Super Therm roof coating is a white, reflective coating designed to reduce heat absorption, lower cooling costs, and extend roof life. This guide explains how the product works, its benefits, application steps, and what to consider when evaluating it for a building in the United States. By understanding the science behind reflective coatings and their long-term value, property owners can make informed decisions about energy efficiency and roof maintenance.
What Is Super Therm Roof Coating
Super Therm roof coating is a polymer-based, reflective coating that creates a bright white, durable membrane on various roof substrates. It uses micro-encapsulated particles to reflect solar radiation and reduce heat transfer into the structure. The formula often includes UV stabilizers and elastomeric compounds that allow for temperature fluctuations and weathering. It is commonly applied over metal, concrete, modified bitumen, or existing coatings, providing a seamless, weather-resistant barrier.
How It Works For Energy Efficiency
During hot months, a portion of the sun’s energy becomes heat that transfers into buildings. A reflective roof coating minimizes this heat gain by reflecting a high percentage of solar radiation. This reduces indoor temperatures, lowers air conditioner load, and can significantly cut monthly energy bills. In cooler seasons, the coating can contribute to minor heat retention, depending on climate and roof insulation, while maintaining protection against moisture and hail. The overall effect is a cooler interior and more stable comfort levels.
Key Benefits Of Super Therm
- Energy Savings: Lower cooling costs due to reduced heat absorption on roofs with high reflectivity.
- Extended Roof Life: Elastomeric properties resist cracking and weathering, helping seal leaks and protect membrane integrity.
- UV Protection: UV stabilizers slow degradation from sun exposure, preserving color and performance.
- Water Resistance: The coating forms a waterproof layer that reduces moisture infiltration and corrosion on metal roofs.
- Environmental Impact: Lower energy use translates to reduced greenhouse gas emissions from HVAC systems.
Application Process And Best Practices
Application quality determines the coating’s effectiveness and longevity. Surface preparation is essential and often includes cleaning, removing debris, repairing cracks, and ensuring a dry substrate. Priming may be used on porous surfaces to improve adhesion. The coating is typically applied with rollers, brushes, or spray equipment, and may require multiple coats to achieve the desired thickness and coverage. Temperature and humidity guidelines should be followed to prevent improper curing. A professional crew will verify adhesion, seam integrity, and cure time before returning the roof to service.
Durability, Maintenance, And Lifespan
Super Therm coatings are designed for flexibility and weather resistance. When properly applied, they resist ponding water on flat roofs and tolerate thermal cycling without cracking. Maintenance includes periodic inspections after severe storms, cleaning to remove dirt and debris that could reduce reflectivity, and recoating at intervals recommended by the manufacturer or contractor. The typical lifespan ranges from several to more than a decade, depending on roof substrate, climate, maintenance, and adherence to cure times.
Cost Considerations And Return On Investment
Costs for Super Therm roof coating depend on roof size, substrate, accessibility, and local labor rates. While upfront expenses may be notable, homeowners and property managers can realize a favorable return on investment through energy savings, extended roof life, and reduced maintenance. A typical ROI analysis compares annual cooling costs before and after application, accounting for climate zone, insulation quality, and energy prices. Financing options or utility rebates may also influence the overall cost-effectiveness of the project.

Comparing With Other Roof Coatings
Several roof coatings offer reflective properties, including acrylic, silicone, and polyurea products. Super Therm stands out for its emphasis on high reflectivity, elastomeric durability, and compatibility with diverse substrates. When evaluating options, consider:
- Reflectivity (Solar Reflectance Index, SRI) and emissivity
- Durability under UV exposure and weathering
- Flexibility to accommodate roof movement and temperature swings
- Ease of application, cure time, and maintenance requirements
- Compatibility with existing roof materials and warranties
Environmental And Health Considerations
Reflective roof coatings like Super Therm can contribute to urban heat island mitigation by lowering rooftop temperatures. Reduced energy consumption lowers emissions associated with electricity generation. It is important to ensure proper ventilation and ventilation during application when using solvent-based formulations. Choosing low-VOC or water-based variants can minimize indoor air quality concerns during installation and curing.
Choosing A Qualified Contractor
Selecting an experienced contractor ensures proper surface preparation, coating thickness, and curing. Request case studies, technical data sheets, and proof of licenses and insurance. Ask for a written application plan, coating conversion rates, and a warranty outline. A reputable contractor will provide a pre-work assessment, detailed scope, and post-application inspection to verify adhesion, cure, and performance.
Maintenance Tips To Maximize Performance
- Schedule routine roof inspections after heavy rain or hail to detect damage early.
- Keep gutters clear to avoid standing water that can compromise the coating’s performance.
- Avoid power washing at high pressure near the coating to prevent surface damage.
- Plan for re-coating cycles aligned with manufacturer guidelines to sustain reflectivity.
Frequently Asked Questions
Q: How long does Super Therm take to cure? Cure times vary by product and climate, typically ranging from several hours to a day for initial set, with full cure over several days.
Q: Can Super Therm be applied over existing coatings? In many cases, yes, provided the current surface is sound, clean, and compatible. Surface preparation is critical for adhesion.
Q: Is it reflective in all climates? The coating remains highly reflective in temperate to hot climates, though local solar exposure and maintenance influence long-term performance.
