Once you know this number you can estimate the final price of the materials.

Figuring roof area on 5 12 roof.

The rise is the distance from the top of a stud wall to the peak of the roof. Roof pitch area multipliers. Once you have your roof s pitch divide the number by 12. Calculating the area true if you want to get the exact area measurement for your roof you can follow these steps.

You will need to express this size in terms of square feet. Calculate or enter the square footage of the attic or area to be vented. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. For example a 4 12 pitch roof that is 100 square feet.

If your number is 1 3 squared would yield 1 9. The pitch of the roof is the rise over a 12 inch run. Let owens corning roofing help you calculate exactly how much ventilation you will need for a healthy and balanced attic with our 4 step ventilation calculator. The first step in a free roofing estimate is measuring the roof dimensions.

Find the area of a roof. Keep in mind that the average size of a roof is 1 700 square feet so your total will likely be 10 higher or lower than this figure. Thus a moderate 6 in 12 roof pitch means the roof rises 6 inches for every 12 horizontal inches it runs. Dividing by 12 gives the ratio of inches in rise per distance.

This would yield 1 3 next square your result. A roof s pitch is determined by how much it rises for every foot it runs. For example you will need to figure out the exact number of shingles required to cover the entire roof area. 100 1 054 105 4ft 2.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Roof pitch is given as the number of inches in height change over the distance of one foot. While it is possible to estimate the amount of necessary materials using only the total roof area measurement as can be seen from the table depending how large the pitch of the roof the actual area of the roof can differ by up to 2 236 from the measured total area at a pitch of 24 12. A 12 in 12 pitch is a steep 45 degree angle roof.

Once the area is known divide by the area of a 4 8 sheet to find how much sheathing is needed.
