Movement of underboard on EDPM roof
Maybe this is a common thing I don't need to worry about, but on one of the "seams" (from one side to the other) underneath my rubber roof, it feels like one of the boards (or whatever is under there)...

Roof material and rib space will vary by manufacturer and even model. Carriage used 5/8" structer board and ribs were on 16" centers. You need to check with your builder, or maybe brand forum.
