Types of wood roof trusses.

This particular truss is made out of wood most of the time but it can also be built out of a combination of steel and wood. As the name implies this roof appears flat in structure although it is always pitched at a wider angle to allow water runoff. Alpine truss designs are engineered to meet specific span configuration and load conditions. The king post truss is mainly adopted for short spans less than 6 m.

Below are the common types of roof. Total load psf duration factor live load psf roof type 55 1 15 40 snow shingle 55 1 15 30 snow tile 47 30 snow 40 20 snow 1 25 20. This method allows for greater energy efficiency. There are two fundamental types of trusses i e.
