need advice on pole barn venting
I have a 24X48 pole barn, metal sides and roof, on a concrete slab. The issue is primarily heat build up in summer as it's built pretty tight, secondarily, rusting tools. I've noticed there are various vents available including what I'll call the "turbine" or wind powered units. It would seem that the turbine units would want to be mounted horizontally and not flat on the sloping roof. We do have very windy conditions, coupled with rain, so leaking is a concern. I suppose I could buy or fab up something to come out just under the roof peak (front or back) which would allow horizontal mounting. Think of a wood stove pipe going through a wall and then going vertical.
Thoughts or opinions welcome,
