A roof structure is part of a building envelope. It is the covering on the uppermost part of an building or shelter which provides protection from pets and weather, notably rain or snow, but heat also, sunlight and wind. The word also denotes the framing or structure which supports that covering.[1]The characteristics of a roof are reliant upon the goal of the building that it protects, the available roof covering materials and the local traditions of engineering and wider concepts of architectural design and practice and could also be governed by local or countrywide legislation. In most countries a roof protects primarily against rain. A verandah might be roofed with material that shields against sun rays 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 globe ceramic tiles have been the predominant roofing material for centuries, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon fabric, TPO, and solid wood shakes and shingles.
The construction of your roof is determined by its method of support and how the underneath space is bridged and whether or not the roof structure is pitched. The pitch is the position of which the roof increases from its most affordable to highest point. Most US home structures, except in very dried out locations, has roofs that are sloped, or pitched. Although modern development elements such as drainpipes may remove the need for pitch, roofs are pitched for reasons of appearance and tradition. So the pitch is partly dependent upon stylistic factors, and partially regarding practicalities.
Some types of roof covering, for example thatch, require a steep pitch in order to be waterproof and durable. Other styles of roofing, for example pantiles, are unstable on a steeply pitched roof but provide excellent weather protection at a comparatively low angle. In areas where there is little rain, an almost flat roof with hook run-off provides sufficient protection against an occasional downpour. Drainpipes also remove the dependence on a sloping roofing.
Somebody who specializes in rooftop construction is called a roofer.The durability of an roof top is a subject of concern because the rooftop is usually the least accessible part of any building for purposes of repair and renewal, while its damage or harm can have serious results.
Because the purpose of a rooftop is to safeguard people and their possessions from climatic elements, the insulating properties of an rooftop are a thought in its structure and the decision of roofing material.Some roof materials, specifically those of natural fibrous material, such as thatch, have excellent insulating properties. For all those that do not, extra insulation is installed under the external level often. 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 heat and cold, noise, dirt and grime and often from the lice and droppings of parrots who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed leaving a space between the tiles and the roofing surface, it can reduce heating up caused by sunlight.Types of insulation are plastic material or sensed sheeting, with a reflective surface sometimes, installed straight 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 popular progressively more, 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 protected and ventilated roof covering can have problems with problems such as the formation of snow dams across the overhanging eaves in cold weather, causing drinking water from melted snow on top parts of the roof structure to penetrate the roofing materials. Ice dams occur when warmth escapes through the uppermost area of the roof, and the snow at those things melts, refreezing as it drips over the shingles, and collecting by means of ice at the lower points. This may cause structural harm from stress, like the damage of gutter and drainage systems.
