Why do some flat roof have loose stones on the surface?
Loose stones are used to protect the roof membrane from the sun. The sun can damage the high performance membrane over long periods of time. Solar Reflective paint can also be added to reflect the sunlight and therefore protect the top layer membrane. Tecta Roofing use High Performance Membranes that have a mineral finish – this means that one side of the felt is bituminous – enabling the installer to use a gas-gun and torch-on the membrane to the roof surface. The top side of the membrane has tiny minerals embedded into the membrane to reflect the sunlight – therefore there is no need for loose stones. Please contact Tecta Roofing for more information.
