What distance should roof trusses be apart?
The number of trusses required for a roof depends completely on the design. However, typical roof truss spacing means that they are usually 400mm (16 inches) or 600mm (24 inches) from centre – this means from the centre of one truss to the centre or the next truss.

How much weight can ceiling beams support?
Regular garage ceiling joists of modern construction can generally support 50lb/sqft. If you have trusses or your joists are supporting more than just sheetrock or your garage is older this number could be significantly less. Remember to spread the load ACROSS your joists and not along them.
How far can a roof truss span without support?
How far can a double 2×10 span without support? When supporting joists that span 12 feet with no overhang beyond the beam, a double ply beam can span in feet a value equal to its depth in inches. A double 2×12 beam can span 12 feet; a (2) 2×10 can span 10 feet and so on.
What is the maximum span for roof trusses?
Light trusses, such as trussed rafters of 2 to 4 ft spacing, are recommended for spans up to about 50ft (see Fig3. 8). They can be built for longa spans, but a heavy truss with larger spacing may be more economical for this purpose and may even be so for spans under 50 ft.
