Crucial roof coating considerations

ICP Crucial Roof Coating
April 10, 2024 at 3:00 a.m.

By Scott DeLeo, ICP Group. 

The right roof coating can make a world of difference in a roof’s lifespan, learn about the different factors to consider. 

Roofing is a massive investment, so it’s important to make sure the decisions made before, during and after installation help give it the longest lifespan possible. Whether on a residential or commercial project, the right roof coating can be a powerful tool in prolonging a roof replacement, achieving this long roof life and ensuring protection from the elements.   

Picking the right coating can be intimidating, given that the market for coatings is already large and not slowing down in growth. There are a range of materials, from asphaltic blends to acrylic elastomeric to polyurethane and silicone available to choose from. Taking the time to consider the advantages and disadvantages of each type of coating is key to setting your client up for success. Check out this guide from the experts here at ICP Group to figure out which coating is best for your project. 

Understanding when roof coatings make sense 

When roofing contractors are deciding what coating to apply to a roof, they must consider several different factors, including: 

  • The type of roof 
  • The climate of the region 
  • The particular needs of the home or building 

Adding a coating to a roof may save the customer significant time and money by delaying or eliminating the need to do a full tear-off and replacement. Typically, roof coatings are designed to provide a durable and reflective surface regardless of what roofing material is already there and can easily be applied with a roller or spray equipment. Once the decision has been made to add a roof coating to a property, it is important to examine the different types of products available and choose the one that best fits an application’s specific requirements. 

Which coating is right for you 

Since each roofing project has its own challenges, the next question you must answer is which coating is right for the job. There are four types of roof coatings to choose from, each of which has advantages and disadvantages.  

  1. Asphaltic blends: Made with asphalt and solvents, asphaltic blends are one of the most common roof coatings in the Midwest. They are extremely durable and can handle the harsh winters and sweltering summers of the region. Over time, they can become brittle, so they may not be as effective over the long haul as some of the other choices available. 
  2. Acrylic elastomeric coatings: Also known as rubberized coatings, acrylic elastomeric coatings are well known to stretch and move with the building as temperatures change. Easy to apply and offering the most diverse options in the industry, they may oxidize over time, which could eventually compromise their performance. Additionally, they are usually water-based, which could cause problems when temperatures drop below freezing. 
  3. Polyurethane coatings: Polyurethane coatings are some of the strongest coatings on the market. They are versatile and can be applied to many different roofing surfaces, whether they’re sloped or flat, textured or smooth. Their versatility is also reflected in the fact that they can be applied at a wider range of temperatures than other options. The drawbacks to polyurethane coatings are higher costs, odors both during and after application and the toll they take on application equipment. 
  4. Silicone coatings: Silicone coatings are extraordinarily durable and can withstand a wide variety of weather conditions. Unlike many of the other options, silicone-based roofing coatings can often be applied as a single layer (one or two coats) to create ideal coverage and durability. Silicones also have the benefit of being one of the most environmentally friendly coating options. The reason silicone coatings aren’t always the top choice is that they tend to be expensive. 

Consult your supplier when making a decision 

Ultimately, you must do your own research to decide which roof coating will meet the needs of yourself and your client. Look at all the options and consider the specific needs of your particular application. Finally, working with a reputable roof coating supplier who can offer you advice on which coating will meet your needs is critical. 

As the weather in the Midwest continues to become more volatile, choosing the right roof coating is more important than ever. Understanding the choices you have will allow you to serve your clients and build your reputation as a roofing contractor.
