Traditionally, roofs are built on-site wherein carpenters fixed plates and cut the rafters to the required length to build the structure. While this is an acceptable way of building, it’s quite more complex requiring human measurements.
Prefabricated roof trusses today are made to address the issue and make the building process much easier and faster. They can now be lifted and craned easily, as well as can be customized according to your specific requirements. This is how roof truss designs serve as the most simplified way of roofing. The design must follow the layout that has been prepared originally. Then the external load can be calculated which includes the load of the truss.
Generally, roofs that are wider and longer also require more trusses to cover up. For instance, the number of rafters needed to make shed roof truss design is usually twice the number of trusses required, which again, depends on the length of the roof.
This truss design is commonly found in houses. On the other hand, flat roof truss design is usually used in flat roof structures of warehouses, malls, and logistical parks. This truss design has spans of little high range, making it perfect for those buildings which are already at a higher level.
