Here are some pictures of the guys installing the epdm roofing. I think it was pretty easy - at least they didn't complain to much.
Rolling on the contact cement. Once you get 300 pounds of rubber on the roof, then you put the adhesive on both surfaces let it dry and then roll out the rubber. The got all of it installed in about 5 hours. We still need to install the drip edge and put the seam tape on but its weather tight.
