Sealant is a flexible waterproof material used to close gaps, joints, and seams in roofing systems. It prevents water, air, and debris from entering vulnerable areas of the roof. Sealants are commonly used around flashing, vents, skylights, and fasteners. They must remain flexible to accommodate roof movement caused by temperature changes. In wet climates, high-quality sealants are essential for maintaining roof integrity and preventing leaks over time.
