Truss framing systems, and the names associated
with them, vary all over the country and
throughout the world. No matter how they are
framed or what they are called, though, truss
systems easily provide tremendous flexibility in the
look of the roof system.
The illustrations below are designed to help you
visualize typical framing systems, looking at:
• A truss placement plan,
• The overall 3D look of the roof planes in that
roof system, and
• 3D view of the framing system of trusses.

The most basic (and least expensive) of roofs, a
gable roof rises vertically on the shorter ends of
the building, with sloping planes on either side,
which meet in the middle. In our example you'll
find a gable frame on either end, each supported
by the continuous wall underneath it, and common
trusses in between, each of which spans from one
wall to the other.
