A roof structure is part of any building envelope. It is the covering on the uppermost part of a building or shelter which gives protection from animals and weather, notably rain or snow, but heat also, sunlight and wind. The word denotes the framing or structure which supports that covering also.[1]The characteristics of any roof are dependent upon the purpose of the building that this addresses, the available roofer materials and the local traditions of development and wider principles 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 materials that shields against sunshine but admits the other elements. The roof of any garden conservatory protects plants from cold, wind, and rain, but admits light.

In lots of parts of the planet ceramic tiles have been the predominant roofing materials for centuries, if not millennia. Other roof covering materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, polyurethane 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 top is pitched. The pitch is the viewpoint of which the roof goes up from its most affordable to highest point. Most US domestic architecture, except in very dry parts, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes might take away the need for pitch, roofs are pitched for reasons of looks and custom. 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 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 regions where there is little rain, an almost chiseled roof with a slight run-off provides sufficient protection against an intermittent downpour. Drainpipes remove the need for a sloping roof top also.
A person that specializes in roof top construction is named a roofer.The durability of the roof is a subject of concern because the rooftop is often the least accessible part of the building for purposes of repair and renewal, while its destruction or devastation can have serious results.
Because the reason for a roof is to protect people and their belongings from climatic elements, the insulating properties of a roof top are a concern in its structure and the decision of roofing material.Some roofer materials, those of natural fibrous materials particularly, such as thatch, have excellent insulating properties. For those that do not, extra insulation is often installed under the exterior level. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The goal of a ceiling is to insulate against high temperature and cold, sound, dirt and grime and frequently from the lice and droppings of birds who frequently choose roofs as nesting places.
Cement tiles can be used as insulation. When installed departing a space between the tiles and the roof covering surface, it can reduce heating system caused by the sun.Forms of insulation are clear plastic or noticed sheeting, sometimes with a reflective surface, 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 are becoming ever more popular, and in some full cases 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 have problems with problems such as the formation of ice dams round the overhanging eaves in winter, causing water from melted snow on higher elements of the roof top to permeate the roofing material. Ice dams happen when warmth escapes through the uppermost area of the roof, and the snow at those things melts, refreezing as it drips along the shingles, and collecting by means of ice at the lower points. This may result in structural harm from stress, including the destruction of gutter and drainage systems.
