Bugs under metal roof
I am building a shop right now and plan to put an exposed-fastener metal roof on it. The attic is open, and the insulation will be between the rafters. I’m about to install a metal roof. My plan is to install it over cross battens to keep the steel ventilated and reduce heat inside the building.
I am having a difficult time deciding on what to do about ventilating the eaves. I know that in a rainscreen wall application, screening the bottom is important to keep out insects like wasps. I am wondering if this is necessary with a roof which, on a sunny day, likely exceeds 40-50 degrees. I may get some bugs up there now and then but this seems too hostile an environment to encourage a serious pest problem(?) Perhaps this is a question best posed to an entomologist, but I would appreciate any input.
