What Is The Maximum Span For Roof Trusses?

A wooden roof truss can span up to 40 feets without support, but the distance would be impracticable and prohibitively expensive in any dwelling. Trusses are intended to span areas without interior supports, and spans of up to 40′ are common in modern dwellings.

Generally, Standard trusses can be designed up to 11 metres in 35mm timber, and 15 metres in 47mm timber. 

It is more practical and less expensive to rely on other methods, such as structural insulated panels (SIPs) or sheathing, or to use some combination of the above.

There are a variety of different types of roof trusses, and each type has its own maximum span. For example, the maximum span for a typical steel roof truss is about 80 feet, while the maximum span for a wooden roof truss is about 40 feet.
