Self Supporting Roofing System

Before you choose to install self-supporting roofing system, here we have described some basic advantages & disadvantages of self supporting roofing system:


  • This type of roof requires less maintenance and has a long life.
  • There is a quick and easy installation of roofing sheet.
  • Roofing sheets are mechanically sealed and free from holes, nuts, bolts, overlaps or sealants. Hence no leakage will occur.
  • Trussless roof is non-combustible. It has a higher tensile strength which makes it stronger against accidents like fire and also resistance to extreme weather conditions. Even monkeys also can’t damage it.
  • Distinguished architectural shape and flexibility of colours result in the strong aesthetic appeal.
  • The roof consists of turbo ventilators that are self-rotating and provided at the top of a roof. These turbo ventilators throw out the hot air and keep building fully ventilated.
  • The possibility of a bird building their nest is eliminated as there is no truss to support their nest. Thus it helps to provide cleaner and hygienic building environments.
  • For the natural lighting, roof sheet can be fitted with 1mm to 2mm thick transparent polycarbonate sheets in the designed length and spacing.
  • Up to 50% saving in cost as compared to conventional roofing system with truss and sheet.
  • It facilitates larger enclosed volumes allowing free movement & effective handling of goods and higher flexibility in space utilisation.
