How far can a roof truss span?

Trusses can span up to approximately 90', although very long truss spans are more challenging to deliver, erect, brace and install properly.

How far apart do roof trusses need to be?

The trusses should be a little longer than the exact width to allow for overhang, and you will need sufficient trusses to mount across the length. Most are spaced between 18-26 inches apart. Once you've calculated the number of trusses you will need, you should purchase the lumber.

How do I build an attic truss?

In order to create an attic truss , certain conditions must be met in the plan:

The structure must be wide enough and the roof steep enough to allow space for a loft area with attic rooms on either side of it.
The loft area cannot be on Floor 0 or Floor 1 - it must have a living space below it that has a flat ceiling.

Can you cut the bottom chord of a truss?

If that solution is not acceptable, it might be possible to cut out the bottom chord of the truss and add collar ties. The first problem is that the bottom chord of most gable trusses bears on the wall, with the top chord meeting the top edge of the bottom chord just above the bearing point on the wall.

Are trusses load bearing?

Trusses, unless a special girder truss (which accepts the loads of attached trusses), have no interior load bearing walls. That is the beauty of trusses! Technically, the interior (partition walls) shouldn't even be touching the truss bottom cord during rough-in, but they usually are.

Which is stronger rafters or trusses?

It is certainly true that trusses are more commonly used than rafters. They're more economical to build and offer the same or greater roof strength. There's a lot to like. However trusses don't give you the opportunity for creativity in home design that rafters allow.

Due to the triangular shape of all but flat roofs, the rafters or joists will run perpendicular to the roof ridge as well as to load-bearing walls.

Should I use 2x4 or 2x6 for roof?

As small as it is 2x4 on 16 centers would be fine. Use a 2x6 for the ridge. If you plan to tie the roof together, 2x4's would work.

Do rafters need collar ties?

Rafter ties (or ceiling joists acting as rafter ties) are required by code unless the house is designed so that the walls or a structural ridge beam carries the full load of the roof. Installed in the top third of the roof structure, collar ties prevent separation of the roof at the ridge due to wind uplift.

Do trusses need support?

Determining whether you need central support for a roof truss ultimately comes down to why you need roof trusses. Generally, you don't need central support for domestic trusses. In industrial applications, trusses support enormous roofs made from heavy materials and thus generally require central support.
