Ok so I have had 3 quotes thus far and all are beyond our budget, some options include ordering Stratco materials (also not terribly cheap) and DIY or ordering custom timber materials and DIY. We have an older weatherboard (c 1890) which we have recently added an extension too and it would be nice to continue the aesthetics from the Edwardian era using timber. Seeking to do a gable style roof (colourbond), 2.4m ascending to approx. 3.0m with a 22.5 degree fall. I would like to think with enough Youtube videos, asking around etc that I could do this myself but I am reluctant to take the plunge until I have investigated this more thoroughly. There is an old structure in place which we seek to knock down and a concrete slab will remain. It would be great to receive advice or tips; things we should be wary of, places to go for technical advice.
