Choosing the right roof coating depends on various factors, including the specific needs of your roof, the climate, and your budget. Each type offers unique benefits and drawbacks, so it’s crucial to consider these aspects before making a decision.

Benefits of Roof Coatings

Energy Efficiency

One of the standout benefits of roof coatings is their impact on energy efficiency. Many roof coatings, such as acrylic and silicone, have high reflectivity, which means they can reflect a significant portion of the sun’s rays. This reduces the amount of heat absorbed by your roof, keeping your building cooler. Studies show that properly formulated acrylic coatings can reduce surface temperatures by as much as 20 degrees Fahrenheit. This can lead to lower cooling costs, especially during hot summer months.

UV Protection

Roof coatings provide excellent protection against ultraviolet (UV) radiation. UV rays can cause significant damage to roofing materials over time, leading to cracks, degradation, and a shorter lifespan. Acrylic and silicone coatings are particularly effective in providing this protection. By shielding your roof from harmful UV rays, these coatings help maintain the integrity and appearance of your roof for a longer period.


Water damage is a common issue for many roofs, especially in areas prone to heavy rainfall or snow. Silicone coatings shine in this regard, as they are highly resistant to ponding water. Unlike other coatings, silicone doesn’t become hard or brittle, ensuring long-term waterproofing. This makes it an excellent choice for flat or low-slope roofs where water tends to accumulate. Waterproofing your roof with a high-quality coating can prevent leaks, mold growth, and structural damage.


Durability is a key benefit of using roof coatings. Polyurethane coatings, for example, offer high durability and impact resistance, making them suitable for high-traffic areas and roofs exposed to harsh conditions. These coatings can withstand physical impacts, chemical exposure, and environmental stressors, ensuring your roof remains in good condition for many years.

By extending the lifespan of your roof, reducing maintenance needs, and protecting against various forms of damage, roof coatings offer a cost-effective solution for maintaining your roof’s health and performance.

Applying Roof Coatings


Proper preparation is essential for a successful roof coating application. Start by thoroughly cleaning the roof surface. Use a pressure washer to remove dirt, debris, and any existing loose coatings. Pay special attention to areas with mold, mildew, or oil stains, as these can affect adhesion.

Inspect the roof for damage. Repair any cracks, holes, or seams before applying the coating. This ensures a smooth, even application and maximizes the coating’s effectiveness. Follow the manufacturer’s guidelines for any additional preparatory steps, such as priming the surface.

Application Methods

There are several methods to apply roof coatings. The most common are:

  • Brush and Roller: Ideal for small areas or touch-ups. Use a brush for edges and a roller for larger, flat surfaces.
  • Airless Spray: Best for large roofs. This method ensures even coverage and is faster than manual application. High-pressure airless spray equipment is recommended for a uniform finish.

Always apply the coating in multiple thin layers rather than one thick layer. This helps with even drying and reduces the risk of cracking.

Curing Time

Curing time varies based on the type of coating and weather conditions. Acrylic coatings need warm weather and low humidity for optimal curing, often taking several days. Silicone coatings cure faster and can handle moisture better, making them suitable for variable weather.

Pay attention to the manufacturer’s curing time instructions. Avoid applying coatings in freezing temperatures or right before rain, as this can impede the curing process. Some modern acrylic coatings offer instant-set options, reducing the risk of weather-related issues.


Regular maintenance extends the life of your roof coating. Inspect your roof periodically for signs of wear, such as thinning or peeling. Clean the surface to remove dirt and debris, which can accumulate and affect reflectivity.

Recoating is typically needed every 10-20 years, depending on the type of coating and environmental conditions. For example, Armor Garage guarantees their coatings for 12 years, with a lifespan of 15-20 years with routine maintenance. Recoating is a simple process that involves cleaning the roof and applying a new layer of coating, further extending the roof’s lifespan.

By following these steps, you can ensure a successful roof coating application that protects and enhances your roof for years to come.

Next, we’ll discuss how to choose the right roof coating for your specific needs.

Choosing the Right Roof Coating

Choosing the right roof coating can be a game-changer for the longevity and efficiency of your roof. Here’s what you need to consider:

Weather Resistance

Weather resistance is crucial, especially in places with extreme weather conditions. For instance, if your area experiences heavy rain or snow, you need a coating that can withstand ponding water. Silicone coatings are excellent for these conditions as they resist water and remain durable over time.

In hot climates, acrylic coatings shine due to their UV resistance and ability to reduce surface temperatures by up to 20 degrees F. This can be especially beneficial in places like Texas, where the sun is intense.

Roof Type Compatibility

Not all coatings are suitable for every roof type. Acrylic coatings are versatile and can be used on single-ply membranes and metal systems. However, they are not recommended for roofs with standing water.

Silicone coatings, on the other hand, are great for flat or low-slope roofs where water pooling is common. They adhere well to various surfaces, including rubber and concrete.

Polyurethane coatings are ideal for roofs that need protection from physical impacts or chemical exposure, making them suitable for industrial settings.


Reflectivity is about how well a coating can reflect sunlight, reducing the heat absorbed by your roof. Acrylic and silicone coatings are known for their high reflectivity. This feature not only keeps your building cooler but also reduces energy costs.

For example, studies have shown that acrylic coatings can lower rooftop temperatures significantly, which can lead to reduced air conditioning bills. Gardner’s 100% Silicone Flat Roof Coat-N-Seal offers high reflectivity and durability, making it a great choice for those looking to enhance energy efficiency.


While initial costs are important, think long-term. Acrylic coatings are generally more economical upfront but may require more frequent recoating. Silicone coatings might be pricier but offer longer-lasting protection, especially in wet environments.

Consider the Armor Garage example: they offer a coating that lasts 15-20 years with routine maintenance. Although the initial investment might be higher, the long-term savings in maintenance and energy costs make it a cost-effective option.
