Hi just a little feedback. the trusses seem fine and we have had a considerable amount of wind alto the snow has been light less than a foot at one time. I made a mistake using the suntuf panels and when building the tractor shed with the medal roof was able to use clear roofing panels supplied by my metal roof supplier. Those panels were much easier to install and less than 1/2 the price and they look as good or better. There is a leak in the suntuf roof that I have so far been unable to locate but the panels have multiple gaps so this spring I will silicone the gaps. the metal roofing supplied panels have no gaps. live and learn.
