Selecting a White Roof Coating

Comparing Acrylic, Hybrid, and Silicone White Roof Coatings

White roof coatings are a great way to extend the life of your roof and protect it from the elements. But with so many options available, it can be challenging to know which one to choose. Here we break down the differences between three popular types of white roof coatings for both flat and low-slope roofs.

Acrylic Coatings – Good

Acrylic coatings are water-based formulations that resist debonding, chalking, and discoloration. They also provide higher reflectivity, which helps reduce energy costs. Acrylic coatings are easy to apply and clean up, making them a great choice for DIY projects. Plus, they are generally less expensive than hybrid and silicone coatings.

Hybrid Coatings – Better

Need better weather protection? Consider a hybrid roof coating. These newer formulations combine the best of different roof coating technologies. An acrylic polyurethane hybrid coating is a cost-effective solution that provides enhanced wet weather protection, high reflectivity, and longevity versus standard acrylic coatings.

Silicone Coatings – Best

Silicone coatings are moisture-cure formulations that provide superior resistance to UV exposure, weathering, and extreme temperatures. They offer excellent adhesion and flexibility and do not get hard and brittle long term. And 100% silicone formulations deliver waterproof sealing and protection, a benefit not offered by standard acrylic coatings. Additionally, they are rain-safe in 15 minutes and have a longer lifespan than acrylic and hybrid coatings.

Good, Better, Best

So, how do you know which one to use? It’s helpful to consider options as good, better, and best.

• Acrylic roof coatings are a good option if you are more concerned about higher reflectivity for energy bill savings than wet weather protection.
• Hybrid roof coatings offer a better option for wet weather protection, durability, and high reflectivity.
• Silicone roof coatings are the best option for the longest-lasting, all-weather protection, high reflectivity, and superior waterproof sealing and protection.
