15 Degree Slope Roof

Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials.

15 degree slope roof. An example for a steep sloped roof is 8 12. Most roof s have a pitch in the 4 12 to 9 12 range. What degree angle is a 12 12 pitch roof. Down to 17 5 degree pitches smooth with a headlap of 100mm.

Down to 22 5 degree pitches smooth with a headlap of 75mm. With the use of this converter it will be easier for you to locate a 30 degree roof pitch 20 degree roof pitch 25 degree roof pitch or a 15 degree roof pitch. It is uncommon to find a roof below 15 but for those very low pitch applications there are interlocking clay pantiles available suitable for use down to 12 5. A 6 rise in a 12 inch run.

Divide the first part of the ratio by 12 to work out the pitch. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Convert a roof pitch of rise in 12 to a roof angle in degrees.

Traditionally a minimum roof pitch of 20 was recommended in bs 5534 but modern tiles and slates have now been designed for applications as low as 15. However if you to do the process using your own knowledge you can still convert pitch to degrees by dividing the rise and run and get its corresponding measurement. To put it in perspective the angle of this slope would be around 30 degrees. But that would be a wrong assumption.

Common roof pitches and equivalent grade degree and radian angles. We also provide a number of other low pitch concrete interlocking solutions such as the mendip and wessex tiles each able to perform at pitches of 15 degrees and our new mendip 12 5 can be used at an even lower pitch of 12 5. Find the inverse tangent of the pitch to find the angle in degrees. 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.

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. This means that the rise of the slope goes up or down 8 inches for every 12 inches. Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. With a 12 in 12 slope the wall or roof rises 12 inches in a 12 inch run a 12 in 12 slope 45 one could be inclined to assume that a 6 in 12 slope would equal half of that 22 5.

To convert between american roofing ratios and pitch degrees follow these steps.
