The water drains into a gutter that is fed into a downpipe. A flat roof should have a watertight surface with a minimum finished fall of 1 in 80. They can drain internally or to an eaves gutter, which has a minimum 1 in 360 fall towards the downpipe. [7] The pitch of a pitched roof is determined by the construction material of the covering. For ...
Plumbing. A complex arrangement of rigid steel piping and stop valves regulate flow to various parts of the building, with an evident preference for right-angle pipe bends and orthogonal pipe routes. Plumbing is any system that conveys fluids for a wide range of applications.
Cricket (roofing) A cricket or saddle is a ridge structure designed to divert water on a roof around the high side of a large penetration, typically a skylight, equipment curb, or chimney. [1] In some cases, a cricket can be used to transition from one roof area to another. On low-slope and flat roofs with parapet walls, crickets are commonly ...
Purpose. The purpose of a leader head is to help transfer excess water from the roof onto downspouts, thus preventing the gutters from overflowing and water washing over the walls, which is a common occurrence in areas susceptible to heavy rain cycles. The use of leader heads also offers other benefits to the drainage system.
A downspout, waterspout, [1] downpipe, drain spout, drainpipe, [2] roof drain pipe, [3] or leader is a pipe for carrying rainwater from a rain gutter. The purpose of a downspout is to allow water from a gutter to reach the ground without dripping or splashing down the building structure. Downspouts are usually vertical and usually extend down ...
External floating roof tank. An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate. It consists of an open- topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. The roof rises and falls with the liquid level ...
Trees will soon destroy a sod roof. Photo: Roede. A sod roof, or turf roof, is a traditional Scandinavian type of green roof covered with sod on top of several layers of birch bark on gently sloping wooden roof boards. Until the late 19th century, it was the most common roof on rural log houses in Norway and large parts of the rest of Scandinavia.
Roof pitch. Roof pitch is the steepness of a roof expressed as a ratio of inch (es) rise per horizontal foot (or their metric equivalent), or as the angle in degrees its surface deviates from the horizontal. A flat roof has a pitch of zero in either instance; all other roofs are pitched. A roof that rises 3 inches per foot, for example, would ...
