Pros and Cons of Each type of roofs:

The basic purpose of a building is to sustain a roof. A roof is the most fundamental part of a building. The concept of a building evolved from the invention of a roof. The primitive man, in order to protect himself from rainwater, founded the concept of the roof. A room, house, or building is an evolved form of a roof. Today there are several types of roofs, all of which fall under three categories.

  1. Pitched Roofs
  2. Flat Roofs
  3. Curved Roofs

Each type of roof has the pros and cons of its own.

(1). Flat Roofs:

This type of roof is very common all over the world, especially in multistory buildings. Except for the uppermost floor of a building, the construction of a pitched and curved roof is almost impossible. Flat roofs are constructed by means of placing iron or wooden girders on the wall and then the material of the roof is supported by means of the girders or beams. There is another method of construction of flat roofs, and that is the RCC method. In this method, the Steel Reinforced Concrete is used as a roof.

(2). Pitched Roofs:

Pitched roofs are generally constructed in hilly and mountainous regions, where the rain and snowfall is very high. In order to protect the roofs from seeping water, they are conically pitched up. The pitched up roofs, slip down the dumped snow, and unload the roof to maintain its stability. The pitched roofs are classified into two groups:

  1. Single Pitched Roof:

Single pitched roofs are sloped from the only side and the other side remains elevated. The single pitched roof is very easy to construct. As it is a one-panel roof, therefore it does not need any bridge. 

  1. Double Pitched Roof:

The double-pitched roof consists of two plan surfaces. Both the surfaces are attached to each other at a central ridge and the sides of the two surfaces are placed on the load-bearing walls. The surfaces of the roof are known as Gables of the roof. The gables attached at one end make a triangle. The upper angle is about 90 degrees, and the angles between gables and the load-bearing walls are about 45 degrees, thus completing 180 degrees of a triangle. These types of roofs are constructed with the help of a truss. The truss provides sustainability to the gables of the roof.

(3). Curved Roofs:

A curved roof is a roof that has a curved style. Both the pitched and the curved roofs are aimed at the same. Only the style and design are different. A curved roof generally consists of a single gable with one side slope down and the other side is flat (with very little slope). But in some cases, a curved roof is so designed that both the ends of the single gable are sloped down with an elevated center.
