The Advantages of Using Elastomeric Roof Coatings
Elastomeric coatings are specially formulated to offer flexibility and durability, making them an excellent choice for climates with temperature fluctuations, heavy rain, or intense sunlight. These coatings can expand and contract with the roof’s surface, reducing cracking and peeling.
- Weather Resistance: Elastomeric coatings resist UV rays, wind, and moisture effectively.
- Energy Efficiency: Light-colored coatings reflect solar heat, reducing cooling costs.
- Waterproofing: These coatings create a seamless barrier, preventing leaks and water damage.
- Easy Maintenance: They simplify roof cleaning and prolong the roof’s life without costly replacements.
- Versatility: Compatible with multiple roofing materials such as metal, concrete, and built-up roofing (BUR).
Top Elastomeric Roof Coatings: Detailed Reviews
Henry 887 Tropi-Cool Roof Coating
The Henry 887 Tropi-Cool Roof Coating is a water-based, acrylic reflective coating widely praised for its compatibility with various roof types and excellent adhesive properties. It is especially suitable for flat and low-slope roofs, offering protection against leaks and UV degradation.
Users note its ease of application and impressive energy savings due to its high reflectivity, which helps keep buildings cooler in summer.
Roof Mate Solar 100% Acrylic Elastomeric Coating
Roof Mate Solar is lauded for its superior UV resistance and flexibility. It forms a durable elastomeric film that withstands expansion and contraction caused by temperature changes. This coating is versatile and performs well on metal and flat roofs, delivering reliable waterproof protection.
Liquid Rubber Foundation Coat
Though commonly marketed for foundations, Liquid Rubber’s elastomeric formulation excels on roofs in terms of water resistance and elasticity. Its seamless application makes it ideal for areas prone to pooling water and small cracks.
Black Jack White Elastomeric Roof Coating
Popular in the residential and commercial sectors, Black Jack White provides high reflectivity, reducing heat absorption. The coating resists mold and mildew, helping maintain a clean roof surface, which is especially valuable in humid climates.
GacoRoof Silicone Roof Coating
GacoRoof stands out for its superior ability to handle ponding water without degradation. Its silicone base maintains flexibility and waterproofing in challenging environments, offering long-term protection for metal and silicone-infused roofs.
How to Choose the Right Elastomeric Roof Coating
Selecting an elastomeric roof coating should be based on the following criteria:
- Roof Type: Check compatibility with your roof material (metal, asphalt, concrete, etc.).
- Climate Conditions: Consider UV exposure, rainfall, temperature variations, and humidity.
- Desired Reflectivity: For energy savings, choose coatings with high solar reflectivity.
- Application Method: Some coatings require spray application, others roll-on or brush.
- Durability and Warranty: Longer warranty periods often indicate better product longevity.
Application Tips for Optimal Performance
- Preparation: Clean the surface thoroughly to remove debris, dirt, and old coatings.
- Weather Conditions: Apply coatings during dry, mild weather to ensure proper curing.
- Multiple Coats: Most successful applications involve multiple thin coats rather than one thick layer.
- Protective Gear: Use gloves, masks, and eye protection during application.
- Maintenance: Periodic inspections and touch-ups extend the roof coating’s lifespan.
Common Questions About Elastomeric Roof Coatings
Do Elastomeric Roof Coatings Work on Flat Roofs?
Yes. Flat roofs benefit especially from elastomeric coatings because they provide a seamless waterproof barrier, preventing leaks common in low-slope roofing systems.
How Long Does Elastomeric Roof Coating Last?
When applied correctly, elastomeric coatings can last between 5 and 15 years, depending on factors such as roof condition, climate, and maintenance.
Can I Apply Elastomeric Roof Coatings Myself?
Many homeowners successfully apply these coatings themselves following manufacturer guidelines, but large or complex roofs may require professional installation for optimal results.
Are Elastomeric Roof Coatings Environmentally Friendly?
Most modern elastomeric coatings are water-based, low in VOCs (volatile organic compounds), and help reduce energy consumption, making them an environmentally sound option.
Comparing Elastomeric Coatings and Alternative Roof Sealants
| Feature | Elastomeric Coatings | Bitumen Sealants | Polyurethane Coatings | Silicone Coatings |
|---|---|---|---|---|
| Flexibility | High – accommodates roof movement | Moderate – can crack with extreme temperature | High – very elastic | High – excellent for waterproofing |
| UV Resistance | Good to Excellent | Poor to Fair | Good | Excellent |
| Application | Easy to Moderate (brush, roller, spray) | Moderate (heat needed) | Professional grade – more sensitive | Moderate – often spray or roller |
| Cost | Moderate | Low to Moderate | High | High |
| Lifespan | 5-15 years | 3-7 years | 8-15 years | 10-20 years |
Maintaining Elastomeric Roof Coatings for Longevity
Proper maintenance significantly impacts the durability of elastomeric roof coatings. Regular inspections—preferably twice a year—help identify cracks, blistering, or dirt accumulation. Cleaning with gentle detergents and reapplying touch-up coats when necessary maintains the coating’s integrity and performance.
- Clear debris such as leaves and sticks frequently
- Address ponding water to prevent accelerated wear
- Monitor and repair any localized damage promptly
- Recoat after 5–7 years depending on environmental exposure
Final Thoughts on Elastomeric Roof Coating Reviews
Elastomeric roof coatings remain a highly effective, cost-efficient, and environmentally friendly roofing solution. They provide strong protection against weather elements, enhance energy efficiency, and prolong the life of both residential and commercial roofs. By choosing the right product and applying it correctly, property owners can achieve lasting roofing benefits and peace of mind.
