Roofing is the process of covering the top most part of a house. A covered building will look good, give cover from climate effects and make the inside of the building cool. Building covering comes in various forms. Roofs are constructed considering the intended purpose of the building, kinds of covers available, preferred choices and many more reasons.
Types of tangible roofing items, the actual building of the roof and the lasting time of the roof are factors to be considered before doing a building cover. The kinds of roofing materials commonly used are grass, iron sheets and concrete. These are also different when it comes to the cost, effectiveness and durability.
A major division of roofs are flat roofs and pitched roofs. A roof that moves from a lower to a higher point is said to be pitched. A flat roof on the other hand is a roof that has no visible change of angle from one end to the other. Since it is not easy to access a roof in future for matters of repair or replacement, durability of the roof should be highly considered.
A structure that holds and an outward cover are the parts of a roof. Robust and durable wood and metal are used to construct the supporting part of the roof. Longevity in the material used for creating the final part of a roof should be put into consideration. Two factors are considered for constructing a roof.
A roof gives the cover that a building requires. A roof that is able to give protection against climate effects to individuals and their property is termed as an insulating roof. Some roofing materials especially the natural fibrous kinds like thatched grass, have excellent insulation properties. Extra insulating material is usually incorporated onto the inner side of a roof to give better insulation. For a roof with inadequate insulation, a ceiling could be built to provide better protection.
Similarly, roofs are constructed to keep out water. A roof should be constructed in such a way that it repels much water to the right place and in a suitable manner to avoid damage. A horizontal roof should have a considerable amount of slope which enables water to be directed away. In most cases a gutter, which is usually a duct or a designated trough that directs rain water from a structure is used. This water can either be directed to a safe place away from the building or even stored in tanks.
Given the current technologies, we have roofs that have solar panels on top of them to provide for electric power to the building. Some solar systems on a roof structure are able to generate heated air and heated water. Solar panels are either added to an existing roof structure built from different materials or built in as the roof.
