It is always frosted over on the roof when I open it up to fish... and then runs and drips constantly when I run the heater...
I have a big roll of black rubber tarp for building that was left over from our garage. I also have more blue foam board, do you think if I staple some of the black rubber tarp to the top and then place my foam board up in the roof and spray foam around the corners to hold it in place it will stop the dripping??
