Wisconsin | I have done a fair number of these barns. I would put strips on top of existing roof 1x4s. I would even consider them over the plywood if you tear off. Your screws have more to grip into. And nothing rubbing on the steel like a loose nail. Sometimes on tall steep jobs we go for 2x4 strips just because they are easier to walk on and not too much more. Also rent a telehandler and a work platform. It will make the job so much easier and safer. | |
