How thick should roof trusses be?
We usually opt for the 35mm thickness in timber when designing standard timber roof trusses. This could be for Fink Trusses in a house construction or Queenpost trusses for a garage. Meanwhile, the 46mm thickness option is used for attic trusses due to fire regulation guidelines.
Are roof trusses 2×4 or 2×6?
Trusses only use 2×4 lumber and are constructed using a “web” of 2x4s for strength. Rafters simply rely on a center ridge beam and the outside walls for support. While there are benefits to both, only rafters vary in the size of lumber that is used.
What determines the spacing between trusses?
Trusses are usually spaced at regular intervals, typically 600 mm, 900 mm or 1,200 mm apart. The spacing depends on the mass of the roofing material and local practice. A range of truss types can be configured to attain different shapes.
Can I use 2×4 for roof rafters?

Whats the difference between a rafter and a truss?
Rafters and trusses are those that support the roof. Though both rafters and trusses are triangles in shape, the trusses have more triangle webs inside the principle frame. Rafters consist of sloping outer beams which provide support.
Are trusses stronger than rafters?
Are Roof Trusses Stronger Than Rafters? Yes, roof trusses can hold a great deal more weight than the rafters. Not only that, but they can also span a longer distance and still hold more weight.
How thick should Plywood be for a shed roof?
Plywood thicknesses for roofs start at 3/8” in areas with light load requirements on rafters at 16” centers. Thicknesses of 1/2 to 5/8 inch are common with rafters spaced at 24” centers. For heavy load rated areas, 3/4-inch-thick plywood is recommended, regardless of rafter spacing.
