May 1, 2018 9:46 am

More than just providing shelter, cover, and protection from the elements, a roof can affect your property’s overall aesthetic. Additionally, a roof’s design could serve other specific functions.

Your decision to get a pitched roof or a flat roof will depend on your preferences and specific needs. Both types have their share of advantages and disadvantages, which are listed below.

Pitched Roof

The pitched roof is the most common and most popular roofing design for houses. It is known for its sloping, inverted V shape, which is why it is also referred to as a sloping roof.


  • The versatility of this design makes it suitable for any property. A pitched roof can go with most architectural designs and blend cohesively with a property’s overall look.
  • The extra space right underneath the roof can be converted into an additional room (e.g. attic, loft, bedroom, or storage). This is a bonus for smaller houses.
  • A pitched roof is more durable than a flat roof. The materials used for a pitched roof are more superior when it comes to the capacity to withstand weather conditions and wear and tear. Pitched roofs are proven to last longer than other roof types.
  • It is low-maintenance. The sloped angle of the pitched roof makes it easier to clean.
  • The pitched roof’s sloped angle makes it more efficient when it comes to drainage concerns. Accumulated rainwater in the roof will naturally flow down to the gutters and pipes. Therefore, there is minimal to zero chances of water ponding in certain areas of the roof.


  • The initial cost of construction is high as compared to that of flat roofs.
  • Pitched roofs require more time to construct and install compared to a flat roof. The design is more complicated than a flat roof. More materials and intricate work will be needed.

Flat Roof

The flat roof is a relatively new design. It is commonly used in commercial buildings and offices. However, there are some residential properties which have adapted the flat roof design. They are slightly sloped to provide drainage of rainwater.

Using the flat roof as a green roof is becoming popular, especially among properties that aim to be eco-friendly. “Greening” also helps extend the life of a roof, protecting it from UV radiation.


  • A flat roof requires less construction and installation time compared to a pitched roof.
  • The installation cost for a flat roof is cheaper than a pitched roof.
  • Its design is more modern and more suitable to contemporary homes.
  • It has a compact design, which makes it the best choice for garages and property extensions.


  • It requires more attention when it comes to maintenance and cleaning.
  • If not maintained properly, flat roofs become less durable.
  • The drainage system of flat roofs is less efficient. Flat roofs are highly prone to rainwater pooling. However, that issue can be fixed with green roof technology.
  • Flat roofs are not advisable for large properties due to the aforementioned cons.
