4 Useful Commercial Roof Coatings & Their Functions

When it comes to maintaining a commercial property, one of the most critical yet often overlooked components is the roof. Unlike residential roofs, commercial roofs face unique challenges due to their :

  • Larger size
  • Different materials
  • Higher foot traffic

However, with the right maintenance strategy, including the application of commercial roof coatings, property owners can extend the life of their roofs and protect their investments for years to come.

Understanding the Difference: Commercial vs. Residential Roofs

Before delving into the specifics of commercial roof coatings, it’s essential to understand what sets commercial roofs apart from their residential counterparts. Commercial roofs are typically larger and more complex in design, often incorporating materials such as built-up roofing (BUR), modified bitumen, single-ply membranes (TPO, PVC, EPDM), or metal. These materials are chosen for their durability and ability to withstand the elements over extended periods.

Additionally, commercial roofs often have additional features such as HVAC systems, skylights, and drainage systems, which require specialized maintenance to ensure their proper function. The increased foot traffic on commercial roofs, whether for routine inspections or equipment maintenance, can also lead to more wear and tear over time compared to residential roofs.

What Are Commercial Roof Coatings?

Commercial roof coatings are seamless, protective layers applied to the surface of a commercial roof to enhance its durability and weather resistance. These coatings are typically made from materials such as acrylic, silicone, polyurethane, or asphalt, each offering unique benefits depending on the specific needs of the roof.

The Benefits of Commercial Roof Coatings

  • Waterproofing: Commercial roof coatings create a seamless barrier that prevents water infiltration, protecting the underlying roof structure from leaks and water damage.
  • Extended Lifespan: By shielding the roof from UV radiation, extreme temperatures, and other environmental factors, coatings can significantly extend the life of a commercial roof.
  • Energy Efficiency: Certain types of roof coatings, such as reflective coatings, can help reduce energy costs by reflecting sunlight and reducing heat absorption, thus lowering cooling expenses.
  • Cost-Effectiveness: Compared to roof replacement, applying a commercial roof coating is a more affordable option, requiring less time, labor, and materials.
  • Minimal Disruption: Roof coating applications are typically quick and non-disruptive, allowing businesses to continue operations with minimal downtime.
  • Environmentally Friendly: Many commercial roof coatings are low-VOC (volatile organic compound) or even zero-VOC, making them environmentally friendly and safe for occupants.

Cost Considerations

The cost of a commercial roof coating can vary depending on several factors, including the size and condition of the roof, the type of coating selected, and the labor costs in your area. On average, the cost per square foot for roof coating application ranges from $2 to $6, making it a cost-effective solution compared to roof replacement, which can cost upwards of $10 to $20 per square foot.

While the initial investment may seem significant, it’s essential to consider the long-term savings and benefits that come with a properly maintained roof, including reduced energy costs, fewer repairs, and extended roof life.

4 Types of Commercial Roof Coatings

There are several types of commercial roof coatings available, each offering distinct advantages depending on the specific needs of the roof. Some of the most common types include:

1) Acrylic Roof Coatings:

Acrylic coatings are popular for their affordability, ease of application, and UV resistance. They provide excellent waterproofing properties and can be applied to a variety of roofing materials.

2) Silicone Roof Coatings:

Silicone coatings offer superior durability and weather resistance, making them ideal for roofs exposed to harsh environmental conditions. They are highly flexible and resistant to cracking, making them suitable for roofs that experience frequent expansion and contraction.

3) Polyurethane Roof Coatings:

Polyurethane coatings provide exceptional adhesion and resistance to foot traffic, making them suitable for roofs with heavy foot traffic or equipment installations. They are also highly resistant to chemicals and offer excellent waterproofing properties.

4) Asphalt Roof Coatings:

Asphalt coatings are commonly used on built-up roofing (BUR) systems and provide a durable, waterproof membrane that protects the underlying roof structure from moisture and UV damage.

Choosing the Right Commercial Roof Coating

When selecting a commercial roof coating, it’s essential to consider several factors, including:

  • Roof Material: Different roof coatings are compatible with specific roofing materials, so it’s crucial to choose a coating that is suitable for your roof type.
  • Climate and Environmental Factors: Consider the climate and environmental conditions in your area, such as temperature fluctuations, humidity levels, and exposure to sunlight, as these factors can impact the performance of the coating.
  • Performance Requirements: Determine the specific performance requirements for your roof, such as waterproofing, UV resistance, energy efficiency, and foot traffic resistance, and choose a coating that meets these needs.
  • Manufacturer Warranty: Look for roof coatings that come with a manufacturer warranty to ensure quality and reliability.

When to Consider a Commercial Roof Coating for Your Property

There are several signs that indicate it may be time to consider applying a commercial roof coating to your property:


If you notice signs of water infiltration, such as water stains or mold growth on the ceiling, it’s essential to address the issue promptly to prevent further damage.

👴🏼Aging Roof:

As commercial roofs age, they become more susceptible to damage from UV radiation, weathering, and wear and tear. Applying a roof coating can help rejuvenate an aging roof and extend its lifespan.

⚡️ Energy Efficiency Concerns:

If you’re looking to reduce energy costs and improve the energy efficiency of your property, a reflective roof coating can help reflect sunlight and reduce heat absorption, thus lowering cooling expenses.

⏰ Routine Maintenance:

Incorporating roof coatings as part of your routine maintenance strategy can help prevent costly repairs and prolong the life of your roof, saving you time and money in the long run.

Professional Commercial Roof Coating Installation
