The Gardner Black Jack Leak Stopper Roof Patch is a revolutionary rubberized roof repair solution designed to permanently stop leaks in wet or dry conditions. This fiber-reinforced patch uses Penetrex™, a unique penetrating oil formula that reaches deep into cracks and damaged areas to form a complete, lasting seal. Whether your roof is actively leaking or showing signs of wear, this flexible plastic cement bonds instantly to create a watertight barrier that prevents future water intrusion.

The rubberized composition stretches with roof movement, preventing the cracking and separation that plague traditional cement patches. Formulated to perform in both wet and dry conditions, the Black Jack Leak Stopper eliminates the need to wait for ideal weather to make repairs. The liquid rubber provides a flexible, high-performance plastic cement for a superior watertight bond that stops problem leaks for good.

Features and Benefits

  • Penetrex Technology: A unique penetrating oil formula that reaches deep into cracks and damaged areas to form a complete seal.
  • Rubberized Flexibility: The liquid rubber component allows the patch to stretch with the roof, preventing cracking.
  • Year-Round Application: Formulated to cure and perform in wet or dry conditions, so you can repair roof damage whenever needed.
  • Multi-Surface Compatibility: Works on shingles, built-up roofs, SBS modified roofs, metal roofs, and many other roofing materials.
  • Superior Watertight Bond: The flexible, high-performance plastic cement provides a lasting seal that stops problem leaks permanently.
