Dead Loads

Any permanent load added to the roof cladding or structure is termed imposed; that includes air-conditioning equipment, solar installations, television aerials, anchor points, and walkways.

All loads must be supported on the rib of the profile or through the profile to the primary structure. Any attachment to the roof cladding must be compatible with the cladding, or isolated from it.

 

Correctly Installed Permanent Load

An air conditioning unit correctly installed on a roof, using durable and compatible materials.
No additional equipment must be directly connected to the cladding without considering the effect of increased dead and live loads.
When designing installations for placement on the roof, the roof traffic implications of installing and servicing such must be considered when determining point load resistance requirements.
