How to Use the Roof Replacement Cost Calculator
Step 1: Enter Roof Dimensions
Measure the length and width of your roof in feet. The calculator will automatically determine the total square footage.
Step 2: Choose Roof Slope and Material
From the dropdown menu:
- Select the roof slope that matches the pitch of the roof:
- Flat (0/10): No multiplier
- Low (3/10): ×1.2 multiplier
- Medium (5/10): ×1.5 multiplier
- Steep (8/10): ×2.0 multiplier
- Then, pick a roofing material:
- Asphalt Shingles ($3/sq ft)
- Metal ($5/sq ft)
- Tile ($8/sq ft)
- Slate ($10/sq ft)
The slope multiplier accounts for added difficulty and labor based on pitch.
Step 3: Add Labor Costs
Choose how you want labor to be calculated:
- Percentage of material cost (e.g. 30%)
- Fixed cost (a flat dollar amount)
Enter the value that best reflects your typical labor charges.
Step 4: Factor in Additional Costs
For a realistic total, consider:
- Disposal Cost – Price per square foot to remove old roofing
- Additional Costs – Unexpected expenses like permits or fees
- Skylights – $300 per skylight
- Chimneys – $400 per chimney
- Ridge Vent – $10 per foot of ventilation installed
Step 5: View Instant Results

Why Accurate Roofing Quotes Matter
Giving your customer a professional, transparent quote does more than win jobs—it protects your bottom line. With rising material and labor costs, having a structured approach to pricing helps you stay competitive while ensuring every expense is covered.
Plus, showing your customer a detailed breakdown builds trust and lets them know they’re paying for quality work—not guesswork.
Example: Quoting a Medium-Pitch Roof
Let’s walk through an example using the same formula used in the calculator.
Roof Replacement Cost Formula:
Total Cost = (Area × Slope Multiplier × Material Cost) + Labor + Disposal + Skylights + Chimneys + Ridge Vent + Additional Costs
Rick, a roofing contractor, visits a new client and gathers the following details:
- Area: 2,500 sq. ft.
- Slope: Medium (1.5×)
- Material: Asphalt Shingles ($3/sq ft)
- Labor: 30% of material cost
- Ridge Vent: 35 ft.
- Chimneys: 1
- Additional Fee: $300 for permit
- Disposal Cost: $4/sq ft
Let’s calculate:
- Base Cost: 2,500 × 1.5 × $3 = $11,250
- Labor: 30% of $11,250 = $3,375
- Disposal: 2,500 × $4 = $10,000
- Ridge Vent: 35 ft. × $10 = $350
- Chimney: $400
- Permit: $300
Total Estimated Cost:
$11,250 + $3,375 + $10,000 + $350 + $400 + $300 = $25,675
With this estimate, Rick can confidently explain the quote to his customer—backed by a clear formula and real job details.
