A roof top is part of an building envelope. It's the covering on the uppermost part of a building or shelter which provides protection from pets and weather, notably rain or snow, but also heat, wind and sunlight. The word denotes the framing or structure which facilitates that covering also.[1]The characteristics of a roof are reliant upon the goal of the building it includes, the available roof covering materials and the neighborhood traditions of engineering and wider principles of architectural design and practice and may also be governed by local or national 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 any garden conservatory protects plants from cold, wind, and rain, but admits light.

In lots of parts of the earth ceramic tiles have been the predominant roof material for years and years, if not millennia. Other roofer materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, polyurethane foam, PVC, slate, Teflon fabric, TPO, and hardwood shingles and shakes.
The construction of the roof depends upon its approach to support and the way the underneath space is bridged and set up roof top is pitched. The pitch is the viewpoint at which the roof goes up from its most affordable to highest point. Most US domestic architecture, except in very dry parts, has roofs that are sloped, or pitched. Although modern engineering elements such as drainpipes might remove the dependence on pitch, roofs are pitched for reasons of traditions and aesthetics. So the pitch is partly dependent upon stylistic factors, and partially to do with practicalities.
Some types of roofing, for example thatch, need 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 comparatively low angle. In locations where there is little rainfall, an almost even roof with a slight run-off provides enough protection against an occasional downpour. Drainpipes remove the need for a sloping roofing also.
A person that specializes in roof top construction is called a roofer.The durability of your roof covering is a matter of matter because the rooftop is usually the least accessible part of your building for purposes of repair and renewal, while its destruction or destruction can have serious effects.
Because the purpose of a roof is to safeguard people and their belongings from climatic elements, the insulating properties of any roofing are a factor in its framework and the decision of roofing materials.Some roofer materials, those of natural fibrous material specifically, such as thatch, have excellent insulating properties. For all those that not, extra insulation is installed under the outer layer 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 high temperature and cold, noise, dirt 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 heating system caused by the sun.Types of insulation are sensed or cheap sheeting, with a reflective surface sometimes, installed straight 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 increasingly 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 like the formation of glaciers dams about the overhanging eaves in winter, causing normal water from melted snow on top parts of the rooftop to permeate the roofing materials. Ice dams arise when warmth escapes through the uppermost area of the roof, and the snow at those true items melts, refreezing as it drips over the shingles, and collecting in the form of ice at the low points. This can lead to structural destruction from stress, like the damage of drainage and gutter systems.
