Silicone Vs Acrylic Roof Coating: Which One To Choose?

Silicone Vs Acrylic Roof Coating

When it comes to protecting your roof, choosing the right coating can make all the difference. Two popular options for roofing coatings are silicone and acrylic. Both offer their own unique benefits and deciding between the two can be a difficult task.

Silicone roof coatings are made from a synthetic material known as silicone polymer. This type of coating is transparent and has a rubber-like consistency, making it flexible and durable. Acrylic coatings, on the other hand, are water-based and made from an acrylic resin. They dry to form a hard protective layer over the roof.

Let’s explore a bit in detail silicone vs acrylic roof coating differences and learn which coating will work best for commercial and residential homes.  

What Is Silicon Roof Coating?  

What is Silicon Roof Coating

Silicone roof coatings have been gaining popularity in recent years due to their many advantages. A silicone roof coating is a long-lasting roofing solution composed of a liquid silicone compound that is put to the surface of existing flat and low-slope roofs such as metal, single-ply membranes, and modified bitumen.

They are highly resistant to UV rays and extreme weather conditions, making them a great choice for roofs that are constantly exposed to sunlight and harsh elements. The flexibility of silicone also allows it to expand and contract with temperature changes, preventing cracks and leaks on the roof.

 What Is Acrylic Roof Coating?

Acrylic roof coatings are another popular option for protecting roofs. They are water-based, making them environmentally friendly and easy to clean up. Acrylic coatings are also highly reflective, which helps to reduce the amount of heat absorbed by the roof. This can result in lower energy costs for the building.

Silicon Vs Acrylic Roof Coating: Pros And Cons 

Silicon Vs Acrylic Roof Coating: Pros and Cons 

Acrylic Roof Coatings Pros And Cons

Pros:

  • Acrylic roof coatings can be used on various types of roofs, including metal, asphalt, and single-ply membranes.
  • Compared to other types of roof coatings, acrylic is generally more affordable
  • Environmentally friendly 
  • Easy to clean up 
  • Highly reflective, reducing energy costs.

Cons: 

  • Over time, acrylic roof coatings can become chalky due to exposure to the elements and harsh weather conditions. 
  • Not as durable as silicone coatings
  • Can be prone to cracking and peeling over time 

Silicone Roof Pros And Cons 

Pros: 

  • Silicone has excellent durability and can withstand harsh weather conditions like extreme heat and UV rays. 
  • It also has good resistance to ponding water, making it suitable for flat roofs.
  • Similar to acrylic, silicone is flexible and can expand and contract with changes in temperature without compromising its integrity. 
  • It can be applied quickly and easily by spraying or rolling, reducing labor costs and installation time.

Cons

  • The initial cost of a silicone roof coating may be higher compared to other roofing options. 

  • Applying silicone roof coatings requires specialized equipment and training, making it more challenging for DIY projects.

Acrylic Roof Vs Silicon Roof: Cost Comparison 

How Much Does Silicone Roof Coating Cost? 

The cost of a silicone roof coating can vary depending on several factors such as the size and condition of your roof, labor costs, and location. On average, the cost for a silicone roof coating ranges from $2 to $5 per square foot.

How Much Does Acrylic Roof Coating Cost? 

It is a more affordable alternative to silicone coating, with an average cost ranging from $0.50 to $2 per square foot.

There are different types of acrylic coatings available, each with varying prices. For example, water-based acrylic coatings tend to be less expensive than solvent-based ones. 

Silicon Vs Acrylic Roof Coating: Lifespan Comparison 

Acrylic Roof Vs Silicon Roof: Cost Comparison 

While acrylic coating may be more budget-friendly, it typically has a shorter lifespan compared to silicone coating. Acrylic coatings usually last between 5-10 years, whereas silicone coatings can last up to 20 years.

The professional roof installation also determined the lifespan. It is best to get professional help whenever you plan to install your residential or commercial roof. 

Which Roof Coating Offers More Reflectivity Than The Other: Silicon Or Acrylic?

Silicone coating is known for its high reflectivity, with a solar reflectivity of 85-90%. On the other hand, acrylic coating typically has a lower reflectivity of around 70%. This means that silicone coating can help keep your building cooler and reduce energy costs more effectively.

UV reflectiveness is significant because when sunlight strikes a polymer, it absorbs a portion of the energy. This radiation causes the polymer to vibrate and shatter into smaller bits. Finally, this damages materials over time through a process known as UV degradation. Acrylic polymers are transparent to UV light, which means they do not absorb the sun’s rays but instead reflect it away from the roof material and back into the atmosphere. 

Silicon Vs Acrylic Roof Coating: Which One Offers Better Resistance To Ponding?

Silicon Vs Acrylic Roof Coating: which one offers better resistance to ponding

Silicone coating is the winner in this category as well. Due to its flexibility and ability to adhere to various surfaces, it can withstand ponding water without deteriorating. 

Acrylic coating, on the other hand, may start to break down and develop cracks under constant exposure to standing water.

Its rubber-like properties make it highly resistant to weathering and UV rays, ensuring a longer lifespan for your roof. Acrylic coatings may be prone to cracking and chipping over time, especially in harsh weather conditions.

Conclusion 

the choice between silicon and acrylic roof coatings can be a crucial decision for both residential and commercial property owners. While silicon offers exceptional durability and weather resistance, acrylic coatings provide versatility and ease of application. Understanding the specific needs of your roof and climate conditions is essential in making an informed decision that ensures long-term protection and cost-efficiency.
