Boral Flashing Replacement Nationwide

Boral Flashing Replacement: The Riverside Owner’s Guide

Boral flashing replacement in Riverside typically runs $380 to $740 installed, depending on the linear footage, roof pitch, and whether the flashing is exposed or buried under tile. We stock Boral-compatible flashing profiles on our trucks and can usually complete the swap the same day we assess it. Most homeowners discover the problem the way you probably did: a water stain on the ceiling after the first real rain, or a piece of bent metal visible from the ground after a Santa Ana wind event.

Flashing is the metal that keeps water from getting in where the roof meets a wall, chimney, skylight, or valley. When it fails, water gets behind the Boral tile and into the decking. By the time you see the stain inside, the flashing has been failing for weeks or months. Travis Oakley has pulled enough corroded flashing off Riverside homes to know that what looks like a small exterior problem is usually worse underneath.

Which Boral Models This Applies To

This covers flashing replacement for Boral concrete and clay roof tile systems, including the Boral Cedarlite, Boral Villa, Boral Capistrano, and Boral Saxony profiles common across Riverside County. The flashing itself is generally not a Boral-manufactured part on older installs; it was cut and bent on site by the original roofing crew. What matters for compatibility is the tile profile thickness and the way the original flashing was integrated with the Boral underlayment.

Here’s the gotcha most homeowners don’t know: the flashing geometry depends on the tile’s installed height above the deck. Boral clay tile sits higher off the deck than Boral’s thinner concrete profiles, which changes the step flashing dimensions. A flashing cut for concrete tile will not seal correctly under clay tile, and we see that mistake regularly on Riverside homes where a previous repair used the wrong profile. We measure the tile rise before cutting any replacement, and we match Boral’s underlayment seam requirements so the repair doesn’t create a new leak path.

On the OEM-versus-aftermarket question: flashing is almost always fabricated from coil stock, and there is no meaningful “OEM” flashing for Boral tile systems. What matters is the metal gauge and finish. For Riverside’s sun exposure and the tannins in some Boral concrete tile, we recommend 26-gauge minimum with a galvanized or Galvalume coating, or better, pre-finished steel or copper at chimney and wall intersections where replacement is hardest. We carry 26-gauge Galvalume and pre-finished steel on the truck; copper is available on order for specific Boral installations where the homeowner wants it to outlast everything else on the roof.

Brennan Roofing Co Riverside is an independent roofing contractor and is not affiliated with Boral Steel or Boral Roofing. We install Boral products and Boral-compatible flashing, but we are not a Boral-owned or Boral-authorized service center.

Signs Your Boral Flashing Replacement Is Failing

• Ceiling or wall stains near a chimney, wall, or skylight. Water is getting past the flashing and traveling along the decking before it drips where you see it. The actual failure point is usually uphill of the stain.
• Visible rust or corrosion on exposed flashing. Riverside’s dry climate slows rust compared to the coast, but sprinkler overspray and morning condensation still eat through thinner metal. Once pinholes form, water gets in.
• Lifted or bent flashing after a Santa Ana wind event. High wind gets under the exposed edge and peels it up. Once flashing is lifted, even slightly, water channels behind it.
• Cracked or missing sealant where flashing meets vertical walls. The original installers used a sealant bead to close the gap but they all degrade under Inland Empire UV. When the sealant is cracked, water follows the gap down to the deck.
• Granular residue or rust stains running down the tile below the flashing. That means the metal is actively oxidizing and losing material. It is no longer a barrier; it is a sieve.

Replacement Cost & What’s Included

In Riverside, expect to pay between $380 and $740 for a typical Boral flashing replacement on a single wall, chimney, or dormer. The spread comes down to three things: how many linear feet of flashing need replacing, whether the existing flashing is buried under Boral tile so tile must be lifted and reset, and how steep the roof is. Single-story walkable roofs land on the low end. Chimney flashing with a cricket, or flashing on a steep second-story elevation, lands higher.

Here’s what the price covers, in writing, before any work starts:

• Removal and disposal of the failed flashing.
• New flashing fabrication to match Boral tile profile and rise.
• Fasteners and sealant rated for metal-to-tile application.
• Tile lifting and resetting where flashing is buried.
• Cleanup and haul-off of all material.
• The 365-Day Done Right Promise: if the flashing repair fails within one year, we come back and fix it at no charge. In writing.

We do not change the price at the door. The number goes on paper before any work starts, and it does not move unless you add scope. That’s The Garrison Code, and it is the same on every Boral flashing job in Riverside.

DIY or Call Us?

You can do two things safely before you call us. First, look at the flashing from the ground with binoculars after a rain. You’re looking for standing water, lifted edges, or visible rust. Second, check the ceiling or wall outlet nearest the suspected area for moisture or staining, and mark it with tape so you can tell a roofer exactly where you saw it. That saves diagnosis time.

What you should not do is get on an Inland Empire roof and start prying up Boral tile. Tile is brittle. The flashing underneath is usually nailed into the deck, and pulling the wrong nail in the wrong order creates three new leak points. Working on a roof in Riverside heat makes it worse: the tile gets hot enough to burn bare skin, and footing gets slick from dust and grit. Let us do the climbing and the cutting. If you suspect the flashing has failed, call (341) 208-3988 and describe what you see. We’ll tell you if it sounds like flashing or something else before we ever schedule a visit.
