A roof covering is part of a building envelope. It's the covering on the uppermost part of any building or shelter which gives protection from animals and weather, rain or snow notably, but heat also, sunlight and wind. The term denotes the framing or structure which facilitates that covering also.[1]The characteristics of a roof are dependent upon the goal of the building that it covers, the available roofing materials and the local traditions of construction 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 might be roofed with material that helps to protect against sunshine but admits the other elements. The roof of a garden conservatory protects plants from cold, wind, and rain, but admits light.

In many elements of the global world ceramic tiles have been the predominant roof material for centuries, if not millennia. Other roofer materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon fabric, TPO, and lumber shakes and shingles.
The construction of your roof depends upon its method of support and the way the underneath space is bridged and set up roof structure is pitched. The pitch is the viewpoint at which the roof increases from its lowest to highest point. Most US home architecture, except in very dry parts, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes might take away the dependence on pitch, roofs are pitched for reasons of traditions and aesthetics. So the pitch is partly dependent after stylistic factors, and partially to do with practicalities.
Some types of roofer, for example thatch, need a steep pitch in order to be durable and waterproof. Other types of roofing, for example pantiles, are unstable on the steeply pitched roof but provide excellent weather protection at a comparatively low angle. In locations where there is little rain, an almost chiseled roof with hook run-off provides enough protection against an intermittent downpour. Drainpipes take away the dependence on a sloping roof structure also.
A person that specializes in roof structure construction is called a roofer.The durability of a roofing is a matter of matter because the roof structure is usually the least accessible part of the building for purposes of repair and renewal, while its damage or devastation can have serious effects.
Because the reason for a roof top is to safeguard people and their property from climatic elements, the insulating properties of a roof are a awareness in its framework and the decision of roofing material.Some roof materials, particularly those of natural fibrous material, such as thatch, have excellent insulating properties. For those that do not, extra insulation is installed under the outside covering often. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The goal of a roof is to insulate against temperature and cold, noises, dirt and grime and often from the lice and droppings of parrots who frequently choose roofs as nesting places.
Cement tiles can be utilized as insulation. When installed leaving a space between your tiles and the roof covering surface, it can reduce heating system caused by sunlight.Types of insulation are vinyl or sensed 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 significantly popular, and in some cases are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly protected and ventilated roof can suffer from problems such as the formation of snow dams surrounding the overhanging eaves in winter, causing drinking water from melted snow on top parts of the rooftop to penetrate the roofing material. Ice dams take place when warmth escapes through the uppermost part 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 low points. This may result in structural damage from stress, like the destruction of gutter and drainage systems.
