What Size Roof Trusses Do I Need. A gable truss sits on the end wall of a house or garage and has vertical studs every 2 foot or 16 inches for nailing the sheeting too. In industrial applications, trusses support enormous roofs made from heavy materials and thus generally require central support.
So you will need more trusses for 16� spacing which will likely mean higher costs. This is $2,400 plus the cost of the plywood subfloor. You can if you wish but generally this is just over doing things and wasting you more money.

Most interior beams need to include the roof load. It has been my experience to never use a beam smaller than a two ply 2 x 8. A gable truss sits on the end wall of a house or garage and has vertical studs every 2 foot or 16 inches for nailing the sheeting too. Divide the length of the roof by two to determine how many trusses are needed.
