What are the lateral sides of a roof that hold the structure above referred to?

The lateral sides of a roof that hold the structure above are referred to as rafters. Rafters are sloped structural members that support the roof coverings and transfer the load from the roof down to the walls or beams of the building. They are typically made of wood or metal and are essential in creating the framework of the roof, providing both stability and shape.

Rafters are part of the roof framing and are positioned in pairs or in a series to create a triangular framework, which helps to evenly distribute the weight of the roof. This design is not only practical but also allows for effective drainage of rainwater, which is critical in preventing water accumulation and potential damage.

Understanding the role of rafters is crucial for any construction-related topics, as they play a significant role in determining the strength and durability of the roof structure. The other options relate to different aspects of construction: facades pertain to the exterior faces of a building, trusses are structural frameworks typically used for bracing angles and loads, and beams are horizontal members that carry loads from the roof down to vertical supports. Each of these plays an important role in building construction, but in the context of the lateral sides of a roof specifically, rafters are the accurate term.
