Pretty easy. You lay a 4 x 8 sheet of plywood that forms the roof sheathing on top of the truss. Then you pop, pop, pop, pop, pop across the plywood where you THINK the truss is but get it off by an inch or so. The nails either split through the edge or just miss altogether. There is no tactical feedback like when you are driving a nail with a hammer. There is a slight change in the pop noise and you should notice the head of the nail sinks deeper but most contractors seem to be more interested in speed than quality.
The same thing happens putting sheathing on the side of a house. This is from my Tuff Shed. Notice the 6 nails that missed the mark? That panel was built in a factory so their is zero excuse for this shoddy work.
