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)...

On a previous trailer I had a similar problem. One of the roof boards had come loose at a seam in the roof deck and it was sticking up above the adjacent board. I got some special roofing nails or screws with a "rubber washer" on them, then secured the deck through rubber roof to joist. It was about a 18" long section. Covered screws with Dicor and never had a problem with boards coming loose again, or a leak. You do not need very long screws as most rood decks or about 1/4 or 3/8 inch thick.
