A roof is the uppermost part of a building and is used to cover the interior of your home or a roof that protects the building and its elements from the elements of weather (such as effects caused by rain, sunlight, wind, cold, heat, snow etc.). Roofs can be in any structures that range from a letter box to a cathedral or stadium, dwellings, flat etc.
The features of a roof depend on the purpose of the building that it covers, roofing materials and the local traditions of construction and wider concepts of architectural design.
There are many types of roofs available such as mansard roof, gambrel roof, gable roof, cross gabled roof, hip roof, pyramid hip roof, cross hipped roof, saltbox roof, flat roof, bonnet roof, shed roof, arched roof, Skillion roof etc.
Mansard roof is made up of four slopes, two on each side of the home. The lower slope is a steeper, more vertical slope than the upper slope. The upper slope may or may not be visible from the ground. This roof allows additional living space or storage space at the top of the house. This is French inspired home.
Gambrel roof is similar to the mansard roof but the two slopes are present only at two sides of roof instead of four. And it is Dutch inspired home instead of French.
Saltbox roof looks interesting from the exterior. It is an asymmetrical long pitched roof with one side very less height and other side with long height.
Pyramid shaped roofs do not have flat sides and this is suitable for high wind or hurricane areas.
