Hello friends! I’m almost done gathering supplies, I’m starting reno when the weather decides to be kind for more than two days lol. That said, I am opting for “5mm wood underlayment” panels for my walls. So out of curiosity, I want to safely walk in my roof for solar panel access. Is the framing and aluminum skin enough to support my weight up there? Do people put wood sheets up there for stability sake? This would add a lot of weight and potentially inhibit proper fitting of my siding. What are you opinions? Thank you all for the help!!
