Silicone roof coatings and TPO roofing systems each excel in different scenarios. Whether you’re managing an aging flat roof or designing a new commercial building, choosing the right system depends on your goals, climate conditions, and project constraints. Here’s where each option is most commonly used—and why.
Commercial Buildings with Existing Flat Roofs
Silicone Coatings:
Ideal for restoring flat and low-slope commercial roofs that are weathered but structurally sound. Silicone adds a seamless, waterproof barrier without needing a tear-off, making it perfect for roof rejuvenation.
TPO Roofing:
Used when the existing roof has reached the end of its life or when structural repairs are needed. TPO is often selected for a full membrane replacement or in cases where insulation upgrades are required.
Facilities Needing Quick, Cost-Effective Restoration
Silicone Coatings:
Silicone shines in restoration projects. It can be applied directly over the existing surface, significantly reducing time, labor, and material costs. It’s ideal for busy facilities that can’t afford major operational interruptions.
TPO Roofing:
More labor-intensive and disruptive, making it better suited for scheduled capital improvement projects with flexibility for tear-off and extended timelines.
New Construction Projects Requiring Membrane Systems
TPO Roofing:
The go-to choice for new commercial construction due to its long lifespan, energy efficiency, and compatibility with various insulation systems. It offers a clean, durable finish and meets modern code requirements.
Silicone Coatings:
Rarely used in new builds, as they are designed to restore and seal existing roofing materials rather than serve as standalone systems.
Regions with Frequent Rainfall or Ponding Issues
Silicone Coatings:
Outperforms other options in wet climates or where ponding water is a concern. Silicone’s hydrophobic properties make it one of the few materials that can resist long-term standing water without degrading.
TPO Roofing:
Water-resistant but not ideal for roofs with ongoing ponding problems unless paired with upgraded drainage systems or roof slope corrections.
Hot Climates Demanding High UV Reflectivity
Both Systems:
Offer excellent reflectivity and energy efficiency.
Silicone Coatings: Maintain UV performance longer with minimal cleaning and resist chalking.
TPO Roofing: Starts with high reflectivity but may require periodic maintenance to retain its cooling performance.
Buildings with Limited Access for Tear-Off and Replacement
Silicone Coatings:
Perfect for locations where a tear-off is difficult or disruptive—like hospitals, retail centers, or manufacturing plants. The lightweight, no-demolition application is ideal for tight spaces and operational facilities.
TPO Roofing:
Requires more equipment and space for materials, making it better for sites with easy roof access and minimal sensitivity to construction activity.
Conclusion:
Choose silicone for fast, cost-effective restorations on aging roofs, particularly in wet or high-UV climates. Choose TPO for new builds or complete replacements where long-term membrane performance and insulation upgrades are priorities.
