It's the trusses, they are tall, which makes them very stableHow do you get away with such wide spans and no support for the roof?
any insulation in the Walls?
It's a pole barn. Least that's what they call them. So the roof is trussed.How do you get away with such wide spans and no support for the roof?

They have 2x6's that connect the trusses together then the metal roof goes on top of that. Not much snow has even stayed on the roof, seems to slide off really easy.Trussed or not, it just looks like a long ways between trusses to support snow loads
Trusses themselves look doubled and STOUT.
Just odd seeing that much area between them.
As I was putting it on ....I bet it dried fast at least.
Different type of building Dave. Mine is a pole barn. I am guessing that they build then nation wide, well somebody does.Those trusses would never make code in MI.
Mine are 36’ span, 2x6 bottom cord, 6/12 pitch, 2’ on centers, with 2x4 stringers every 2’ going up to the peak.

Yup. The major cities around here are at about 4000', but being a desert, we rarely get more than 1' of snow that lasts for any length of time. Plus, our snow is extremely dry. Makes for the best skiing around.Less snow load

It's a different design, both work and I don't believe the code anywhere specifies the spans, the structural engineer does and he is responsible for it. Your posts and trusses are massive multiple layers and the runners horizontally are resting on them.
