What Is a Roof Coating and How Long Can They Last?

Roof coatings are an effective way to protect your roof from the weather. While they all have one thing in common – coating your roof – there are several types of roof coating which offer different benefits as well as varying lifespans.

In this post, we’ll discuss the different types of roof coating and how long they will protect your roof.

The different types of roof coating

One of the most well-known groups of roof coating are those used directly on flat roofs for waterproofing. These come in various types such as GRP (glass reinforced plastic) or EPDM (ethylene propylene diene monomer – or rubber for short).

These coatings are used solely for waterproofing on flat roofs – anything below 12.5 degrees, but typically between 1-4 degrees. They do a reasonable job as the roof’s main covering, preventing water from building up and getting into your property.

However, another group of roof coatings are available specifically for roofs with a higher pitches. A cork-based coating can be used on roofs with a pitch of 4 degrees or more to waterproof the existing roofing materials.

Cork-based coatings are sprays which are applied in a thin layer to ensure a complete seal across your roof. As well as waterproofing, it can also provide added thermal insulation and acoustic reduction from noisy weather like rain, wind and snow. Cork also has the added benefit of being eco-friendly, taken from the bark of a tree which can quickly grow back.

How long do they last?

The lifespan of your roof coating depends on which type of coating you choose. Most roofing products come with a warranty of up to 20 years. That means they will stay on your roof and provide some form of waterproofing over that period.

However, what you’ll find in most cases is that they’ll need redoing again and again. Despite being warrantied for 20 years, roofing materials lose their strength and waterproof qualities over time. That means you’ll need to repair, maintain or reapply them a few years down the line.

In contrast, cork is naturally very hard wearing. This means that it will continue to perform at its best beyond any warranty you’re offered. That said, you’ll still get a guarantee of 15 years to protect you from an installation faults.
