What is a Roofing Square?

Did you overhear a roofer saying the word "roofing square" or simply want to know what a roof square means? You're in the right place! We'll go over exactly what the roofing term "roofing square" is and additional insights to educate you further.

What is a Roofing Square?

A roofing square refers to a standardized measurement used in the roofing industry, representing an area of 100 square feet. In simple terms, it’s the equivalent of a 10-foot by 10-foot section of a roof.

Why are Roofing Squares Used Instead of Just Square Feet?

Measuring in roofing squares keeps the numbers smaller and easier to handle for contractors. It would be much more difficult to discuss the size of a roof in terms of individual square feet. Measuring in roofing squares also makes buying materials quicker and more efficient for roofing experts. Lastly, using roofing squares also helps eliminate waste or overbuying materials.

How Big is a Roofing Square Exactly?

As mentioned earlier, a roofing square measures 10 feet by 10 feet, totaling 100 square feet. You could compare a roofing square to a small shed or even a smaller room.

How to Calculate How Many Roofing Squares You Need

Knowing the number of roofing squares your home has can streamline the estimating process and provide a clearer understanding of the costs associated with repairs or replacements.

The Easy Formula

Divide the total square footage of your roof by 100. For example, if your roof is 2000 square feet, you would divide 2000 by 100, which equals 20 roofing squares.

Measuring Your Roof (Brief Overview)

To figure out the total square footage, each section of your roof needs to be measured for length and width, then those areas are added together. We recommend having a roofing pro take care of the measurements. They have the right tools and experience to get it done safely and accurately, especially if your roof is steep or has a unique design.

Using Roofing Squares to Estimate Shingles and Other Materials

Roofing materials like shingles, underlayment, and flashing are often sold by the roofing square. For example, a bundle of shingles might cover 1/3 of a roofing square. Knowing the number of squares on your roof helps you determine how much of each material you'll need.

Also, it is a good idea to add about 10-15% more for a "waste factor." This accounts for any cuts, overlaps, and mistakes during the installation.

How Roofing Squares Relate to the Cost of Your Roof

Your roofer's estimate will likely be based on the number of roofing squares needed. But remember, other factors play a role in the final cost, too, including the type of materials, labor, and the complexity of your roof's shape.

Conclusion

A roofing square is simply a 100-square-foot area on your roof that is commonly used by roofers to make the process of providing quotes and ordering materials easier.
