Hi everyone,
First time user here. Just wondering if I can get some advice on a roof for an existing decking.
I want to build a roof that will be quite separate from the existing decking. I will be putting in my own posts with a ledger attached to the house. Between the posts I will have a span of 7.2 metres and this is where I need some advice.
With such a large span is it best to use maybe a c channel purlin or a laminated beam maybe?
If I use a timber beam I imagine it would have to be approximately 300 x 65 or there a outs for such a large span. Then there is the weight of that.
Any advice would be appreciated cheers
