A roof top is part of an building envelope. It's the covering on the uppermost part of an building or shelter which provides protection from family pets and weather, rain or snow notably, but also heat, wind and sunlight. The term also denotes the framing or structure which supports that covering.[1]The characteristics of your roof are dependent upon the goal of the building it protects, the available roofing materials and the local traditions of construction and wider principles of architectural design and practice and may also be governed by local or nationwide legislation. In most countries a roof protects primarily against rain. A verandah might be roofed with material that helps to protect 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 global world ceramic tiles have been the predominant roof covering materials for centuries, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, polyurethane foam, PVC, slate, Teflon cloth, TPO, and hardwood shakes and shingles.
The construction of a roof is determined by its method of support and the way the underneath space is bridged and whether or not the roof is pitched. The pitch is the position of which the roof goes up from its least expensive to highest point. Most US local architecture, except in very dried out parts, has roofs that are sloped, or pitched. Although modern engineering elements such as drainpipes might take away the dependence on pitch, roofs are pitched for reasons of looks and custom. So the pitch is dependent after stylistic factors partly, and partially to do with practicalities.
Some types of roofing, for example thatch, require a steep pitch to become waterproof and durable. Other types 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 rain, an almost level roof with a slight run-off provides sufficient protection against an occasional downpour. Drainpipes also remove the dependence on a sloping roof top.
A person that specializes in roof construction is named a roofer.The durability of an rooftop is a subject of matter because the roof top is usually the least accessible part of an building for purposes of repair and renewal, while its damage or damage 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 roof are a factor in its composition and the choice of roofing material.Some roofer materials, those of natural fibrous materials especially, such as thatch, have excellent insulating properties. For those that not, extra insulation is often installed under the outside covering. 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 often from the lice and droppings of birds who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed giving a space between the tiles and the rooftop surface, it can reduce heat caused by the sun.Types of insulation are vinyl or thought 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 have become progressively popular, and occasionally are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly insulated and ventilated roofing can suffer from problems like the formation of snow dams around the overhanging eaves in winter, causing normal water from melted snow on higher parts of the roofing to penetrate the roofing materials. Ice dams take place when high temperature escapes through the uppermost part of the roof, and the snow at those true points melts, refreezing as it drips over the shingles, and collecting by means of ice at the lower points. This can cause structural damage from stress, like the devastation of drainage and gutter systems.
