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 animals and weather, rain or snow notably, but also heat, wind and sunlight. The word denotes the framing or framework which supports that covering also.[1]The characteristics of the roof are dependent upon the purpose of the building so it includes, the available roofing materials and the neighborhood traditions of development and wider ideas of architectural design and practice and may also be governed by local or nationwide legislation. In most countries a roof protects primarily against rain. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of the garden conservatory protects plants from cold, wind, and rain, but admits light.

In many parts of the planet ceramic tiles have been the predominant roofer materials for years and years, if not millennia. Other roofer materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon fabric, TPO, and wood shakes and shingles.
The construction of your roof is determined by its approach to support and the way the underneath space is bridged and set up roof is pitched. The pitch is the angle of which the roof rises from its least expensive to highest point. Most US domestic structures, except in very dry out locations, has roofs that are sloped, or pitched. Although modern building elements such as drainpipes might take away the dependence on pitch, roofs are pitched for reasons of looks and custom. So the pitch is dependent after stylistic factors partly, and partially regarding practicalities.
Some types of roofing, for example thatch, need a steep pitch to become durable and waterproof. Other styles of roofing, for example pantiles, are unstable on the steeply pitched roof but provide excellent weather protection at a relatively low angle. In parts where there is little rainfall, an almost flat roof with hook run-off provides enough protection against an occasional downpour. Drainpipes take away the need for a sloping roof structure also.
Somebody who specializes in roof construction is called a roofer.The durability of any roof is a subject of matter because the roof is usually the least accessible part of your building for purposes of repair and renewal, while its devastation or harm can have serious effects.
Because the purpose of a roofing is to safeguard people and their possessions from climatic elements, the insulating properties of any rooftop are a factor in its composition and the decision of roofing material.Some roof materials, particularly those of natural fibrous material, such as thatch, have excellent insulating properties. For all those that not, extra insulation is often installed under the external covering. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The purpose of a ceiling is to insulate against temperature and cold, noises, dirt and grime and often from the lice and droppings of birds who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed departing a space between the tiles and the roof covering surface, it can reduce home heating caused by the sun.Types of insulation are plastic or felt sheeting, sometimes with a reflective surface, installed below the tiles or other materials immediately; synthetic foam batting laid above the ceiling and recycled paper products and other such materials that can be inserted or sprayed into roof cavities. So called Cool roofs have become more and more popular, and occasionally are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly covered and ventilated roof covering can suffer from problems including the formation of ice dams throughout the overhanging eaves in cold weather, causing water from melted snow on higher elements of the rooftop to permeate the roofing materials. Ice dams take place when temperature escapes through the uppermost area of the roof, and the snow at those true factors melts, refreezing as it drips along the shingles, and collecting by means of ice at the lower points. This may bring about structural harm from stress, including the damage of gutter and drainage systems.
