Workshop Roof?

[PawsOfEvil]

Hi

I am currently building a workshop at the end of my garden. The frame size will be 5.8m x 2.6m when complete. The tops of the wallboards are all nice and level - now comes the snag.

I am hoping to build dual pitch roof with gable ends. Ideally the apex should be offset ( for aesthetic reasons) so that from the front you can see a smaller section of roof with the larger trailing away to the rear.

I would like to use felt shingles to cover it with. Roofing info is a bit hard to find on the net.
I was planning on building 5 simple triangular roof truss' with one vertical support on each, those can sit on the wallboards and would be tied together with a ridge board. Whole thing covered in OSB/felt underlay/shingles.

Question is - is this design suitable for the span of the roof? Does the ridgeboard have to be one continuous piece? If so practically how do I support the ridgeboard whilst constructing the trusses?

It would be easier making it a trussed roof.

Sorry if I didnt make it very clear, but that is what I am intending on doing. The link you posted shows an apex truss that is equal on both sides with a 'W' shaped 3 beam support. Im wondering if I can get away with building a lower sloped roof with only the central support.

Yes it is feasible.

The longer shallower span may need stronger section timbers than the shorter steeper one.

You may also create an overhang anomaly due to the differing pitches. This anomaly will be largely aesthetic rather than structural.
