Lap Joint Nozzle System with Through The Roof! Sealant

Cobra Lap Joint Nozzle extrudes a wide bead to easily cover all kinds of lap joints such as roof flashing and window fins, and sandwich joints such as thresholds. The Cobra's arched profile delivers a bead thicker in the middle and thinner on the edge. This helps place the mass of material where you need it, exactly over the lap joint itself. 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. Conforms to ASTM (American Society for Testing and Materials) C794. Sticks to surfaces wet or dry, in temperatures down to 0 F and up to 120 F. It has tenacious adhesion to a wide variety of roofing materials and won't discolor them.
