Hi Guys
I am building a garden room in timber and wanted to ask what size timbers I need to use for the roof. The span it will need to cross is 4 metres, the actual size is 4m x 7m, the monopitch of the roof will be 4 degrees. Will using smaller spacing mean I can use slightly smaller sizes or is this irrelevant. I intended to use 400mm spacing. I had planned on using 145x 47mm but recognise that this is not going to be good big enough, the roof covering will be cladco box profile. As always any advice greatly appreciated and I hope my wording makes sense.
Thanks
