Next find the square footage of the metal roofing panels you want to use.

We plan to enable the use of fractions at a later time.
For example standing seam metal roofing is 24 inches wide.
Divide the length of your roof by the width of the metal.
Multiply the footprint square footage by the multiplier for your roof pitch to find the actual square footage of the roof.
You will need to express this size in terms of square feet.
This is simply 100 square feet of roof.
Outside of the u s a degree angle is typically used.
Enter square footage calculate or enter the square footage of the attic or area to be vented.
Measure the length and width in feet then multiply together to find the square footage.
In our example we will use 24 inch standing seam roofing so we will divide 360 inches by 24 which equals 15.
This will determine the amount of roofing material you need.
Finding the size of the roof in squares.
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.
For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches.
Enter the diameter of the roof ridge vent gap 1 3 finally enter the coverage area width of the panels you plan to buy.

Let owens corning roofing help you calculate exactly how much ventilation you will need for a healthy and balanced attic with our 4 step ventilation calculator.
A square simply refers to a 10 x 10 square of roofing.
Roofing contractors estimate projects and materials by the square so it is crucial to find this measurement to accurately estimate the amount of material needed.
Step 5 multiply the total width by the total length for the total roof area.
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.
How to figure metal roofing to use this panel length calculator enter whole numbers and decimals only.
A typical 120 foot long roof edge with 6 12 overhangs and no gutters deicing will need about 291 feet of cable.
Step 6 divide the total roof area by the width of the metal roofing material you intend to use.
