Similarly if you using the area calculator tool to measure a roof with multiple levels you should do the individual section separately.
Roof square footage calculator satellite.
A map based area calculator for measuring the square footage of lawns for sod installation or fertilizer rates.
If you re going to use an area calculator you can do this separately for each level of the home to ensure a more accurate calculation.
After measuring the area of the footprint you can estimate the actual roof area based on the angle of the roof.
The google maps area calculator is not 100 accurate.
To accurately calculate the area of your roof you must first determine its slope or pitch.
For instance a 7 12 roof pitch means that the roof rises 7 inches for every.
The more indentations extensions and intersecting slopes a roof has in its design the more it can add to the total price.
A roofing square is equal to 100sf.
Sloped roofs are a little more involved but we can help you figure out the surface area of a sloped roof.
In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.
It is often compared to slope but is not exactly the same.
Shape though two roofs may be the same size there could be a quite a price difference depending on the shape of the roof.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
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.
