Boral Flashing Replacement in Los Angeles, CA

Boral Flashing Replacement: The Los Angeles Owner’s Guide

Boral flashing replacement in Los Angeles typically runs $340-$780 installed, depending on roof pitch and accessibility, and we carry matching profiles for same-day repair on most Boral tile systems. If you’ve spotted water staining on your ceiling after the last Santa Ana wind event, or noticed lifted tiles along a valley or wall junction, failed flashing is the most likely culprit. A roof doesn’t lie - it just waits until the rain to tell you the truth.

Which Boral Models This Applies To

Boral’s clay and concrete tile lines have been installed across Los Angeles since the 1980s, and flashing profiles vary by tile height and lock style. The most common systems we service in the San Fernando Valley and Pasadena areas are Boral Saxony 900 (low-profile concrete), Boral Barcelona (medium-profile clay), and the older Boral Villa 900 series still found in original construction from the 1990s through mid-2000s.

Identifying your flashing starts with the tile itself. Lift one carefully from the eave and check the underside for a stamped Boral logo and series name. The critical measurement is the tile height at the lock - this determines whether you need a standard 1-inch rise flashing or the deeper 2-inch profile used on Barcelona and similar medium-weight tiles. Mix these up and you’ll get wind-driven gaps or broken tiles inside two seasons.

We source OEM Boral flashing where the series is still in production, and for discontinued lines we fabricate matched equivalents from 26-gauge Kynar-coated steel in the identical profile. Pete Navarro learned early in his career that substituting a generic valley flashing on a Boral system to save forty dollars usually costs the homeowner eight hundred when the tiles crack. We don’t do that.

Signs Your Boral Flashing Replacement Is Failing

• Water stains on interior ceilings or walls below roof intersections. The most common call we get after the first winter rains in Los Angeles. The flashing’s seal has degraded at the wall or chimney junction, and water is tracking along the underlayment until it finds an entry point inside.
• Lifted or cracked tiles along valleys, ridges, or vertical walls. When flashing corrodes or its fastening flange pulls free, tiles lose their seating and rock in the wind. The Santa Anas will finish what the loose flashing started.
• Visible rust streaks or orange staining on tile surfaces below metal flashing. Boral’s original galvanized steel flashing from the 1990s and early 2000s has reached end of life in our coastal and smog-exposed climate. Once rust blooms through, the metal is thinning fast.
• Granule or debris accumulation in valleys that seems to return after cleaning. This usually means the valley flashing has buckled or its edge has lifted, creating a trap where leaves and grit collect and hold moisture against the metal.
• Daylight visible from the attic at wall or chimney junctions. The flashing’s step or counterflashing has separated from the masonry or siding. In Los Angeles, this often follows minor earthquake settling or thermal cycling of stucco exteriors.

Replacement Cost & What’s Included

What drives the range: accessibility (steep pitches in the Hollywood Hills or tight canyon lots in Laurel Canyon add labor time), whether we can match existing tile color or need to blend from a different lot, and the condition of underlying underlayment. Every estimate includes removal of failed flashing, installation of new Boral-compatible profile, ice-and-water shield at critical junctions, tile reset or replacement of cracked pieces, and photo documentation. Our 90-Day Done Right Promise covers the workmanship - if it’s not right, we make it right, no paperwork runaround.

DIY or Call Us?

Here’s what you can safely check yourself: from the ground with binoculars, look for the symptoms above. From inside the attic during daylight, note any light penetration at wall junctions. That’s the extent of it we recommend.

Flashing replacement on a Boral tile roof is not a homeowner project. The tiles must be carefully lifted without cracking - clay especially - and the underlayment beneath inspected for secondary damage. Working on a pitched tile roof requires proper ladder placement, roof brackets, and experience with the weight distribution of stacked clay. We’ve been called to jobs in Los Angeles where a homeowner’s foot went through underlayment they didn’t know was compromised, turning a $400 flashing repair into a $3,000 sheathing job. The price we quote is the price you pay. Call (844) 563-1816 and we’ll get you scheduled.
