![]() This is made up of two sloping roof faces that are equal in size and meet at a ridge at the top. The most common type of gable roof is the open gable. They are also one of the simplest and instantly recognisable types of roof. Gable roofs are one of the most popular choices for UK houses, offering good roof space and being strong, stable and easy to construct. Valley: The internal angle between two sloping roofs.Dormer: A vertical window projecting out from the main roof, usually at a 90 degree angle.Eaves: The lower edge of the roof (this is usually where soffits, guttering and fascia will all be located).Ridge: The horizontal peak of the roof where roof faces meet.Hip: The external angle where two sides of a roof meet.Gable: The triangular-shaped section of the wall at the end of a ridged roof.In this example the, roof has 1 roof plane.Here, we have aimed to cover the most common types of roof you are likely to come across in order to help you ensure you know exactly what your options are and which style will best suit your needs.īefore getting to grips with the various types of roof out there, it helps to understand the jargon surrounding them. In most cases, flat roofs are just 1 or 2 degrees. The difference is that a flat roof is usually 5 degree pitch or less. Note that a flat roof looks the same in plan view as a skillion. This roof type is a single slope that can be any pitch. It is primarily a hip roof with a gable added on.ĭutch gable styled roofs add a bit more design feature to a standard hip roof. This roof type is a combination of a hip roof and a gable roof. Gable roofs are not a good choice for cyclonic areas due to the large gable end walls that are exposed to wind forces. In this example the, roof has 2 roof planes. This is one of the easiest roof types to draw and also build.Ī gable is basically a triangle shaped roof. In this roof type, there are 2 planes only with a ridge at the top. This is a good roof style for use in cyclonic areas as there are no high walls exposed to wind forces like there are in gable roofs.īuilding a hip roof has more structural members required to build it compared to a gable roof. ![]() In this example the, roof has 4 roof planes. The hips are usually drawn at 45degree angles, unless there are 2 different roof pitches involved, then the hips are not at 45 degrees. In this roof type, the roof is made up of what are called hips. The fall usually is shown in the direction going towards the gutter or box gutter. For more examples, look at the illustrations below, I have included the number of planes shown in the description.įall - When drawn on a plan, this shows the direction the roof plane falls towards. For instance, a simple singular gable roof is made of 2 planes as it has 2 sides of the roof. Roof Plane - This describes a single side of the roof. This roof is steeper as the pitch is greater (60 degrees) Roof Ptch - In this example, the pitch is 25degrees. The greater the pitch, the steeper the roof is as shown in the diagrams below. Sometimes referred to as the slope or angle, but the correct term is pitch. Roof Pitch - The roof pitch is the angle that the roof slopes at in degrees. Below is a description of the basic types of roofs used and what they look like when drawn in plan view and in isometric view. There are many different types of roof types used on buildings.
