If you are looking for a roofing option that is versatile, cost-effective, and durable, a flat roof might be just what you need. Flat roofs are becoming increasingly popular in South Africa, and for good reason. They offer many benefits that other roofing types cannot match. In this article, we will explore everything you need to know about flat roofs in South Africa, from their advantages and disadvantages to the materials used and maintenance requirements.

What is a Flat Roof?

A flat roof in South Africa refers to a roofing system that has a level surface rather than a sloping one, similar to the definition in other parts of the world. However, in South Africa, flat roofs are commonly used on both residential and commercial buildings due to the relatively mild climate in many parts of the country.

Flat roofs are often constructed using reinforced concrete and may be covered with a layer of waterproofing material such as bitumen, PVC, or EPDM. In some cases, flat roofs may also feature a slight slope or parapet walls to help with water drainage. Flat roofs in South Africa are popular for their affordability, ease of construction, and the extra outdoor living space they provide.

Advantages of Flat Roofs in South Africa

There are several advantages of installing a flat roof in South Africa, some of which include:

  • Affordability: They are often more affordable than other roofing options, making them an ideal choice for those on a budget.
  • Versatility: Can be used for a variety of purposes, such as creating a rooftop garden or installing solar panels.
  • Space: Offer additional usable space, which can be used for storage, entertainment, or as an additional living space.
  • Easy maintenance: Easier to maintain and repair than other types of roofs.
  • Durability: Durable and can last for many years if properly installed and maintained.

Disadvantages of Flat Roofs in South Africa

Although flat roofs offer many advantages, there are also some disadvantages that you should be aware of, including:

  • Drainage problems: Flat roofs are prone to drainage problems, which can lead to water pooling and eventually causing leaks or other issues.
  • Limited design options: Flat roofs offer limited design options, as they are not suitable for certain architectural styles.
  • Poor insulation: Flat roofs can have poor insulation, which can lead to higher energy bills and discomfort during extreme temperatures.
  • Not suitable for heavy snow loads: Flat roofs are not recommended for areas with heavy snow loads, as the weight of the snow can cause damage or collapse.

Flat Roof Prices in South Africa

The price of a flat roof in South Africa will depend on a variety of factors, including the size of the roof, the materials used, and the complexity of the installation. Generally speaking, flat roofs tend to be more affordable than pitched roofs, as they require less material and labor to install. However, the specific price of a flat roof will depend on the following factors:

  1. Size: Larger roofs will require more material and labor to install, and will therefore cost more.
  2. Materials: The cost of materials will vary depending on the type of flat roof system used. For example, PVC and EPDM membranes tend to be more expensive than bitumen roofing.
  3. Roof complexity: If the roof has multiple levels, unusual angles or curves, or requires additional structural support, the cost of installation may be higher.
  4. Roof access: If the roof is difficult to access, such as in the case of high-rise buildings, the cost of installation may be higher due to the need for additional safety measures and equipment.

As a general guideline, the cost of a basic flat roof installation in South Africa can range from around R200 to R400 per square meter. However, prices can vary widely depending on the above factors, as well as the specific contractor or roofing company hired for the job. It is always best to get multiple quotes from reputable roofing contractors in order to compare prices and ensure a fair price for the work.

Materials Used for Flat Roofs in South Africa

There are several materials commonly used for flat roofs in South Africa, each with its own advantages and disadvantages. Some of the most popular options include:

  1. Reinforced concrete: This is a strong and durable material that is commonly used for flat roofs in South Africa. It can be cast in place or prefabricated offsite and transported to the construction site.
  2. Bitumen: Also known as asphalt, bitumen is a waterproofing material that is often used to cover flat roofs in South Africa. It is relatively inexpensive and easy to install but may require regular maintenance to prevent cracking and other forms of wear and tear.
  3. PVC: Polyvinyl chloride (PVC) is a type of plastic that is often used as a roofing material for flat roofs. It is lightweight, waterproof, and resistant to UV rays, making it a popular choice for commercial and industrial buildings.
  4. EPDM: Ethylene propylene diene terpolymer (EPDM) is a type of synthetic rubber that is commonly used for flat roofs in South Africa. It is highly resistant to UV rays and weathering, making it a good option for buildings in areas with harsh weather conditions.
  5. Metal: Metal roofs, typically made of steel or aluminum, are also used for flat roofs in South Africa. They are durable and long-lasting but may require regular maintenance to prevent rust and other forms of corrosion.

Each of these materials has its own advantages and disadvantages, and the choice of material will depend on factors such as cost, durability, and the specific needs of the building.

Maintenance Requirements

To ensure the longevity of your flat roof, it is essential to perform regular maintenance. Here are some maintenance tips for flat roofs in South Africa:

  • Regular inspections: Inspect your flat roof regularly for any signs of damage or wear and tear.
  • Keep the roof clean: Clear debris such as leaves, branches, and dirt from your flat roof regularly.
  • Address drainage issues: If you notice any drainage problems, have them addressed immediately to prevent water pooling and potential leaks.
  • Repair any damage: If you notice any damage to your flat roof, have it repaired as soon as possible to prevent further damage.


Are they suitable for areas with heavy rainfall?

They are suitable for many types of buildings, such as commercial buildings, apartments, and residential homes. However, certain architectural styles may not be suitable for them.
