Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing.
Roof area reroof 100 sq ft.
To accurately calculate the area of your roof you must first determine its slope or pitch.
Or 450 per square to replace an asphalt shingle roof on a typical single family house.
Roofing cost per square foot.

To do that simply multiply drainage area calculated earlier by roof pitch factor and rainfall intensity.
After you have calculated the square footage use following calculations.
For a 5 inch k style gutter the square footage should be up to 5 500 sq ft and for a 6 inch k style gutter the square footage should be upto 7 900 sq ft.
A square of shingles is the number of shingles needed to cover 100 sq feet of roof area.
The calculator cannot account for complex shapes based on a measurement of square footage alone.
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.
The average roof is 3 000 square feet or around 30 squares.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
Many homes have an asphalt shingle roof but some have wood metal tile and slate which can be more expensive.
