If your number is 1 3.
Calculating square footage of sloped roof.
The area calculator can be used to calculate the area of a variety of simple shapes that together can comprise the area of the roof.
If your roof is flat or has no more than a 3 in 12 pitch you can calculate its total square footage by simply multiplying the length by the width.
Next square your result.
For example if your roof s pitch is 4 in 12 you would.
Square the result of step 1.
If the same house had a central roof ridge dividing the roof into two sloping areas each would cover 300 square feet or half the house.
The result is the area covered by the sloping roof.
Steep roofs measure your house at ground level then add in the roof s overhang for greater accuracy.
Get the square footage of roof and divide it by 100 and it will give the number of squares you need and for every decimal number over 3 buy a bundle to achieve the amount of material.
For instance if the roof is 1550 square feet then it is 16 squares.
If you don t want to do a lot of measuring you can use your pitch calculation to get an estimated square footage of your roof.
When calculating square footage for your roof always add at least 10 percent of the total to account for waste.
Straight to the answer divide your roof pitch by 12.
The answer is the number of roofing squares for the roof.
Estimate the pitch of the roof.
Add 1 then take the square root.
So keeping with our roof pitch of 4 this gives us 1 9.
After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually.
1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
Shingles and other roofing materials such as underlayment are typically measured in squares that are 10 feet long and 10 feet wide with each square measuring 100 square feet.
To find the squares divide the overall roof area by 100 and then round up.
This is simply 100 square feet of roof.
Roof pitch is given as the number of inches in height change over the distance of one foot.
Once you have your roof s pitch divide the number by 12.
A square simply refers to a 10 x 10 square of roofing.
Roof pitch calculator roof slope calculator the roof pitch calculator is a convenient online tool you can use to quickly assess the pitch of your roof to determine the length of rafters you need.
The calculator cannot account for complex shapes based on a measurement of square footage alone.
Adding 1 gives us 1 1 9 10 9.
