The Advantages of Gable Roof
Roof shapes vary a lot from region to region, but gable roof is the simplest and most seen roof shape, especially in areas with colder weather. That is a roof all people think of when they imagine a house. It consists of two sections, placed in opposite directions and forming an inverted V. Simple to design and build, gable roof is most commonly used in many geographic regions.
Gable roof is inexpensive, much more affordable than any roofing shape. It allows many design variations but is based on simplest design principles. Gable roof shed water and snow easily because of its triangular shape.
Types of Gable Roofs
Side Gable: Basic shape, has two gable roof panels pitched at a certain angle. Panels are equal. It can be open – with an open triangle section, or enclosed – a boxed roof.
Crossed Gable: Two roof sections positioned at a right angle. Used for houses with separate wings. Often built on Tudor-styled houses.
Front Gable: Place at the house entrance. Often built on Colonial-styled houses.
Dutch Gable: A combination of hip roof and gable roof. Also known as gambrel.
There are other categorizations, but this is the simplest one.
Gable Roof Disadvantages
When a wind is extremely strong, gable roof can collapse if not built properly. The roof can be destroyed in a hurricane, for example, so gable roofs in areas with very strong winds require special support in construction. Also, roofing material can peel away due to high winds. Gable roof can be covered with many materials. Mostly, those materials include metal, concrete tiles, terra cotta tiles, asphalt shingles. If the roof has a dormer, it needs to have a standing seam to prevent roof leaks. In regions with a lot of snow, it is recommended to use at least 40° angle.
