FlashSeal is a versatile and easy-to-use flashing repair system that, when dry, forms a flexible, waterproof membrane. It’s formulated for permanent adhesion to asphalt shingles, metal flashings, brick, and other chimney and roofing materials. Use FlashSeal to solve problem leaks around the base of chimneys, stacks, and vents. It is also great for sealing around skylights.
Repairing flashings that have been tarred over, split, cracked, or are in disrepair is easy with FlashSeal.
It’s like installing a custom-fit rubber boot at the base of the chimney! It remains permanently flexible and has a 7 year warranty when used with FlashSeal Reinforcement Fabric.
