Sashco 14065 Sealant, Black, Liquid, 10.5 oz, Cartridge (Pack of 12)

When there's a nagging roof leak that others can't fix, or when you don't want to take your chances, use Through The Roof®. Its unique co-polymer rubber formula creates a permanent seal, even when applied in the middle of a rain storm. (It works great on dry surfaces, too.) Through The Roof® will stick to almost any roofing surface metal, plastic, asphalt, wood, concrete, and more. Plus, it won't freeze. So go ahead and fix that gutter in a Minnesota winter.
