Benefits of Henry leak repair systems:

  • Ease of use—designed for easy application — during preventive maintenance or emergency leak repairs—on almost any roof surface.
  • Versatility—use to repair leaks around flashings, chimneys, vents, skylights, joints in metal edging, gutters, or any other typical rooftop penetration.
