A rooftop is part of a building envelope. It's the covering on the uppermost part of a building or shelter which provides protection from pets or animals and weather, notably rain or snow, but also heat, sunlight and wind. The word also denotes the framing or structure which supports that covering.[1]The characteristics of a roof are dependent upon the goal of the building that it protects, the available roof materials and the local traditions of building and wider concepts of architectural design and practice and could also be governed by local or countrywide legislation. In most countries a roof protects mainly against rain. A verandah might be roofed with material that defends against sunshine 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 roofing material for centuries, if not millennia. Other roofing materials include asphalt, coal tar pitch, EPDM silicone, Hypalon, reboundable foam, PVC, slate, Teflon textile, TPO, and lumber shingles and shakes.
The construction of any roof is determined by its approach to support and how the underneath space is bridged and set up roof top is pitched. The pitch is the perspective at which the roof increases from its most affordable to highest point. Most US local 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 aesthetics. So the pitch is partly dependent upon stylistic factors, and partially to do with practicalities.
Some types of roofer, for example thatch, need a steep pitch in order to be durable and waterproof. Other types of roofing, for example pantiles, are unstable on a steeply pitched roof but provide excellent weather protection at a relatively low angle. In areas where there is little rainwater, an almost smooth roof with hook run-off provides sufficient protection against an occasional downpour. Drainpipes also take away the need for a sloping roof covering.
Somebody who specializes in rooftop construction is named a roofer.The durability of your roof is a subject of matter because the roof structure is often the least accessible part of any building for purposes of repair and renewal, while its harm or damage can have serious effects.
Because the reason for a roof is to protect people and their property from climatic elements, the insulating properties of the rooftop are a consideration in its structure and the choice of roofing materials.Some roofing materials, particularly those of natural fibrous material, such as thatch, have excellent insulating properties. For those that not, extra insulation is installed under the exterior covering often. In developed countries, nearly all dwellings have a ceiling installed under the structural members of the roof. The goal of a ceiling is to insulate against high temperature and cold, sound, dirt and frequently from the lice and droppings of wild birds who frequently choose roofs as nesting places.
Concrete tiles can be utilized as insulation. When installed giving a space between the tiles and the roof covering surface, it can reduce heating system caused by the sun.Types of insulation are clear plastic or noticed sheeting, with a reflective surface sometimes, installed below the tiles or other materials straight; 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 ever more, and occasionally are mandated by local codes. Cool roofs are thought as roofs with both high reflectivity and high thermal emittance.
Poorly covered and ventilated roof can have problems with problems such as the formation of ice dams round the overhanging eaves in cold weather, causing water from melted snow on top parts of the roof structure to permeate the roofing materials. Ice dams happen when warmth escapes through the uppermost part of the roof, and the snow at those true points melts, refreezing as it drips along the shingles, and collecting by means of ice at the low points. This may result in structural damage from stress, including the damage of gutter and drainage systems.
