How to install colorbond roofing sheets.
Position your sheets on the ground before raising to the roof for laying.
The cost of colorbond roofing will depend on the design and scale.
Aside from the installation and other labour costs colorbond roofing is set at a reasonable price because it is more than just a metal roofing system.
The overlapping sheet edges should be raised facing the direction of installation i e positioned the same way as the other sheets.
The edges of the roofing sheets are normally pre shaped to prevent moisture from being sucked into the overlapping areas by a capillary action too so in most cases only one overlap is recommended between the sheets.
It s also very important for the installer to ensure that the roofing sheets align.
