A roof top is part of any building envelope. It's the covering on the uppermost part of a building or shelter which gives protection from pets and weather, notably rain or snow, but heat also, wind and sunlight. The term denotes the framing or framework which supports that covering also.[1]The characteristics of the roof are reliant upon the goal of the building so it covers, the available roofer materials and the neighborhood traditions of construction and wider ideas of architectural design and practice and could also be governed by local or national legislation. In most countries a roof protects against rain primarily. A verandah might be roofed with material that shields 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 globe ceramic tiles have been the predominant roofing materials 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 timber shingles and shakes.
The construction of your roof depends upon its method of support and how the underneath space is bridged and whether or not the roof top is pitched. The pitch is the angle of which the roof rises from its lowest to highest point. Most US home architecture, except in very dry areas, has roofs that are sloped, or pitched. Although modern engineering elements such as drainpipes may remove the dependence on pitch, roofs are pitched for reasons of looks and custom. So the pitch is partly dependent upon stylistic factors, and partially regarding practicalities.
Some types of roof covering, for example thatch, require 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 relatively low angle. In locations where there is little rainfall, an almost chiseled roof with hook run-off provides adequate protection against an occasional downpour. Drainpipes take away the need for a sloping roof covering also.
Somebody who specializes in roof structure construction is called a roofer.The durability of any roof top is a matter of matter because the roofing is often the least accessible part of an building for purposes of repair and renewal, while its devastation or damage can have serious effects.
Because the purpose of a roof covering is to protect people and their property from climatic elements, the insulating properties of any roof structure are a concern in its structure and the decision of roofing materials.Some roofer materials, specifically those of natural fibrous material, 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 goal of a roof is to insulate against heating and cold, noise, dirt and grime and frequently from the droppings and lice of wild birds who frequently choose roofs as nesting places.
Concrete tiles can be utilized as insulation. When installed departing a space between the tiles and the roof surface, it can reduce heat caused by sunlight.Types of insulation are clear plastic or noticed sheeting, with a reflective surface sometimes, installed immediately below the tiles or other materials; 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 more and more, and in some instances are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal emittance.
Poorly insulated and ventilated roofing can have problems with problems like the formation of ice dams across the overhanging eaves in winter, causing water from melted snow on higher elements of the roof top to permeate the roofing material. Ice dams appear when high temperature escapes through the uppermost part of the roof, and the snow at those things melts, refreezing as it drips over the shingles, and collecting in the form of ice at the lower points. This may result in structural destruction from stress, like the damage of drainage and gutter systems.
