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.

2 12 roof slope. A 2 12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance. I am going to be roofing a building that has some areas that are 2 in 12 pitch. Also if asphalt shingles are installed on a roof slope of 2 12 to 4 12. Many studies on roofed structures have been performed in the past.

The present study demonstrates the pressure variations due to wind load on the pyramidal roof of a square plan low rise building with 15 wall openings through cfd computational fluid dynamics simulation. Roof slopes in degrees percentage and rise in run rise over run. Low pitched roofs are generally difficult to maintain and you need special materials to prevent leaks. I am going to be using comp shingles and double felt.

Minimum slope requirements depending on the roof profile there are minimum roof slope requirements for each panel which need to be considered. This page also explains how to convert one to another. If the slope is 4 12 the pitch for the. Asphalt shingles can only be installed on roof slopes of 2 12 or greater.

The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. Roof shape and slope are both important parameters for the safety of a structure especially when facing wind loads. The table shows the equivalent ways of expressing the same roof pitch slope. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

These roofs have a pitch less than 4 12. Simply put it s a shallow roof. Please share any tricks or tips for making this roof water tight. The minimum slope for standing seam of roof systems shall be one quarter unit vertical in 12 units horizontal 2 percent slope.
