![]() Sedum roofs are cool in the summer and warm in the winter and are a green option as they attract insects that help pollination. Modern sedum roofs have a waterproof layer beneath the soil, as rainwater will pass through it, but they absorb a lot of rain, which keeps the plants thriving. They’re living roofs, with a soil substrate on which small plants grow, and have been used for millennia around the world. Sedum roofs are both very old and very new. Pyramid hipĪ pyramid hip roof is where the building is square, and instead of a ridge, all four triangular roofs meet at a single apex point in the middle. The difference is that there are no gable ends – the walls end at gutter level and the roofs slope upwards towards the ridge. Like a crossed gable, a crossed hip is the shape that is created when the building is an X, T or L-shape. Whichever direction you look at a hip roof from, you will always see sloping roofs, unlike a gable roof, which will look rectangular if viewed from 90 degrees to the gutter. ![]() If the house is rectangular, that means two of the faces will be triangular, and the other two will be trapeziums. The roof slopes upwards from all four walls, often at quite a gentle angle, and the four faces meet at the ridge at the top. The hip roof is the second most common form after gable roofs. They’re ideal for lean-tos and carports as they are light and require little construction underneath them. They are an inexpensive form of roofing, usually made of PVC or a galvanised metal, and they require little sealing as the panels can simply be overlapped at the last few waves to maintain water tightness. They can be rounded or square-edged, but are always arranged so the corrugations are aligned vertically so water can run off them. Corrugated roofĬorrugations are repeated wave-like patterns across an area of roofing. If there is an upstairs, extra space can be won by the use of dormer windows, otherwise the effective floor space would be too small. The A-frame roof is similar to the gable roof, but the roof reaches all the way to the ground (or a short distance above ground level) – like an “A” shape. A glass roof is preferable for maximum light, but the amount of light entering through the side panes is usually sufficient for most conservatories, so there’s often a traditional roof, perhaps with skylights. Because there’s no set shape to a conservatory, they can take many forms, for example hip, flat or gable. Conservatory roofĬonservatory roofs fall into three categories: glazed, opaque and combination. However, with skylights or dormer windows, the top floor can still be light, airy and spacious. ![]() They are often used to create an extra floor, although it will only be half the size of the floor(s) below because the roof will be lower on one side. Saltbox roofĪ saltbox roof is similar to a gable, but the two roof faces are different sizes, with one wall higher than the opposite, plus two gable ends with irregular shapes. Viewed from above, the house will have an X, T or L shape. Crossed gableĪ crossed gable roof is where two or more separate gable roofs project at 90 degrees from the main body of the house. It will usually project outwards at the gable ends by a small amount, and the ends will probably be boarded or tiled rather than brick. With box gable roofs, the main structure of the house consists of four rectangular walls, and the roof sits on top as a separate architectural part. With open gables, the walls at the gable ends visibly reach the peak of the roof in a triangular form. ![]() Gable roofs also have larger loft spaces than hip roofs (see below), which is another added benefit. Because the triangle is the most stable shape in engineering, the gable forms a strong roof, making it one of the most popular choices for British homes. Think Monopoly houses and you’ll get the idea. This means the vertical walls on two opposite sides reach all the way to the apex of the roof, but on the other two sides they only reach the gutter. It consists of two equally sized sloping roof faces that meet at the top ridge in the middle on a rectangular house. The gable roof is the most basic type of sloping roof. Well that’s about to change – we’ll make a roof-spotter of you yet! Gable Roof The strange thing is, even though they’re fundamental structural elements, with functional as well as aesthetic purposes, most of us probably don’t pay too much attention to them, even when we’re home-seeking. Do you know your box gable from your open gable? Your bonnet from your gambrel? If you have no idea what we’re talking about, these are just some of the different types of roofs that sit atop the nation’s homes.
