What is the purpose of using trusses in a double-pitched roof?

Using trusses in a double-pitched roof primarily serves to support the roof structure. Trusses are engineered frameworks that distribute the weight of the roof, helping to manage the loads imposed by wind, snow, and the weight of the roofing materials themselves. This structural support is crucial for maintaining the integrity and safety of the building, ensuring that the roof can withstand various stresses over its lifespan.

While trusses might contribute to aesthetic features, their primary function is structural. They allow for larger spans without the need for additional internal support, creating open spaces inside buildings. Additionally, when designed properly, trusses can also help reduce overall material usage by optimizing the structural design, contributing indirectly to cost efficiencies, but the main purpose remains the support of the roof structure itself.
