A roofing square is 100 square feet. This is the standard unit roofers use to measure roof size and cost. If you have a 1,700 square foot roof, that equals 17 squares. Understanding squares helps you get accurate quotes and know what you are paying for.
What Is a Roofing Square?
A roofing square equals 100 square feet. Roofers do not measure roofs in just feet. They use squares to make math easier and faster.
One square covers a 10 by 10 foot area. Most homes need between 15 and 30 squares. According to the National Association of Home Builders, the average U.S. roof size is 2,647 square feet or 26.47 squares.

How Do Roofers Calculate Roof Squares?
To find your roof squares, measure your roof length and width. Multiply length times width to get total square feet. Then divide by 100.
For example, a 1,700 square foot roof equals 17 squares. A 3,000 square foot roof equals 30 squares. Roofers use this number to give you pricing and material estimates.
What Does Roof Square Mean for Cost?
Roofing costs are quoted per square or per square foot. According to RubyHome, roof installation costs range from $4 to $40 per square foot. This means one square (100 sq ft) costs $400 to $4,000.
Here is how material costs break down per square:
| Material Type | Cost Per Square Foot | Cost Per Square (100 sq ft) |
|---|---|---|
| Basic Asphalt Shingles | $4.25, $4.95 | $425, $495 |
| Architectural Asphalt | $4.50, $8.25 | $450, $825 |
| Metal Roofing | $5.50, $17.05 | $550, $1,705 |
| Clay Tiles | $12.00, $24.75 | $1,200, $2,475 |
Average Roof Size and Total Cost
Most U.S. homes have roofs between 1,200 and 3,000 square feet. According to RubyHome, the average roof replacement cost is $9,526, with a range of $5,868 to $13,217 for typical homes.
For a 1,700 square foot roof (17 squares), you can expect to pay $6,800 to $68,000 total depending on material choice. Asphalt shingles cost less. Metal and tile options cost more but last longer. According to industry data, asphalt shingles last 20 to 30 years, while metal roofs last 40 to 80 years.
Knowing your roof squares helps you budget correctly and compare quotes from different roofers fairly.
