One advantage of an EPDM roof is that the average sheet size can be quite large. Whereas the standard TPO system comes in rolls of 5, 8, 10, or 12 feet wide (by 50 or 100 feet long), an EPDM sheet can easily be ordered in a 50 foot by 50 foot section. This allows for fewer seams than its TPO counterpart.
