    Roofers advice please:

    Doing my garage / man cave...

    Want to run the joists for the roof length ways which is 5.45m length

    Gonna be doing Osb board and EPDM roof

    Would you go for 6 x 2 or 8 x 2 and 400 / 600 centres?

    Also would you buy 6m lengths or would you buy 2 3.6m and strap them or would you run a timber width ways with wall straps and hang them length ways off that

    Thanks for your help, my original plan was 6 x 2 in 3.6m lengths and bolt together but happy to go with any advice given

    I think a 9x2 will give you a max span of 5.1M using C16 and 400CC

    So 6 x2 would be a bit bendy!

    you could do them in 2 lengths but would then need a support beam midway, either a triple bolted together, glulam beam or steel (you havent given the size the other way)
