Design Considerations

Flat roofs are known to be remarkably versatile and create a range of design possibilities. There are two benefits to this versatility: first there is the virtually limitless design possibilities which means green roofs can be incorporated as recreational spaces or natural habitats, photovoltaic arrays added for energy production, and then there are very specific and strict requirements in terms of insulation and waterproofing.

The flat roof also offers some very practical advantages including easy access. When a roof area is formed into a terrace or planted, the building gains more than simply an attractive exterior. It is also enhanced by the creation of extra living space – whether in a new build or as part of refurbishment. A flat roof is the ideal place for a PV installation as it provides an unobstructed space that is perfectly positioned to catch as much sunlight as possible. At the same time, a flat roof permits optimum utilisation of the interior space, as there are no sloping ceilings. All in all, a flat roof offers many advantages for everyone.

Explore the design considerations of a flat roof, green roof, PV flat roof, and a blue roof.

Flat roof design considerations
Flat roofs are regarded as remarkably versatile, and open up design possibilities unlike any other roof form. There is the virtually limitless design possibilities which means green roofs can be incorporated as recreational spaces or natural habitats, PV arrays added for energy production, and then there are very specific and strict requirements in terms of insulation and waterproofing. Learn more about the design considerations of a flat roof.
Green roof design considerations
There are fundamental principals that apply to the design of a green roof, regardless of the proposed landscaping, location or climate. The specified solution must replicate nature within the build up and be able to support the vegetation. Learn more about the design considerations for green roofs.
PV flat roof design considerations
In the UK, PV is the most popular renewable energy and its deployment is rising rapidly across the globe, particularly because climate change and resource scarcity are on the agenda of every government and major corporation in the world. Learn about the design considerations for PV on a flat roof.
Blue roof design considerations
The key sustainable urban drainage solution (SuDS) design is the principle of dealing with rain water as close as possible to where it falls. This means that blue roofs are now fundamental to many drainage plans. Learn about the design considerations of a blue roof.
