Vegetation grown on top of a roof can offer insulation as well as protection to the roof membrane. Flooring materials used are often wood, flagstones or metal. Wood is the traditional look for your flooring or decking and however wood does require more maintenance other than other materials such as steel. Flagstones are common on commercial buildings, however the weight of these must be considered in the design process of the roof.

Common problems with roof decks:
