Explore the concept of what a square is in roofing and a comprehensive roofing checklist for 2025. Discover all you need to know about roofing squares, their size, and how they’re calculated to ensure a successful project.
What Is a Square in Roofing?
The term “square” in roofing is an industry-specific measure of area. It does not refer to the geometric shape but to a unit of measure used by roofing professionals to streamline the estimation, ordering, and installation process.
Definition of “Square” in Roofing
In roofing terms, a “square” refers to an area of roof covering 100 square feet. The term got its roots from the more complicated process of calculating roofing materials, which often involved taking square roots. To avoid confusion, the industry adopted the term “square” to streamline the process.
Size of a Square in Shingles and Other Roofing Materials
To provide a clearer understanding of a roofing square size, let’s consider different materials:
- Asphalt Shingles: Three bundles of standard asphalt shingles cover one square foot, equivalent to approximately 100 square feet.
- Metal Roofing: The size of a square for metal roofing can vary depending on the panel size and style. However, coverage remains around 100 square feet.
- Tile: The number of tiles needed to cover a square can greatly vary depending on tile size. However, the coverage area is still calculated as 100 square feet per square.
How Roofing Squares Are Calculated
Roofing squares are calculated by dividing the total roof area by 100. You can measure the length and width of each section of your roof, multiply those numbers to get the area, add each section’s area, and then divide by 100 to get the total number of squares.
Conversion of Roofing Squares to Other Measurements
One roofing square equals 100 square feet. So, if your roofing contractor says your roof is 20 squares, your roof area is 2,000 square feet.
This knowledge can help homeowners have an informed conversation with their contractors and better understand the process of estimating the quantity of roofing materials required for their roofs.
Roofing Squares and Terminology
There are two main terms related to squares that are used in the industry:
- Bundles: This term refers to a package of shingles. Three bundles make up a square of standard asphalt shingles.
- Coverage: This term refers to the area that a certain quantity of roofing material will cover when properly installed. For instance, a bundle of shingles may have a coverage of 1/3 of a square, meaning three bundles are needed to cover a full square.
Application of Roofing Squares in Estimating and Installation
Roofing squares are used in all stages of roofing, from estimation to installation. When estimating, a roofer determines the total squares on a roof to understand how much material will be needed. Manufacturers often sell roofing materials by the square, making it easy to order exactly the right amount once the number of squares has been determined.
Learning the concept of roofing squares and its application is crucial to comprehending a roofing job’s scope, cost, and requirements. It also allows homeowners to communicate more effectively with roofing professionals and ensures transparency in material costs and labor estimates.
