Some materials in the roof assembly may require venting of the steel roof deck such as roof systems with light weight insulating concrete.
Roof deck assembly.
Loadmaster is an engineered roof deck system composed of a high tensile steel sections with thermal insulation and high performance duraflex mineral board mechanically anchored to the steel sections with engineered attachments to provide structural composite strength.
Grade c d or sheathing.
Roof decks with roof coverings in general occupied roof space with structure above is used for assembly occupancy a 2 and will be considered a story per the definition of a story see above.
Typically laid directly over roof membranes on smaller areas as a do it yourself option these 12 x 12 or 12 x 24 modular tiles offer a quick and easy rooftop deck flooring solution by simply snapping together each tile automatically aligned and precisely spaced thanks to the connecting tabs on the integral plastic base.

Hot mopped or cold application class a b or c covering or single ply membrane ballasted adhered or mechanically attached to the insulation.
Considering a roof deck as a story may be acceptable when the height of the deck does not exceed 2 3 stories depending on the construction type and whether or not sprinklers are used.
Venting does not impact the structural performance of the steel deck.
With no limit on max.
Through the use of engineered and tested structural composite action the roof deck provides outstanding gravity load capacity wind uplift resistance and diaphragm shear strength which stabilizes the building under wind and.
