A roof is part of a building that is one of the most complex parts and it is essential for a good strcuture. It is the covering on the uppermost part of a building and gives the protection from weather or animals. The word roof means the framing or structure which supports that covering. The interior roof construction is a frame and roof covering that is located in most suburban houses in cold and quiet climatic conditions. Such roofs are made of main wood, have different shapes and are covered with different materials.
Types of roofs
There are larger types of roofing depending on how much snowfall per year. Modern wooden roofs are framed with joint steam scissors, or prefabricated woodcutters conveyed together from the cone plate. Wooden frames and a historical building can be framed by main slopes or wooden carriers. Two types of roofs are designed, hot or cold roofs in the case of how they are designed and built for thermal ventilation and insulation. The inclination or roof tilting of the roof deck is primarily based on the material of the roof cover and the aesthetic design. Flat roofs are inclined to about 10 degrees to pour water. Flot roots in houses are the prime priority and arid regions.
Roofs in extreme weather conditions
In large areas of the wind, such as Pacific ocean, the main engineering attention is to keep the roof down during heavy storms. Each component of the roof, as well as the rest of the structure, must withstand the power of raising the high wind speed. This is achieved by using metal cords attached to each rafter or carrier. This is not a problem in areas that are not prone to strong winds or extreme weather disturbances.
Standards in some countries
In the United Kingdom, a concrete tiled roof will normally have rafters at 60 cm centers, roof battens at 30 cm centers and ceiling joists at 40 cm centers. In the States, they still use units of measurement and framing members are typically spaced 16 or 24 inches apart. The roof frame can be opened with a chimney or a roof window. Chimneys are usually built with drainage water known as cricket or saddle above the chimney while the flashes have their use when you need to close the space between the chimney and the roof material.
