Boral Flashing Replacement: The Long Beach Owner’s Guide
Boral flashing replacement in Long Beach typically runs $220 – $480 installed for a standard penetration (pipe boot, vent, or chimney corner), and we stock Boral-compatible flashing on our trucks so most swaps happen the same visit. Flashing is the metal or composite material that seals the joints where your roof meets a pipe, chimney, wall, or valley, and when it fails on a Boral tile roof, water finds its way under the tile and into the deck. Most Long Beach homeowners discover the problem after a winter rain: a brown ceiling stain, peeling paint near a chimney, or water beading on attic sheathing. The good news is that flashing failure is a localized fix, not a roof replacement.
Which Boral Models This Applies To
Boral tile roofs, whether concrete or clay, all rely on flashing at penetrations and transitions. The Boral product line most common in Long Beach includes the Boral CedarLite, Boral Villa, Boral Saxony, and the flat-profile Boral Shake ranges. The flashing itself is not made by Boral; it is standard roofing metal (galvanized, aluminum, or copper) shaped to fit around the tile profile. What matters for compatibility is the pitch of your roof and the shape of the tile: a high-profile barrel tile like Villa needs a taller flashing base than a flat tile like Saxony.
On the truck we carry step flashing in 4-inch and 6-inch rises, 3-inch and 4-inch pipe boots in both galvanized and lead, and chimney saddle flashing cut to order. If your tiles are a discontinued Boral color, we match the flashing to the nearest stock color rather than trying to source an exact match, which keeps the job moving and the cost down.

Signs Your Boral Flashing Replacement Is Failing
- Water staining around a chimney or skylight after rain. This is the classic symptom: the flashing has pulled away from the mortar or the sealant has dried and cracked. On Boral tile roofs, the tile itself rarely leaks; the flashing does.
- Visible rust or corrosion on metal flashing. Salt air in Long Beach neighborhoods like Belmont Shore and Naples accelerates rust on galvanized flashing. Once rust perforates the metal, water seeps through pinholes.
- Lifted or curled flashing edges. Temperature swings cause metal to expand and contract. Over years, the fasteners loosen and the edge curls up, creating a gap for wind-driven rain.
- Granules or debris piling up at the base of a flashing joint. This usually means water is running underneath the tile and carrying sediment with it. The joint is no longer shedding water properly.
- Roof cement or caulk that is cracked and separating. If a previous repair relied on sealant instead of new metal, it will fail again, often within two or three seasons. Sealant is a temporary patch, not a flashing repair.

AfterReplacement Cost & What’s Included
For Long Beach homes, Boral flashing replacement installed by Crestview typically falls in these ranges:
| Flashing Type | Installed Price Range |
|---|---|
| Pipe boot (plumbing vent) | $220 – $340 |
| Step flashing (wall or sidewall) | $280 – $450 |
| Chimney corner or saddle | $350 – $520 |
| Valley flashing | $400 – $650 |
What drives the range: the number of tiles that must be removed and reset, the height and pitch of the roof, and whether the old flashing left water damage behind that needs deck repair. Every estimate includes the flashing, fasteners, sealant, tile removal and reset, and haul-away of old metal. You get a written price before any work starts, and the number on the page is the number on the invoice. The repair is covered by our 365-Day Done Right Promise: if it fails within a year, we fix it at no charge, including a free second visit.
DIY or Call Us?
You can safely inspect your own flashing from the ground with binoculars: look for lifted edges, rust streaks, and cracked sealant at every pipe, vent, and chimney. What you should not do is climb onto a tile roof. Boral tile is brittle, and walking on it without a tile walkway or proper weight distribution breaks tiles faster than the flashing will ever fail. We see more tile cracks from well-meaning DIY checks than from actual weather.
Replacing flashing on a Boral roof means pulling the tiles around the penetration, cutting and bending metal to fit the profile, replacing underlayment if it is torn, and resetting the tiles with the correct embedment. If the underlayment is compromised, a patch job will leak again within a season. If you want an honest look at what is actually failing, call Dylan and the crew at (562) 471-4832 and we will put it in writing before any work starts.
FAQs
Galvanized flashing in Long Beach’s coastal environment lasts 15 – 20 years on average before corrosion or fastener failure sets in. Aluminum lasts longer, often 30-plus years, but costs more. Proximity to salt air in Belmont Shore and the Peninsula shortens galvanized lifespan compared to inland neighborhoods like Bixby Knolls.
Small gaps can be resealed as a temporary fix, but sealant alone fails within two to three seasons. If the metal is rusted through, cracked, or pulling away from the joint, replacement is the only repair that holds. We do not sell patch jobs that will fail.
A standard pipe boot or step flashing swap takes one to two hours on a Boral tile roof. A chimney saddle or valley replacement can take a half day, depending on tile removal and deck inspection. You will know the time window before we start, and you can track our arrival time through The Relay Standard.
We stock galvanized and aluminum flashing in the sizes Boral tile profiles require on our trucks in Long Beach. Copper is available but special ordered. If your tile color is unusual, we match the flashing to the closest stock color to keep the repair same-day.
If I wouldn’t put it on my own roof, I’m not putting it on yours.
