Make Roof Pitch Steep

A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof.

Make roof pitch steep.

A roof with a pitch of less than 5 has a shallow slope and a roof pitch of more than 8 appears to have a steep slope. Roof pitch is the measurement of roof steepness. Single ply or torch down roof structures are made specifically for flatter rooftops and cannot be used when building a steeper roof. Which is equal to 1 4 or 1 3 the total span of the building not counting any overhang.

Pitch for a gable roof the most common is generally 1 4 or 1 3. The way pitch also known as roof slope is measured is rise over run. Most roof s have a pitch in the 4 12 to 9 12 range. Pitch is a measure of the steepness of a roof.

The table below shows common roof pitches and the equivalent grade degrees and radians for each. Pitch can vary a great deal from a shallow slope up to a very steep pitch. The pitch of the roof is determined by the vertical rise in inches for every horizontal twelve inch length. So if your roof rises 4 inches for every 12 inches of horizontal length then the pitch of your roof is expressed as 4 12.

A flat roof would have a 2 12 pitch while the average roof pitch would be between 4 12 and 9 12. A roof that slopes upward vertically 6 inches for every 12 inches measured horizontally is said to have a 6 pitch a vertical rise of 8 inches per foot is an 8 pitch and so on. Meanwhile tile and shingles do better on steep pitches while low pitches may need metal or concrete roofing instead limiting your design options.
