This is determined by the type of metal roofing you're installing, and also by the pitch of the roof. Generally, with the type of product I think you're talking about, a tape sealant is a good idea.
However, I cannot stress enough -- get full installation instructions from the manufacturer of the roofing. Read and follow them closely! This is critical.
