I have never been a fan of the rubberized roofing on our Voltage. And now, after 10 years the roof needs some work and I'm considering an alternative type of material. I just don't know yet what "type" I'm going to use. Several years ago the back corner of the roof got a tear from a low hanging tree branch at a campground and I didn't do the best job of sealing it up. We ended up with a section of the roof decking needing to be replaced. I pealed back the EPDM and replaced the OSB (plywood), reglued the EPDM and put the correct patch material over the tear. All appeared to be fine after that.
Then two years ago I found a considerable soft spot under where the roof ladder is mounted. Apparently the DICOR type sealer around the mounts had leaked. I just cleaned the spot and applied more sealer to stop any additional leaking and damage. Now its time to get serious about fixing it and rather than just peal it back and repair the decking like I did on the other side I want to remove the entire ladder mount since we don't use it anyway. This means I need to patch the 4 mounting holes. So, instead I am considering pulling up and replacing the entire roof.
The question is replace it with what? I am not interested in paying a ridiculous amount of money to have someone else do the job. This will be a DIY project of which I am quite capable. I am intrigued by the direct roll-on or spray on roofing material that is available. The online videos and adds make it look easy enough and the roofs sure look good when they are done. But how well do they hold up and how long do they last? One of the materials I've looked at is Crazy Seal (https://crazyseal.com/rv-roofs/
). I like that this material can be applied directly over the wood roof deck of the RV as I would like to remove all of the EDPM and start clean.
Has any one replaced their roof with something other than EDPM or TPO rubber, preferably something that can go directly on the wood deck? If so, what product did you use and how has it worked so far?
