To charge for roofing per square, you need to calculate the total square footage of the roof, divide it by 100 to get the number of squares, and multiply that by your per-square price. A square in roofing is 100 square feet, which is the standard unit contractors use for pricing. Most roofing materials cost between $4 and $40 per square foot, depending on the type. According to RubyHome (2025), roof installation costs range from $4 to $40 per square foot. For a 1,700 square foot roof, total costs could be $6,800 to $68,000. Understanding this pricing model helps you quote jobs accurately and compete fairly in your market.
What Is a Roofing Square?
A square is the basic unit of measurement used by roofers across the country. One square equals exactly 100 square feet of roof area.
This standard makes it easy to calculate materials and labor. If a roof is 2,500 square feet, that is 25 squares. Most contractors and material suppliers use this term when discussing pricing and estimates.

How to Calculate Your Per-square Price
Start by finding your total material and labor costs. Add overhead and profit margin to this number.
Divide the total by the number of squares on the roof. According to RubyHome (2025), the average roof replacement cost is $9,526, with a range of $5,868 to $13,217. This tells you what the market expects to pay. Your price per square should be competitive but also cover your actual costs.
For example, if a roof costs $9,526 for 1,700 square feet or 17 squares, that is about $560 per square. According to industry data from RubyHome (2025), architectural asphalt shingles cost $4.50 to $8.25 per square foot installed, which equals $450 to $825 per square.
Material Costs by Square
| Material Type | Per Sq. Ft. | 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 |
| Slate tiles | $12.00-$22.00 | $1,200-$2,200 |
Why Market Rates Matter
Pricing per square must match what homeowners expect to pay. According to RubyHome (2025), DIY can save about 50% in costs but often leads to higher long-term expenses from mistakes.
Many homeowners prefer hiring professionals. According to RubyHome (2025), leaking and storm damage are the top two reasons roofs are replaced, each at 33% of cases. These customers understand the need for quality work and fair pricing. Setting your per-square rate too high will lose jobs. Too low will hurt your profit.
Research your local market to find the right balance. Consider materials used, roof complexity, and labor time per square. Most experienced roofers factor in overhead, insurance, and taxes when setting their per-square rates.
