Henry® Leak Repair Systems

The Henry full line of quality leak repair products are designed to get the job done right...the first time. Formulated for all types of applications and weather conditions, Henry roof cements, mastics, and patching fabrics repair holes, cracks, and splits in asphalt, metal, composition, SBS modified bitumen, and many other types of roofs.

 

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.
  • Quality—formulated for all weather conditions—whether you need to seal vertical flashing on a hot day, or repair a leak under ice-cold water, Henry has the right product to do the job.
