How are truss roofs constructed?

Roof trusses are also incredibly versatile. They can be used on any scale of building from small sheds to auditoriums.
What is a disadvantage of a typical roof constructed with roof trusses?
The biggest downside to roof trusses is that many types of trusses do not leave much space for a usable attic. There are certain designs that will create a small space, but this space is often half the span of the truss. Roof trusses, on the other hand, can be customized but are often limited to less complex designs.

Most exterior walls are load bearing, but not all. It all comes down to where the roof trusses/rafters and floor joists/trusses are bearing. Long skinny homes may only have two exterior load bearing walls.
What type of truss is strongest?
I think the warren-truss design will be the strongest because it is the simplest design and spreads the weight of the load evenly over the bridge.

Are trusses better than rafters?
Once in place, rafters use up more wood, so they weigh more, but trusses are stronger because they are more efficient and have the capacity to produce maximum strength using fewer materials in the end.
