Elastomeric vs. Roof Coating: Which is Better For ...

Nov 4, 2019

Welcome to Bio-One Atlanta, your trusted partner in the Business and Consumer Services - Cleaning industry. In this comprehensive guide, we will explore the differences between elastomeric coating and roof coating, helping you make an informed decision for your commercial or residential roof.

Understanding Elastomeric Coating

Elastomeric coating is a popular choice for roofs due to its exceptional durability and flexibility. Designed to provide a seamless and protective barrier to your roof, elastomeric coating expands and contracts with changing temperatures, safeguarding your roof against cracks, leaks, and other potential damages. It is suitable for various roof types, including metal, concrete, and single-ply membranes.

One of the key advantages of elastomeric coating is its ability to withstand extreme weather conditions, including heavy rain, strong winds, and UV exposure. By acting as a reflective layer, it reduces the absorption of solar heat, keeping your building or home cooler and reducing energy costs. Elastomeric coating also offers excellent resistance to mold, mildew, and algae, ensuring a clean and healthy environment.

Exploring Roof Coating

Roof coating is another viable option for protecting and enhancing the lifespan of your roof. It is typically made of a blend of polymers, resins, and other additives that create a robust shield against the elements. Roof coating forms a protective layer, preventing water penetration, reducing heat transfer, and prolonging the life of the underlying roofing materials. Similar to elastomeric coating, it can be applied to various roof surfaces.

Roof coating boasts exceptional waterproofing capabilities, shielding your roof against leaks and water damage. It offers resistance to UV rays, preventing premature deterioration caused by sun exposure. Additionally, roof coating can enhance the energy efficiency of your building by reflecting the sun's rays, thus reducing the need for excessive cooling and lowering energy consumption.

The Benefits of Elastomeric Coating

Elastomeric coating offers numerous advantages that make it an attractive choice for roof protection:

  • Flexibility: Elastomeric coating can expand and contract with temperature changes, ensuring long-lasting protection.
  • Seamless Application: It can be applied as a liquid, forming a seamless and uniform coating that eliminates potential weak points.
  • UV Resistance: Elastomeric coating reflects UV rays, preventing roof deterioration and reducing cooling costs.
  • Waterproofing: It creates a watertight barrier, safeguarding your roof against leaks and water damage.
  • Durability: Elastomeric coating offers excellent resistance to cracking, peeling, and other forms of wear and tear, extending the life of your roof.
  • Mold and Mildew Resistance: By inhibiting the growth of mold and mildew, elastomeric coating ensures a healthy and hygienic environment.

The Benefits of Roof Coating

Roof coating is a versatile option with its own set of benefits:

  • Waterproofing: Roof coating provides an effective barrier against water intrusion, preventing leaks and potential damage.
  • Heat Reflectivity: By reflecting heat, it helps regulate indoor temperatures, reducing the burden on cooling systems and promoting energy efficiency.
  • Enhanced Roof Lifespan: The protective coating extends the lifespan of the underlying roofing materials, potentially saving you money on future repairs or replacements.
  • UV Resistance: Roof coating shields your roof against harmful UV rays, which can cause premature aging and deterioration.
  • Easy Application: It can be applied relatively quickly and easily, minimizing disruption to your business or daily life.

Choosing the Right Option

When deciding between elastomeric coating and roof coating, several factors need to be considered:

  • Roof Type: Determine the type of roof you have and ensure the selected coating is compatible with the surface.
  • Climate: Take into account the prevailing weather conditions in your area to choose a coating that can withstand sun exposure, heavy rain, high winds, or extreme temperatures.
  • Budget: Evaluate the cost-effectiveness of each option, considering both short-term and long-term expenses.
  • Desired Lifespan: Assess how long you intend to keep the roof before considering a replacement. Each coating option offers different longevity.
  • Energy Efficiency: Consider the energy-saving potential of the coating, as this can impact your utility bills.

It is recommended to consult with a professional roofing contractor, such as Bio-One Atlanta, who specializes in roof coating applications. They can assess your specific needs, recommend the most suitable option, and ensure a high-quality installation.


Elastomeric coating and roof coating both provide excellent protection for commercial and residential roofs. While elastomeric coating offers exceptional flexibility and mold resistance, roof coating excels in terms of waterproofing and heat reflectivity. With careful consideration of your roofing requirements, climate conditions, and budget constraints, you can make an informed decision that best suits your needs.
