Flat roofs are common on commercial premises because they are practical for large buildings. A flat roof has a minimal pitch to allow drainage. This roof usually has a concrete base overlaid with a membrane such as TPO (thermoplastic olefin) and PVC (polyvinyl chloride). While they are common for commercial buildings, flat roof installations are popular in residential buildings, especially large apartment blocks. So, why should you go for this type of roof? 

1. Extra Usable Space 

As mentioned above, a flat roof has a minimal pitch. You can use the roof as a viable area for leisure and business. Rooftop cafes and restaurants are popular uses for flat roofs. It is also suitable for storage space. It adds value to the building because there is more usable floor space. 

2. Easier to Install Add-on Features 

A flat roof installation is more practical for adding add-on features such as solar panels. These require less structural support and can be installed easily on the roof. You can also install roof ventilation easier. It is also easier to maintain, upgrade or remove these structures. 

3. Easier Installation and Lower Maintenance  

A flat roof installation is easier to install than other roofs because you do not need to use complex roofing solutions. There is no need for an extensive roofing substructure; the underlying concrete slab is the support structure. 

Installing roofing membranes is relatively easier than other roof types and takes a shorter time. Also, flat roofs are low-maintenance because roof cleaners do not need special safety tools to work the roof.   

4. Higher Energy Efficiency  

A flat roof is more energy-efficient than other roofs because of the design. It does not have underside space to trap warm air like a sloped roof. Flat roof membranes do not retain heat like other materials. 

It reduces heat radiation to the space below, which keeps room temperature cool, hence a lower need for air conditioning. It is also easier to install roof ventilation systems like roof turbines.

5. Versatility   

Flat roofs are more practical for large buildings, including commercial buildings and apartment blocks. Flat roofs are more versatile than other types of roofs because they can fit different building sizes and shapes. You also have  different options for roofing, including:

  • Built-up roofing 

  • Modified bitumen

  • EPDM rubber roof

  • Spray polyurethane foam roof

  • Thermoplastic  membranes
