Common Roof Pitch Designs
The Double-Pitched roof is the most common design for roofs that have a pitch. This design can be symmetrical or asymmetrical. The first type usually contains two surfaces that meet at the ridge ad form a perfect triangle. An asymmetrical double pitch is where the ridge does not meet at the centre point. This means that the surfaces are not equal in length.
The triangles at each end of the house are Gable ends which are traditional for Gable roof type designs.
A mono-pitched roof usually has a pitch which is lower than the height of the ceiling. This type of design can also serve as an extra to the existing roof. The ideal pitch was more than 20 degrees but has fallen to 15 degrees if using slate of tiles.
A Couple Roof is a pitched roof in it’s most basic design form. The rafters slope upwards to meet at the centre ridge. This roof type is no longer in use much due to design drawbacks. There is no lateral support which makes this design a bad option for extreme weather.
A Collar Roof does not have the design drawback of the couple roof but does have another limitation. This design has a max span of 4.5 metres (14.7 feet). Although a collar roof is more common than a couple roof, it’s still not a popular option.
