However shingles are packaged in a way that they are light enough for the average person to carry around.
Figure squares shingles roof.
The calculator cannot account for complex shapes based on a measurement of square footage alone.
That is the roof s rise.
The run always remains constant at 12 inches.
Conventional slope roof range between 4 in 12 and 8 in 12.
The answer is the number of roofing squares for the roof.
1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square.
There are two main categories of roofing.
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.
As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles.
A square of shingles is the number of shingles needed to cover 100 sq feet of roof area.
Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.
Roof slope style.
A flat roof has a slope of 2 in 12 or less.
Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing.
Convert the area to roofing squares.
