What is this under my epdm roof????
3 year old primetime camper. i was doing roof inspection today and i noticed a spot about one inch by one inch that felt like putty or sealant underneath the rubber roof..it was squishy like extra sea...

im sure its plywood..but what would that lone bubble be? it feels like playdough or putty under that little tiny 1x1 inch spot... im sure its nothing to lose sleep over... i wonder if it could be the glue that built up a bit there..
