Class A TPO Roof Replacement

DIY TPO Roof Replacement on a Class A Motorhome

~100% done by amateurs who shouldn't be doing this but did and lived to tell the tale ~

This is the largest DIY project I have ever attempted in my life. We recently bought a class A motorhome (a 2013 Coachmen Pursuit 33BH)  for a great price that had soft spots on the roof so we knew it needed a new roof. However, we did not like the $8,000 quote we received to install a new one so after doing some research we decided to do it ourselves. 

Now that we have successfully completed the roof installation, let me tell you one thing: those technicians deserve every last cent of what they ask. The amount of literal blood, sweat, and tears that we put into this project is enough to float a boat. It is physically demanding, but if you are up for a good challenge you can do it yourself with a bit of planning and a lot of manual labor. It took my husband and I about a month to complete, working on it when the weather permitted on the weekends. In the end, I am so incredibly proud of the result- we not only replaced the roof but ENHANCED it. The roof survived not one but TWO tornado warnings (with touchdown not too far from the house)and weeks or torrential rain, wind, and spectacular lightning storms.

There were so many things we discovered while taking it apart that were not done correctly by the factory and I could be mistaken but I am sure those things would not have been corrected had we hired someone to replace the roof, as it required a substantial amount of additional effort. I have decided to break this project into several pages, as it really helped to conquer each task one by one. By no means are we professionals, but we have done so much research and feel that we have completed this to the best that we could do without a professional shop. I hope you enjoy this post, and good luck on your project!
