People Also Ask

PERMAPATCH™-N is a nylon-reinforced elastomeric roof patch designed to repair and waterproof common roof problem areas. It is ideal for sealing cracks, holes, flashings, roof penetrations, seams, valleys, vents, and other areas where leaks may develop. Once cured, it forms a durable, flexible rubber-like seal that expands and contracts with temperature changes to help maintain a watertight repair.

PERMAPATCH™-N adheres to a wide variety of properly prepared roofing surfaces. It can be used on asphalt roofing, modified bitumen, metal roofs, galvanized steel, aluminum, fiberglass, concrete roof tiles, clay tiles, slate, weathered wood, built-up roofing (BUR), properly prepared EPDM, and many other common roofing materials. This versatility makes it an excellent repair product for residential, commercial, and industrial applications.

The built-in nylon fibers provide additional strength and durability compared to standard roof patch compounds. They help bridge small gaps, improve crack resistance, reduce sagging, and reinforce repaired areas against movement caused by weather and thermal expansion. The result is a stronger, longer-lasting roof repair.

Yes. After the patch has dried properly, PERMAPATCH™-N can be top-coated with most compatible acrylic roof coatings or latex coatings. Applying a compatible roof coating over the repair helps provide a uniform appearance while adding additional long-term weather protection to the repaired area.

PERMAPATCH™-N is ready to use right out of the container—no thinning is required. Apply it with a stiff brush or trowel to a clean, dry surface. For deeper repairs or larger voids, multiple applications may be needed to build the repair to the desired thickness. Drying time depends on temperature, humidity, and application thickness, so always allow adequate curing before applying a finish coating.
