Owens Corning Flashing Replacement: The Fort Lauderdale Owner’s Guide
Replacing failed flashing on an Owens Corning roof system in Fort Lauderdale typically runs $350 – $900 installed, depending on location, linear feet, and whether we’re dealing with step flashing, pipe boot flashing, or valley metal. We stock Owens Corning-compatible flashing on our trucks, so most Fort Lauderdale jobs are done in a single visit, usually within two to four hours once we’re on site. You’ll usually discover the problem the same way most homeowners do: a brown water stain on the ceiling after a hard Florida downpour, or granules collecting in the gutter near a wall junction and that nagging sense that water is finding a path it shouldn’t.
Flashing is the metal (or synthetic) material that bridges the gap where your roof meets something vertical: a wall, a chimney, a skylight, a vent pipe. When it fails, water gets behind your Owens Corning shingles and into places shingles were never designed to protect. In Fort Lauderdale’s salt air and afternoon thunderstorm cycles, flashing takes abuse that inland roofs never see.
Which Owens Corning Models This Applies To
The flashing on your roof isn’t stamped with an Owens Corning model number the way a shingle bundle is. What matters is matching the flashing profile and material to the Owens Corning system you have installed, because the shingle profile affects how step flashing seats against the wall. We work with Owens Corning Duration, Oakridge, and TruDefinition Duration series roofs throughout Broward County. The key identifier is usually the shingle thickness and exposure: Duration shingles have a thicker butt edge that requires slightly taller step flashing (typically 4-inch wall leg, 4-inch roof leg minimum) compared to what you’d spec on a three-tab roof.
Here’s the compatibility gotcha most Fort Lauderdale homeowners hit: aluminum flashing corrodes faster in coastal salt air. If you’re within three miles of the beach, we recommend replacing aluminum step flashing with galvanized steel or copper-baked alternatives, even if the original installer used aluminum to match an Owens Corning aesthetic. It’s a small material upgrade that adds years in this climate. The other gotcha: pipe boot flashing (the rubber collar around plumbing vents) dry-rots in South Florida UV within eight to twelve years, and the rubber collar itself is replaceable without touching the shingles around it, if you catch it early.
We’re an independent roofing contractor in Fort Lauderdale. We install and service Owens Corning systems regularly, but we’re not affiliated with Owens Corning directly, and we don’t need to be: the flashing we use meets or exceeds the specs called for in Owens Corning’s installation guides.

Signs Your Owens Corning Flashing Replacement Is Failing
- Water stains on ceilings or upper wall corners after heavy rain. This almost always traces to failed step flashing where a roof plane meets a vertical wall. Water rides the wall down, finds the gap, and presents as a ceiling stain that worsens after consecutive storm days.
- Granules collecting in gutters near wall or chimney junctions. When flashing channels water under shingles rather than over them, the shingle edges along the junction start losing granules and curling. That grit in the gutter is shingle material leaving your roof.
- Rust streaks or white corrosion powder on exposed flashing. In Fort Lauderdale’s humidity and salt air, galvanized flashing eventually sacrifices its coating and starts oxidizing. Once you see rust bloom, the metal is actively thinning, and pinholes follow quickly.
- Caulk peeling or separating around pipe boots and vent collars. The rubber collar shrinks and cracks in Florida heat. When the caulk bead between the collar and the pipe lifts, water rides straight down the pipe into the attic. This is one of the most common, cheapest-to-fix leaks we see.
- Daylight visible from the attic at wall or chimney intersections. If you’re comfortable in the attic with a flashlight, train it where the roof meets any vertical surface. Seeing slivers of light means the flashing has separated badly enough that rain will absolutely find its way in.
Replacement Cost & What’s Included
| Repair Type | Typical Installed Range (Fort Lauderdale) |
|---|---|
| Single pipe boot flashing replacement | $185 – $275 |
| Step flashing replacement, 10 linear ft wall | $300 – $500 |
| Chimney flashing full replacement (4 sides) | $600 – $900 |
| Valley metal replacement, 20 linear ft | $550 – $850 |
| Skylight flashing replacement | $400 – $700 |
Those Fort Lauderdale ranges include parts, labor, disposal of the old material, and our written workmanship warranty. The spread comes from accessibility: a one-story roof with an easy pitch runs at the low end, while a steep two-story section or a chimney that needs new counter-flashing cut into mortar will push toward the top. We bid by the linear foot and the number of flashing elements, not by guesswork. You’ll get a written price before any work starts, and that number is the number on the invoice. That’s the Relay Standard, and it’s not optional on our jobs.
Every flashing replacement we install is covered by our 365-Day Done Right Promise: if it fails within a year, we come back and fix it at no charge, including a second visit if the repair doesn’t hold. That’s in writing, on every job, with no fine print about “acts of God” exclusions for normal rain events.
DIY or Call Us?
Some things on a roof are safe to inspect from the ground with a pair of binoculars: visible rust on chimney flashing, lifted pipe boot collars you can spot from the lawn, granules in the gutter. But flashing replacement involves lifting shingles, cutting metal, and working on a sloped surface, often two stories up, with Florida sun baking the deck. That’s not a Saturday project. Ladder safety, tear-off damage to surrounding shingles, and improper lapping that you won’t discover until the next storm all make this a job where the cost of a professional is cheaper than the cost of a mistake.
What you should do is call us while you still have a small problem instead of a big one. The pipe boot collar that’s cracking today is a $225 fix now and a $1,200 drywall and insulation remediation six months from now. Call (754) 354-8628 and we’ll give you a straight answer on what needs replacing and what it costs before we ever set foot on the ladder.
How Long Does Flashing Replacement Last in Fort Lauderdale?
Galvanized steel step flashing in Fort Lauderdale lasts 15 to 25 years if properly installed; aluminum closer to the coast can start pitting in 8 to 12 years due to salt exposure. Pipe boot rubber collars are the weak link and typically need replacement every 8 to 12 years regardless of what shingle system you have. We’ll tell you which material your existing flashing is made of and whether it’s worth upgrading to something that’ll outlast the roof.

AfterCan Flashing Be Repaired Instead of Replaced?
Sometimes. Small gaps at pipe boot collars can be resealed with a high-quality roofing sealant as a temporary measure, and individual step flashing pieces can be replaced without redoing an entire wall junction. But if the flashing is rusted through, bent, or if multiple pieces have shifted, partial repairs usually buy you less than a year before the problem returns. We’ll show you photos of what we found and give you our honest recommendation, whether that’s a spot fix or a full replacement.
How Long Does the Actual Replacement Take?
A single pipe boot replacement takes under an hour once we’re on the roof. Step flashing along one wall typically takes two to four hours including tear-out, new flashing install, and resealing the shingle courses. A full chimney flashing job with counter-flashing cut into the mortar can run four to six hours. You’ll have a live trackable arrival time before we get there, and before-and-after photos sent to your phone when the work is done, so you can see exactly what was replaced even if you never climb a ladder.
Do You Stock Owens Corning-Compatible Flashing on the Truck?
Yes. Our trucks carry galvanized step flashing in the common 4×4 and 5×7 sizes, pipe boots in 1-1/2″, 2″, and 3″ diameters, and valley metal in standard 10-foot lengths. That means most flashing replacements in Fort Lauderdale are completed the same day we diagnose the problem. We also work with GAF and CertainTeed systems regularly, so if your roof has a mix of brands or we need to match an unusual flashing profile, we can order it and have it in hand before scheduling the install.
Will the Price Change Once Work Starts?
No. The written estimate you approve is the price you pay. If we open up the area and find additional damage underneath, we stop, show you photos, and give you a new written price for the additional scope before we do anything else. You’re never billed for surprises that weren’t approved in advance. As Dylan Pace puts it: “If it’s not in writing, it’s not a promise.”
If you have a leak, a stain, or any suspicion your flashing is failing on your Owens Corning roof in Fort Lauderdale, call (754) 354-8628 for a free estimate. We’ll diagnose what’s failing, give you a written price, and get it fixed before the next storm system rolls through.
