What type of truss is predominantly used for roof construction?

Pitched trusses are predominantly used for roof construction due to their design and functionality. These trusses feature a sloped configuration that allows for effective rain and snow drainage, which is particularly important in areas with heavy precipitation. The angled design of pitched trusses also creates additional attic space, which can be utilized for storage or even finished living areas, maximizing the overall utility of the building.

Moreover, the structure of pitched trusses enables them to distribute weight evenly across the building's framework, minimizing the risk of structural failure. This balance of performance, aesthetic appeal, and practical application makes pitched trusses a popular choice among builders and architects for residential roofs. The other truss types, while useful in specific circumstances, do not match the versatility and advantages offered by pitched trusses in standard roof construction.
