Hi, I'm new here and would really appreciate some advice. My DH is currently building a new garden shed with a woodshed lean-to on the north side and a coop on the south. The coop will be 8X10 and DH is using rough cut lumber, but will be insulating just the walls in the coop part. We are debating what kind of roof to put on the whole project. We like the look of metal, but I was wondering how a metal roof would affect the temperatures inside the coop. Is it warmer in summer and colder in winter? Or does it not make a difference. Thanks!
