The form of a gable roof is determined at the design stage. It also depends on the further operation of the attic. There are three main types of gable roof:
Symmetrical. This is the most common variant which provides reliable device and uniform distribution of the loads. It offers safe work but there is one basic problem – the inability to be build an attic later. There are very sharp corners that form portions attic which is useless.

Simple asymmetrical. There is forming an angle greater than 45 degrees, which provides very useful space. This way you are allowed to organize, additional living rooms under the gable roof.
Bent. The fracture of the gable roof can be internal or external. Thanks to custom design it is possible to use the attic space for everything. Calculations for installing the trusses here are much more complicated.
