Let’s take a quick look at the three most common commercial and industrial roof types around Johannesburg and the best waterproofing methods for each.
Flat Roofs
Flat roofs made of concrete are a common choice for many buildings around Gauteng. They are cost-effective and provide additional usable space on top of the roof, which is partly why they’re so popular. It is in this space that many businesses might install HVAC units, satellite dishes and solar panels.
To waterproof a flat roof, the best option is to apply bitumen membrane waterproofing using the torch-on method, which provides a continuous, seamless layer of protection. Once this is applied, an aluminium coating should be added to provide sun protection.
This durable waterproofing method can withstand intense sun exposure throughout the summer months while simultaneously standing strong against leaks and water ingress.
Metal Roofs
Corrugated metal roofs of various kinds are widely found among commercial and industrial buildings in most South African metropolitan areas. They are relatively affordable, extremely durable, and last a long time if well maintained.
The best waterproofing method for metal roofs is to use an acrylic or polyurethane coating. Polyurethane or acrylic coatings provide a non-porous membrane that offers great flexibility, excellent UV resistance, and strong adhesion.
Not only do these coatings waterproof metal roofing very effectively, but they also prevent rust and corrosion. This is crucial for the longevity and integrity of metal roofs over time.
Tiled Roofs
Throughout Johannesburg, you’re likely to see a lot of pitched tiled roofs, usually using either corrugated concrete or terracotta tiles. While these are common in residential applications, they’re also widely used in commercial buildings as well, such as office parks and shopping centres.
The best way to seal this type of roof is through the use of cementitious sealant, commonly referred to as roof cement. This is applied as a coating to the roof and is highly effective in closing up any cracks or gaps that may have formed over time.
