Flat Roofing

Flat roofing is a roofing design that features a low or nearly horizontal slope that are usually found on commercial buildings, industrial building, and some residential buildings.


There are many advantages and disadvantages to flat roofing such as:



  • Flat roofs are usually more affordable to construct and maintain as they have a simpler design and reduced materials are used compared to a sloped roof.
  • Flat roofs can often be utilised for various purposes such as a rooftop garden, solar panels or equipment for heating, ventilation, or air conditioning systems.
  • Flat roofs are easier for access and working on therefore installation, repairs, or maintenance can easily be undertaken.
  • Flat roofs can provide architects the flexibility so modern or minimalist designs can be sought. This can result in unique building designs and shapes being created.


  • Flat roofs are prone to poor drainage as there is a lack of a slope that helps water flow away. Ponding water can lead to leaks and other issues if this isn’t dealt with correctly.
  • Flat roofs must be sealed and maintained correctly as they are more susceptible to leaks from snow accumulation and rainwater damage.
  • Flat roofs are prone to challenges if you decide to insulate and/or maintain energy efficiency as they are more exposed to elements.
  • Flat roofs have a much shorter lifespan than a sloped roof due to increased exposure to elements and the potential of water damage.


In conclusion proper design, decent materials and professional installation and maintenance are essential for flat roofs to achieve a good lifespan, however this is far less costly than a sloped roof. Flat roofs can be used as an outside space if you lack a garden. Due to maintenance being required more regularly than a sloped roof to achieve a longer lifespan, careful consideration is essential to make sure this is a practical choice for your budget and building.
