The shed roofs are simple, single-sloping roofs. It reflects a better appearance of a building.

Think in your past if anyone told you to draw a house, you draw a gabled roof house. The gabled roof is a very famous roof.
Pitched Or Sloping Roof
A Pitched roofs have a higher sloping roof, due to higher sloping roofs the water easily runoff on the pitched roof.
The Pitched roofs are better for the area having more rains and snowfalls.

The curved roof is used for large areas and big structures like factories, monuments, libraries, etc.
The curved roof is an updated version of a pitched roof and it gives a good architectural effect.
The curve roof is good for any environment. It is constructed by using timber or metals.
The roof that has four sides slope and the four sides slopes come together and form a simple ridge, then this type of roof called Hip roofs.
The design of the hip roof makes it good for the area where the snowfall is more.
Flat Or Terraced Roof
A roof that is nearly flat is known as the flat or terraced roof and it has some slope.
The construction of the flat roof is same as the construction of the top surface except in a flat roof there is some slope is given.
The advantages of using a flat roof are, it is more stable against high wind, economical than a pitched roof, easily constructed, easy to make fireproof, etc.
The main disadvantages of using flat roofs are, cracks are developed due to variation in temperature, are not good for heavy rainfall areas, the initial cost is higher than a pitched roof, etc.
The roof has two slopes on each symmetrical side is known as the gambrel roof.
A gambrel roof is a modified version of the gable roof.
Gambrel roof provided a good space to create an attic room or loft at the uppermost part of the building.
A pyramid roof is a type of hip roof, having four sides in a triangular shape.
The pyramid roof is used in small structures like cabins, garages, bungalows, etc.
It provides extra space for ventilation and an attic room or loft.
