Solarspot flat roof systems

The Solarspot spun aluminium flashing makes it perfect for any flat roof application. The rigid strong, flashing is perfect for GRP or single- ply roofs, and heat-resistant for any hot-process membrane system.

The unit is also a great option for green roofs providing a more aesthetically sympathetic solution than a curb-mount option.

The main flashing chassis can be heat-moulded to allow it to be formed over the profile of the roof tiles, and the sleeve adhesive flexible weathering-strip on the lower edge holds the flashing in-place, whatever the elements throw at it.
