Roof Square Footage Calculator Satellite

The more indentations extensions and intersecting slopes a roof has in its design the more it can add to the total price.

After measuring the area of the footprint you can estimate the actual roof area based on the angle of the roof. To accurately calculate the area of your roof you must first determine its slope or pitch. A map based area calculator for measuring the square footage of lawns for sod installation or fertilizer rates. A roofing square is equal to 100sf.

Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. The google maps area calculator is not 100 accurate. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. 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.

Shape though two roofs may be the same size there could be a quite a price difference depending on the shape of the roof. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. It is often compared to slope but is not exactly the same. 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 one thing you can zoom in on the roof and use the polygon measuring tool to plot the perimeter of the roof and get a usefully accurate total square footage for flat roofs. 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. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Similarly if you using the area calculator tool to measure a roof with multiple levels you should do the individual section separately.
