High Slope Roof
The slope of a roof has an effect on the interior volume of a building the drainage the style and the material used.
High slope roof. 9 12 20 12 steep slope. The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. Roofs on victorian era houses were often sharply angled with a steep pitch. The steep roof of the tropical papua new guinea longhouse for example sweeps.
Roof slope is a very important aspect and it is considered the primary factor in roof design. High pitched roofs often need extra fasteners and their pitch can be as high as 21 12. The exact roof slope in degrees is given by the arctangent. Thus pitch is typically greater in areas of high rain or snowfall.
Visually this roof appears flat. Here are the equations you may use to solve for the length of the slope and the rafter. Think of a classic addams family haunted house with its soaring peaks and you have a. 2 12 4 12 conventional slope roof.
Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow. This pitch might be as low as 1 12. You can also calculate roof pitch even without using a roof slope calculator. Use the following formula which also describes a right triangle.
