Weights And Terminology Of Trusses

Question: 

How do I go about estimating the weight of a roof truss framing system? Is there a table of span vs. pitch vs. weight of trusses? Is there a guide available that shows how the components of various roof styles (hip, gable, etc.) are commonly framed and the associated terminology?

Answer: 

Depending on the size of the members (top chords, bottom chords, webs) there is a corresponding weight per linear foot. You can use this chart to help with that calculation. Multiplying this number by your total span should give you a rough estimate of the weight of the trusses themselves. Another resource you might be interested in is SBCA’s TTB – Truss Configurations, which covers basic truss terminology and shapes.
