Flat Roofing


Flat roofing refers to a roofing design characterised by a nearly level or low-sloped surface. This is in contrast to the higher pitched or sloped roofs often seen on residential buildings throughout the UK. Flat roof design is often used for commercial, industrial, and modern building. Flat roofs are constructed with materials such as single-ply membranes (including TPO and EPDM), liquid applied membranes and built-up roofing. Flat roofing is a desirable type of system due to being easy to install, cost-effective, and suitable for accommodating rooftop equipment such as plant machinery and soil vent pipes. However, flat roofing needs proper drainage systems and regular maintenance. This is in order to prevent issues with drainage, water pooling and general wear.


We are one of the UK's leading flat roofing companies. We provide a complete flat roofing service. This includes everything from the installation of new flat roofs to flat roof repairs and flat roof overlays. We are fully accredited in a number of flat roofing systems including GRP, EPDM Rubber, Felt, Liquid and Mastic Asphalt. Our highly-experienced team covers all of London and the South of England, and are fully accredited flat roofing specialists.
