When you’re working on a new-build commercial property or carrying out renovations on an existing one, the roof is an important part of the job. Choosing the right materials for a commercial property’s flat roof will ensure that the roof is suitable for the needs of the building, and that it’s as long-lasting, durable and low-maintenance as possible. With this in mind, here are just some of the high-quality materials you can choose from for the flat roof on your commercial property, as well as some of the benefits that each material provides.

Dealing with residential and commercial roofsSilicone

Liquid roofing uses a silicone coating to cover the entire roof or an area of the roof. The advanced polymer solution can be used for new builds as well as roof replacements. It is cost-effective (liquid roofing costs about 70 per cent less than a standard replacement roof), durable, flexible (i.e. it suits a wide range of property styles), and quick and easy to install. Also, as it is applied cold, it is a completely safe option. One of the biggest benefits of liquid roofing for commercial flat roofs is that it protects against water damage and leaks.


One of the most innovative flat roofing solutions for commercial properties at the moment is rubber roofing. Solutions like RubberBond FleeceBack™ EPDM are popular for new and replacement roofs alike because they have a high-performance waterproofing system that makes the commercial roof strong, long-lasting and leak-free. It is also safe, smooth and quick to install, which is ideal for the tight schedules of commercial building projects.

Single-ply bitumen felt

A common material for commercial flat roofs is single-ply bitumen felt. It provides a smart and attractive finish and is also popular because of its flexibility – it can adapt to changes in the weather by expanding and contracting. It is important to keep in mind that single-ply bitumen felt is not ideal for flat roofs that see regular footfall, as this can cause it to tear.


Fibreglass roofing is a liquid solution that is applied cold and provides a watertight seal across the roof. It is an attractive option for commercial flat roofs, as it has a fine, smooth finish and is available in a wide range of colours. Fibreglass roofing systems, such as CrysticROOF, are also popular because of their versatility and superior performance.
