Roof panel seam

[getastro]

Hello all, I decided to clean the roof on my trailer today. I have a 2012 V-lite 35' not sure of the model number at this time. I clean my roof about three times a year. Usually I have no problems, but today as I was scrubbing the roof I step back and heard a crack. I moved my foot and checked out the area. It looks like I stepped right next to a roof panel seam. Now in that area the panels have a little give to them. It did not affect the alpha system roof material. Should I be worried about this or just make sure the next time I clean my room to void all seems. Just checking to see if this ever has happened to anybody else and if so did you do anything about it
