Tamko Flashing Replacement: The Jacksonville Owner’s Guide

Tamko flashing replacement in Jacksonville typically costs between $380 and $780 installed, depending on where the flashing sits and how much of the surrounding shingle needs to be lifted. We keep Tamko-compatible flashing profiles on our trucks, so most jobs are completed same-day once we see the roof. You’ll have a written price in hand before any work starts.

Most Jacksonville homeowners discover a flashing problem the same way: a water stain on a bedroom ceiling after a hard rain, or granules collecting at the base of a downspout where the roof meets a wall or chimney. Flashing is the thin metal or composite material that seals the joints where your roof changes direction or meets something else. When it fails, water gets behind it. It’s rarely dramatic at first. By the time you see the stain inside, the flashing has usually been failing for months.

If you’re reading this because you found a stain, a lifted piece of metal, or cracks in the flashing around a skylight or chimney, you’re in the right place. This page covers what Tamko flashing replacement actually involves, what it costs in Jacksonville, and how to know if you need us at all.

Which Tamko Models This Applies To

Tamko flashing replacement applies to any roof system built with Tamko shingles, including the Heritage, Heritage Premium, Titan XT, and StormShield lines. The flashing itself isn’t made by Tamko. It’s selected to work with the shingle profile, so the key is matching the flashing material and dimensions to what’s already on the roof.

Here’s the compatibility detail most people miss: Tamko Heritage shingles have a specific exposure height, usually 5 5/8 inches, which means step flashing step increments need to follow that same line or the shingle tabs won’t lay flat. If the flashing step height is wrong, the shingle bulges slightly at each piece, and water eventually works its way in behind the bulge. We see this on Jacksonville roofs where a previous repair used a generic flashing rather than something sized for the shingle’s exposure.

For the OEM-vs-aftermarket question: Tamko doesn’t manufacture flashing, so there’s no “Tamko OEM flashing” to buy. What matters is material grade. We use 26-gauge galvanized steel for most replacements, which holds up against Jacksonville’s summer humidity and salt air far better than the 28-gauge material some builders used originally. In coastal-adjacent neighborhoods like San Marco and Riverside, we recommend moving up to aluminum flashing for the chimney and valley areas where salt exposure is highest. It costs more upfront but doesn’t develop the rust pinholes that eventually send water into the decking.

Birchbark Roofing Jacksonville is an independent roofing contractor, not affiliated with Tamko. We stock and install flashing that’s compatible with Tamko shingle profiles, and we work with other brands too: GAF, Owens Corning, and CertainTeed all sit on our truck alongside Tamko-compatible profiles.

Signs Your Tamko Flashing Replacement Is Failing

• Ceiling or wall stains near a chimney or skylight. This is the most common first sign. The flashing has separated from the surface behind it, and rainwater is finding an entry point. The stain appears below the actual leak point because water travels along rafters before dripping.
• Lifted, curled, or buckled flashing at roof-to-wall joints. Jacksonville’s summer heat expands metal flashing, and when it cools it contracts. Over a decade or two of that cycle, the metal loses its shape and begins pulling away from the wall. You can see this from the ground with a pair of binoculars.
• Rust streaks or pinholes on exposed chimney flashing. Near the St. Johns River and the beaches, salt in the air accelerates rust. Pinholes are small enough to hide behind the rust streak, but they’re large enough to let water in. This is a Jacksonville-specific failure pattern we see far more often than in inland cities.
• Granules piling up below a dormer or wall junction. Water getting behind flashing erodes the shingle’s granule layer as it runs down. By the time granules show up in the gutter or at the base of the roof, the leak has likely been active for months.
• Visible caulk or tar applied over flashing by a previous owner. Someone saw a problem and tried to seal it with a tube. It works for a season or two, then the sun breaks it down and the leak returns, usually worse because the sealant trapped moisture behind the flashing.

Replacement Cost & What’s Included

In Jacksonville, Tamko flashing replacement runs from $380 for a small, single-location step flashing repair to $780 for chimney or skylight flashing that requires removing and reinstalling shingles, underlayment, and sealant. Here’s how the cost typically breaks down:

• Basic step flashing swap (one wall junction): $380 – $520. Includes removing the old flashing, installing new 26-gauge material, resealing, and re-securing the shingles above.
• Chimney flashing replacement: $520 – $780. Includes counterflashing and reglet work around the chimney. Most expensive because it involves working at height and around the chimney crown.
• Skylight flashing replacement: $480 – $720. Cost depends on the skylight brand and whether the flashing kit needs to be ordered or is a stock profile we carry.
• Valley flashing replacement: $450 – $700 for a standard valley length. Price scales with the valley’s run length.

DIY or Call Us?

You can safely identify which flashing is failing by looking at your roof from the ground or checking ceilings and walls inside the house. Keeping the roof clean of debris, leaving flashing alone rather than caulking it, and watching for early signs is within any owner’s reach.

Actually replacing flashing means working at height, lifting shingles, and resealing joints. It’s not the kind of job that forgives mistakes. Homeowners who try it usually end up with a bigger leak than they started with, because the old sealant gets broken and the new sealant doesn’t cure properly in the Florida sun. Our crews include uniformed, background-checked technicians who walk the job with you before any work begins. Erik Lindgren has been on Jacksonville roofs for years, and if the job needs a ladder and a nail good enough to hold through a tropical storm, we’d rather you call us at (904) 604-7914. The estimate is free.
