Found some interesting information that will help educate the public. The following are definitions from MBMA (Metal Building Manufacturers Association) Metal Building System Manual. The definitions define the 2 basic types of standing seam roof panels.
Metal panel systems that are designed to withstand being submersed in water for a period of time are called hydrostatic panels. Hydrostatic roof details rely on sealant to keep water from infiltrating the joints and seams. Hydrostatic roof details can be used at almost any slope (1/4:12 minimum).
Metal panel systems that are designed to shed water are referred to as hydrokinetic. Hydrokinetic roof details are typically devoid of sealant and rely on water to freely shed over the joints. Hydrokinetic roof details are not to be used on roof slopes below 3:12.
