Getting to Know more about Gable Roof

A gable roofis a variant of roofing that is much more common in those areas with climates of cold to temperate types. Design-wise, this type of roofing is formed by two sloping roof sections, arranged in such a way that the highest horizontal edges meet at the top. Construction-wise, this roof is supported by elements such as purlins, trusses, and rafters while the height of the gutters and the pitch of the roof vary from one another.

Gable Roof: Advantages, Disadvantages, and Types

This roofing type is common thanks to its versatility. In those areas that frequently see strong wind current, gable roofs are designed steeply in order to prevent water from entering the building. In those areas under the categories of alpine and mountainous, gable roofs are built shallower because this constructions means that the roofs can withstand snow better. Another thing that makes gable roofs preferable is their simplicity. Each roof section is rectangular in shape and the roof timbers are much easier to construct. This causes gable roofs to have the benefits other roofing types cannot offer. They (the gable roofs) employ fewer details so they require less work and cost. Asymmetrical gable roofs are created when the two roof sections are different in the length of their pitch.

A gable roofis advantageous because it is not as expensive as other roofing, quite flexible to be designed is several different ways, employs simple principles of design, and is resistant to weather. But its design also makes it only possible to use gable window or roof windows to illuminate the interior. Plus, buildings with low-pitch gable roofs see a reduced living space to accommodate the steep design of the roof sections. Gable roofs are categorized based on their angular pitch:

  1. Shallow gable: a pitch of ≤ 30°
  2. New German/angled roof: a pitch of 45°
  3. Gothic/Old German: a pitch of >62°
  4. Old Franconian/Old French: a pitch of 60°
