Slope roof section.

A roof similar to a mansard but sloped in one direction rather than both. Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run. When required for steep slope roofs section 1507 in the ibc and section r905 1 2 of the irc specify the use of an ice barrier that consists of either two layers of underlayment cemented together or a self adhering polymer modified bitumen sheet at eaves and valleys. A roof slope of 7 12 is also good and can provide the additional benefit of helping minimize the effects of wind driven rain.

The steep slope may be curved. Roof coverings installed on lowslope roofs roof slope 2 12 in accordance with section 1507 shall resist impact damage based on the results of tests conducted in accordance with astm d3746 astm d4272 cgsb 37 gp 52m or the resistance to foot traffic test in section 5 5 of fm 4470. An element of the second empire architectural style mansard style in the u s. However from the wind uplift mitigation perspective a 7 12 roof slope can be considered as a two story building due to the higher overall steepness and profile of the roof.

This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.
