A roof jack is the metal termination that turns a vent pipe into a weatherproof, pest-proof exit through the roof. When the jack is damaged, missing flashing, or installed without a bird guard, you get two problems at once, roof leaks and vent blockages. In Florida, sun, wind, and driving rain accelerate both.
A proper roof jack installation fixes the leak, restores airflow, and stops nesting for good. We match the jack to your vent diameter, flash the penetration correctly, seal it to resist wind-driven rain, and top it with a bird guard that still allows full airflow.
Professional roof jack installation solves these problems by:
If your roof has stains around a vent pipe, or nests on top of the jack, this is the fix.
Watertight
Flashed and sealed to resist storms
Bird-Proof
Integrated bird guard on every install

You see exactly what we find and verify every vent is completely clear.
Soft brush removes clumps, metal brush polishes the pipe interior so lint won't stick.
Most companies skip this. We don't. Lint builds up inside the machine, not just the vent.
We plan our routes so we're never late. Most customers see us 15–20 minutes early.
If you're not happy, we come back. No arguments, no charges.
We use Florida building code metal piping on every job. Never foil, never PVC.
How do you know your roof jack needs replacing?
Brown rings or water spots near a vent pipe usually trace back to a failing roof jack.
An exposed jack without a guard is prime real estate for birds, and a major airflow blockage.
Sun and salt air break down old galvanized jacks. Rust streaks on the roof are an early sign.
If the flashing is pulling up, sealant is cracked, or shingles are curling around the jack, it is time for replacement.
Hurricanes, tropical storms, and high-wind events routinely damage roof jacks, inspections after are worth it.
A jack that does not match the vent diameter chokes airflow and guarantees lint buildup at the roof.
Any of those call for an inspection. Replacing a roof jack is usually a one-visit job and often cheaper than a single interior drywall repair from a leak.
Every roof jack installation follows the same disciplined, leak-proof process.
We inspect the existing jack from the roof and the ceiling or attic side, looking for leaks, rust, cracks, and undersizing.
The old jack, flashing, and any deteriorated sealant are removed. We lift shingles carefully without damaging them.
The roof deck is cleaned, dried, and checked for damage. Any minor sheathing issues are addressed before the new jack goes on.
A new jack is installed, sized to your vent, with proper flashing shingled in over and under so water cannot migrate under the roofing.
An integrated bird guard is attached (or built in), and all exposed edges are sealed with weather-rated, UV-resistant sealant.
We leak-test the penetration with water and walk you through before-and-after photos of the roof and the duct inside.
Most roof jack installations take 60–90 minutes. We are fully insured and carry the safety gear to work safely on Florida-pitch roofs.
Before & after installation, old rusted roof jack replaced with a new bird-guarded, properly flashed termination, watertight, pest-proof, and code-compliant.
