To do roofing estimates, you need to measure your roof size, pick your materials, and calculate labor costs. A roofing estimate tells you how much a new roof or repair will cost before work starts. Getting an accurate estimate helps you plan your budget and compare prices from different roofers. Most estimates take 15 to 30 minutes and should be free. According to RubyHome, the average roof replacement costs $9,526, but prices range from $5,868 to $13,217 depending on your roof size and material choice.
Measure Your Roof Size First
Start by finding your roof size in squares. One square equals 100 square feet. According to the National Association of Home Builders, the average U.S. roof size is 2,647 square feet or 26.47 squares. You can measure from the ground using binoculars or climb safely to measure each section. Write down the length and width of each roof area.
Multiply length times width for each section. Add all sections together. Divide by 100 to get your square count. This number is key to your estimate.

Pick Your Roofing Material
Material costs vary a lot. According to RubyHome, asphalt shingles cost $4.25 to $4.95 per square foot, while metal roofing costs $10 to $17.05 per square foot. Here is a quick cost table:
| Material Type | Cost Per Sq. Ft. | Lifespan |
|---|---|---|
| Basic asphalt shingles | $4.25, $4.95 | 20 years |
| Architectural asphalt shingles | $4.50, $8.25 | 30 years |
| Metal roofing | $10.00, $17.05 | 40, 80 years |
| Slate tiles | $12.00, $22.00 | 60, 150 years |
Calculate Labor and Add Costs
Labor is the biggest cost in most estimates. According to RubyHome, roof installation costs range from $4 to $40 per square foot depending on complexity. For a 1,700 square foot roof, total costs range from $6,800 to $68,000.
Add material cost plus labor cost to get your total. Always ask roofers if their estimate includes removal of old roofing, permits, and cleanup. According to industry data, 85% of roofing activity focuses on replacement, not new construction.
Get Multiple Estimates
Call at least three roofers for estimates. Compare prices, materials, and warranties. Good roofers will visit your home in person. They should check for damage and answer your questions. Ask about their experience and if they carry insurance. According to the National Association of Home Builders, 92% of homeowners view the roof as a top three home improvement priority, so take time to choose the right contractor.
