Roof and Flashing Sealant, flexible, weatherproof coating 1-Gallon

Roofing sealers and primers help maintain the weather barriers around roof penetrations and help roof tapes to adhere to dirty or porous surfaces. Roofing primers prepare a surface by binding with dirt particles and smoothing the surface. This creates a consistent, dirt-free surface for the roof tape to stick to. Roof sealers create flexible yet durable waterproof coatings and seals around ductwork, flashing, and other roof penetrations.
