Types of Roof Trusses:

Residential: Wood roof trusses can be used in most any application. When new homes or additions are constructed trusses are primarily placed 24″ O.C. (on center spacing) even 16″ O.C. is a common practice. The loads used in residential trusses consist of 1.Live/Snow Load 2.Top Chord Dead Load 3.Bottom Chord Dead Load. Typical loading for stark county,Ohio/Canton, Ohio area would be 25-10-10. Further north such as Cleveland, Ohio Live/Snow loads would start to increase from 25psf up to 40psf. Always be sure to contact your local building department and find the correct snow loading for your area.

Agricultural: Wood roof trusses are also great for agricultural buildings. Trusses can span up to 80′ without any center supports. This is called clearspan. Another great feature of agricultural trusses is the ability to space trusses 4′ O.C.. Carpenters can then run 2×4′s horizontally on top of the trusses to fasten either plywood or metal roofing. Mono trusses are also very popular in the agricultural world. Mono trusses can be placed against an existing building to expand the structure. This is great for extra machinery storage, or hay storage. When spacing trusses further apart, this means less trusses which in the long run is money in your pocket.

Commercial: Wood trusses are also very popular with apartment buildings, and all types of commercial buildings. Usually in this application blueprints must be stamped by a licensed engineer. This of course also means wood truss drawings would also need a engineers stamp. Wood roof trusses used in a commercial application require much more attention to detail.
