DAP Ultra Clear Roof Waterproof Rubberized Sealant is a crystal-clear, elastomeric synthetic rubber sealant designed to stop and prevent minor roof leaks around flashing, vents, chimneys, gutters, seams, and roof penetrations. Its 100% waterproof and weatherproof formula adheres to wet and damp surfaces, even through standing water, and provides immediate rain-ready protection. The sealant applies crystal clear, resists yellowing and UV exposure, and cures to a permanently flexible, crack-resistant seal. Suitable for all-weather application from 0°F to 120°F, it bonds to common roofing materials including metal, asphalt, PVC, and EPDM rubber. The convenient caulking cartridge provides controlled, precise application for targeted leak repairs. Intended for minor roof leaks and penetrations rather than structural roof repairs.
