Although determining the slope of a roof

There are several types of roofs (flat , round or sloping ) and each is a roof slope. However, determining the appropriate slope to a roof is not obvious , it is advisable to refer to specialized structures. These offer the results of their calculations through research guides . There are double slope roofs , constructed in this manner , these roofs have a structure unlike the other ( single slope).

In areas with high rainfall or snow often , the roofs are steep . This is to facilitate the descent of the snow or the flow of rainwater while in regions where drought prevails , the roofs are often flat . Inclined in the hexagon with various forms of slope roofs are encountered. In fact if you need to build a roof , it is imperative to learn the town hall to find the angle that you must follow , this is especially important for insurance that might not cover an incident , such as a collapse of the roof fall to an outstanding snow, if the roof pitch is not within the allowable standard.

How to calculate the slope of a roof?

The means and methods of construction of housing is very different , it is therefore difficult to define in a general value of the slope of a roof . The calculation of the slope is taking into account factors such as the width of the roof , the height of the pinion, the total number of sides , but especially of the materials used . A slope of 20 % means that for every 100 meters (horizontally ) , it rises 20 meters (vertical ) . The slope is the relationship that develops between the distance of the vertical and the horizontal. This is the calculation of the tangent of the angle alpha and the slope obtained by a division of the pinion height by the width of the ground ( the plot on which it is located) .

Various roofs and their slopes

There are roofs, slate roof terrace , etc … corresponds each to a roof slope. For a collection with natural slate , a slope of 15 ° to the vertical than enough , as the fiber cement slates , the slope can be between 20 ° and 30 °. However , it is important to know that for a large slope , there is a small format slate large format . To place the slate must use either stainless hooks to prevent rust or nails on the floor or on aerobatics. Canada, France and Spain are the main producers of natural slate country. A flat roof can have a slope that varies from 2 to 5% depending on the size of habitat cover . Sealing the vapor space , blankets , slope roof , support , insulation and protection are the elements of a terrace. Thus, the slope of the roof terrace is accessible by 2% inaccessible have a slope close to 1 %. A layer of concrete can allow flat roofs have a slight slope. Small holes (hole) protected by pieces of pipes are placed at the bottom of the slope to facilitate the evacuation of rainwater down into the gutters discharge all wastewater from the house.

The green roof  is very suitable for the natural treatment of pollution , thermal insulation and especially the flow of rainwater . A green roof is covered with grass , straw or shrubs. This type of roof existed since ancient times and its use has increased in the twentieth century in the northern European continent particularly in countries such as Switzerland , Germany, the Netherlands etc … who use them as templates in the construction of large buildings. Slope for this type of roof is approximately 40 ° . In France , the gabled roof is preferred because it puts more value in constructions with a beautiful plane. The roof is composed of a large number of elements, but it is important to pay close attention to the structure of which depends on the efficiency, sustainability and roof strength . A double slope of 50 ° corresponds perfectly to this roof.
