Choosing the roofing is as important as building the foundation for a home. Whether you are choosing a roof for a new home or building, or thinking of changing the roof of an existing structure, you will need to consider many things. The type of roof you choose not only affects your building’s appearance, function, and maintenance cost, it also affects the level of security, stability, and protection that your home has. 

In general, there are two types of roofs you can choose from – flat roof and pitched roof. The following information helps you understand the type of roof to purchase. 

Types of roofs

Flat Roof

A flat roof is also called a level roof, because it is at the level of the building structure’s height. Being flat doesn’t mean that the roof will not have falls to run off rainwater from the sides. Flat roofs do have falls but it is not as prominent as pitched roofs. In contract, pitched roofs have slopes that ensure no water is retained on the roof-top. 

Flat roofs are common in regions with warmer climates. They are also easier to construct. Flat roof construction is generally done with RCC and is expensive in India compared to truss roofs.

The flat roofs are prone to water leakage if they arent waterproofed properly and the concrete transfers heat. Cool roofs are a variation of flat roofs delivering higher solar reflectance and thus reducing the transfer of heat into the home or building environment and is made by painting the RCC roof.

Pitched Roof

Unlike flat roofs, pitched roofs have slopes of more than 10 degrees. However, the acuteness of the slope is determined based on a variety of factors. The downward slopes are generally of two parts, each part starting from central ridges. However, depending on the roof design, they can be single part roofs as well. 

There are many types of pitched roofs such as mono pitch roof, couple roof, closed couple roof, collar roof, and purlin roof, truss (large section), and trussed rafter. Plain or interlocking tiles, felt, slates, and battens are the common materials used to manufacture pitched roofs. 

Pitched roofs are often used in regions that experience high snowfall, ice formation, rainfall, and winds. Roofing tiles and slates used in pitched roofs are resistant to externalities such as water, fire, snow, and ice. It has now become increasingly common to see solar panels fit and integrated into pitched roofs. Several roofing solutions and roof sheet manufacturer companies such as Onduline provides provisions in their onduline roofing and onduvilla to install solar panels, ensuring that the building owner has a source of renewable energy. 

Advantages of flat roof

Flat roofs have compact design. They are a viable alternative for commercial establishments, homes, and garages.

  • Although flat roofs don’t have a slope, it avoids a need of false ceiling inside the house for light fixtures.
  • A building’s height will not increase with a flat roof. So those who want a taller building can use a flat roof. 
  • Versatility. Flat roofs can have roof-top balconies, gardens, and even smaller roofed structures for leisure and relaxation. 
  • Flat roofs facilitate vertical extension of the building. it is easier to construct upper floors . Whereas pitched roof must be dismantled making the process complicated.
  • Flat roofs does not catch fire easily.

Advantages of pitched roof

  • Pitched roofs have timeless appeal. They look elegant and give the home a distinct appearance. Sloped pitched roofs are often used in combination with flat roofs to create hybrid designs. 
  • Pitched roofs can be constructed such that they provide room for creating lofts – which are habitable areas directly under the roof. This area can also be used as an attic. 
  • Pitched roofs are used in regions with heavy or moderately high rainfall. The sloped design of the roofs ensures that rainwater safely drains away. There is no scope for water stagnation atop the roof. 
  • Pitched roofs are considered to have higher longevity. This is because the materials used in construction are durable and resistant. 

Pitched roofs vs. flat roofs

A pitched roof provides for better aesthetics. A flat roof has can make for taller buildings, and is suitable for warm environments. Nevertheless, both types of roofs have their advantages and disadvantages. It all comes down to personal preference, the type of building, budget, environment, and long-term goals.
