A roof top is part of an building envelope. It's the covering on the uppermost part of your building or shelter which provides protection from pets and weather, rain or snow notably, but heat also, sunlight and wind. The term also denotes the framing or structure which supports that covering.[1]The characteristics of a roof are dependent upon the purpose of the building so it includes, the available roofing materials and the local traditions of development and wider concepts of architectural design and practice and may also be governed by local or nationwide legislation. In most countries a roof protects against rain primarily. A verandah might be roofed with material that defends against natural light 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 global world ceramic tiles have been the predominant roof covering material for years and years, if not millennia. Other roof materials include asphalt, coal tar pitch, EPDM rubber, Hypalon, polyurethane foam, PVC, slate, Teflon fabric, TPO, and real wood shakes and shingles.
The construction of any 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 at which the roof goes up from its minimum to highest point. Most US domestic architecture, except in very dry out regions, has roofs that are sloped, or pitched. Although modern construction elements such as drainpipes might take away the need for pitch, roofs are pitched for reasons of aesthetics and custom. So the pitch is partly dependent upon stylistic factors, and to do with practicalities partly.
Some types of roof covering, for example thatch, require a steep pitch in order to be durable and waterproof. 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 parts where there is little rainfall, an almost even roof with a slight run-off provides sufficient protection against an intermittent downpour. Drainpipes remove the need for a sloping roof also.
A person that specializes in rooftop construction is called a roofer.The durability of an roof top is a subject of concern because the roof top is usually the least accessible part of the building for purposes of repair and renewal, while its damage or damage can have serious results.
Because the purpose of a rooftop is to safeguard people and their belongings from climatic elements, the insulating properties of the rooftop are a account in its structure and the choice of roofing material.Some roof covering materials, those of natural fibrous materials specifically, such as thatch, have excellent insulating properties. For those that do not, extra insulation is installed under the external part often. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The purpose of a ceiling is to insulate against heat and cold, sound, dirt and frequently from the droppings and lice 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 caused by sunlight.Forms of insulation are plastic or believed sheeting, with a reflective surface sometimes, 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 have become popular significantly, 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 can have problems with problems including the formation of snow dams round the overhanging eaves in winter, causing water from melted snow on upper parts of the roof covering to penetrate the roofing materials. Ice dams happen when heating escapes through the uppermost area of the roof, and the snow at those true points melts, refreezing as it drips across the shingles, and collecting in the form of ice at the low points. This may result in structural damage from stress, including the destruction of drainage and gutter systems.
