Shell roof may be defined as a folded plate roof surface, the thickness of which is small compared to the other dimensions. In these roofs lot of load is transferred by membrane compression instead of by bending as in the case of conventional slab and beam constructions.
Caves are having natural shell roofs.

Advantages folded plate roof Disadvantages of Shell Roofs Advantages of shell roofs are: Folded plate roofs may be looked as slab with a number of folds.
These roofs are also known as hipped folded plate roof, prismatic shells and faltwerke. In these structures also bending is reduced and lot of load gets transferred as membrane compression. However folded plates are not so efficient as shells.
Roof Coverings for Pitched Roofs Various types of covering materials are available for pitched roofs and their selection depends upon the climatic conditions, fabrication facility, availability of materials and affordability of the owner.
Commonly used pitched folded plate roof covering materials are: These coverings are provided for small spans, mainly for residential buildings in villages.
Thatch is a roof covering of straw, reeds or similar materials. The thatch is well-soaked in water or fire resisting solution and packed bundles are laid with their butt ends folded plate roof towards eves.

Thickness varies from mm to mm. They are tied with ropes or twines to supporting structures. The folded plate roof structure consists of round bamboo rafters spaced at mm to mm over which split bamboos laid at right angles at close spacing.
It is claimed that reed thatch can last 50 to 60 years while straw thatch may last for 20—25 years. The folded plate roof of thatch roof is they are cheap and do not need skilled workers to build them.

The disadvantages are they are very poor fire resistant and harbour rats and other insects. Wood shingles are nothing but folded plate roof split or sawn thin pieces of wood.
Their size varies from mm to mm and length from 60 mm to mm. Their thickness varies from 10 mm at one end to 3 mm at the other end.
They are nailed to supporting structures.

They are commonly used folded plate roof hilly areas for low cost housing. They have very poor fire and termite resistance. Various clay tiles are manufactured in different localities. They serve as good covering materials.
And resolving the load at any ridge in the directions of two adjoining plates, one can get the forces p2,1, p2,3, p3,4, ….
