Presentation on types of Roofs in building construction
A roof may be defined as the uppermost part of the building, provided as a structural covering, to protect the building from weather (i.e. from rain,sun, wind, etc.).
Structurally, a roof is constructed in the same way as an upper floor, though the shape of its upper surface may be different.
Basically, a roof consists of structural elements which support roof coverings. The structural element may be trusses, portals, beams, slabs (with or without beams), shells or domes.
The roof coverings may be AC. sheets, G.I. sheets, wooden shingle, tiles, slates or slab itself.
Roof and roof coverings receive rain and snow more directly and in much greater quantity than do the walls. It must, therefore, provide a positive barrier to the entry of rain, and vigorous weather proofing is most important.
The roof structure, which support the roof coverings must have adequate strength and stability.
Apart from these, a roof must have thermal insulation, fire resistance and sound insulation.
Roofs may be divided into three categories :

Roofs may be divided into three categories :
- Pitched or sloping roofs
- Flat roofs or terraced roofs
- Curved roofs
