This online truss calculator will determine the all in cost of your truss based on key inputs related to the pitch width and overhang of your roof.

Trusses can be constructed with smaller sized lumber than rafters and often their cost is not significantly higher than normal rafters.
Determine roof truss spacing.

If you live in an area where you get absolutely tons of snow and have a low pitched roof on your shed then go ahead and put them 16 on center.
Use of manufactured roof trusses can dramatically cut labor costs when framing a gable roof compared to building rafters.
To determine how many trusses to create you will first need to measure both the width and the length of the structure you are building.
Standard roof truss spacing.

On older mobile homes where the roofs are nothing more than a covering of thin sheet metal the lines of the support beams are clearly visible through the metal.
The typical standard for the spacing on the roof trusses is 24 inches.
Typical roof truss.
24 on center is fine for shed trusses.
The roof truss spacing standard is important because eighty percent of new homes are built with standard pre fabricated trusses.
Spacing a live load deflection limited to l 240 maximum and use lumber properties as follows.
A mono truss roof allows for more sunlight and visual space proper drainage and relatively cheaper.
However most homes use pre fabricated engineered trusses designed for 24 on center.
Spaced sheathing or 1x boards may be reduced slightly.
Allowable spans for 2x4 top chord trusses using sheathing other than plywood e g.
This means that if you re in charge of repairing or installing roofing trusses you ll be expected to hold to these standards.
Common spacing for trusses on this type of building is often between 2 and 4 feet but trusses built with advanced designs may allow spacing as great as 8 or 12 feet.
