Tamko Flashing Replacement: The Jacksonville Owner’s Guide
We stock and install Tamko-compatible flashing replacements across Jacksonville, with most residential jobs running $175 to $425 installed depending on the flashing type, roof pitch, and how much existing material has to come out. We keep common step flashing, pipe boot flashing, and valley flashing on our trucks, so a lot of Tamko flashing replacements in Jacksonville happen in one visit. You’ll usually find the problem the same way our customers do: a water stain on the ceiling after a hard Florida rain, granules collecting in the gutter, or daylight visible under a lifted shingle at a wall or pipe penetration.
Flashing is the metal or synthetic material that bridges the joints in your roof, the places where shingles meet a wall, chimney, pipe, or valley. Tamko’s flashing line is built to work with their shingle systems, and in Jacksonville’s climate, it takes a beating. Salt air near the beaches, daily UV exposure, and the afternoon downpours we get from June through September all work against it. When flashing fails, water gets in. When water gets in, the repair gets more expensive by the week.
Which Tamko Models This Applies To
Tamko produces flashing under their own name and specifies compatible flashing across their major shingle lines, including Heritage, Heritage Proline, and Elite Glass-Seal. The flashing itself generally falls into a few categories: step flashing for wall intersections, pipe boot flashing for plumbing vents, valley flashing for roof valleys, and drip edge along the eaves and rakes. If you have a Tamko roof in Jacksonville, the flashing was either Tamko-branded or a Tamko-specified equivalent, and the replacement has to match the profile and material or you get a leak at the joint.
Identifying the right part matters more than most homeowners expect. Pipe boot flashing comes in different diameters, usually 1-1/2 inch to 4 inch, sized to the vent pipe it seals. Step flashing comes in 4-inch, 6-inch, and occasionally 8-inch widths, and the gauge of the metal matters more than the brand stamp on it. For the OEM-versus-aftermarket decision, here’s what Travis Oakley tells customers: on a Tamko roof, OEM flashing preserves the manufacturer’s system warranty if you still have one, but a quality aftermarket flashing in the same gauge and profile will work fine and often costs less. In most cases around Jacksonville, roofs are past the manufacturer labor coverage window, so the practical question is material match and proper installation, not the label on the metal. We source Tamko-compatible flashing through our materials lines, which also include GAF, Owens Corning, and CertainTeed, so we can match what’s on your roof rather than forcing you into whatever happens to be on the shelf.

Signs Your Tamko Flashing Replacement Is Failing
- Water stains on interior ceilings or walls near roof edges. Flashing at wall intersections and valleys is the first place water finds a seam. A stain that appears within a day of heavy rain points to flashing, not a shingle issue.
- Lifted, curled, or separated flashing at the chimney or wall line. Jacksonville’s heat cycles cause metal flashing to expand and contract against the caulk or sealant holding it in place. Once the sealant cracks, the flashing lifts, and water follows.
- Rust or corrosion on metal flashing. Ocean salt air in neighborhoods like Atlantic Beach, Neptune Beach, and down toward Mayport corrodes galvanized flashing years faster than inland areas. Pitting at the nail heads is the first visual sign.
- Granules collecting in gutters or staining on the shingles below a pipe boot. Failed pipe boot flashing lets water run under the shingles, which breaks down the asphalt and washes granules toward the gutter line.
- Visible gaps where the flashing meets the structure. Caulk eventually dries, cracks, and pulls away. If you can see daylight or a gap wider than a nickel at any flashing junction, water is already working through it.

AfterReplacement Cost & What’s Included
Installed Tamko flashing replacement in Jacksonville typically runs $175 to $425 for a single flashing point like a pipe boot or a short step-flashing run. Larger jobs, like a full valley flashing replacement or re-flashing an entire chimney, can reach $600 to $1,200 depending on height, access, and how much shingle and underlayment has to be peeled back to do the work correctly. The variables are honest ones: roof pitch, number of stories, whether the decking underneath is still sound, and how much the old flashing fights us on the way out.
| Flashing Type | Typical Installed Range (Jacksonville) |
|---|---|
| Pipe boot flashing (single vent) | $175 – $275 |
| Step flashing (8 – 10 ft wall run) | $250 – $425 |
| Valley flashing (full valley) | $350 – $700 |
| Chimney re-flashing | $600 – $1,200 |
| Drip edge (per 10 ft section) | $150 – $250 |
Every quote goes on paper before any work starts, and that price does not move at the door. We are part of the Garrison Partners family, founded in 2000, and we operate under the Garrison Standard: written price first, background-checked uniformed technicians on your roof, and a 365-Day Done Right Promise on every repair. That means the flashing work is guaranteed in writing for one full year. If it fails inside that year, we come back at no charge.
DIY or Call Us?
You can safely identify a flashing problem from the ground or from a ladder held by someone else: look for lifted metal, cracked caulk, rust, or visible gaps at pipes and wall lines. What you should not do is walk a Jacksonville roof after rain, pull shingles, or attempt to replace flashing without the right tools and a plan for re-sealing the underlayment. Roofs here are steep in places, decking gets slick, and a wrong bend in a piece of step flashing turns a $250 repair into a $900 re-roof section.
If the flashing is accessible, you can check whether the boot is split, the caulk is cracked, or the metal has pulled away from the wall. Document what you see, keep it dry if you can, and call us at (904) 719-6346. Travis and his crew have been running flashing replacements across Jacksonville for years, and we’ll put a dollar range on it before we touch a nail.
FAQs
Tamko flashing installed correctly in Jacksonville typically lasts 15 to 25 years depending on exposure, with pipe boots wearing out faster than step flashing because of UV and heat at the roof surface. Coastal areas near the beach see accelerated corrosion, so we recommend an inspection every 3 to 5 years after year ten. Call (904) 719-6346 for a flashing inspection along with any other roof concerns, and we’ll give you the straight answer on condition and remaining life.
Small caulk cracks and minor gaps can be resealed as a stopgap, but in most cases flashing that has lifted, rusted, or separated needs actual replacement to stop water intrusion reliably. A patch job on corroded metal is a temporary fix at best, and in Jacksonville’s wet season a temporary fix becomes a ceiling stain. Call (904) 719-6346 and we’ll tell you honestly whether your flashing is repairable or needs to be swapped, with a written price either way.
A single point flashing replacement, like a pipe boot or a short step-flashing run, typically takes 1 to 2 hours, while valley or chimney re-flashing can run half a day to a full day depending on access and the condition of the surrounding shingles. We always confirm a written price before any work begins, so the schedule and the dollar amount are set before we show up. Call (904) 719-6346 and we’ll work a visit around your schedule.
We keep common sizes of step flashing, pipe boot flashing, valley flashing, and drip edge on our trucks for Jacksonville service calls, and we source Tamko-compatible material through our roofing manufacturer lines so the replacement matches your existing roof. For unusual profiles or oversized pipe boots we can usually have the part within a day or two. Call (904) 719-6346 with your flashing type and we’ll tell you what we have and what it will cost.
If you have a Tamko flashing problem in Jacksonville, call Brennan Roofing Co Jacksonville at (904) 719-6346. We’ll identify the failing part, put a written price in front of you before any work starts, and do the replacement under the Garrison Standard. If it’s not right, we’re not done.
