Also known as pitched or peaked roof, gable roofs are some of the most popular roofs in the US. They are easily recognized by their triangular shape.
Pros: Gable roofs will easily shed water and snow, provide more space for the attic or vaulted ceilings and allow more ventilation. Their inherently simple design makes it easy to build them and cheaper than more complex designs.
Cons: Gable roofs can be problematic in high wind and hurricane areas. If the frames are not properly constructed with adequate supports, the roof can collapse.
High winds can also cause materials to peel away from gable roofs. If there is too much of an overhang, winds can create an uplift underneath and cause the roof to detach from the walls.
If a gable roof is used in high wind areas, be sure proper braces are used and have the roof inspected after a large storm to ensure no damage has occurred.
Note: It is recommended to use at least a 10/12 pitch or 40° angle, for snowy regions.
Types of Gable Roofs
Side Gable: A side gable is a basic pitched roof. It has two equal panels pitched at an angle, meet at a ridge in the middle of a building. The triangle section can be left open for an open gable roof, or it can be enclosed for a boxed gable roof.
Crossed Gable: A crossed gable roof is two gable roof sections put together at a right angle. The two ridges are perpendicular to each other. Lengths, pitches or heights may or may not differ from each other.
