Last fall I installed a new EPDM rubber roof. It seems like a great product for a flat roof like I have on my workshop but, it was the first time I have worked with it and there was a bit of a learning curve. If this is a project you plan on doing yourself, hopefully this video will point out a few things to watch out for while working with this material, and give you some better results than what I ended up with.
