🤔 What Are Roof Trusses?
Before we get into the various types, let’s first understand what roofing materials like roof trusses are. Essentially, a roof truss is a structural framework of beams that supports the roof. The design allows for distributing the weight of the roof evenly, providing stability and support.
Why Are Roof Trusses Important?
Roof trusses are crucial for several reasons:
- Structural Integrity: They provide essential support to the roof, ensuring it remains stable and secure.
- Cost-Effective: Pre-fabricated trusses are generally more affordable and quicker to install than traditional rafters.
- Versatility: They can be designed to fit a variety of roof shapes and styles.
