Types of Roof Structure

Roof Structure refers to the framing and roof covering for detached houses in temperate and cold climates. This type of structure is usually made of timber and can take a variety of shapes and materials. There are several types of roof coverings available, including metal, slate, and tiles. Read on to learn about the different types of roof structures.

The first layer of roof structure is the rafters and trusses that support the sheathing. This part of the building construction includes drainage features, which allow water to roll off the roof. The rafters and trusses are made from plywood, wood plank, or waferboard. They are placed one above the other in a triangle.

The roof structure is the framework that supports the roof build-up and protects the building from the elements. Generally, a building’s roof structure is made from a series of structural members, such as rafters and trusses, which are fixed or tied down to masonry walls. The roof structure is also an aesthetic component of the building.

When building a new roof, it is vital to follow IBC/ASCE standards for the building and roof structure. These standards provide information that is needed to properly construct a roof, including the type of material, roofing material, and roof HVAC equipment. It is also important to understand the different types of loads that will occur on a roof. If the structure is not designed for changing weather conditions, it can lead to structural damage.

One of the most common types of roof structure is the collar beam structure. This structure is a common choice for utility attics. However, the length of a collar beam should not exceed 3.5 meters. Brick elbow walls can be used to keep interior height within the required limits. The purlin-collar beam truss is another option and is often used for larger spans.

Purlins and rafters are a part of the roof structure. The rafters support the roof decking and provide support for the external roofing material. Purlins provide additional support for a strong roof. Purlins are most important when the roof is subjected to high winds. Steel purlins are often used for this purpose as they provide better support than wooden ones.
