How long does it take to install a Silent Roof. When installed on Profile Metal Roofing (PMR) structures and the like, the Silent Roof Material (SRM) is simply rolled out across the roof from eave to eave up and over the ridge of the roof. Each ‘strip’ will be 1m wide. The next strip is laid upside-down on to the first strip and ‘stitched’ together using PVC cable ties. This strip is then flipped over to lie adjacent to it’s neighbour and the process repeated. Using this method a considerable area of roof can be covered with SRM in relatively short period of time typically 60 square metres per hour with a team of two fitters is typical. This link will take you to a time lapse video of SRM being installed on a 6,000 square metre roof.
