Roof shingle

Bitumen roofing products are available in 5 colours and weigh only around 11.5Kg-m2. They must be installed fully supported on a timber deck. Manufactured in a continuous process starting with large rolls of organic felt on to which other components are layered. The felt is impregnated with the hot bitumen which is then coated with a stabilizer to the top and bottom. Coloured granules are dropped onto the top surface, while a talc is spread across the back to prevent the shingles from sticking together when packaged. Cooling rollers press the granules firmly into the hot bitumen. The material is then accurately cut to size, packaged and wrapped for shipment.
