Hello...
I am currently swithering on whether to use proprietary attic roof trusses, i.e engineered attic trusses from truss manufacturer, or whether to go down the route of cutting and manufacturing the roof on-site without involvement of a truss manufacturer (though obviously with Structural engineer to spec. timber sizes, nailing/bolting guide, etc).
The Structural Engineer has informally suggested using Truss Manufacturer, sighting timber sizes as a key issue in this choice (i.e. truss manufacturer will be able to specify smaller timbers than the engineer).
Does anyone have any thoughts on this? For example, timber sizes (big difference?), cost, difficulty!!!?. Is a manufactured attic truss a better option? Is there a greater risk of a sagging roof if cut and built on site?
If seeing the design would help some drawings can be found at:

Any answers, views, directions to companies or websites would be welcome.
Jamie.
p.s. house to be built is in Argyll, Scotland (Central Scotland!)
