Standard Hip Roof Pitch

Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled.

Standard hip roof pitch.

A common range is given from 1 12 to 4 12 whereas conventional dimensions vary from 4 12 to 9 12 but the steep roofing technique follows slope above 9 12 with additional fasteners. The ibhs recommends a 4 to 6 pitch roof. As aforementioned there is no standard pitch of a roof. Each of the four sides of the roof slope downward there are no upright or vertical parts no gables etc on a hip roof.

The most daunting task is selecting the height. 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 height and rake of a roof are one of the important factors. One engineer recommends a 12 12 pitch for the new roof while another recommends a 7 12 pitch.

The most commonly used roof pitches fall in a range between 4 12 and 9 12. The typical roof slope follows specific materials and design techniques to ensure perfect safety from leakage. But the most commonly used pitches range between 4 12 and 9 12. Modern residential hip roof construction uses common pitch ratios in general.

Most roof s have a pitch in the 4 12 to 9 12 range. You write the pitch assuming a run of 12 inches thus the ratio would describe how much a roof rises for each foot of the run. Pitches above 9 12 are very highly angled and are designated steep slope roofs. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs.

Selecting the roof pitch. A hip roof design refers to a roof where the roof sides slope downwards from a middle peak with the rafter ends meeting the exterior walls of the house. The tall steep roofs are high priced and construct of those are complicated. The table below shows common roof pitches and the equivalent grade degrees and radians for each.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. How do you calculate the slope of a roof. There are always some limitations in the selection of the height. The most common hip roof pitch ratios fall between 4 12 and 6 12 although variations occur based on factors such as snow rain and wind conditions which is because steeper hip roof pitch ratios allow for less accumulations of snow and rain on the roof and lower ratios provide less wind resistance.
