A roof top is part of the building envelope. It is the covering on the uppermost part of your building or shelter which provides protection from family 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 the roof are based mostly upon the goal of the building that this addresses, the available roof materials and the local traditions of structure and wider concepts of architectural design and practice and may also be governed by local or national legislation. In most countries a roof protects generally against rain. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of your garden conservatory protects plants from cold, wind, and rain, but admits light.

In many parts of the global world ceramic tiles have been the predominant roofer material for centuries, if not millennia. Other roof covering materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, polyurethane foam, PVC, slate, Teflon textile, TPO, and hardwood shingles and shakes.
The construction of your roof is determined by its approach to support and the way the underneath space is bridged and set up roof top is pitched. The pitch is the viewpoint of which the roof rises from its most affordable to highest point. Most US local architecture, except in very dried areas, has roofs that are sloped, or pitched. Although modern structure elements such as drainpipes may take away the dependence on pitch, roofs are pitched for reasons of custom and looks. So the pitch is partly dependent after stylistic factors, and partially to do with practicalities.
Some types of roof covering, for example thatch, need a steep pitch in order to be durable and waterproof. Other styles of roofing, for example pantiles, are unstable on the steeply pitched roof but provide excellent weather protection at a relatively low angle. In parts where there is little rainwater, an almost flat roof with a slight run-off provides sufficient protection against an intermittent downpour. Drainpipes also take away the need for a sloping roof top.
A person that specializes in rooftop construction is named a roofer.The durability of any rooftop is a subject of concern because the roofing is often the least accessible part of a building for purposes of repair and renewal, while its damage or devastation can have serious results.
Because the purpose of a roofing is to protect people and their belongings from climatic elements, the insulating properties of an rooftop are a consideration in its framework and the decision of roofing materials.Some roofer materials, particularly those of natural fibrous materials, such as thatch, have excellent insulating properties. For all those that not, extra insulation is installed under the outside level often. In developed countries, the majority of dwellings have a ceiling installed under the structural members of the roof. The goal of a roof is to insulate against heating and cold, noises, dirt and grime and frequently from the droppings and lice of wild birds who frequently choose roofs as nesting places.
Concrete tiles can be used as insulation. When installed leaving a space between your tiles and the roof covering surface, it can reduce heating up caused by the sun.Types of insulation are thought or cheap sheeting, sometimes with a reflective surface, 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 popular more and more, 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 covering can have problems with problems like the formation of ice dams across the overhanging eaves in winter, causing drinking water from melted snow on top elements of the roof covering to permeate the roofing materials. Ice dams occur when warmth escapes through the uppermost area of the roof, and the snow at those points melts, refreezing as it drips along the shingles, and collecting in the form of ice at the low points. This can result in structural harm from stress, like the destruction of gutter and drainage systems.
