As energy costs rise and sustainability becomes a business priority, commercial property owners are looking for smarter ways to reduce operational expenses — without sacrificing comfort or protection. One of the most effective solutions is reflective roof coatings.
These coatings not only extend the life of your commercial roof but also significantly lower cooling costs, especially in hot climates like San Antonio and Central Texas. By reflecting sunlight instead of absorbing it, reflective coatings transform your roof into a powerful, passive energy-saving system.
At Rhino Roofers, we specialize in helping Texas businesses make their buildings more efficient through advanced roofing technologies like elastomeric and silicone coatings — proven solutions that keep large buildings cool and protected year-round.
Learn about the various types of reflective coatings that are available during our commercial roof installation services.
What Are Reflective Roof Coatings?
Reflective roof coatings are liquid-applied membranes designed to reflect sunlight and release absorbed heat. Once cured, they form a seamless, protective barrier over the existing roofing system.
These coatings are measured by solar reflectance (how much sunlight they reflect) and thermal emittance (how much heat they release). High-performing coatings can reflect 70–90% of UV radiation, dramatically reducing rooftop surface temperatures.
For commercial buildings with large, flat roofs — like warehouses, offices, and retail centers — this reduction translates to lower indoor temperatures, reduced strain on HVAC systems, and major energy savings.
How Reflective Roof Coatings Save Energy
In Texas, rooftop temperatures can reach 150°F or more during summer. A reflective roof coating can lower that surface temperature by 50°F or more, reducing interior heat gain and stabilizing building temperatures.
Here’s how that benefits your bottom line:
- Lower Cooling Costs
By reflecting sunlight, coatings help your building stay cooler naturally. Studies show that reflective coatings can cut air conditioning costs by 15–30%, depending on roof size and insulation. - Reduced HVAC Strain
Cooler roofs mean your HVAC system doesn’t have to work as hard — reducing wear, extending lifespan, and lowering maintenance costs. - Improved Occupant Comfort
A balanced interior temperature enhances employee productivity and comfort, particularly in large industrial or office spaces. - Sustainability and Compliance
Reflective coatings support LEED® certification and local energy-efficiency standards. They also contribute to reducing urban heat island effects, improving overall city climate conditions.
The Two Leading Types of Reflective Coatings
Not all reflective coatings are created equal. The two most common types for commercial applications are elastomeric and silicone coatings. Each has distinct benefits depending on your roof type, climate, and maintenance goals.
1. Elastomeric Roof Coatings
Overview:
Elastomeric coatings are acrylic-based and flexible, expanding and contracting with your roof as temperatures fluctuate. They’re ideal for metal, TPO, and modified bitumen roofs.
Advantages:
- High reflectivity: Reduces surface heat and cooling loads.
- Cost-effective: Typically lower in price than silicone coatings.
- Easy to apply and recoat: Suitable for routine maintenance cycles.
- UV and weather resistant: Performs well under strong sunlight.
Limitations:
- Less water-resistant: Prolonged ponding water can break down the coating.
- Requires clean, dry conditions during application.
Best for:
Commercial roofs with proper drainage and minimal standing water — such as sloped metal roofs or recently installed flat systems.
2. Silicone Roof Coatings
Overview:
Silicone coatings offer superior waterproofing and are designed to handle ponding water without degrading. They adhere well to a wide variety of surfaces, including older flat roofs.
Advantages:
- Unmatched waterproofing: Ideal for flat roofs with low slopes or drainage issues.
- High UV resistance: Prevents fading and breakdown in extreme sunlight.
- Low maintenance: Requires less frequent reapplication compared to acrylic coatings.
- Longer service life: Can last up to 20 years with proper upkeep.
Limitations:
- Higher cost: More expensive upfront than elastomeric coatings.
- Surface slickness: Can attract dust and require occasional cleaning to maintain reflectivity.
Best for:
Flat commercial roofs in high-heat, high-rainfall regions like Central Texas — especially where ponding or water retention is common.
Comparing Elastomeric vs. Silicone Roof Coatings
| Feature | Elastomeric Coating | Silicone Coating |
| Reflectivity | Excellent (70–85%) | Excellent (80–90%) |
| Water Resistance | Moderate | Superior |
| Durability | 10–15 years | 15–20 years |
| Cost | Lower | Higher |
| Maintenance | Requires periodic recoating | Minimal |
| Ideal For | Sloped or well-drained roofs | Flat roofs with ponding water |
Both coating types offer outstanding energy performance — but choosing the right one depends on your roof’s slope, age, and material. Rhino Roofers evaluates these factors during a free 37-point roof inspection to recommend the most cost-effective solution.
Additional Benefits of Reflective Roof Coatings
Beyond cooling and cost savings, reflective coatings provide several long-term advantages for building owners:
- Extended Roof Life: Coatings shield the membrane from UV damage, cracking, and weathering.
- Reduced Maintenance: A seamless, watertight surface minimizes leak risks.
- Improved Appearance: Bright white coatings can make older roofs look brand new.
- Environmental Impact: Lower energy use means reduced carbon footprint and greener operations.
When combined with a preventive maintenance plan, a reflective coating can turn an aging roof into a high-performance, energy-efficient system — often without full replacement.
