**truss**: The

**truss**is 24-0-0 in length and 4-0-0 tall. Multiply the Span by the Heightto

**calculate**the area: 24ft x 4ft = 96 sq-ft. area. Multiplythat by the

**weight**of our material (2psf), and we get atotal

**weight**of 192 lbs.

Correspondingly, how much does a roof truss weigh?

For wood **trusses** with a total load of around 180pounds per lineal foot (30 pounds per square foot spaced one at sixfoot or two at 12 feet), a single 24 foot span 4/12 slope **trussweight should** be about 125 pounds.

**trusses**loaded by downward forces, the members alongthe top (the “top chord”) are in compression and themembers along the bottom (the “bottom chord”) are intension.

**Laws of statics**

- are equal in magnitude;
- are opposite in direction; and.
- act along the line between the two points.

Furthermore, how do you calculate roof trusses?

Divide the length of the **roof** by two to**determine** how many **trusses** are needed. **Trusses**are generally secured 24 inches on center along the top plate. Fora 30-foot long **roof**, a total of 15 **trusses** areneeded.

For a 2,000 square foot home, **roof truss**installation typically **costs** between $7,200 and $12,000.You'll spend anywhere from $1.50 to $4.50 per square foot formaterials alone, or between $35 and $150, though extremely long andcomplex types can reach $400 each. Labor runs anywhere from $20 to$75 per hour.
