The roofs are fundamental element in the enclosure of the building. There are various
types of roofs from flat to pitched. All of them need to function as a means to keep
the rain, wind and snow out of the building. Often roofs are used by architects
as a way of defining the unique nature of the building to be constructed. They can
be designed to articulate the current fashion and trends, or built to emulate some
past historical period. The finishes to the roofs are an important aesthetic choice
and can show a value to the architectural outcome. Materials used for the finishes
to the roofs are very much dependent on the pitch of the roof required.
