2 12 Roof Pitch Angle

Most roof s have a pitch in the 4 12 to 9 12 range.

2 12 roof pitch angle.

In the roofing trade the go to term is pitch and it is expressed in terms of 12 inches so the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally. 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. Roof pitch defined and explained. While measuring tap to hear the spoken angle continuously as it changes.

2 12 roof pitch angle 9 46 degrees. The combination of two numbers are used to display or show the roof pitch. On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length. Resilient asphalt shingles lie much flatter to the substrate than slate tile and concrete which keeps water from being easily blown under them.

Visit this page on your phone to directly measure pitch and angles. Enter any angle or fraction of angle to find pitch. Conventional forms range from 4 12 9 12 and steep slope roofing is more than 9 12 and requires extra fasteners. A pitch of 2 12 is the minimum pitch for shingles made of asphalt so your roof just barely makes the cut off for one of the most popular roofing material options.

Roof angles and rafter plumb cuts. If a roof rises 2 in a length of 12 this is 2 12 roof pitch. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. Enter any pitch or fraction of pitch to find angle.
