Metal roof may be leaking
I have 2 climate controlled metal storage buildings and am seeing some moisture on the vinyl faced insulation on one of the outside walls. I have only seen this in a couple of places but have not located any leaks, but then the vinyl faced insulation against the roof makes it hard to find. When I felt up behind the gutters, I discovered that the foam rubber used to fill the gaps at the end of the steel roofing is missing in some places and the insulation was wet. The building is only 3 years old. I am considering a roof coating unless someone can give me a better (hopefully cheaper) solution. Thanks in advance for any help.
