I'm building a tiny house and it will have metal siding. My dad has worked a lot of construction and says he's never installed a house wrap for a metal building in his life. Most info I can find online says if it's climate controlled it needs wrapped. Just wondering how important it is when it comes to metal siding?
Also, I may cut it close when I get to the tops of the walls, I'm planning to use the rest of the #15 asphalt felt I used on the roof to finish the job if I run out so I don't have to buy another roll. Is this a good idea?
