, here’s how pricing breaks down:
- Eave/rake flashing (up to 20 linear feet): $340-$520
- Valley flashing replacement: $480-$780
- Step flashing (per chimney or sidewall): $380-$640
- Counter-flashing only (reusing base): $280-$450
The range depends on roof pitch (steeper = more labor), whether we’re matching discontinued Boral color codes, and if the underlying decking needs repair where water sat. Every quote includes removal of the compromised section, decking inspection, new flashing cut and formed to spec, Boral-compatible fasteners with neoprene washers, sealant at all termination points, and reinstall of your existing roofing material. Our 90-Day Done Right Promise covers the workmanship. The price we quote is the price you pay - no surprises when we hand you the invoice.
DIY or Call Us?
There’s a safe middle ground here. You can walk the perimeter with binoculars and spot obvious rust, lifted tiles, or gutter overflow. You can check the attic during rain for active drips. What you shouldn’t do is pry up Boral tiles or attempt to bend and fasten flashing yourself. Stone coated steel edges are sharp enough to slice through work gloves, and concrete tile breaks unpredictably underfoot. More critically, improper fastening pattern or sealant placement channels water straight into the wall cavity - we’ve been called to fix DIY flashing jobs that cost three times what the original repair would have.
If you’re seeing any of the symptoms above, call us at (888) 309-8379. We’ll photo-document what we find, explain whether it’s a full replacement or a targeted repair, and get it scheduled. Most Boral flashing jobs in Dallas finish in a single visit.
FAQs
How long does Boral flashing last in Dallas weather?
Boral’s Kynar-coated flashing typically lasts 25-30 years in Dallas conditions, but the sealant joints and fastener penetrations fail sooner - usually 12-18 years, sooner if the roof faces west and takes full afternoon thermal expansion. Call (888) 309-8379 and we’ll inspect the condition of the full system, not just the metal.
Can Boral flashing be repaired instead of replaced?
Small sealant failures can be resealed if caught early, but once the metal itself is compromised - rust, thinning, bent profile - replacement is the only sound option. Patching flashing leaks almost always leaks again within two years. We don’t do patches we wouldn’t stand behind.
How long does a Boral flashing replacement take?
Most residential jobs run 3-5 hours from setup to cleanup. Valley and multi-wall jobs may stretch to a full day. We schedule with a realistic window and call when we’re en route - we will be there when we say.
Do you stock Boral flashing, or does it need to be ordered?
We stock the common Boral stone coated and concrete tile flashing profiles on our trucks. Specialty colors or discontinued lines may need a 2-3 day order from Boral’s regional warehouse in Fort Worth. We’ll know within minutes of seeing your roof. Call (888) 309-8379 to schedule - estimates are free.
