ROOFS
Roof
is a horizontal or sloping structural member provided as a cover to a building.
intermediate floors are covered by horizontal R.C.C. slabs.
1. REQUIREMENTS OF A GOOD ROOF
1.
Protective Covering: A roof should give a cover to the
building by protecting it from ill effects of natural agencies like sun shine,
rain, wind, dust and snow. 2.
2.
Durability: Roof should be made of durable materials
to withstand the adverse effects of sun, wind, rain, dust and snow.
3.
Draining the Rain Water: Roof should have adequate slope to
drain-off the rain water in the simplest and direct manners.
4.
Structural Stability: Roof should be structurally stable. It
should be strong enough to carry the loads coming on it.
5.
Water-Proof: Roof should prevent dampness under the
roof. It should be water-proof.
6.
Insulation from Heat and Sound: Roof should provide
insulation from heat and sound.
7.
Appearance: Roof should have an aesthetically
pleasing and architectural appearance.
8.
Fire-Resistant: Roof should be fire-resistant.
9.
Strength of Roof Covering: Roof covering should be strong
enough to withstand its own weight and of workmen who may occasionally climb up
for maintenance.
2. TYPES OF ROOFS
The
roofs are classified according to shape, span and structural design principles
as follows:
*
Flat Roofs or Terrace Roofs
*
Sloping or Pitched Roofs
*
Curved Roofs
