How Many Feet Is My Roof

We included a roof pitch chart below the 7 12 example image and the calculator below that.

How many feet is my roof.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. If this isn t practical then perform the same measurement on the underside of the roof. It is often compared to slope but is not exactly the same. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.

For example if you measure 12 feet then make the length 12 feet 1 inch or 12 feet 2 inches. The first step in a free roofing estimate is measuring the roof dimensions. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Panels are often measured in inches use our inches to feet conversion calculator to convert to feet.

Add an inch or two depending on your preference for overhang. Convert the area to roofing squares. Step 3 calculate the square footage for symmetrical triangle shaped planes by multiplying the length of the triangle s base longest side by its height the distance from the middle of the longest side to the opposite corner. Keep in mind that the average size of a roof is 1 700 square feet so your total will likely be 10 higher or lower than this figure.

Ventsure rigid roll ridge vent. For example if one roof plane measures 120 feet by 120 feet 120 x 120 14 400 square feet. Measure the length and width in feet then multiply together to find the square footage. 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.

30 lineal feet required. 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. 1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. Finally divide the square footage of the roof by the square footage of the metal roofing panel to find the number of panels needed for your roof.

The answer is the number of roofing squares for the roof. 43 lineal feet required. This number will tell you the total length of metal panels needed. See the image below for more explanation on rise run and pitch.

For instance a 7 12 roof pitch means that the roof rises 7 inches for every. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. For example your roof could measure 12 feet to its peak. You will need to express this size in terms of square feet.
