    Your thoughts please

    Provided suitable packing and longer fixings are used, will fixings on the ridges of box profile sheet (instead of the recommended valleys) cause problems ?

    Reason for asking – I want a detached garage roof slope to be less than the recommended minimum for box profile sheets. So I plan to use extra lap sealing and fixings on ridges to reduce water ingress from any ponding or ice dams.

    Thanks

    I have bought those sheets in 7m long so no need for joins unless you have a huge garage. The only problem I can see if you fix in the top is can you get them tight enough to self seal before they deform the metal!

    Yes this is the reason for using packing. I was just trying to think of any other potential issues. For instance - is max wind uplift load reduced ?
