At Springfield, we frequently receive inquiries about the quality and durability of commercial roof coatings. While our primary expertise lies in singly-ply membrane installation, we can acknowledge that there is a time and place for roof coatings after careful consideration.   

Types of Roof Coatings 

There are various coating options available. The most commons ones we’ve come across include:  

  • Polyurethane 
  • Elastomeric 
  • Aluminum 
  • Acrylic  
  • Multi-ply asphalt 

One of the main reasons for choosing a roof coating is that it is often less expensive than roof replacement. However, if not carefully considered, you may not get the desired results.  

Advantages of Commercial Roof Coatings 

Not all roof coatings are created equally. In fact, we have successfully utilized coatings in specific service situations depending on the customer’s roof type. Based on our experience, elastomeric and aluminum coatings have proven effective in extending the lifespan and enhancing the protection of commercial roofs.  

We’ve found coatings can be a viable solution for servicing older built-up roofs (BUR). They can help protect the roof from the sun and act as a stabilizer. Additionally, it’ll help with waterproofing, but it won’t be and shouldn’t be considered a viable long-term solution. 

Challenges of Using Roof Coatings on Commercial Buildings 

Suitability for Northern Michigan’s Climate 

Northern Michigan experiences extreme weather conditions, from harsh winters to warm summers. Many coating solutions are designed with specific weather conditions in mind, making it essential to choose the right product for your area. The intense cold can cause some coatings to become brittle and crack, while the heat can lead to expansion issues. Furthermore, the frequent freeze-thaw cycles can exacerbate any existing weaknesses in the roof, potentially reducing a coating’s lifespan and effectiveness.  

Read the Fine Print 

While roof coating material technologies have advanced significantly since they were first released into the commercial market, it is crucial to read the fine print when considering a coating. Although coatings may come with guarantees or warranties, these are often contingent upon a meticulous installation process, which includes pressure washing, drying, and repeated applications. This can lead to significant labor costs, bringing you close to the expense of a complete re-roofing project.  

Consider the Existing Roof 

The type and condition of your existing roof will significantly impact the performance of the coating. If the roof has underlying issues like leaks or cracks, these must be repaired before applying a coating.  A coating is only as effective as the surface it is applied to. Single-ply membranes or metals roofs do not offer the appropriate level of adhesion needed for coatings, limiting the ability to patch or repair in emergencies. Additionally, dirty or oily surfaces can prevent proper bonding, reducing the coating’s effectiveness and lifespan. 

Searching for a Needle in a Haystack 

One a coating ages and begins to crack, it can be challenging (or nearly impossible) to pinpoint the root cause of any subsequent roof problems. Once applied, the coating forms a layer that can hide cracks or holes, complicating repairs. As the building expands and contracts, new issues may develop that are difficult to detect through a coating.  

Interruptions to Business Operations 

Certain roof coatings can emit strong odors during application, potentially requiring a temporary halt in business operations. These smells can be intolerable for employees and customers, leading to costly disruptions.  

The Final Verdict on Roof Coatings 

Roof coatings should be considered a temporary solution rather than a long-term, standalone waterproofing protection. While they are often less expensive than a complete re-roof project, improper storage, preparation, or installation can lead to significant future issues for your business.  

For businesses looking for a reliable and long-lasting solution, it is essential to weigh the pros and cons of roof coatings carefully. At Springfield, we are here to provide expert guidance and help you make the best decision for your commercial roofing needs. Let’s chat – call (231) 263-5300 now.
