I have acquired a roof ladder that I intend to install on a metal roof. I've read a bit around but I'm not quite sure about the rules. Sure, I could call and inquire, but I just thought I'd check here if someone has a clear understanding of the rules for roof ladders, fastening, etc. The house is from '75. The roof has a slope of 5 m. Is it enough if you lay the ladder over the ridge and screw it in there, as well as attach it down by the eaves? Anything else to consider when mounting a ladder?
Grateful for tips and opinions.
