Boral Flashing Replacement in Las Vegas, NV

Boral Flashing Replacement: The Las Vegas Owner’s Guide

Boral flashing replacement in Las Vegas typically runs $340-$780 installed, depending on roof pitch and whether the surrounding tile needs resetting. We stock Boral-compatible step flashing, counterflashing, and valley flashing in common profiles, and most replacements are completed same-day. Homeowners usually notice the problem first as a water stain on a ceiling line or a musty smell in the attic after our rare but heavy desert downpours.

We’ve been replacing Boral flashing across the Las Vegas valley since 1984. The desert cycles - blistering summer surface temps above 160°F on dark tile, then sudden winter rain - separate marginal flashing jobs from proper ones within a few seasons. Ray Mulvey learned early, working roofs from Charleston Heights to Summerlin, that flashing is where a roof lives or dies. It’s not the tile people see; it’s the metal they don’t.

Which Boral Models This Applies To

Boral’s clay and concrete tile lines - specifically the Saxony, Villa, and Slate profiles most common in Las Vegas - use proprietary flashing geometries that don’t interchange with generic box-store alternatives. The critical match points are the pan width (typically 11.5 inches for standard Boral profiles), the rise-to-run ratio of the flashing leg, and the color-matched Kynar finish that Boral specifies for UV resistance in desert exposure.

Identifying your part starts with what’s visible. Boral stamps a part number on the exposed face of original counterflashing - usually a 6-digit code beginning with 3 or 4 for post-2000 installations. If the stamp’s corroded away (common after 12-15 years in Las Vegas), measure the exposed leg height and the pan width where the tile sits. We carry both OEM Boral flashing and a quality aftermarket equivalent from Custom-Bilt Metals that matches the Kynar spec and carries the same 20-year finish warranty. The aftermarket runs about 15% less, and we warranty the installation either way. For heritage Boral profiles discontinued before 2010, we fabricate matching profiles on-site from coil stock.

Signs Your Boral Flashing Replacement Is Failing

• Water staining at wall-to-roof junctions. Boral step flashing relies on a continuous metal pan tucked under each tile course. When the pan corrodes through at the bend point - accelerated by our desert UV and thermal cycling - water tracks behind the stucco weep screed and appears as a linear stain on interior walls, often misdiagnosed as a plumbing leak.
• Loose or sliding tile below chimneys or vents. The Boral flashing clip that secures tile at penetrations can fatigue after repeated expansion cycles. You’ll notice tiles that shift when walked on or a gap where the mortar bed has fallen away. Left alone, the next wind event sends tile into the yard.
• Visible rust streaks on light-colored tile. Boral’s Kynar finish is rated for 20 years, but our Las Vegas sun degrades the topcoat faster on south and west exposures. Once the galvanized substrate is exposed, rust runs stain the tile below - cosmetic at first, structural soon after.
• Musty attic odor after rain, even without visible dripping. Failed counterflashing at headwalls allows wind-driven rain to mist into the attic space. In our dry climate, homeowners often miss this for years until insulation compresses or framing shows mold.
• Mortar debris in gutters below valley lines. Boral valley flashing includes a raised center rib that sheds debris. When the rib corrodes or the valley pan separates at the seam, mortar from the tile bed washes into gutters - a tell that the valley flashing has reached end of life.

Replacement Cost & What’s Included

What drives the range: roof pitch above 6/12 adds labor time, tile that crumbles on removal requires matching stock (we carry common Boral colors), and whether the underlying felt needs patching. Our estimate includes removal of failed flashing, substrate inspection, new Boral-compatible flashing with matching fasteners, tile reset with fresh mortar where needed, and jobsite cleanup. The 90-Day Done Right Promise covers the workmanship - if water gets past our flashing, we come back and make it right, no paperwork, no arguing. A square deal: the price we quote is the price you pay.

DIY or Call Us?

There’s a short list of what a homeowner can safely check from the ground or a sturdy ladder: visible rust streaks, loose mortar, or debris patterns that point to where the problem lives. Document it with photos - we use those in our pre-call planning.

What goes wrong with DIY flashing replacement on Boral tile starts with the weight. Concrete tile runs 900 pounds per square; clay closer to 1,200. Walking it without knowing the batten spacing crushes tile and can punch through aged underlayment. The flashing itself must be bent to match the exact tile profile - too shallow and wind lifts the edge, too deep and water ponds. And then there’s the height. Most Boral flashing failures occur at valley lines, chimneys, and second-story wall junctions where a fall means a hospital bill that dwarfs the repair. We’re background-checked, uniformed, and insured for this work. Call (866) 993-9765 and we’ll give you an honest read on whether it’s a quick fix or something that needs a full look.
