Through The Roof! 14065 Sealant, Black, Liquid, 10.5 oz Cartridge

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.
