Key Takeaways

• Roof coatings add up to 25 extra years to your roof’s life. [10]
  
• Reflective coatings cut cooling costs by up to 40–50 °F. [4]
  
• They seal minor cracks and seams, helping prevent leaks. [3]
  
• Coatings are affordable, eco-friendly, and low-maintenance. [2]
  
• Picking the right type and installer ensures long-term performance.

Why Roof Coatings Matter

Flat and aging roofs often develop small cracks, exposed seams, and UV damage over time. A roof coating creates a seamless, elastic layer that guards against leaks, sun exposure, and water damage extending the roof’s life without costly tear-offs.[10]

• Energy Savings: Light-colored coatings especially silicone reflect sunlight, helping reduce cooling loads and utility costs. [1][4]
• Leak Prevention: Elastomeric coatings fill cracks and seal seams, creating a waterproof skin that keeps water out.[3]
• Cost Efficiency: A coating costs significantly less than a full replacement. It’s an economical strategy when your roof is still in decent condition. [6]
• Eco-Friendly Choice: Coatings minimize waste and lower energy use supporting a greener roof lifecycle. [1]

Types of Roof Coatings & When to Use Them

• Acrylic Roof Coatings - These water-based coatings are known for their excellent UV resistance and reflectivity. They’re a cost-effective solution for sloped metal roofs and climates with lots of sunshine. Acrylic coatings help reduce cooling costs and extend roof lifespan.

• Silicone Roof Coatings - Best suited for flat roofs or areas with heavy rainfall and ponding water. Silicone coatings offer outstanding waterproofing and weather resistance. They are often used in commercial roofing due to their long-lasting durability.

• Polyurethane Roof Coatings - Known for their impact and abrasion resistance, polyurethane coatings are ideal for roofs with heavy foot traffic, such as warehouses or industrial buildings. They offer strong adhesion and hold up well under mechanical stress.

• Asphalt-Based Roof Coatings - Traditionally used on built-up roofing systems, these coatings provide a strong waterproof barrier. They are more common on older or existing asphalt-based roofs and help reinforce the current system against leaks.

• Hybrid Roof Coatings - Some modern products combine the strengths of different materials like acrylic and silicone to create customized solutions. These are chosen based on unique building needs, climate, and roof use.
