Silicone vs. Elastomeric Roof Coatings: A Comprehensive Comparison

Roof Coatings

When it comes to protecting commercial and residential roofs, the choice of coating plays a pivotal role in determining the longevity, efficiency, and durability of the roofing system.

Mule-Hide 100% Silicone Roof Coating and Elastomeric Roof Coatings are two leading solutions, each with its unique benefits and limitations.

This article dives into the differences between these coatings, highlighting the pros and cons of each to help property owners decide the best option for their needs.


Mule-Hide 100% Silicone Roof Coating

As a commercial business owner, maintaining the integrity and functionality of your flat roofing system is paramount.

With numerous options available, selecting the right roof coating can be a daunting task.

However, Mule-Hide 100% Silicone Roof Coating stands out as a superior choice for protecting your commercial property.


  • Durability: Mule-Hide Silicone provides a durable elastic membrane that stands up to harsh weather conditions, including extreme temperatures, UV light, and heavy rainfall.

  • Waterproofing: As a waterproof roof coating, silicone offers excellent protection against leaks and water damage, making it ideal for areas with heavy rainfall.

  • Low Maintenance: Thanks to its inorganic nature, silicone coatings are resistant to mold, mildew, and staining, requiring less maintenance over time.

  • Reflectivity: Mule-Hide's reflective properties significantly increase energy efficiency, reducing cooling costs by reflecting sunlight away from the building.


  • Cost: Silicone coatings can be more expensive upfront compared to other materials, potentially impacting budget considerations for some projects.

  • Slippery When Wet: The surface can become slippery in wet conditions, which may be a safety concern during maintenance.

Elastomeric Roof Coatings

In the quest for a durable and efficient roofing solution, elastomeric roof coatings emerge as a leading option for property owners.

This liquid-applied, innovative solution cures into a durable elastic membrane, offering unparalleled protection against the elements.


  • Flexibility: Elastomeric coatings excel in flexibility, allowing them to expand and contract with the roof without cracking, which is crucial for maintaining integrity over time.

  • Versatile Application: Suitable for a broad range of roofing materials, elastomeric coatings offer a roof restoration coating option for aging roofs, enhancing their lifespan.

  • Energy Efficiency: Like silicone, many elastomeric coatings are reflective roof coatings, helping to lower energy consumption by cooling the building.

  • Cost-Effective: Generally, elastomeric coatings are more affordable than silicone, providing a budget-friendly option for extensive roof areas.


  • Thickness Requirement: Elastomeric coatings may require multiple layers to achieve the desired thickness and durability, potentially increasing labor and material costs.

  • Lesser Water Resistance: While highly effective, they might not match the superior waterproofing capabilities of 100% silicone coatings, especially in standing water scenarios.

Choosing the Right Coating for Your Roof

When deciding between Mule-Hide 100% Silicone and Elastomeric Roof Coatings, several factors come into play, including climate, roof type, and specific roofing challenges.

  • Climate Considerations: For areas with heavy rainfall or ponds of standing water on the roof, Mule-Hide Silicone's superior waterproofing abilities might be the decisive factor. Conversely, in regions with wide temperature fluctuations, the flexibility of Elastomeric Coatings could offer better performance by accommodating expansion and contraction without damage.

  • Roof Type and Condition: Silicone coatings are particularly suited for flat or low-slope roofs where water pooling is a concern. Their ability to create a seamless, watertight layer makes them ideal for such scenarios. Elastomeric coatings, with their versatile application, are a go-to for a variety of roof substrates, offering an excellent option for roof restoration projects.

  • Budget and Maintenance: While silicone might have a higher initial cost, its low maintenance requirements could result in lower long-term expenses. Elastomeric coatings, being more affordable upfront, might require more frequent reapplications depending on the environment and the roof's exposure to elements.

  • Energy Efficiency Goals: Both coatings offer reflective properties that can significantly reduce cooling costs. The choice here would depend on the specific product ratings and how they align with your energy efficiency targets.


Both Mule-Hide 100% Silicone Roof Coating and Elastomeric Roof Coatings offer compelling benefits for protecting and enhancing the performance of commercial and residential roofs.

The decision between them hinges on assessing the specific needs of your property, considering factors like climate, roof architecture, maintenance commitment, and budget.
