How far can 2×4 trusses span?

A 2×4 can span a maximum of 6′ 7” when spaced 16” apart and used as a floor or deck joist. When used as a ceiling joist or a roof rafter, a 2×4 can span up to 7′ 3” spaced at 16”, and 6′ 4” when spaced 24” apart. Due to the small spans of 2x4s, they often are not used in horizontal load-bearing capacities.

What should roof trusses be made of?

The best material for building trusses on a small scale project is sawn lumber. Dimension lumber and engineered woods like plywood are not available in the sizes and lengths necessary to build a solid truss. The roof truss will have a horizontal lower chord, and 2 angled upper chords that follow the roof line.

What type of wood is used for roof trusses?

Answer: Yes, species combinations like Hem-Fir and Spruce-Pine-Fir are used regularly in truss manufacturing as well as Southern Yellow Pine and, as you mention, Doug Fir-Larch.

How much load can 2×4 take?

A 2×4 can hold up to 40 pounds or 300 pounds when laying on its edge without sagging when laying horizontally. Several factors can lower or increase a 2x4s strength, including wood species, lumber grade, and moisture content.

What is a good slope for a shed roof?

You would not use a lean-to for a very steep pitched roof because it would require you to build the wall on one side of your storage shed to a significant height. Gambrel roofs are made up of four rafters, two on each side. Each one is cut at a 45-degree angle, creating four faces of the same pitch.
