When Should You Choose Siloxane Over Elastomeric Based on Cost?

When protecting your roof from water intrusion, UV damage, and weathering, both siloxane and elastomeric coatings offer unique benefits. Our Siloxane vs. Elastomeric Roof Coating Cost Calculator is designed to help contractors, building managers, and homeowners evaluate these options side-by-side using square footage, material pricing, labor rates, and coating lifespan.

How to Use the Siloxane vs. Elastomeric Calculator | Step-by-Step Process

Step 1: Define Project Specs

Enter your roof area (sq ft) and assess its current condition level.

Step 2: Fill in Cost Inputs for Each Coating

For each type (Siloxane and Elastomeric):

- Enter material cost per sq ft and desired thickness in mils.
- Input labor rate per hour and application time.
- Define coating lifespan and yearly maintenance cost.

Step 3: Generate and Compare Results

The calculator will estimate:

- Total installation cost (material + labor)
- Annual cost of ownership based on lifespan and maintenance
- Helpful for bid comparisons and ROI analysis

Key Cost Elements in the Coating Calculator

1. Roof Area and Surface Condition

Begin by entering your roof size in square feet.
Select the surface condition (e.g., good, minor cracks, significant prep) to influence labor and primer costs.

2. Coating Type and Thickness

Input material cost per sq ft for both siloxane and elastomeric coatings.
Enter the desired thickness in mils — thicker applications may extend lifespan but raise costs.

3. Labor, Longevity & Maintenance

Input labor rate per hour and hours per 100 sq ft to apply each system.
Enter lifespan in years and annual maintenance cost per sq ft.
Siloxane coatings tend to offer excellent water repellency and breathability; elastomerics excel in flexibility and bridging cracks.

Making the Right Coating Decision

Siloxane coatings are ideal for masonry and vertical surfaces but are gaining ground for select roofing systems with high water exposure.
Elastomeric coatings are better suited for horizontal, flexible surfaces with temperature cycling.
Use this calculator to compare siloxane vs elastomeric roof coating cost, durability, and lifecycle efficiency.

Our Siloxane vs. Elastomeric Roof Coating Cost Calculator uses verified 2026 industry pricing standards and is optimized for custom building configurations or regional adjustments.

Choosing the Right Roof Coating for Long-Term Protection
