FlashSeal is a versatile and easy-to-use flashing sealant 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 elastomeric sealant to solve problem leaks around the base of chimneys, stacks, and vents. This elastomeric sealant 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! Flashing sealant remains permanently flexible and has a 7 year warranty when used with FlashSeal Reinforcement Fabric.
For complete chimney protection, we recommend waterproofing the chimney and sealing the chimney crown.
