Hi,
Soon I am going to build a shed 4.2 by 2.4 mtrs.
I am planning to include an intensive green roof which when wet weighs about 18llbs per square foot.
which If I have calculated it correctly is a total weight of 881kg
I am planning to use 2"x4" at 16" centres, for the whole structure. Is that sufficient or will I need larger joists for the roof or shall I reduce the spacing?
Thanks for your help
