IKO Flashing Replacement Nationwide

IKO Flashing Replacement: The West Palm Beach Owner’s Guide

IKO flashing replacement in West Palm Beach typically runs $350 to $900 installed, depending on the flashing type, roof pitch, and how much surrounding material has to come apart to do the job right. We stock IKO-compatible flashing on our trucks and can usually get the work done the same day we diagnose it. Most owners find out their flashing has failed the hard way: a water stain on the ceiling after a hard Florida downpour, or granules collecting in the gutter below a spot that never quite dried out.

Flashing is the metal or synthetic material that bridges the joints where your roof meets something vertical, think chimneys, skylights, vent pipes, and walls. When it fails, water gets under the shingles and into places it was never meant to go. In West Palm Beach, where afternoon thunderstorms dump an inch of rain in twenty minutes, failed flashing doesn’t wait around. Travis Oakley has pulled apart enough of these to know that most flashing failures in this region trace back to one of three things: age, improper installation, or the relentless expansion and contraction that comes with 90-degree days and 70-degree nights.

Which IKO Models This Applies To

IKO flashing isn’t specific to a single shingle line. The compatibility question is about the roof assembly itself: the underlayment, the shingle profile, and the penetration type. We install flashing that works with IKO Cambridge, Dynasty, Nordic, and Marathon lines, among others, and the fit depends on the slope and the surrounding material. If your home in West Palm Beach was built with IKO shingles, the flashing is almost always a universal-style piece like step flashing, pipe boot flashing, or chimney flashing rather than an IKO-branded part. What matters is the gauge, the material, and the profile: IKO’s own installation guidelines call for corrosion-resistant metal, usually 26-gauge galvanized steel or aluminum, with a minimum 4-inch step flashing overlap. We match that spec exactly, and we source from IKO and other leading manufacturer lines including GAF, Owens Corning, and CertainTeed. One compatibility gotcha that trips up do-it-yourselfers: Florida code and IKO’s own spec require step flashing pieces to extend at least 4 inches up the vertical wall and 4 inches onto the shingle course below. If the old flashing was cut short, water works its way in behind the siding, which is a slow leak that can go unnoticed for years, and by the time you see it, the decking underneath is shot.

We’re an independent service provider, not affiliated with IKO. That independence means we can tell you plainly whether a like-for-like replacement or a better materials upgrade makes more sense for your house.

Two Ways to Do This Job

You’ll generally choose between OEM IKO-compliant flashing and a quality aftermarket equivalent. Here’s the honest take: for most West Palm Beach homes, the aftermarket galvanized or aluminum flashing we install meets or exceeds IKO’s own installation specs at a lower price, and it lasts just as long in this climate. The places where we’ll push you toward a heavier gauge or a specific material are the ones where Florida eats metal: within a mile of the coast, salt air accelerates corrosion, so we recommend 24-gauge or thicker aluminum on homes in those zones. The difference in lifespan can be a decade. That’s not an upsell. It’s math.

Signs Your IKO Flashing Replacement Is Failing

• Water staining on ceilings or walls near chimneys, skylights, or dormers. This is the classic tell. The flashing has separated from the shingle or the vertical surface, and rainwater is running down behind it. By the time the stain shows, the leak has usually been active for weeks or months.
• Rusted, cracked, or lifted flashing metal visible from the ground or a ladder. Florida’s heat causes metal to expand and contract, and after enough cycles, the nails back out and the flashing lifts. Rust means the protective coating is gone and the metal is losing its fight against moisture.
• Granules from the shingles collecting in gutters near flashing points. When flashing lifts, it exposes the shingle edges to wind-driven rain, which scours granules loose. If you see a concentrated pile of granules below a chimney or vent pipe, that’s a flashing problem, not just shingle wear.
• Damp insulation or a musty smell in the attic after rain. Water that gets past flashing doesn’t always show up on the ceiling. It runs along rafters and soaks into insulation, where it breeds mold. We find this a lot in Northwood Hills, where the mix of older flat roofs and updated tile work creates joints that require careful flashing work.
• Daylight visible through the roof deck from inside the attic. If you can see light where flashing should be sealing a gap, you’ve got an open channel for water. This is the most serious warning sign, because it means the seal has failed completely.

Replacement Cost & What’s Included

The installed price for IKO-compatible flashing replacement in West Palm Beach generally falls between $350 and $900. The range depends on what we’re replacing. A single pipe boot flash runs $350 to $500. Step flashing along a chimney or wall runs $500 to $800. A full chimney flashing rebuild, with new counterflashing cut into the mortar, runs $700 to $900. High or steep roofs add labor, and removing tile or stucco to access the flashing adds cost.

DIY or Call Us?

There’s an honest split here. You can safely check from the ground or a ladder: look for lifted, rusted, or missing flashing around vents, pipes, and chimneys. You can also inspect the attic for damp spots after rain. That’s diagnosis. It’s free and it’s useful.

Replacement is a different conversation. Flashing work means lifting shingles, cutting new metal, and in many cases, working on a ladder against a wall at roof height. The biggest risk isn’t the cutting; it’s the fall, and it’s the water damage that comes from a seal that was just slightly off. If the flashing isn’t set exactly right, the leak comes back, usually worse, and the shingles you disturbed along the way may not reseat. We see this in West Palm Beach regularly: a homeowner spends a Saturday and $80 at a big-box store, and six months later there’s a new water stain in the same spot. For a job this unforgiving, the math favors a pro.
