ALCO 24/7 Roof Repair Tape

ALCO Roof Repair Tape

The revolutionary Leak and Seam Repair Tape for TPO, EPDM, and Metal Roots with Ultra Aggressive Sealability

ALCO 24/7 Roof Repair Tape is the most aggressive sealing tape available. Highly effective, long-term solution for repairing leaks on virtually all roofing materials, including TPO, EPDM, and metal.


ALCO 24/7 Roof Repair Tape
is also extremely effective in
below grade concrete wall
penetrations for water, sewer
and electrical service.



  • Perfect for reinforcing non-leaking seams and for additional security around curbs, vents, chimneys, AC systems, antennas, or any roof-penetrating devices
  • VOC-free and stable from -70° F to 200° F
  • Easy to apply to clean, dry surfaces
  • Flexible and readily conforms to shapes - making it well suited for gutter repairs, piping and other curved equipment
  • UV Resistant for assured longevity - available in two backing colors - white and black.
  • Ultra Aggressive Sealing properties means it can be effectively used to stop water or air penetration on many other surfaces, including cement, plywood, OSB, and metal.
  • Excellent for stopping leaks on mobile homes, RVs, vans, garden sheds, tarpaulins and some unpressurized piping.
  • Full ALCO Warranty - Ask your sales representative or visit our Web site for complete details.


  • MEASURE - Measure area of the leak you want the repair tape to cover.
  • CLEAN - Make sure the area to be repaired is clean and dry. Remove loose material. If there are any oil-based residues, remove them with the appropriate cleaners.
  • CUT & PEEL - Cut the required length of ALCO 24/7 Roof Repair Tape and remove release coating from the inward-facing of the tape.
  • APPLY - Press into place by hand.
  • ROLL OUT - Roll with a hand roller to force adhesive into any surface irregularities.

IMPORTANT: ALCO 24/7 Roof Repair Tape cannot be removed by hand from ANY surface to which it is applied. Removal of this material requires mechanical intervention or high-strength solvents. DO NOT apply our repair tape to any surface with the expectation that it will be readily removed without affecting the surface to which it is applied.
