Elastomeric vs. Silicone Roof Coating Cost Calculator

If you’re upgrading a flat or low-slope roof, elastomeric and silicone coatings are two of the most popular protective systems. Each offers unique benefits for waterproofing, UV resistance, and longevity. Our Elastomeric vs. Silicone Roof Coating Cost Calculator helps you compare total installation costs, maintenance needs, and lifecycle value to select the most effective solution for your climate and budget.

Key Cost Inputs in the Coating Comparison

1. Roof Area and Surface Condition

  • Start by entering your roof size in square feet.

  • Select the roof’s current condition — ranging from good to extensive repair — to adjust surface prep costs.

2. Coating Type, Thickness & Reflectivity

  • Input the cost per sq ft for both elastomeric and silicone coatings.

  • Define coating thickness in mils, which impacts material usage.

  • Silicone coatings typically offer higher solar reflectance; elastomerics are known for better flexibility and crack-bridging.

3. Labor, Lifespan & Maintenance

  • Add your labor rate per hour and application hours per 100 sq ft.
  • Input system lifespan (years) and annual maintenance cost per sq ft.
  • Silicone often lasts longer with fewer reapplications, while elastomerics are easier to patch and recoatable.

How to Use the Roof Coating Calculator (Step-by-Step)

Step 1: Enter Roof Project Specs

  • Input total roof area.
  • Select the existing surface condition (good, minor repair, extensive prep).

Step 2: Add Material & Labor Data

  • For both coating systems:
    • Enter material cost per sq ft and coating thickness (mil).
    • Input labor rate and application time estimate.
    • Add lifespan in years and yearly maintenance costs.

Step 3: Compare Results

  • The calculator displays:
    • Total install cost for each system
    • Annualized cost per year based on performance and lifespan

Helps decide which system is better for low-slope, commercial, or residential roofs
