Most Efficient Roof Truss Design Science

When it comes to roof trusses you need to consider everything from design to cost to the pros of using trusses instead of stick framing a roof.

Most efficient roof truss design science. Understanding roof pitch is both fairly basic and a little complex. The chord size and web configuration are determined by span load and spacing. Bowstring pitched and flat. Some common trusses are named according to their web configuration such as the king post fan fink or howe truss.
