Choose the right material for your flat roofFlat roofing is a popular option for garages, extensions and a wide variety of commercial buildings, and the roofing style has many benefits. Compared to pitched roofing (where two slopes meet to form a pitch), flat roofing is generally more affordable – both in terms of installation and maintenance. Many homeowners view flat roofs as a more efficient use of space, as they are able to easily fit solar panels or create a rooftop garden. While flat roofs have many benefits, there are plenty of different materials that can be used to build them, and choosing the right type of flat roof for your property is fully dependent on your needs.

Here are just some of the types of flat roof you can choose from for your home, and the advantages and disadvantages of each.


Felt is a low-cost, high-performance option that can be applied to a range of flat roof styles. Torch-on felt roofing is easy to apply, strong, durable, versatile and cost-effective, but the disadvantages are that it cannot withstand impact as well as other options, and it does not react well to excessive heat or UV light. Felt roofs usually consist of three layers – a perforated underlay, a layer of underlay felt (about 2mm) and a thick layer of felt (about 4mm) – which are applied to the roofing structure using heat.

Asphalt is an extremely versatile material, making it ideal for flat roofs that have slopes or features that need to be worked around (such as roof lanterns). It is applied to the roof as a liquid while it is still hot, and then moved into shape. Once cooled, asphalt is incredibly durable, and modern asphalt roofs can last up to 40 years. The material is slightly more expensive than felt, but it is more resistant to impact and damage.


Rubber flat roofing is a type of single ply membrane roof, which is a high-performance, lightweight and flexible option. The benefits of rubber flat roofs are that they are affordable to repair, durable and weather resistant. The downside to rubber roofing is that the initial cost of the roof is higher than other options.


Fibreglass flat roofs are strong and durable, and, if they are well-maintained, they can last up to 40 years or more. They generally cost more than felt and rubber options, as they are more difficult to install (mainly because of the inflexibility of the material). As well as looking amazing, fibreglass flat roofs are arguably the most high-performance option available.
