How Long Does Roof Waterproofing Last?
Roofing waterproofing can last anywhere from 10 years to over 20 years. It all boils down to the quality of materials used, the type of waterproofing and how well it was applied. Premium waterproofing solutions like RubberGard can last for as much as 50 years!
It is one of the most asked questions by South Africans who either want to get their roof waterproofed or have an already waterproofed roof and are now trying to calculate how many more years they have left on it. The fact is, it is hard to tell how much more life your waterproofing may have left without a thorough examination.
Sure, basic waterproofing membranes, if they are of good quality, can last around ten years, but under the right circumstances, they can last longer. Yet poor quality, which is also often cheap waterproofing, does not go the distance, unfortunately. That’s why most South Africans are better off paying upfront for quality, which will save them money in the long-term.
Use A High-Quality Membrane
Not all waterproofing membranes used in South Africa or even internationally are made equal. Each one has its own specific set of properties, which can mean that they have a set of strengths and inherent weaknesses. That’s also one of the reasons why homeowners should leave choosing the right waterproofing membrane to an expert they trust.
Generally, the waterproofing membrane used in South Africa should have robust waterproofing abilities but also be able to withstand harsh climates like intensive rains and strong heat. Unfortunately, not many membranes can easily stand up to the beating of the South African climate. That’s why the right choice factors greatly into how long the membrane will last. Roofing materials like RubberGuard has what it takes to stand up to the elements in Africa with zero maintenance.
Workmanship Matters
Even the most expensive, highest quality waterproofing membrane, if installed incorrectly by inexperienced professionals, will not last as long as it should. While waterproofing membranes are meant to keep water out, once water somehow gets through them, it starts damaging the membrane, so there shouldn’t be any weak spots.
There are two primary types of waterproofing membranes, as we’ll examine below.
Sheet Based Membranes
The most common types of waterproofing membranes are sheet type, usually premanufactured for specific dimensions. These are often sold in rolls, which make it quick and easy to deploy across the roof.
Bonding the sheet to the surface is done using heat. Heat is applied to the sheets, which also helps to prevent gaps from forming between them and the roof’s surface. However, multiple sheets are often pieced together to cover a single average-sized roof.
When applied correctly, it can cover just about any size surface in a short time. That said, roofing experts will tell you that applying it across an irregularly shaped roof can be challenging. Plus, covering spaces where horizontal and vertical plans may join another challenge.
The lifespan of this type of waterproofing system is highly dependent on the quality of the membrane and the professional doing the job. On average, they can last ten years, if not more.
Liquid Waterproofing Membranes
Liquid-based waterproofing membranes are the opposite of waterproofing membranes in many ways. These membranes are more flexible regarding how they can be applied and may not be restricted to the size or type of roofing.
Liquid membranes are applied using roller brushes or spray apparatus, which is meant to cover the surface area evenly. The challenge for a contractor is to mainly retain an even layer. That’s why applying this type of waterproofing takes longer and hence more expensive. The expertise and effort needed for it mean only a few professionals offer this service in South Africa.
The other downside of liquid-based waterproofing membranes is that they take much longer to cure. In some cases, they can take up to a week to fully cure. But on the upside, they cover up protrusions and joints better than any other system.
Liquid waterproofing membranes can also last for several years, given that the membrane isn’t damaged by hail, falling branches and other types of debris.

How To Extend The Life of Your Roof Waterproofing?
The best way to extend the life of your roof waterproofing membrane is to stay on top of its current condition. Make sure to get on top of the roof and inspect the membrane for cracks, chips, scratches and tears. This is especially important right after violent weather like a hurricane, hail, storm etc. If you notice that the membrane is damaged, hire a professional to fix it right away.
Addressing issues with the membrane in time, before there is potential water or moisture ingress, will save you a lot of money in the long term. Not only because it saves you from having to replace the membrane but also because you are doing the roof a favor. Remember that prolonged exposure to water or moisture can lead to all types of problems with your roof.
The other way to extend the lifespan of your waterproofing membrane is to invest in a high-quality one and one that’s applied by a renowned expert. While it may cost a little more, you have the peace of mind of knowing that your investment is safe, at least for the next ten years.
Final Word
The critical question you need to ask a waterproofing question is not how long your roof’s waterproofing will last but which membrane is the best for your roof.
Depending on where you live in South Africa, the size of your home, its age and the shape of the roof, the choice of the membrane that an expert recommends will vary a bit. That’s why it is essential to find a reputed expert who will start with a thorough examination of your roof and make a recommendation accordingly.
