Is there a warranty? What's required for assembly tools, equipment, etc.? Is the roof a different material than the sidewalls? What is the snow load?
The warranty and tools required needed are both outlined in the manual on this product page. The material will be the same for the top and the sides. Additionally, there is no snow load rating for this unit. It must be cleared of any snow accumulation to avoid overload.
What is the width of the door at the rollup top of this garage?
