Guide to installation of renewable energy systems on roofs of residential buildings

A review of roof-mounted micogeneration technologies

The increase in uptake of microgeneration systems such as photovoltaic, solar thermal, and micro-wind turbines has resulted in an increase in wind-induced failures and rainwater penetration through the roof envelope. While regulated by a range of British and European standards that ensure they are fit for purpose, there are currently no standards that regulate the mechanical installation on buildings to ensure they are resistant to wind and rain.

This guide provides reviews of roof-mounted microgeneration technologies and considers the reasons for such failures. It also provides best practice advice on wind and weather resistant installation, complementing existing guidance including NHBC Standards and the Microgeneration Certification Scheme. The guide is not intended to replace accredited learning to National Occupational Standards.
