# How To Calculate Roofing Squares

A question that home owners have often asked is how to calculate roofing squares. There is a simple answer and a more complex answer to this question, depending on the type of shingle used and the amount of square footage to be covered. This article briefly covers the basics of how to calculate roofing squares. The purpose of this article is to provide an easy explanation of a basic calculation that most home owners should know and understand.

Most home owners know that asphalt shingles are measured from one to four hundred feet on either side. However, there is a more precise way to measure the length of the shingles. The NACE (National Association of Certified Appraisers) and Snell are two of the leading associations in the U.S. that recommend a minimum of five hundred feet for square footage. One thing that may be confusing is that these two organizations do not recommend using more than seven hundred square feet. This is because of the issue of square footage when it comes to determining the cost of a roof.

When you learn how to calculate the cost of a new roof, you will soon see that the amount of square footage that is covered by shingles is directly related to the cost per square foot. For instance, asphalt shingles that measure one hundred feet by fifty-eight feet are going to cost less than those that are measured at one hundred feet by three hundred feet. However, it will cost less than those that are two hundred feet by six hundred feet.

Asphalt shingles come in many different shapes and sizes, which give home owners a wide range of options when they are trying to learn how to calculate roofing squares. One way to learn the number of square feet needed to cover a particular area is to take a measurement from the outside of the home. This should include the length, width, and height. Then multiply this figure by the number of square feet that you need for your roof. You will need to know the cost of installing the roof so you will need to subtract this from the cost per square footage.

A final way to calculate square footage is to multiply the cost per square footage times the total number of feet that it takes to install the roofing system. This will give you an approximation of how long it will take you to complete the project. In order to get a more accurate figure, you will need to determine how many feet the new roof will cover. Add this to the square footage figure from before and you will have the exact amount of square footage that you need. Then you simply divide the total cost by the number of feet so that you get the exact dollar amount. This can be an effective way to calculate costs for all types of roofing systems.

When learning how to calculate roofing squares keep in mind that the calculation can change depending on the type of square footage that is used. For example, if you use a single six-foot square footage then you will need to add a half inch onto that figure for your final cost. Keep in mind that when doing these estimates that you will most likely not be using the actual square footage. Most estimates are merely a best guess as to what the cost will actually be based on current conditions. However, if you need exact figures you will need to go online and visit a site that offers an online calculator.
