A roof top is part of the building envelope. It's the covering on the uppermost part of the building or shelter which provides protection from animals and weather, notably rain or snow, but heat also, sunlight and wind. The word denotes the framing or composition which helps that covering also.[1]The characteristics of your roof are reliant upon the goal of the building it addresses, the available roofing materials and the neighborhood traditions of development and wider principles of architectural design and practice and could also be governed by local or nationwide legislation. In most countries a roof protects mostly against rain. A verandah might be roofed with materials that defends against sunlight but admits the other elements. The roof of any garden conservatory protects plants from cold, wind, and rain, but admits light.

In many elements of the global world ceramic tiles have been the predominant roofer material for years and years, if not millennia. Other roofer materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon cloth, TPO, and hardwood shingles and shakes.
The construction of the roof is determined by its approach to support and how the underneath space is bridged and set up roof is pitched. The pitch is the perspective of which the roof rises from its most affordable to highest point. Most US local architecture, except in very dry parts, has roofs that are sloped, or pitched. Although modern development elements such as drainpipes may take away the dependence on pitch, roofs are pitched for reasons of appearance and traditions. So the pitch is dependent after stylistic factors partly, and partially to do with practicalities.
Some types of roofer, for example thatch, require 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 rainwater, an almost chiseled roof with hook run-off provides sufficient protection against an occasional downpour. Drainpipes also remove the need for a sloping roof structure.
Somebody who specializes in roof covering construction is named a roofer.The durability of any roof top is a subject of concern 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 protect people and their possessions from climatic elements, the insulating properties of an roof covering are a awareness in its composition and the decision of roofing materials.Some roofing materials, specifically those of natural fibrous material, such as thatch, have excellent insulating properties. For all those that do not, extra insulation is often installed under the exterior covering. 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 heat and cold, noises, mud and frequently from the lice and droppings of birds who frequently choose roofs as nesting places.
Cement tiles can be utilized as insulation. When installed going out of a space between the tiles and the roof surface, it can reduce heating up caused by the sun.Forms of insulation are thought or plastic sheeting, sometimes with a reflective surface, installed below the tiles or other material 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 popular significantly, and in some full cases are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly insulated and ventilated roofing can suffer from problems like the formation of snow dams surrounding the overhanging eaves in cold weather, causing normal water from melted snow on higher parts of the roof covering to penetrate the roofing material. Ice dams appear when heat escapes through the uppermost area of the roof, and the snow at those true points melts, refreezing as it drips over the shingles, and collecting in the form of ice at the low points. This can result in structural destruction from stress, including the damage of gutter and drainage systems.
