Finally found some free used EPDM rubber roofing. It's in Toledo Ohio, I picked up two pieces and it almost filled my trunk in my car. I have no idea how much I'll end up with, hopfully enough to cover all my stacks. As the add says its dirty and muddy, but I didnt care. They have a lot of it if any of you Ohio guys are interested. If you had a pickup you could get a bunch. http://toledo.craigslist.org/zip/4789928412.html
As you know, I'm experienced in using that stuff and I gotta tell ya, it's the cats azz for covering your stacks. Good find! Get us some pics when you put it to use!
Did a job on a multi-plex theatre back in 99 and ended up with also a butt load of the stuff. Heavier than all get out because of the length of some of the pieces, but man is it nice! Could've made a big slip and slide out of it at the lake!
Ya gotta bundle your trips. The roofing lasts long time. Figure on buying something else to make it worthwhile?
