Roof Top Waterproofing For Flat Roofs

EPDM Roof Top Waterproofing Benefits

Today your choice of a roof top waterproofing membrane will be very different from twenty years ago. Mainly because of the quality and the types of membranes available that have evolved so rapidly over the years. However, one thing is still as important today as it was back then that as a homeowner, quality waterproofing can make a world of difference to the longevity of your roof.

Over the past several years, liquid applied membranes have been proven to be economical, feasible and much more environmentally friendly than any other solution or materials used. In South Africa, where it can become immensely hot during the summer, the membrane or coatings we choose also need to be heat resistant.

Fortunately, our years of experience in this industry have allowed us to gain a great deal of insight into what works for most concrete flat roofs and homeowners’ budgets. We also have a much better understanding of what will give you the best bang for buck performance across the entire surface of the roof.

Modern Liquid Membranes for Waterproofing

One of the best features of many modern membranes available is that they have the added benefit of being a reflective white color. The reflective nature of the coating helps to reflect away much of the UV rays from the rooftop, which in turn lowers the temperature when the roof is exposed to extreme heat during the summer.

The other advantage of roof top waterproofing is that it extends the service life of your flat roof. Now for the environment, that means not having to put several tons of scrapped roofing materials into the South African landfill. Using waterproofing, we can almost guarantee that there are a few thousand tons less scrap roofing material ending up in landfills.

Using a Waterproofing Membrane For Your Flat Roof

The success of your waterproofing project depends a great deal on the right application or coating. Coating your flat roof does not guarantee that the roof will become waterproof, mainly because many coatings only protect the roof from degrading. UV rays cause degradation over a period of several years which can take longer for roofs that use good construction material.

Acrylic coatings, for instance, re-emulsify in water, which means that the product is an absolute failure if the water stagnates on the roof, which in South Africa is very common during the monsoon. That’s why you should only consider a roof coating that protects it from the water, while the roof should also have an inclination that allows water to flow into the nearby drain.

Water that collects on the roof can also damage the insulation which is another reason why we strongly emphasize efficient drainage solutions.

You have many different things to consider when choosing the right liquid to apply on the roof for waterproofing purposes. For starters, you will want to consider:

  • If the substrate is dry
  • If the ambient temperature and that of the substrate are within accepted ranges?
  • Does the roof meet the required consumption?
  • Respect the drying time of each layer. Multiple layers aren’t uncommon for good waterproofing

As professionals with years of experience, we know how to apply the waterproofing material for the best results. We also ensure that our process complies with the manufacturer’s application instructions, making the entire process safe and free from potential errors.

Our professionals have been through specialized training, have indepth product knowledge, and that’s why we are the best people for the job.

Advantage of Using EPDM To Waterproof a Flat Roof

We use EPDM to waterproof a flat roof regardless of size or where it might be located. In our experience, the material offers a couple of unique benefits that can’t be found with anything else available.

Key advantages of using EPDM include:

  • We don’t need to use a hot torch     
  • There is no need for electricity
  • The coating is chemically sealed, which ensures that it bonds well with masonry and wood
  • EPDM is naturally elastic; its flexibility is what makes it so durable
  • Our attention to every detail ensures that the end result is a durable coating that protects your roof from water and dampness
  • The coating can be applied on both masonry and wood alike
  • RubberGard™ EPDM membrane is eco-friendly and recyclable and has been certified by the Singapore Green Labelling Scheme (SGLS)
  • Waterproof Lab’s Flat Roof Waterproofing System leads the race in the market

In our experience, EPDM is a resilient and strong roofing material that can easily last beyond 50 years, but only if it is installed correctly. That is what makes it ideal for South African home roof and deck.

The Best Cost To Performance

Many times property managers and building owners don’t think much about the functionality and reliability of the waterproofing solution used. However, as professionals, we always tell people that the costs associated with maintaining and repairing a flat roof during the life of the roof membrane and then recoating it at the end of the warranty period can add up. The costs can skyrocket for polyurethane materials too.

The cost of inferior waterproofing solutions can often appear low upfront compared to high-quality waterproofing, but it soon balloons exponentially. On the other hand, when you choose a high-quality waterproofing solution like the type we use, the higher price upfront helps keep maintenance costs down, and there are fewer repairs needed as a result. When the time comes, the recoating is also comparatively more cost-effective.
