If you plan to replace the entire existing membrane, consider the newest PVC membranes. They 'seem' to have a better warranty and are bright white, better at reflecting the sun/heat.
They do appear to be somewhat new on the market so not yet sure of their long-term life. Like TPO membranes, they need little to no maintenance vs EDPM.
There are also companies that do a thick, spray on roof coating (similar to a bedliner) and are guaranteed for life.
