I just thought I would let everyone know that I have a friend who has a 34' RV that needs a total roof replacement. I am in the process of ordering the materials for him. I am also going to help them tear off the old roof and install a new white on black EDPM rubber roofing membrane. I will make post about the materials I use and how hard or easy the installation process is. An estimate of $2,650 was given to hire a dealer put on a new roof on this RV. I have found the materials on line for about $500 plus shipping. I will try to keep up with all of the cost and time involved with this project and report it. I hope this information will help some of you decide if you can do this install yourself and if it will save you much money.
