A blue roof is an engineered SuDS solution which is closest to source and designed to manage rainwater better where it lands. Offering certainty by design to control the discharge rate of the roof as part of the wider drainage and flood risk strategy.
Climate change is creating more extreme weather events with longer and more intense storm events leading to a greater need for SuDS solutions particularly in urban areas.
A blue roof mimics the natural environment to slow the discharge of rainwater protecting the building and the wider drainage system from flash flooding.
A blue roof is a roof designed to absolute zero falls in compliance with BS6229:2025. It comprises of an area to store water during a storm period and a flow control device to slow the discharge of that water. The depth of the area and the size of the orifices in the device are defined by a calculation we run to comply with the planning requirements of the site.
Attenuation at roof level be that a podium or many stories higher can eliminate the risk of below ground drainage systems such as contaminated land or archaeological findings.
As an engineered SuDS solution you gain greater certainty than that of an outright natural SuDS system, such as a green roof or a planter.
Utilising the outlet as the flow control device we utilise a simple number based setting to allow for clearer quality assurance both at installation and for ongoing maintenance.
Well designed SuDS systems can contribute to BNG (Biodiversity Net Gain), UGF (Urban Greening Factor) and BREAAM credits.
The original and industry renowned second generation hot melt system. For use on all inverted roofs, podium decks, living roofs, blue roofs and car park decks.
Hybrid waterproofing system combining benefits of hot melt systems and polymer modified bitumen membrane technology.
Blue roofs can be used in isolation or as part of a wider range of roof finishes offering a number of complimentary benefits.
A flat roof is ideally suited to generate electrical energy via a photovoltaic array. Through the installation of an Axter Solar PV system, the flat roof can easily be converted into an electrical generator producing clean efficient electrical energy to power the building, the local community or feed back into the national grid.
Green roofs are set to play a big part in the future of sustainable architecture.
