Through the roof is the clear, ultra-elastic sealant made to permanently stop and prevent roof leaks

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 wont 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 wont stick out. Conforms to ASTM C794
