Sashco Through The Roof Sealant, Brush Grade, 1 Quart Can, Clear (Pack of 1)
Wind gusts and weather changes put your roof and rooftop fixtures in constant dynamic motion. Asphalt roof caulks that dry out and crack can't absorb this movement, allowing leaks between your roof and plumbing vent, chimney, skylight, fan duct or dormer. Through The Roof! was made to permanently stop and prevent leaks around these rooftop items.
