Sloped roof 2 per 12.

Metal roof slope is expressed by a ratio indicating the roof pitch which notes the vertical rise of the roof in inches for every 12 inches the roof runs horizontally in other words dividing the vertical rise and its horizontal span. Once you ve figured out the pitch of your roof you can consult the following chart to discover the slope factor and hip valley factor. That is the roof s rise. This means for every 12 horizontal units the roof must rise a minimum of 2 vertical units.

3 12 1 2 12 and 1 4 12. If a roof rises 2 in a length of 12 this is 2 12 roof pitch. Conventional roofs are the easiest to construct and you can walk on them safely. A 2 12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance.

These roofs have a pitch less than 4 12. For example if you measure 4 inches the pitch of your roof is 4 12. Roof slope style. There are two main categories of roofing.

The table below shows common roof pitches and the equivalent grade degrees and radians for each. Simply put it s a shallow roof. 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. The most common slopes are.

They have a pitch ranging from 4 12 to 9 12. Most roof s have a pitch in the 4 12 to 9 12 range. 2 12 roof pitch angle 9 46 degrees. Conventional slope roof range between 4 in 12 and 8 in 12.

High pitched roofs often need extra fasteners and their pitch can be as high as 21 12. A flat roof has a slope of 2 in 12 or less. A low slope roof is anywhere from 2 in 12 to 4 in 12. Also if asphalt shingles are installed on a roof slope of 2 12 to 4 12 it shall be provided with a double underlayment application.

Download the slope chart pdf. That means the roof doesn t shed water as easily as steeper roofs which is why choosing the right type of roofing material is so important. You can also calculate roof pitch even without using a roof slope calculator.
