• PVOverRoof™ eliminates the fixing issues associated with traditional hanger bolts. PVOverRoof ™ works on fibre-cement (and older asbestos–cement) roofs
and roof sheet suppliers have fully endorsed it.
• The key to PVOverRoof™ is a structure that only connects to the building’s rafters. A series of sturdy aluminium beams bridge between the rafters that
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.
• The PV modules are suspended above the roof surface thus module cooling is maximised. This, along with a module spacing of 20mm, ensures any existing
transparent roof panels still maintain a reasonable light level in the building. If a roof sheet needs replacing, this is easily achieved because only the modules
directly above the damaged roof sheet need to be removed, and with PVOverRoof ™ there are no penetrations into the sheet itself, so consequently there is
no need to strip out large areas as typically applies when using a hanger bolt/rail type solution. The final installation meets all UK snow and wind loading
requirements (subject to a building survey and, if required, frame strengthening).
• PVOverRoof™ also solves any loading problems with timber purlins or lightweight zed purlins.
• With PVOverRoof™ you can enjoy all the benefits of PV on your roof without in any way compromising the integrity or life span of your roof - it can even be
argued using PVOverRoof™ extends the life of the roof. This solution maintains your roof sheet guarantee and bankability and insurance are a given.
