The cost of timber roof trusses can vary significantly, depending on various factors, such as the roof pitch, roof shape, roof cover type, pre-fabricated trusses, exposed bolted trusses, and ridge-beam rafter design.
When it comes to the estimated cost of roof trusses per square meter, excluding the roof covering, it can range from R250 to R650 or more. However, the most cost-effective roofing solution, including roof cover and installation, is typically a cement-tiled roof with a 20 to 25 degree roof pitch. It is important to note that this cost may vary by region.
If we only consider the cost of roof trusses, excluding the roof cover, a metal sheeting roof structure is usually cheaper due to its reduced number of trusses. However, the cost of sheeting is more expensive than cement tiles, which gives cement-tiled roofs the advantage. Furthermore, the labor cost for installing a cement-tiled roof is generally R10/m2 less than a metal sheeting roof.
If cost is not a concern, there are numerous options available, including creative roof designs. Metal roof sheeting is a preferred choice for raised-tie beam trusses with a raised ceiling as it is lighter than cement tiles and allows for higher tie-beam and ceiling levels. The lightweight nature of metal roof sheeting also makes it ideal for ridge-beam and rafter designs, as it reduces the load transferred from the rafters to the ridge-beam.
Apart from cost, there are other factors to consider when choosing roof trusses, such as durability, strength, and design. Timber roof trusses offer excellent durability and strength, making them a popular choice for various roof designs. They are also versatile, allowing for creative roof designs and shapes.
