How to Use This Calculator
Start on the Quick Estimate tab to get a ballpark cost in seconds. Enter your total roof area (the average US home is about 2,000 sq ft of roof), choose your preferred material, and select your roof pitch and complexity. The calculator instantly produces a low-to-high cost range that includes materials, labor, and basic accessories like underlayment and flashing.

For a precise budget, switch to the Detailed Estimate tab. Here you can specify whether tear-off is needed (and how many layers), estimate decking repair as a percentage of total area, add permit costs, and select your state for regional labor adjustments. The output breaks down every line item so you can see exactly where each dollar goes — materials, labor, tear-off, decking, and permits.

Use the Compare Materials tab to see all major roofing materials side by side for your exact roof size. This is especially useful if you are debating between asphalt and metal, or considering a premium material like slate. Toggle lifecycle cost to compare not just installed price but cost per year over each material's expected lifespan — a $40,000 slate roof at 100+ years can actually cost less per year than a $10,000 asphalt roof replaced every 25 years.

The Formula
Quick Estimate = Roof Area x Material Cost per sq ft x Complexity Multiplier Complexity Multiplier: Simple = 1.0, Moderate = 1.15, Complex = 1.35 Tear-Off Cost = Roof Area x Tear-Off Rate (single: $1.00-1.75, double: $1.50-2.50) Decking Repair = Roof Area x Repair % x $4.50/sq ft (material + labor per sheet) Permit Cost = Flat fee $150-500 depending on jurisdiction State Adjustment = Base Cost x Regional Multiplier (0.85 to 1.40) Lifecycle Cost per Year = Total Installed Cost / Expected Lifespan in years Total Cost = Materials + Labor + Tear-Off + Decking Repair + Permits
Example Calculation
For a 2,000 sq ft moderate-complexity roof with architectural shingles in Ohio:
• Material + labor base: 2,000 x $5.75 = $11,500
• Complexity multiplier: $11,500 x 1.15 = $13,225
• Tear-off (1 layer): 2,000 x $1.25 = $2,500
• Decking repair (10%): 200 sq ft x $4.50 = $900
• Permit: $250
• State adjustment (OH = 0.95): ($13,225 + $2,500 + $900 + $250) x 0.95 = $16,031
• Total estimate: $16,031 (range: $13,500-$18,500)
• Lifecycle cost: $16,031 / 30 years = $534/year

Frequently Asked Questions

How much does a new roof cost in 2026?
The average new roof in the US costs $9,000-15,000 for asphalt shingles on a typical 2,000 sq ft roof in 2026. This includes tear-off, materials, labor, and permits. Budget 3-tab shingles start around $3.50-5.50 per sq ft installed, architectural shingles run $4.50-7.00, standing seam metal costs $9.00-16.00, and natural slate can reach $18.00-40.00 per sq ft. Your final price depends heavily on roof size, pitch, complexity, and regional labor rates.
What factors most affect new roof pricing?
The five biggest cost drivers are: (1) Roof size — every additional 100 sq ft adds $350-1,500+ depending on material. (2) Material choice — slate costs 4-8x more than basic asphalt. (3) Roof complexity — a steep hip roof with dormers costs 30-50% more than a simple gable due to extra labor, flashing, and waste. (4) Location — labor rates in the Northeast and West Coast run 25-40% higher than the Southeast or Midwest. (5) Tear-off — removing existing layers adds $1.00-2.50 per sq ft.
When should I replace my roof instead of repairing it?
Replace rather than repair when: your roof is past 80% of its expected lifespan (17+ years for 3-tab, 22+ for architectural shingles), more than 25% of shingles are damaged or missing, you see daylight through the decking, there are multiple active leaks, or the deck feels spongy underfoot. As a rule of thumb, if a repair would cost more than 30% of a full replacement, replacement is the better investment.
Can I finance a new roof?
Yes. The most common financing options in 2026 are: (1) Roofing contractor financing — many large companies offer 12-60 month plans at 0-12% APR. (2) Home equity loan or HELOC — typically 6-8% APR with tax-deductible interest. (3) Personal loan — 7-15% APR, no collateral required, funds in 1-3 days. (4) FHA Title I loan — government-backed improvement loan up to $25,000. (5) Insurance — if damage is storm-related, your homeowners policy may cover most of the cost minus deductible.
How is a new roof cost calculator different from a roof replacement calculator?
A new roof cost calculator covers the full scope of putting a roof on a structure — including new construction where no previous roof exists, as well as full replacements. It factors in structural considerations like decking, permits for new builds, and material selection from scratch. A roof replacement calculator focuses specifically on swapping an existing roof and emphasizes tear-off logistics and matching existing conditions. Use this calculator when you are budgeting from scratch or comparing all material options for a major project.
