Roof coating is designed to reflect sunlight, reduce heat absorption, and create a barrier against the elements—for owners of a mobile home in climates like Georgia’s, they offer an affordable and effective way to cut cooling costs and more.
In this post, we’ll look at which roof coatings save the most energy, compare the best options available, and share other tips for keeping your roof in great shape.
How Roof Coatings Save Energy
Roof coatings are a simple yet effective way to make mobile homes more energy-efficient, especially in warmer climates. They work by reflecting sunlight away from the roof, which reduces the amount of heat absorbed by the home.
The process, solar reflectance, helps keep indoor temperatures lower, making it easier to maintain a comfortable environment without overworking your air conditioning system. Beyond reflecting sunlight, roof coatings also provide a layer of insulation.
Many roof coatings are designed with specific energy-saving features, such as high Solar Reflectance Index (SRI) ratings. Coatings with higher SRI values are particularly effective in hot climates like Georgia, where reducing roof surface temperatures can significantly cut cooling costs. In fact, for air-conditioned residential buildings, solar reflectance from a cool roof can reduce peak cooling demand by 11–27%.
Effective coatings can also protect the roof from UV damage and extend its lifespan, reducing the need for costly repairs.
Best Coating Options for Energy Efficiency
When it comes to saving energy with roof coatings, not all products are created equal. Choosing the right type for your mobile home depends on factors like climate, budget, and your roof’s material.
Elastomeric
Elastomeric coatings are one of the most popular choices for mobile homes, thanks to their flexibility and durability.
They form a thick, reflective layer that expands and contracts with temperature changes, preventing cracks and leaks.
- Highly reflective, reducing heat absorption on sunny days
- Effective at sealing small gaps and imperfections for added insulation
- Durable and long-lasting, even in extreme weather conditions
Silicone
Silicone coatings are ideal for homes in humid or rainy climates, as they offer excellent water resistance along with energy-saving benefits.
- Exceptional UV reflectivity helps keep roofs cooler
- Naturally waterproof, preventing moisture-related issues like mold or rot
- Low-maintenance and resistant to weathering over time
Acrylic
Acrylic coatings are a budget-friendly option that still offers strong performance in terms of energy efficiency.
They are water-based and easy to apply, making them a popular choice for mobile homeowners.
- High Solar Reflectance Index (SRI) for reducing cooling costs
- Works well in moderate climates with consistent sunlight
- Eco-friendly and available in a range of reflective finishes
Which One is Right for You?
The best coating depends on your specific needs:
- For hot, dry climates: Elastomeric or acrylic coatings perform well by reflecting sunlight and reducing roof temperatures.
- For rainy or humid regions: Silicone coatings provide superior moisture resistance and reflectivity.
- For budget-conscious homeowners: Acrylic coatings offer solid energy-saving benefits at a lower price point.
Selecting a product with high reflectivity and durability ensures you get the best results for your home and climate.
Other Maintenance for Manufactured Homes
Maintaining a manufactured home involves more than just roof coatings—it’s about taking care of every part of the structure to ensure long-term comfort and efficiency.
Here are some key maintenance tasks to keep your home in excellent condition:
- Inspect the foundation regularly: Look for signs of settling, cracks, or moisture damage.
- Check for water leaks: Examine plumbing fixtures, under-sink areas, and your home’s skirting for leaks that could lead to structural damage or mold.
- Maintain proper ventilation: Clean vents, ducts, and fans to keep airflow consistent and prevent moisture buildup, which is especially important in humid climates.
- Seal windows and doors: Inspect weather stripping and caulking to prevent drafts and energy loss. Proper sealing also helps keep pests out.
- Schedule routine roof inspections: Even with a roof coating, regular inspections ensure your roof remains in good condition and identify minor issues before they escalate.
When to Call a Professional
While many aspects of maintaining and coating a mobile home roof can be handled by homeowners, there are times when professional expertise is invaluable. A trained professional can:
- Assess the condition of your roof to determine whether repairs are needed before applying a coating.
- Recommend the most effective roof coating for your climate, roof material, and energy-saving goals.
- Ensure the coating is applied evenly and correctly, preventing issues like peeling or poor adhesion.
- Identify underlying issues, such as leaks or structural weaknesses, that might not be immediately visible.
Conclusion
A high-quality roof coating reflects sunlight, reduces heat absorption, and helps lower cooling costs—especially for a home or mobile home in warm climates like Georgia. Combined with regular maintenance, these coatings not only improve energy savings but also protect your home from wear and tear over time.
