A rooftop is part of an building envelope. It's the covering on the uppermost part of an building or shelter which gives protection from family pets and weather, notably rain or snow, but also heat, wind and sunlight. The term denotes the framing or framework which helps that covering also.[1]The characteristics of a roof are reliant upon the purpose of the building that this addresses, the available roof materials and the local traditions of building and wider concepts of architectural design and practice and could 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 protects against sunlight but admits the other elements. The roof of the garden conservatory protects plants from cold, wind, and rain, but admits light.

In many elements of the global world ceramic tiles have been the predominant roof covering material for centuries, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, polyurethane foam, PVC, slate, Teflon textile, TPO, and real wood shakes and shingles.
The construction of a roof depends upon its approach to support and the way the underneath space is bridged and whether or not the roof structure is pitched. The pitch is the viewpoint of which the roof rises from its least expensive to highest point. Most US home architecture, except in very dried out parts, has roofs that are sloped, or pitched. Although modern construction elements such as drainpipes may take away the need for pitch, roofs are pitched for reasons of traditions and aesthetics. So the pitch is dependent after stylistic factors partly, and to do with practicalities partly.
Some types of roofer, for example thatch, need 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 relatively low angle. In areas where there is little rainwater, an almost level roof with a slight run-off provides adequate protection against an occasional downpour. Drainpipes also take away the need for a sloping roof.
Somebody who specializes in roofing construction is called a roofer.The durability of your roof top is a subject of matter because the roof is usually the least accessible part of an building for purposes of repair and renewal, while its destruction or damage can have serious effects.
Because the reason for a roof is to safeguard people and their belongings from climatic elements, the insulating properties of your roof structure are a account in its framework and the decision of roofing material.Some roofing materials, those of natural fibrous materials specifically, such as thatch, have excellent insulating properties. For all those that not, extra insulation is installed under the external part 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 heat and cold, noise, mud and frequently from the droppings and lice of birds who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed giving a space between your tiles and the roofing surface, it can reduce heating caused by sunlight.Forms of insulation are plastic or sensed 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 can be inserted or sprayed into roof cavities. So called Cool roofs have become more and 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 protected and ventilated roofer can have problems with problems such as the formation of ice dams around the overhanging eaves in winter, causing drinking water from melted snow on higher parts of the roof structure to permeate the roofing material. Ice dams occur when temperature escapes through the uppermost part of the roof, and the snow at those true tips melts, refreezing as it drips along the shingles, and collecting by means of ice at the low points. This can lead to structural destruction from stress, including the damage of gutter and drainage systems.
