Flat Roofing


Our Flat Roof Services in Norfolk and Norwich

A flat roof requires a different approach to traditional pitched roofing, and these methods of installation have changed and evolved over the years. As the leading flat roof installers in East Anglia covering areas including Norwich, we are at the forefront of this expertise, ensuring through high-quality work that you will receive a roof that is reliable, safe, can stand the test of time, improves your property and gives you excellent value for money.

In order to protect your home or building, we only use flame-free methods of installing and repairing flat roofs. We are approved installers for a number of industry-leading roof system manufacturers, meaning we can work with you to select the best flat roof choice for you. 

(GRP) Fibreglass Flat Roofing Systems

One such flat roof system is GRP Fibreglass. GRP stands for Glass Reinforced Polyester and is a composite material formed by strengthening plastic with fine glass. This is then installed as a seamless roof on your building.

A fiberglass flat roof is one of the most popular solutions across the UK. GRP is reliable, flexible and waterproof; it is simple and safe to install, and the finished product will outlast many competitors. In fact, we offer a 20-year on all GRP flat roofs that we install.

Pick the perfect roof for you: choose an attractive finish, from smooth to non-slip in a wide range of colours. At Iceni Roofing, we use the Stronghold GRP system: discover more about the finishes available here.

Liquid Rubber Waterproofing for Flat Roofs

Liquid waterproofing is one of the most cost-effective ways of making a new or existing roof waterproof. The result is durable, able to last lasting for 25 years or more and can help you save up to 70% on roof replacement costs in many refurbishment projects.

We make use of Res-Tec for our liquid rubber waterproofing: find out more about them here.
