Boral Flashing Replacement Nationwide

Boral Flashing Replacement: The Los Angeles Owner’s Guide

We stock and install Boral-compatible flashing replacement throughout Los Angeles, with most jobs running $285 to $640 installed depending on flashing type, roofline configuration, and accessibility. Most flashing failures show up first as a ceiling stain or paint bubbling on an interior wall, and the typical homeowner discovers the problem during the first rain after the sealant finally gives out. If you’re seeing water where it shouldn’t be, the flashing is usually the culprit, not the tile itself.

Here’s what matters: Boral roof systems rely on the flashing detail as much as the tile. The tile sheds water, but the flashing is what keeps water moving past the corners, valleys, chimneys, and wall intersections. When a previous roofer used generic hardware-store flashing instead of a properly profiled piece, the roof leaks within a season or two. That’s the repair we see most in Los Angeles, and it’s also the easiest to correct when you know what the original spec called for.

Key Takeaways:

• Boral flashing replacement in Los Angeles typically costs $285 to $640 installed
• We stock Boral-profile flashing on the truck for common tile profiles and configurations
• Written guarantee on every flashing repair, backed by the 365-Day Done Right Promise
• Free second visit if the repair fails inside the guarantee period

Which Boral Models This Applies To

Boral’s concrete and clay tile lines share a common flashing philosophy but not universal part numbers. The profile shape of the tile determines which flashing step profile you need. A Boral flat profile tile, common on mid-century homes in the San Fernando Valley, takes a different flashing height than the high-barrel “S” profile you see throughout Pasadena and the foothill communities. That’s the compatibility gotcha most homeowners never hear about until the repair leaks again.

When we arrive for a flashing estimate, we identify the Boral tile profile first, then match the flashing to the profile’s rise and pan depth. OEM Boral flashing is well-made, and when the original installation is intact, we prefer to keep the system consistent. But aftermarket flashing from a handful of Southern California sheet-metal shops is genuinely equivalent for many applications, and it’s often the faster option because we can have it cut and bent to match odd roof-to-wall intersections that a stock OEM piece won’t cover. The right choice depends on the roof detail, not on what’s easier to order.

We are an independent Los Angeles roofing company, not affiliated with Boral, but we install and repair these roofs because they’re a major percentage of what’s on homes here. Tilehurst is a Kingswell family roofing company, and our materials program carries the full range: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. When you need flashing matched to a Boral roof, we’re already set up to source it correctly.

Signs Your Boral Flashing Replacement Is Failing

• Staining on ceilings or upper wall corners after rain. This is the classic first sign. Water enters at a compromised flashing point and travels along a rafter or truss before showing up inside, often several feet from the actual leak.
• Loose, lifted, or visibly cracked flashing at roof-to-wall intersections. In Los Angeles, the repeated heat-and-cool cycle works metal flashing back and forth until fasteners loosen and sealant separates. If you can see daylight behind the flashing counterflashing, it’s already failing.
• Rust streaks down the wall or roof surface. Galvanized flashing eventually sacrifices its coating in our coastal and smog-heavy air. Once the zinc layer is gone, the steel beneath rusts through faster than most homeowners think possible.
• Granule loss or cracked adhesive around chimney flashing. Chimney flashing takes more weather than any other flashing point on the roof. The expansion and contraction at the transition from masonry to roofing material breaks sealant bonds season after season.
• Water in the attic after a wind-driven rain, even though the roof doesn’t visibly leak. Wind pushes water upward and sideways along roof planes. Flashing that holds fine in a vertical downpour will fail when rain comes in at an angle, which is exactly what happens during Santa Ana-adjacent storm patterns.

Replacement Cost & What’s Included

In Los Angeles, Boral flashing replacement runs $285 to $640 installed for most single-point repairs. A straightforward pipe boot or small step flashing replacement sits at the lower end. A full chimney flashing rebuild with new counterflashing, reglet cut into the mortar, and sealant work lands in the $500 to $640 range. Complex valley re-flashing or full roof-to-wall runs on larger homes can exceed that, and we’ll never surprise you with that number after the fact.

Every flashing quote from Tilehurst includes parts, labor, sealant, fastener replacement, and cleanup. You get a written price before any work starts. The written guarantee on the repair is delivered before our crew leaves, not mailed later. And because this is a Kingswell family company, the 365-Day Done Right Promise applies: if the flashing repair fails inside a year, we return and make it right at no charge. That’s the entire deal, in writing, before the first tile moves.

DIY or Call Us?

You can safely do the detective work. Get a ladder, look at the flashing from the ground first, then from the roofline if you’re comfortable with heights. Check for lifted edges, missing fasteners, cracked sealant, and rust. A caulk tube of roofing sealant applied to a minor hairline crack might buy you a season. But on a tile roof, the risk of DIY flashing work isn’t just a bad seal. It’s the tile you crack while working around the flashing, or the nail you drive through the underlayment trying to secure a piece that won’t stay down anyway.

Working at height on a pitched tile roof is realistically a two-person job with proper fall protection. And here’s the thing about Boral tile specifically: if you snap a tile while accessing the flashing, you’re replacing a tile too, and Boral tile isn’t a $5 hardware store item. A failed flashing repair that leaks again inside a month costs more than the original repair. That’s the math. Call (945) 303-9821 and let’s get the flashing matched to the profile, sealed correctly, and guaranteed in writing.
