Exterior Roof
The owners manual (2021 MLE) states I have a "Superflex Roof". After some research I believe it is the same as "TPO". Please correct me if I'm wrong. In any event, I have noticed that the skin for lack of better words is "puffed up" and loose around the roof edge in several spots. So, I did some research and found an old post on here that stated that should not happen. Further stating that it eventually caused damage and Grand Design replaced roof. Any help. Thanks.

Thank you, I have. I sent dealership and Grand Design letters via us mail. NO response. I drove to dealership and sent Grand Design letter via certified mail. Inspection is scheduled in August.

Our Solitude 5er looks to have a bubble under it the entire length, all 38 feet of roof line, on the sides and most of the way across the front and back. And various bubbles about 6in to a foot around on the flat part of the roof. I sent pictures to the dealership and they said it was normal. Then I sent them to Grand Design and they said normal. 2,500 miles later and 4 months into a 12 month road trip the front of the TPO roof started peeling off. Grand Design is covering it under warranty when we got back, it's been at the dealership now for 6 months, they weren't to happy with me for using flex tape to hold it together, but I could not find the correct roof tape. I just wonder how much snow and rain got under it.

It pulled out from under the front cap. It looked like the bubbles at the edge of the cap and seam tape rippled in the wind while driving and eventually pulled the roofing material out from underneath the cap and tape.

I have a good friend that used to own a RV dealership (he sold it a few years ago). He is convinced that a lot of the problem with roofs bubbling up are from air getting in through the front cap at the pin box and then forcing its way out at the roofline under the rubber. Not sure if he's right but I pulled the lower shelving unit out of my front closet and stuffed the gap between the floor and the cap with insulation. With my phone I was able to see daylight under the floor from the pin box area. So air could get in, just a matter of how much pressure there is with all the turbulent air under there while traveling down the road.
Can't hurt and its insulated better now anyway.2021 Solitude 375 RES-R
