A roof top is part of a building envelope. It is the covering on the uppermost part of the building or shelter which provides protection from animals and weather, rain or snow notably, but heat also, wind and sunlight. The word also denotes the framing or structure which supports that covering.[1]The characteristics of a roof are reliant upon the purpose of the building which it covers, the available roof materials and the local traditions of construction and wider ideas of architectural design and practice and may also be governed by local or countrywide legislation. In most countries a roof protects against rain primarily. A verandah might be roofed with materials that protects against natural light 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 entire world ceramic tiles have been the predominant roof covering materials for centuries, 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 roof structure is pitched. The pitch is the viewpoint of which the roof increases from its least expensive to highest point. Most US domestic structures, except in very dried up areas, has roofs that are sloped, or pitched. Although modern construction elements such as drainpipes might take away the need for pitch, roofs are pitched for reasons of custom and aesthetics. So the pitch is partly dependent after stylistic factors, and to do with practicalities partially.
Some types of roof covering, for example thatch, require 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 comparatively low angle. In locations where there is little rainfall, an almost flat roof with hook run-off provides sufficient protection against an occasional downpour. Drainpipes remove the dependence on a sloping roof top also.
A person that specializes in roof construction is named a roofer.The durability of your roof covering is a matter of matter because the roof structure is often the least accessible part of a building for purposes of repair and renewal, while its harm or devastation can have serious effects.
Because the purpose of a roof is to protect people and their possessions from climatic elements, the insulating properties of any roofing are a awareness in its framework and the decision of roofing material.Some roofer materials, specifically those of natural fibrous material, such as thatch, have excellent insulating properties. For those that not, extra insulation is installed under the outside part 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 warmth and cold, noises, dirt 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 the tiles and the roof structure surface, it can reduce heating system caused by the sun.Types of insulation are plastic or felt sheeting, with a reflective surface sometimes, installed immediately below the tiles or other material; 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 have become popular increasingly, and sometimes are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly covered and ventilated roofing can have problems with problems including the formation of ice dams throughout the overhanging eaves in winter, causing normal water from melted snow on top parts of the rooftop to permeate the roofing material. Ice dams arise when heat escapes through the uppermost part of the roof, and the snow at those tips melts, refreezing as it drips along the shingles, and collecting by means of ice at the lower points. This can cause structural harm from stress, including the destruction of gutter and drainage systems.
