Roof problem on a sprinter 311bhs

[hotrodjim5054]

Hello,
I have a 2011 sprinter 311bhs that I have had a few problems with over the last 2 years besides the outdoor kitchen door shocks coming out from the door all the rest have been minor. Last week when I was up on the roof for its spring cleaning I noticed a large bubble in the center of the roof. Its about 2 1/2 feet from the front about 3 feet from the sides. Its hard but not smooth. Does anyone know what this may be? thanks for the help

I can not picture what you describe ... maybe a photo might help.

Thanks for the reply. I did take a bunch of pics but you cant really see anything. it is about 2-3 feet around and feels like either plywood pattern or wires underneath

Unless they were there at manufacture time ... I can't see how wires or construction debris could get between the rubber material and the roof decking. Sometimes it is not done too well, but the rubber is glued down. Is this the first time you have been on the roof?????? Or is this something that has just developed?????? :confused: Hank
