A roof top 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, notably rain or snow, but also heat, sunlight and wind. The word denotes the framing or composition which facilitates that covering also.[1]The characteristics of your roof are based mostly upon the purpose of the building that this protects, the available roofing materials and the neighborhood traditions of engineering and wider principles of architectural design and practice and may also be governed by local or national 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 many parts of the planet ceramic tiles have been the predominant roofer materials for centuries, if not millennia. Other roof covering materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, reboundable foam, PVC, slate, Teflon cloth, TPO, and hardwood shingles and shakes.
The construction of any roof is determined by its approach to support and how the underneath space is bridged and whether or not the roof is pitched. The pitch is the position at which the roof rises from its lowest to highest point. Most US local structures, except in very dried up areas, has roofs that are sloped, or pitched. Although modern construction elements such as drainpipes might remove the need for pitch, roofs are pitched for reasons of traditions and aesthetics. So the pitch is dependent upon stylistic factors partly, and partially regarding practicalities.
Some types of roofer, 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 locations where there is little rain, an almost toned roof with hook run-off provides adequate protection against an occasional downpour. Drainpipes remove the dependence on a sloping roof top also.
Somebody who specializes in rooftop construction is called a roofer.The durability of a roof is a matter of concern because the roof top is often the least accessible part of your building for purposes of repair and renewal, while its damage or devastation can have serious results.
Because the purpose of a roof is to safeguard people and their belongings from climatic elements, the insulating properties of any rooftop are a awareness in its composition and the decision of roofing material.Some roofer materials, those of natural fibrous materials especially, such as thatch, have excellent insulating properties. For those that do not, extra insulation is often installed under the outer part. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The purpose of a roof is to insulate against heating and cold, sound, mud and often from the lice and droppings of wild birds who frequently choose roofs as nesting places.
Cement tiles can be used as insulation. When installed leaving a space between your tiles and the roofing surface, it can reduce heating system caused by the sun.Forms of insulation are sensed or cheap 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 popular more and more, and sometimes are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly protected and ventilated roof covering can have problems with problems like the formation of glaciers dams surrounding the overhanging eaves in winter, causing normal water from melted snow on higher elements of the roof structure to permeate the roofing materials. Ice dams take place when heating escapes through the uppermost area of the roof, and the snow at those points melts, refreezing as it drips along the shingles, and collecting in the form of ice at the lower points. This may cause structural harm from stress, including the destruction of drainage and gutter systems.
