Roofs can be defined as the uppermost part of a building covered with a structural covering for protection against the weather. It is beautiful to have a roof with different shapes & geometry and covered with a variety of materials. Roofing materials must be chosen and designed based on the conditions of the climate and the surface to be covered
Requirement of a Roof
The type of roof for a building should be chosen after considering the climatic conditions as well as the material availability. In order for a roof to be well planned, it must meet the following requirements.
- Water should not enter the structure and drainage should be efficient.
- It should be strong and stable enough to support the dead and live loads.
- Protecting the building from rain, sunlight, wind, etc. should be effective and durable.
- The building should provide adequate thermal insulation.
- It should be soundproof.
- Ensure that it is well drained
- It should be fireproof.
- Water-proofing arrangements should be efficient.
Types of Roof
Generally, there are three types of roofs.
- Pitched or Sloping Roofs.
- Flat Roof.
- Curved Roof.
In this post, I will give explanations of the different types of pitched roofs.
- It is a common type of sloping roof which the slope is in two directions. The two slopes meet at the ridge.
- When two pitch areas of the roof meet, it forms a triangle-shaped spot called a gable.
- Among the most popular roof types in India, this is simple to construct, sheds water well, and offers good ventilation.
- Typically, this type of roof is found on huts, private bungalows, villas, and chalets.
- This type of roof is formed by four sloping surface in four directions.
- In hipped roofs, there are normally four sides, two of which are triangles, and two of them are trapezoids.
- In high wind areas, these roofs are more stable than gable roofs.
- During the warm summer months, the hip roof can provide extra shade due to the extra eaves on all sides.
- The roof slopes in two directions, like a gable roof, but there is a break in each slope. The slope of the upper slope is shallow, while the slope of the lower slope is steep.
- The advantage of gambrel roof is to increase the height of headroom from inside the building.
- Because of its design, it gives elegant aesthetic and permits for increase the space for storage or living space beneath its steeper sides.
- This roof is similar to hip roof, having slopes in four directions but there is a break in each slope.
- It is also similar to Gambrel Roof but difference is it has same profile on all sides.
- Lowering a roof that would otherwise be very tall, they are able to maximize headroom in the upper floors
- Deck roofs have slopes in all four directions, like hip roofs, but a plane surface is formed at the top.
- Types of Material used in Deck Roof are steel, concrete, cement, wood.
- It is important to choose the right type of roof deck based on the weight. It is
