A roof top is part of any building envelope. It is the covering on the uppermost part of a building or shelter which provides protection from family pets and weather, notably rain or snow, but heat also, sunlight and wind. The term denotes the framing or framework which supports that covering also.[1]The characteristics of an roof are centered upon the goal of the building that it covers, the available roof covering materials and the local traditions of construction and wider ideas of architectural design and practice and may also be governed by local or national legislation. In most countries a roof protects generally against rain. A verandah might be roofed with material that helps to protect against sunlight 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 entire world 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 cloth, TPO, and solid wood shingles and shakes.
The construction of an roof depends upon its approach to support and the way the underneath space is bridged and whether or not the roof is pitched. The pitch is the perspective of which the roof rises from its most affordable to highest point. Most US home structures, except in very dried out parts, has roofs that are sloped, or pitched. Although modern construction elements such as drainpipes might remove the dependence on pitch, roofs are pitched for reasons of looks and traditions. So the pitch is dependent upon stylistic factors partly, and to do with practicalities partly.
Some types of roofing, for example thatch, require a steep pitch to become waterproof and durable. Other styles of roofing, for example pantiles, are unstable on a steeply pitched roof but provide excellent weather protection at a relatively low angle. In areas where there is little rain, an almost toned roof with hook run-off provides sufficient protection against an occasional downpour. Drainpipes remove the dependence on a sloping roof structure also.
Somebody who specializes in roofing construction is called a roofer.The durability of the roof structure is a matter of matter because the roofing is usually the least accessible part of the building for purposes of repair and renewal, while its devastation or harm can have serious effects.
Because the reason for a roof top is to safeguard people and their belongings from climatic elements, the insulating properties of any rooftop are a awareness in its structure and the decision of roofing material.Some roof materials, those of natural fibrous materials especially, such as thatch, have excellent insulating properties. For all those that not, extra insulation is installed under the external covering often. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The purpose of a ceiling is to insulate against warmth and cold, noise, dirt and grime and frequently from the droppings and lice of parrots who frequently choose roofs as nesting places.
Concrete tiles can be utilized as insulation. When installed leaving a space between your tiles and the roof top surface, it can reduce heating system caused by the sun.Forms of insulation are sensed or clear plastic sheeting, sometimes with a reflective surface, installed directly 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 progressively popular, and in some cases are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly covered and ventilated roofer can suffer from problems like the formation of snow dams throughout the overhanging eaves in cold weather, causing water from melted snow on upper parts of the roof structure to permeate the roofing material. Ice dams happen when high temperature escapes through the uppermost part of the roof, and the snow at those points melts, refreezing as it drips across the shingles, and collecting in the form of ice at the low points. This may bring about structural harm from stress, including the devastation of drainage and gutter systems.
