Perhaps you came across the phrase "how to calculate roofing squares" while researching roofing costs and another roofing lingo. Right?

We recognize that attempting to grasp all of the roofing jargon may be a daunting task. This is true when it comes to the essential terms that you must comprehend while reviewing the estimate for your new roofing.

The word "roof square" is one of the most essential of them. But what exactly is it, and why is it important to know?

What exactly is a Roofing Square?

A variety of variables determines your roofing cost. The size of your roof, which is determined by a measurement known as a "roofing square," is one of the most important considerations.

A roofing square is a 10x10 space that is equivalent to 100 square feet of roof surface. The number of roof squares impacts the number of roofing materials and labor required to replace your roof.

The greater the number of squares on your roof, the greater your roof replacement expenses. Typically, it takes roughly a dozen packages of roofing materials to fill a roofing square completely.

So, how do you figure out how many roofing squares you need? Continue reading to find out more.

The 3 Steps On How To Calculate Roofing Squares

Now it's safe to say that you're familiar with a roofing square. The number of materials, work, and time needed to construct a roof is directly impacted by the number of roof squares.

There's nothing better than knowing how much a roof will cost per square foot before deciding whether to buy or repair one. To get a preliminary number for the cost of your roof installation, we use an effective technique for calculating the square footage of your roof.

1. Calculate Your Home's Building Footprint

Using your home's square footage gives you a rough estimate of your roof's square footage. Determining your home's building footprint is necessary. A person of average height will stride 2 to 2.5 feet. 

To get your house's footprint, count the steps you walk to get the length of your home. You will then leave your home's breadth. The footprint of your house is calculated by multiplying the length and breadth of your home.

Building Footprint=Length x Width

While your estimates will be wrong, this method might give you an idea of your home's building footprint. Remember that a house's square footage does not equal a roof's.

2. Always Consider Your Roof's Slope And Intricacy

When calculating the square footage of your roof, bear in mind its composition. The slope and intricacy of your home's footprint will modify the number.

Such as:

The square footage of a walkable gable roof is calculated by multiplying the roof's footprint by 1.3.

For a hip roof with a modest slope, you'll multiply the roof's footprint by 1.4 to acquire the square footage of your roof.

To obtain the roof's square footage for a steep and complicated roof, increase the footprint by 1.6.

3. Calculate Your Roof's Square Footage

After examining your roof's slope and intricacy, you're ready to learn how to determine its square footage.

To determine your roof's square footage, apply the following equation:

(home length) x (home width)=(footprint of your home)

(house footprint) x (slope and intricacy)=(square feet of roof area)

Here is an example. For a 56-foot-long, 28-foot-wide home with a walkable gable roof, your computation would be:

56' x 28'=1,568' (footprint of your home)

2 x 1,568 (for a walkable gable roof)=2,038 (square feet of roof area).
