shed roof advice

[the1]

hi, quick question, if i use 2x4 which are 5mts long for my shed roof, can i use mini joist hangers to attach them? i will be using 18mm osb3 sheets on top covered in felt(flat roof). ive purchased 47mm x 67mm mini joist hangers from toolstation but they were unable to give any advice and i dont want the weight of the osb to make them give way overtime. thanks

4x2 about 2.4m -3m 3.6max i would say you need to do the maths

what is the length and the width of this shed? You may need an intermediate beam.

You'll have a very bent roof. Personally, I'd put in 3 A frames. You may just be ok with just one central one.

 

[JohnD]

how do you fit A frames in a flat-roofed shed?

Missed that. Hefty intermediate then.
