Replacing the roof on my 1995 Flair Fleetwood motorhome this method works for both EPDM and TPO roofs.
This is the roof kit i purchased for around $488.00 made by Lottes Roofing http://www.ebay.com/itm/10-x-30-45-Mi...
You will also need butyl tape or putty tape and probably extra lap sealant and extra seam tape.
