Roof slope factor.

Calculating the roof slope factor is not that difficult. Roof pitch angle and slope factor charts. A 10 slope roof should not be confused with a 10 pitch roof as a 10 slope roof means that the roof rises by ten inches for every foot of run. 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.

Enter 6 into the calculator slope factor 1 1180 multiply the roof length by the gable wall length 40 24 960 multiply this amount by the slope factor 960 1 1180 1073 28 the area of this roof 1073 3 sq. A roof pitch multiplier also known as a roof pitch factor is a number that when multiplied by the area covered by a sloped roof gives the actual area of the roof. If you need to find out the area of the roof such as to purchase roofing knowing and using the factor will assist you greatly in determining the exact square footage. The maths behind this number is that it is the square root of rise run 2 1.

For roof slopes expressed as x in 12 rise in run the roof pitch multiplier is determined by finding the square root of rise run 1. The everseam profile from everlast roofing inc will fit your home with high quality pre painted roof panels with an attractive style that enhances the appearance of your property. To obtain an accurate roof pitch measurement properly measure the rise and run. The roof slope factor chart also consists of conversion factors to determine the slope of the roof.

A roof pitch multiplier also called a roof pitch factor is a number that is multiplied by the area covered by a sloped roof to produce the area of the actual surface of the roof. The roof slope factor is written as x 12 where x is the vertical distance you measured from roof to level. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. Roof pitch is a term describing how steep or flat your roof slope is.

Then you ll be able to measure slope from an unfinished attic space under the roof. The combination of two numbers are used to display or show the roof pitch. For instance if the measurement was 3 your roof slope factor would be 3 12 and. Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.
