I've looked in to this and it looks straightforward enough that me and a friend could replace my rubber roof with new EPDM.
My question is that I know it has a slight pitch to direct rain water towards the drain, but what was used to shape the roof? When I bought the house the inspector said something about foamboard? I was thinking of using wedges to nail to the top of the joists that the underlayment will lay on...It would be easy enough to create the slight pitch that way.
