There’s now such a wide range of roofing materials to choose from that property owners are spoilt for choice, whether you’re upgrading an existing roof or building a new one (e.g. for an extension).

However, two of the most popular options, especially when it comes to flat roofing solutions, are fibreglass and rubber roofs. But what are the differences between the two? We take a look.

Fibreglass roofs are often referred to as GRP roofs, which stands for Glass Reinforced Plastic, and this solution offers one the most state-of-the-art roofing products available. The material is strengthened through the presence of a resin layer and fine glass fibres, making it highly suitable for flat roofs and other applications.

Benefits of GRP Fibreglass Roofs

Thanks to its composition, GRP fibreglass is one of the strongest roofing solutions on the market, so it’s often chosen for flat roofs where there will be light traffic present, such as balconies and outdoor seating areas.

Its seamless application makes it a high-quality, weatherproof roofing material, ensuring that moisture doesn’t penetrate its surface. As a result, it’s one of the most long-lasting roofing solutions in the industry.

Fibreglass roofing installation is simple if you hire an experienced professional roofer, but as it’s applied as a cold liquid, the process relies on appropriate weather conditions. Your roofer will inform you if it’s too wet or temperatures are too hot or cold to install the fibreglass roof.

What Is Rubber Roofing?

The most common type of rubber roofing is known as EPDM (ethylene propylene diene monomer). It’s incredibly clean and efficient to install, consisting of a single-ply membrane. It’s often used for various flat roof applications, including garages, extensions, sheds and dormer windows.

Benefits of EPDM Rubber Roofs

Rubber roofs are often the more cost-effective of the two options.

Because EPDM is made of rubber, it’s highly flexible, so it’s also used for roofs with uneven structures, easily fitting around features such as skylights and guttering. Applied cold, it’s often the quicker and easier roofing material to install with a strong adhesive used to keep it in place. This is because it consists of one layer, rather than the multiple layers present with fibreglass roofing.

The difference in quality results can also be evident depending on the brand of rubber roof selected. If using a product such as RubberBond FleeceBack™ EPDM, for example, you can expect a roofing system that’s twice as strong as other EPDM solutions. This is thanks to a fleece-reinforced sheet that’s highly resistant to punctures and tears.
