Butyl tape:

Is sealant able to form an instant and permanent bond to any clean and dry surface, but it remains flexible even after withstanding fluctuating conditions. This sealant is also extremely weather-resistant because it self-heals, which means bolts and fasteners won’t hinder its sealing abilities. That makes it particularly valuable for roofing applications as installation, and even reinstallation down the line, will not compromise its durability.
