Gable roof plans options

Among the large variety of roof types, gable roof is considered to be one of the most popular. It has some important advantages, such as simple design, excellent stability and high versatility. Also it is need to say that there are a lot of different gable roof plans, each of which has its own features and advantages.

In general, gable roof consists of two inclined rectangular planes – roof slopes, which must be installed at a certain angle to the outer walls of the building. The angle of the roof slopes allows you to ensure the natural flow of precipitation (rain, melt water) from the roof.

During the planning of gable roof it is important to pay attention to the angle of roof slopes. This parameter depends on the climatic features of a specific region. Thus, roof with a steep angle should be installed in regions with high level of precipitation. Areas with strong winds require the installation of gentle slopes. This will allow to reduce the wind load.

The angle of roof slope should lay in the range of 5-90 degrees. Also one of the most common solutions is angle in the range of 35-45 degrees. This option is the most economical and convenient. But, on the other hand, you will get too cold room, so it will be uninhabitable.

If you need to arrange the dwelling room in your attic, you should choose sloping gable roof. In this case the upper part of the roof will be flatter and the lower will have steep slope. Therefore, attic space will be increased and you will have the opportunity to use it as loft.

Thus you can use following solutions for your gable roof:

  • Roof with uneven angles of slopes

Such type of gable roof has a really original look. But, on the other side, here you can feel the lack of the rational use of attic.
