An over-roof is the solution to installing solar panels on fibre-cement and older asbestos-cement roofs. It eliminates fixing issues as the PV structure only connects to the rafters, and therefore does not disturb the asbestos cement. It is fully endorsed by roof sheet suppliers.
A series of rafters over the roof, connected to one another by sturdy aluminium beams, directly support the PV modules. The small number of rafter mounting points are fitted with a flashing system, eliminating any chance of leaks in these areas, with the remaining roof surface left untouched.
