Waterproofing is essential on a flat roof. That’s why it’s important to make sure your roof has adequate measures in place. But what’s the best way to go about it? That’s exactly what we’ll tackle in this post. Read on as we discuss how to waterproof a flat roof.

The importance of waterproofing

Unlike pitched roofs, flat roofs don’t have a clear slope to their surface. They have a low pitch which directs water gradually away from the centre of the surface. To achieve this, it’s imperative that the surface is completely waterproof. Any breaks in the waterproof material allow water to penetrate the roof. This can cause damage to your roof’s internal structure or cause water to leak into the property. Essentially, it’s something that needs to be rectified as soon as possible. Here are some of the best ways to do it:

  • Waterproofing with resins

Over the past few decades, products have been developed to allow for quicker waterproofing of roofs. Specifically, specialist resins have been developed which can be applied to the surface and provide a waterproof layer. Because they’re liquid-based, the resins provide a seamless finish on the surface when applied correctly. Using a brush or roller, professional contractors can cover every twist turn or join in the roof’s surface. This is particularly useful on roofs with skylights or tricky gutters and flashing. This flexibility means it can be applied to roofs which have become inadequately waterproofed over time – as well as being used to waterproof newly installed flat roofs.

  • Torch on membrane

Another option is torch on membrane. This is a sheet membrane made up of rubber and bituminous material. It’s completely waterproof and durable, meaning you can expect it to protect your roof long into the future. As the name suggests, torch on membrane requires heat to be applied to the material to hold it on the roof. It can be applied in patches to cover exposed areas or to waterproof full roofs when newly installed. Because it requires torching to apply, torch-on membrane should not be installed by non-professionals. As well as the safety risks, DIY installation will likely leave your roof vulnerable to damage in the future.

Is it time to replace?

These options are the best solutions when it comes to waterproofing a roof. And they can be used as a temporary measure to repair roofs which have begun to leak because of poor waterproofing. However, in most cases where a leak has started, flat roofs should simply be renewed. Once water has penetrated the roof, it can leave long-lasting damage in the structure of the roof. A thorough professional survey is the best way to find out the right course of action for your flat roof.
