A square for roofing costs between $400 and $1,500 on average, depending on the material you choose. A roofing square equals 100 square feet. The total cost for your roof depends on how many squares your roof has. Most homes need between 20 and 30 squares. Understanding the cost per square helps you budget for a new roof or repairs.
What Is a Roofing Square?
A roofing square is simply 100 square feet of roof space. Roofers use this measurement to calculate material and labor costs. Your roof size is measured in squares, not just total square feet.
The average U.S. roof size is 2,647 square feet or 26.47 squares, according to the National Association of Home Builders. This means most homes fall between 20 and 30 squares.

How Much Does Each Material Cost Per Square?
Material costs vary a lot. According to RubyHome, basic asphalt shingles cost $4.25 to $4.95 per square foot, which equals $425 to $495 per square. Architectural shingles run $4.50 to $8.25 per square foot, or $450 to $825 per square.
Metal roofing costs more upfront but lasts longer. Here is a quick cost breakdown:
| Material Type | Cost Per Square Foot | Cost Per Square (100 sq ft) |
|---|---|---|
| Basic Asphalt Shingles | $4.25, $4.95 | $425, $495 |
| Architectural Shingles | $4.50, $8.25 | $450, $825 |
| Metal Roofing | $10.00, $17.05 | $1,000, $1,705 |
| Concrete Tiles | $11.00, $19.80 | $1,100, $1,980 |
What About Installation Labor?
Labor adds to the total cost per square. According to RubyHome, roof installation ranges from $4 to $40 per square foot depending on difficulty and location. This means labor costs $400 to $4,000 per square.
Simple roofs with good access cost less. Complex roofs with steep angles or poor access cost more.
How Long Does Each Material Last?
The lifespan affects your long-term cost per square. Asphalt shingles last 20 to 30 years. Metal roofing lasts 40 to 80 years. Concrete tiles last 100 plus years.
According to RubyHome data, asphalt shingles average $446 per square, while steel runs $876 per square. Though steel costs more upfront, it lasts much longer. Most U.S. roofs are replaced at just over 19 years old, according to industry data.
Asphalt shingles dominate about 80 percent of roofing projects in the U.S., according to RubyHome. This makes them the budget-friendly choice. Metal roofing holds about 10 percent market share and is growing fast due to durability and energy savings.
