Positive Pitched Roof

Watch out for complex roof lines.

Positive pitched roof.

It s easier for water to drain on a pitched roof compared to a structure that s more flat. Roofs steeper than 5 and 12 are difficult to walk on. This type of roof is more commonly seen in residential homes as the space directly underneath it is an attic their pitch or slope can be steep or gradual depending on the home s design and layout. This pitch sheds water well but is not too steep you can still have good roof overhangs to protect the building and the roof is just shallow enough in pitch that you can walk on the roof to service it.

A roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. Sometimes pitch is also expressed in. The term pitch and slope are often used interchangeably which is incorrect. My personal favorite pitch for a roof is a 5 and 12.

Flat roofs have no slope and are available in built up single ply. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12. Pitched roofs come in a variety of styles such as gable cross gable and hipped all of which are sloped to different degrees. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.

A 12 to 24 pitch is expressed as 1 2.
