A rooftop is part of a 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, sunlight and wind. The word denotes the framing or composition which supports that covering also.[1]The characteristics of the roof are reliant upon the purpose of the building which it covers, the available roof covering materials and the local traditions of structure and wider ideas of architectural design and practice and could also be governed by local or countrywide legislation. In most countries a roof protects against rain primarily. A verandah may 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 lots of elements of the global world ceramic tiles have been the predominant roofer materials for centuries, if not millennia. Other roofer materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, reboundable foam, PVC, slate, Teflon fabric, TPO, and solid wood shingles and shakes.
The construction of a roof is determined by its approach to support and the way the underneath space is bridged and whether or not the rooftop is pitched. The pitch is the perspective of which the roof goes up from its most affordable to highest point. Most US local structures, except in very dry out areas, has roofs that are sloped, or pitched. Although modern building elements such as drainpipes might take away the need for pitch, roofs are pitched for reasons of tradition and looks. So the pitch is dependent after stylistic factors partly, and to do with practicalities partially.
Some types of roofer, for example thatch, require a steep pitch to become waterproof and durable. Other types of roofing, for example pantiles, are unstable over a steeply pitched roof but provide excellent weather protection at a comparatively low angle. In locations where there is little rainfall, an almost chiseled roof with hook run-off provides adequate protection against an intermittent downpour. Drainpipes also remove the dependence on a sloping roofing.
Somebody who specializes in roof structure construction is called a roofer.The durability of a roofing is a subject of matter because the roof structure is often the least accessible part of the building for purposes of repair and renewal, while its destruction or destruction can have serious effects.
Because the purpose of a rooftop is to safeguard people and their possessions from climatic elements, the insulating properties of an roof are a concern in its structure and the choice of roofing material.Some roofer materials, those of natural fibrous material especially, such as thatch, have excellent insulating properties. For those that do not, extra insulation is often installed under the outside coating. 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 warmth and cold, noises, dirt and grime and often from the droppings and lice of wild birds who frequently choose roofs as nesting places.
Cement tiles can be used as insulation. When installed going out of a space between the tiles and the roofing surface, it can reduce heating caused by sunlight.Types of insulation are plastic or noticed sheeting, sometimes with a reflective surface, installed below the tiles or other materials immediately; 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 significantly 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 roof can suffer from problems like the formation of glaciers dams throughout the overhanging eaves in winter, causing drinking water from melted snow on upper elements of the roof structure to permeate the roofing materials. Ice dams occur when heating escapes through the uppermost area of the roof, and the snow at those true points melts, refreezing as it drips along the shingles, and collecting by means of ice at the low points. This can lead to structural damage from stress, including the devastation of gutter and drainage systems.
