what is the best truss angle for attic trusses

[jsice78]

Im planning on building a polebarn in spring summer time and we get a lot of snow here. What is the best truss angle for a good size attic also its going to have 16 ft side walls

Welcome to the garage journal.

Do you have code height limitation or roof slope? What is your height for the first floor? Are you going to have a lift? Is the attic space going to be a mezzanine or separate floor? What are the spans? How are you planning on insulation? Have you read any reference material on the subject? What is your skill level?

I know people do it, but when I built my shop a number of years ago, two of the contractors I worked with in the planning stages said they wouldn't do a pole barn with attic trusses or storage trusses and I was only looking at 12' ceilings. Something about lack of wall stability with pole construction.

I ended up with stick framing and decided I couldn't afford attic trusses so I downgraded to storage trusses. Stick framing ended up being about the same cost.

Attic trusses are typically 12/12 pitch, so that's a pretty tall building with 16' walls.

It gets tall quick.. A lot will depend on your area codes for roof loading. I too went stick built after talking to the engineers that were working on the house we were building at the same time as the barn...
