Roof Structure & Beams

Weight of the Load

• The weight of the load is one of the most important considerations when building a house. If the walls and the roof cannot support the weight of the finished elements, the house will cave in or fall over within a matter of years. Beams have to be capable of supporting their weight and insulation, waterproofing and finish material.

Exposure

• The type of climate in the house's location determines the roof's material as well as its structure. For example, not all climates can support a flat roof with wooden beams. A flat roof might work in a dry climate, but a sloped roof is required to shed water where rain is a constant threat.

Type of Weather

• Climate isn’t the only concern regarding a roof's structure and material. Weather is also a major concern. For example, a flat roof won’t work in an area that has heavy snowfalls because the weight of the snow will cause the roof to cave. Also, a sloped roof structure has its own risks in a hurricane-prone area with high wind.

Material Choice

• The type of material used for a roof depends on the type of support needed as well as the location. Although wood works well for covered roofs, it shouldn’t be used for exposed sections of roofs because it eventually rots from subjection to weather even when it is treated against water damage. Steel beams and framing are sometimes needed rather than wood, and the house's engineer and architect can help determine what is best for the area.
