Flat roof coverings frequently used include sheet materials like bituminous felt. Materials used in situ, like asphalt, and metal, such as copper or lead.

The deck is the major part of the roof that forms the ’floor’ and provides shade to the house. Here are some of the common types of flat roof decks.

1. Flat concrete-slab roofs

A concrete slab typically consists of a concrete structural layer finished with a smooth screed, on top of which is put a waterproof layer, such as a membrane. Insulation and often a vapor control layer should be included in the roof to prevent interstitial condensation.

2. Flat wooden roofs

Construction of timber flat roofs typically comprises structural joists covered in plywood or other comparable sheet material decking. Joists should, if possible, span the roof plan’s shortest distance. The roof covering and the needed rate of rainfall discharge determine the pitch. Simple, efficient, and offers a way for natural cross ventilation, but requires more wood are joist-run fireplaces. The spacing and diameters of the joists needed will depend on the loads and span of the flat roof.
