Alumasc lead the way in Blue Roof drainage development


As rainfall events become more extreme and our weather patterns continue to change, Alumasc’s Harmer Drainage experts are at the forefront of research and development of a new concept in UK roofing.

Blue Roofs see a shift in emphasis regarding roof drainage. The main priority is no longer about removing rainwater from a roof as quickly as possible, but is now more focussed on how and where the water on a roof can be stored, within the limits of the building.

Working alongside Ramboll Consulting Engineers, Alumasc recently held a presentation to a number of CIBSE and SoPHE engineers, looking specifically at Blue Roof potential, drainage engineering, flow control and waterproofing.

In December 2010 Alumasc was approached by Ramboll Consulting Engineers to design a fully engineered Green Roof drainage proposal for the UK’s first Blue Roof project, Zenith House in Hendon. The design brief was required to meet Local Authority discharge rates and address Environment Agency requirements by allowing the controlled release of water over a predetermined time span.

Alumasc devised a concept Blue Roof drainage system based on their Harmer Drainage range and following extensive testing, the system is now fully developed and being installed.

The presentation, which was recognised as counting towards CIBSE CPD requirements, was an undoubted success, with attendees acknowledging that Alumasc’s concept of Blue Roofs is set to become popular due its simplicity and effectiveness.

Harmer Roof is the market leading system for rainwater collection and features technically sophisticated ranges that ensure trouble-free performance for all roof drainage applications in both warm and inverted roof construction.
