A roofing is part of your building envelope. It is the covering on the uppermost part of a building or shelter which provides protection from pets and weather, rain or snow notably, but heat also, sunlight and wind. The term denotes the framing or framework which facilitates that covering also.[1]The characteristics of the roof are dependent upon the purpose of the building so it covers, the available roof materials and the local traditions of building and wider principles of architectural design and practice and may also be governed by local or nationwide legislation. In most countries a roof protects mainly against rain. 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 lots of parts of the entire world ceramic tiles have been the predominant roof covering material for years and years, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, reboundable foam, PVC, slate, Teflon textile, TPO, and solid wood shakes and shingles.
The construction of your roof depends upon its method of support and how the underneath space is bridged and whether or not the roofing is pitched. The pitch is the angle of which the roof rises from its minimum to highest point. Most US local structures, except in very dried up areas, has roofs that are sloped, or pitched. Although modern engineering elements such as drainpipes may take away the need for pitch, roofs are pitched for reasons of looks and traditions. So the pitch is dependent upon stylistic factors partly, and partially to do with practicalities.
Some types of roofing, for example thatch, need a steep pitch in order to be waterproof and durable. 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 areas where there is little rainwater, an almost smooth roof with hook run-off provides enough protection against an intermittent downpour. Drainpipes remove the need for a sloping rooftop also.
A person that specializes in roofing construction is called a roofer.The durability of a roofing is a subject of concern because the roof structure is usually the least accessible part of any building for purposes of repair and renewal, while its destruction or harm can have serious effects.
Because the reason for a roof structure is to safeguard people and their possessions from climatic elements, the insulating properties of any rooftop are a awareness in its composition and the decision of roofing materials.Some roof materials, those of natural fibrous materials specifically, such as thatch, have excellent insulating properties. For those that not, extra insulation is installed under the outside level often. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The purpose of a roof is to insulate against high temperature and cold, sound, mud and frequently from the lice and droppings of birds who frequently choose roofs as nesting places.
Concrete tiles can be utilized as insulation. When installed departing a space between the tiles and the roof structure surface, it can reduce heating system caused by sunlight.Types of insulation are felt or clear plastic sheeting, with a reflective surface sometimes, installed below the tiles or other material 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 instances 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 have problems with problems including the formation of glaciers dams across the overhanging eaves in cold weather, causing water from melted snow on higher elements of the roofing to permeate the roofing material. Ice dams take place when high temperature escapes through the uppermost area of the roof, and the snow at those true tips melts, refreezing as it drips along the shingles, and collecting by means of ice at the low points. This can cause structural destruction from stress, including the damage of gutter and drainage systems.
