A rooftop is part of a 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 word denotes the framing or structure which supports that covering also.[1]The characteristics of a roof are dependent upon the goal of the building it protects, the available roof materials and the local traditions of building and wider ideas of architectural design and practice and could also be governed by local or nationwide 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 a 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 roofer materials for centuries, if not millennia. Other roof covering materials include asphalt, coal tar pitch, EPDM plastic, Hypalon, reboundable foam, PVC, slate, Teflon textile, TPO, and lumber shingles and shakes.
The construction of your roof depends upon its approach to support and the way the underneath space is bridged and set up roof covering is pitched. The pitch is the perspective of which the roof rises from its least expensive to highest point. Most US domestic architecture, except in very dried locations, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes may take away the need for pitch, roofs are pitched for reasons of tradition and appearance. So the pitch is dependent after stylistic factors partly, and to do with practicalities partly.
Some types of roof covering, for example thatch, need a steep pitch to become durable and waterproof. Other styles of roofing, for example pantiles, are unstable on a steeply pitched roof but provide excellent weather protection at a comparatively low angle. In areas where there is little rainfall, an almost even roof with a slight run-off provides sufficient protection against an occasional downpour. Drainpipes remove the dependence on a sloping roofing also.
A person that specializes in roofing construction is called a roofer.The durability of the roof covering is a subject of matter because the rooftop is often the least accessible part of an building for purposes of repair and renewal, while its devastation or destruction can have serious results.
Because the reason for a roof structure is to safeguard people and their belongings from climatic elements, the insulating properties of an roof top are a consideration in its framework and the decision of roofing material.Some roofer materials, especially those of natural fibrous material, such as thatch, have excellent insulating properties. For those that do not, extra insulation is often installed under the external layer. 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 warmth and cold, noises, mud and often from the droppings and lice of wild birds 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 structure surface, it can reduce home heating caused by sunlight.Types of insulation are thought 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 have become popular significantly, and sometimes are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly protected and ventilated roofing can have problems with problems including the formation of snow dams throughout 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 arise when heat escapes through the uppermost area of the roof, and the snow at those true details melts, refreezing as it drips across the shingles, and collecting in the form of ice at the low points. This may result in structural harm from stress, like the devastation of gutter and drainage systems.
