Replacing your roof is one of the most important decisions you’ll make as a homeowner — both in terms of investment and long-term protection. But how much does a new roof cost in Dardenne Prairie, Weldon Spring and MO, and what should you expect when budgeting for this major project?
While roofing costs vary based on size, materials, and labor, understanding the key price drivers helps you plan smart and avoid surprises. In this guide, we’ll break down the factors that impact roof replacement pricing, what’s included in a good estimate, and why working with a professional roofing company like Horizon Roofing & Exteriors makes all the difference.

Key Factors That Influence Roof Replacement Costs

Every roof is different, and no two homes in Dardenne Prairie or St. Charles County are exactly alike. That’s why roofing prices can range widely — from affordable asphalt shingles to premium materials like metal or slate.

1. Roof Size and Complexity

Roofing contractors use “roof squares” to calculate pricing. One square equals 100 square feet. So, a 2,000 sq. ft roof equals 20 squares. But size isn’t the only consideration — complex designs with steep slopes, multiple valleys, chimneys, skylights, and dormers drive up labor and waste costs.

2. Roofing Material Choice

Your roofing material significantly affects cost and performance:

  • Asphalt Shingles: Most affordable, widely used, and easy to install
  • Architectural Shingles: Enhanced appearance and durability, mid-range price
  • Metal Roofing: High upfront cost, but long lifespan and energy efficiency
  • Slate/Tile Roofing: Premium option with unmatched longevity
  • Cedar Shake: Natural appearance but higher maintenance

Each option has trade-offs in terms of cost, curb appeal, weather resistance, and longevity. We help you choose the best fit for your home and budget.

3. Labor and Local Installation Standards

Labor typically accounts for 40–60% of the total roofing cost. Your location affects pricing due to:

  • Regional labor rates (Missouri labor is typically more affordable than coastal states)
  • Required permits and inspections
  • Local building codes and weather-related installation methods

Our team at Horizon follows Dardenne Prairie code requirements and Missouri stormproofing best practices to ensure your roof is installed to last.

Roof Repair vs. Full Roof Replacement

Not every roofing issue requires a full replacement. Sometimes, targeted roof repairs are enough — especially after isolated storm damage or small leaks. However, if your roof is over 20 years old, showing widespread deterioration, or has repeated issues, replacement is often the better long-term investment.

A professional inspection can tell you where you stand. At Horizon Roofing & Exteriors, we provide honest, pressure-free roof assessments.

What’s Included in a Roof Replacement Estimate?

A proper roof replacement estimate should include a detailed breakdown of:

  • Material Costs: Shingles, underlayment, flashing, drip edge, ridge vents
  • Labor Costs: Tear-off, installation, cleanup
  • Old Roof Removal & Disposal
  • Permits & Local Compliance Fees
  • Optional Add-ons: Upgraded ventilation, gutter replacement, ice/water shield

We make sure every line item is transparent so there are no surprises.

Common Hidden Costs Homeowners Overlook

  • Additional layers of underlayment or code upgrades
