Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. Keep in mind that using google earth isn t going to give you a 100 percent accurate reading but it will give you a basic idea of the size of the roof for your calculations for the roofing materials. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. A roofing square is equal to 100sf.

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. To accurately calculate the area of your roof you must first determine its slope or pitch. It is often compared to slope but is not exactly the same.

For instance a 7 12 roof pitch means that the roof rises 7 inches for every. After measuring the area of the footprint you can estimate the actual roof area based on the angle of the roof. Sloped roofs are a little more involved but we can help you figure out the surface area of a sloped roof. 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.

Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Shape though two roofs may be the same size there could be a quite a price difference depending on the shape of the roof. The more indentations extensions and intersecting slopes a roof has in its design the more it can add to the total price.
