Clean-lined, contemporary, and cost-effective — the modern choice for residential and commercial extensions.
Flat roof extensions offer a sleek, minimalist profile that suits both contemporary new-builds and older properties seeking a modernising addition. The low-profile roofline is ideal where planning restrictions limit height, and the flat surface creates the perfect platform for roof lanterns, large rooflights, or even a green sedum roof.
Our flat roof builds use modern, high-quality waterproofing systems including GRP (fibreglass) and EPDM rubber membranes, ensuring longevity and weather resistance for decades. All our flat roofs are fully insulated to current building regulations and beyond.

The flat surface is ideal for frameless rooflights and roof lanterns, flooding the interior with natural overhead light that pitched roofs simply can't match.
Flat roofs require less material and labour than pitched alternatives, making them the most cost-effective structural choice per square metre.
The low profile of a flat roof extension often makes it easier to gain planning approval, particularly in conservation areas or terraced street scenes.
Flat roof extensions and contemporary builds we have completed for clients across the UK.
