What are Roof Trusses?
A timber roof truss is a structural framework of timbers designed to bridge the space above a room and to provide support for a roof. Trusses usually occur at regular intervals, linked by longitudinal timbers such as purlins. The space between each truss is known as a bay.
Trusses cost between R 641.97 and R 7336.83 each in most cases. Complex or extensive roofs typically need specialized and higher-priced trusses.
Is it cheaper to build or buy roof trusses?
Roof trusses are built in volume, allowing truss manufacturers to take advantage of bulk discounts on raw materials. Contractors often cannot access these types of discounts, making it more cost-effective to buy pre-made trusses.
How do you estimate a truss?
How do I calculate roof trusses? The simplest form of this equation is to take the length of your roof and divide it by 2. For example, if your roof is 40 feet long, it will need a total of 20 trusses.
How far should roof trusses be apart?
Roof trusses should be 24” apart, on center. Trusses are allowed to be closer together, at either 12” or 16” on center, but building codes allow for 24” on center spacing without using heavier duty fasteners for truss-to-wall connections.
