Boral Flashing Replacement: The Jacksonville Owner’s Guide
Boral flashing replacement in Jacksonville typically runs $340 – $680 installed for a standard penetration (pipe boot, vent, or valley section), and we stock Boral-compatible flashing on our trucks for same-visit replacement in most cases. Most Jacksonville homeowners discover the problem the hard way: a brown ceiling stain after a hard summer downpour, or granules washing out of a valley. Flashing is the metal or synthetic transition material where your Boral roof meets a wall, chimney, skylight, or pipe, and when it goes, water doesn’t wait for a convenient time to find its way in.
Which Boral Models This Applies To
Boral roofing products in Florida run through a few distinct lines: Boral concrete and clay tile (think the barrel and flat profiles common in Mandarin and Ortega), Boral stone-coated steel (the shake and shingle profiles you see on custom builds along the Intracoastal), and Boral’s composite underlayment systems that pair with both. Each uses different flashing geometry. Tile roofs need step flashing tucked under each tile course and over the next; stone-coated steel panels need a different reveal and fastener pattern than standing seam or shingle. The compatibility gotcha we see weekly: a homeowner or handyman grabs standard galvanized step flashing from a big-box store and the profile doesn’t match Boral’s tile curvature. Water tracks behind the flashing at the first wind-driven rain. If you can find the manufacturer’s label on an undamaged section, or measure the tile’s rise and barrel depth, that settles the question fast. We’re an independent Jacksonville roofing contractor, not a Boral affiliate, and we carry both OEM-spec Boral flashing profiles and tested aftermarket equivalents that match the original dimensions. Where OEM is available, we quote it. Where a quality aftermarket piece does the same job for less, we tell you that too, with the spec written on the estimate.

Signs Your Boral Flashing Replacement Is Failing
- Ceiling stains inside, usually after rain with wind. Flashing failure sends water sideways, not straight down. The stain often appears several feet from the actual breach, which is why guessing wrong makes the problem repeat.
- Granule loss concentrated at a valley or wall junction. Constant water sheeting scours the tile or steel surface there. You’ll see bare spots or bright metal at exactly the transition line where flashing should be carrying the water away.
- Visible rust or corrosion on exposed flashing at the chimney or pipe collar. Jacksonville’s salt-heavy air near the beaches and the St. Johns accelerates corrosion on galvanized metal. Once rust scales, the metal thins and pin-holes form.
- Lifted or curled flashing edges you can see from the ground or a ladder set safely back. Thermal cycling in a Florida attic plus afternoon heat expands and contracts the metal. Over years, fasteners back out and edges curl up off the tile like a dry leaf.
- Daylight or gaps where flashing should tuck tight against a sidewall or skylight curb. If the flashing isn’t lapped correctly into the Boral profile, you’ll see a shadow-line gap. That gap is an open invitation every time a summer squall comes through at forty miles an hour.
Replacement Cost & What’s Included
For Boral flashing replacement in Jacksonville, the installed price breaks down roughly like this:
- Pipe boot or plumbing vent collar: $180 – $300 installed
- Chimney flashing (full re-flash, one side): $350 – $600 installed
- Sidewall or step flashing replacement (10 linear feet): $300 – $520 installed
- Valley flashing or skylight curb re-flash: $450 – $750 installed
- Full perimeter re-flash with counterflashing (larger tile roofs): $1,200 – $2,400 installed
The spread comes down to access (a 12/12 tile pitch on a two-story Mandarin home costs more in labor than a walkable 4/12 in Arlington), how many linear feet of metal actually has to come out, and whether the decking underneath has already rotted. About half of what we quote is material; the rest is labor, prep, and disposal. Every price goes in writing before any work starts, and it doesn’t move at the door. The job includes removing the failed flashing, checking the decking and underlayment beneath it, installing the replacement flashing to Boral’s profile spec, then testing the transition with water before we come down. All of it is covered by the 365-Day Done Right Promise: one full year, in writing, with a free return visit if the repair fails.

Flashing replacement on a Boral tile or stone-coated steel roof is one repair where the honest answer is: don’t. Unlike a shingle roof where you can bend shingles back and slide flashing in, Boral tile and steel panels don’t flex. Forcing them breaks the tile or deforms the steel permanently. Working on a tile roof also means walking and kneeling on a surface that cracks under point loads, and a Jacksonville afternoon sun makes the tile hot enough to cook on. If you want to verify the problem before you call, stay on the ground: check for ceiling stains, look for rust or lifted edges visible from the ground, and check the attic for water trails on the underside of the decking near any wall or chimney. That’s useful information to have when you call. The actual removal and re-installation is a job for someone who works that profile every week. Travis Oakley and our crew have been on Boral roofs across Jacksonville for years, and we’ll tell you straight whether flashing is even your problem before we quote a dollar. Call (904) 719-6346 and we’ll schedule the inspection.
FAQs
In Jacksonville’s heat and salt air, OEM Boral flashing typically lasts 15 – 20 years before it needs replacement, while poorly matched or thin aftermarket flashing can fail in 5 – 7. If you’re near the Intracoastal or the ocean, subtract a few years and inspect more often. Call (904) 719-6346 and we’ll tell you what yours looks like from the ground and the attic before quoting anything.
Small fastener pops and minor lifting can sometimes be resecured, but most flashing failures in tile and stone-coated steel roofs are failures of the metal itself or the lap geometry, which means repair just moves the leak. If we can honestly seal it and stand behind it, we’ll tell you that and quote the smaller number. If it needs full replacement, we’ll show you why on the estimate.
A single penetration like a pipe boot or vent collar runs 1 – 2 hours on site; a chimney or full valley re-flash runs half a day to a full day depending on access and decking condition. You’ll have the written price before any work starts, so there’s no clock running on surprises.
We stock the most common Boral tile and stone-coated steel flashing profiles on the truck, including pipe collars, step flashing, and chimney counterflashing. Unusual profiles or OEM-specific pieces we order with a two-to-four day turnaround, and the lead time goes on the estimate in writing before you commit.
