    ChimneyRx Elastomeric Flashing Sealant is specially formulated to permanently adhere to asphalt shingles, aluminum flashing, brick and other chimney and roofing materials to repair chimney flashing leaks. 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 barrier for the chimney. It is also great for sealing around skylights.

    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 prevents faulty or deteriorated flashings from causing water leaks and water damage to the surrounding roof, deck, and eventually the interior furnishings of the home.

    Additional Information:

    • Stays Flexible
    • Easy Brush Application

    • Stops Leaks from Flashings Around Chimneys, Stacks, & Vents
