# Home Improvement: Learn How to Calculate Roofing Squares

There are different ways on how to calculate roofing squares. The most popular way is called the old-fashioned calculation, which uses a quadrant, or square, and the area of the house divided by the sum of its exterior wall cells. A more accurate calculation would be to use a perimeter wall calculator. Using this method, you divide the exterior wall cells by their row widths, then multiply the result by the number of exterior wall cells. The result is the square footage of the house.

The cost per square foot, includes the cost of the building materials used. It also takes into account the labor costs. You can calculate roofing squares by using the cost per square foot calculator. This calculator can help you determine the per square footage cost of asphalt shingles. The cost per square foot for asphalt shingles is the same as for vinyl shakes. Once you have determined how much it will cost to install the material, you need to determine how many square feet it will take to cover the entire area of your home.

In order to learn how to calculate roofing squares, you must first understand the difference between square feet and porosity. A square foot is one sixth of an inch, so the actual measurement will not be exact. A greater degree of porosity means that more area of the roof is covered with asphalt shingles, which will lower the cost per square foot.

If you are wondering how to calculate roofing squares to determine how many of these square footage of your home you will need to cover with asphalt, you can also learn how to calculate the number of exterior concrete walls you need to cover. For the purposes of this example, assume that your home has four exterior walls. This number will be the number you need in order to calculate how many square feet of asphalt you will need to cover the exterior walls. After you have determined how many exterior walls you will need to cover, you can multiply that number by the amount of interior square footage of your home in inches.

Knowing how to calculate roofing squares will help you choose the best type of shingle for your home. For example, if you live in a home with a large exterior area, you should use asphalt shingles. On the other hand, if your home has very little or no exterior area, vinyl shingles should be used.
