What is Metal Roofing?
A metal roof is a roofing system made from metal pieces or tiles characterized by its high resistance, impermeability and longevity. It is a component of the building envelope. Zinc, copper and steel alloys are commonly used.
Purlins
- Prior to the installation of roofing sheeting, purlins must be orientated correctly and on the correct side of the cleats.
Safety Mesh
- Refer to the section Safety Mesh of the Health and Safety Handbook
- Sheeting must be lapped in the right direction with regard to ‘over’ versus ‘under’ i.e. the side lap is to face away from prevailing weather.
