ChimneyRx® Elastomeric Flashing Sealant is an elastomeric sealant specially formulated to permanently adhere to asphalt shingles, aluminum flashing, brick and other chimney and roofing materials.

Faulty or deteriorated flashings can cause leaks and water damage to the surrounding roof deck or eventually the interior finishes of your home.

Sealing Chimney Flashing that Resists Cracking

Unlike tar-based sealers, ChimneyRx® Elastomeric Flashing Sealer is an elastomeric-based material that remains flexible over longer periods of time. When applied, it will resist the typical brittleness and cracking associated with tar-based sealers that ultimately leads to their failure and need for replacement.

ChimneyRx® Elastomeric Flashing Sealant is excellent for use in stopping problem leaks around the base of chimneys, stacks and vents. When used to repair chimney flashing leak at the base of a chimney, ChimneyRx® Elastomeric Flashing Sealant provides a weatherproof “boot of protection” for the chimney. It is also great for sealing around skylights. Repairing flashings that have been tarred, re-tarred or cracked has never been so easy.

Available in 1/2 gallon plastic containers, each container covers approximately 14 linear feet.
