List of roof shapes
The shape of roofs differs greatly from region to region. The main factors which influence the shape of roofs are the climate and the materials available for roof structure and the outer covering.
Roofs vary from almost flat to steeply pitched. They can be arched or dome. They can be a single flat sheet or a complex arrangement of slopes, gables and hips.
[1]==Roof shapes==
- Flat roofs are found in the traditional buildings in regions with a low precipitation, but modern materials which are highly impermeable to water make possible the very large roofs of low pitch that are found on large commercial buildings.
- Terrace - a flat roof with balustrade, used as a living space
- Skillion roof single-sloped or shed roof
- Saw-tooth - a roof comprising a series of skillion roofs with vertical surfaces glazed and facing away from the equator. The sloping surfaces are opaque, shielding the workers and machinery from direct sunlight. This sort of roof admits natural light into a factory.Also known as 'Northlight' in the northern hemisphere.[2]
- Pitched, peaked, or gabled
- Hip roof
- Mansard – with the pitch divided into a shallow slope above a steeper slope
- Gambrel – as a mansard, but on only two sides of the roof
- Bell-cast – as a mansard, but with the shallow slope below the steeper slope
- Pyramidal
- Pyatthat
- Tented roof
- Helm Roof - Rhenish helm - a pyramidal roof with gable ends found on church towers
- Arched roof
- Circular
