Sashco 14004 Cement and Patching Sealant, Clear, Liquid, 1 gal, Container

Through The Roof!® is the clear, ultra-elastic sealant made to permanently stop and prevent roof leaks. It effectively seals around a variety of roof fixtures without the messy look of asphalt. Plus, Through The Roof! won't dry hard and crack like traditional asphalt repair products and lasts 20 times longer. It expands and contracts with temperature changes, leaving you with a repair that sticks but won't stick out.
