A roof is part of a building envelope. It is the covering on the uppermost part of the building or shelter which gives protection from pets or animals and weather, rain or snow notably, but also heat, wind and sunlight. The word also denotes the framing or structure which supports that covering.[1]The characteristics of any roof are based mostly upon the purpose of the building so it addresses, the available roof covering materials and the local traditions of engineering and wider ideas of architectural design and practice and could also be governed by local or countrywide legislation. In most countries a roof protects against rain primarily. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of an garden conservatory protects plants from cold, wind, and rain, but admits light.

In many parts of the earth ceramic tiles have been the predominant roofing material for centuries, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, reboundable foam, PVC, slate, Teflon textile, TPO, and lumber shingles and shakes.
The construction of your roof is determined by its approach to support and how the underneath space is bridged and whether or not the roof structure is pitched. The pitch is the viewpoint at which the roof goes up from its lowest to highest point. Most US local structures, except in very dried out areas, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes may remove the need for pitch, roofs are pitched for reasons of appearance and traditions. So the pitch is partly dependent after stylistic factors, and partially regarding practicalities.
Some types of roofer, for example thatch, require a steep pitch to become durable and waterproof. Other types of roofing, for example pantiles, are unstable over a steeply pitched roof but provide excellent weather protection at a relatively low angle. In regions where there is little rainwater, an almost even roof with a slight run-off provides sufficient protection against an occasional downpour. Drainpipes also take away the need for a sloping roof structure.
A person that specializes in rooftop construction is called a roofer.The durability of a roof is a matter of matter because the roof covering is often the least accessible part of any building for purposes of repair and renewal, while its damage or damage can have serious effects.
Because the purpose of a roofing is to protect people and their belongings from climatic elements, the insulating properties of your roofing are a thought in its composition and the decision of roofing material.Some roof covering materials, particularly those of natural fibrous materials, such as thatch, have excellent insulating properties. For those that not, extra insulation is often installed under the outer covering. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The goal of a roof is to insulate against high temperature and cold, noise, dirt and frequently from the lice and droppings of wild birds who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed going out of a space between the tiles and the roof surface, it can reduce heat caused by the sun.Types of insulation are felt or clear plastic sheeting, with a reflective surface sometimes, installed below the tiles or other materials directly; synthetic foam batting laid above the ceiling and recycled paper products and other such materials that may be inserted or sprayed into roof cavities. So called Cool roofs are becoming progressively more popular, and in some full cases are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly insulated and ventilated roof can have problems with problems including the formation of snow dams round the overhanging eaves in cold weather, causing water from melted snow on higher parts of the rooftop to penetrate the roofing materials. Ice dams arise when warmth escapes through the uppermost area of the roof, and the snow at those true points melts, refreezing as it drips along the shingles, and collecting in the form of ice at the low points. This may bring about structural destruction from stress, like the destruction of drainage and gutter systems.
