Genecop - Roger on the sag. I am going to pull the AC cover off today (if it stops raining) and see how bad that is. It looks to me to be about a 3/4" sag, but I'll know more when I get the cover off. My tentative plan is to use 2 lengths of 1" box tube along the ceiling - running side to side - and attach those to brackets screwed into the side boards. I have seen some similar fixes in other posts for sagging roofs. If I can get the sag fixed, then I will proceed with the roof repair. That is where I am trying to learn more about the EPDM roofing... Thanks for the reply.
