As a commercial property owner in Papillion, NE, you understand how crucial your roof is in protecting your business. Metal roofing systems are known for their strength and longevity, but they still require regular maintenance to remain watertight and energy-efficient. One of the most effective ways to extend the life of a metal roof is by applying a metal roof coating.
But how should you apply it? Commercial property owners often wonder whether to choose spray or roll-on application. Each method has its own advantages and drawbacks that can impact performance, cost, and long-term durability.

Why Metal Roof Coatings Matter
Before diving into application methods, it’s worth reviewing why coatings are essential for metal roofing systems.
Metal roofs are vulnerable to expansion and contraction cycles, UV degradation, rust, and seam failure over time. A professional-grade roof coating addresses these issues by:
- Sealing seams and fasteners: Preventing water infiltration at vulnerable joints.
- Creating a reflective barrier: Reducing rooftop heat load and energy costs.
- Protecting against corrosion: Encapsulating existing rust and preventing new oxidation.
- Extending service life: Adding years—or even decades—to a metal roof’s usable lifespan.
Whether you own a warehouse, factory, retail plaza, or office in Papillion, NE, applying a metal roof coating is a proven way to avoid disruptive, costly full replacements.
Spray Application: Pros and Cons
Spray application uses specialized equipment to atomize and apply the coating evenly across the metal surface.
Advantages:
- Speed: Spraying large commercial roofs can be significantly faster than rolling, especially for expansive, unobstructed areas.
- Uniform Coverage: A skilled applicator can achieve a smooth, seamless membrane with consistent thickness, even over corrugations or irregular profiles.
- Access to Tight Areas: Spray can reach angles, seams, and fasteners that are difficult with rollers.
Considerations:
- Overspray Risk: Nearby equipment, vehicles, and walls may need protection to avoid accidental coating.
- Weather Dependency: Wind and humidity can complicate spraying. Calm, dry days are best for optimal results.
- Equipment Costs: Spraying requires investment in and maintenance of specialized equipment.
Spray application is popular on very large or complex roofs where uniform coverage and speed deliver major benefits.
Roll-On Application: Pros and Cons
Roll-on application involves using rollers, brushes, or squeegees to spread the coating manually across the roof surface.
Advantages:
- Precision: Rollers let applicators precisely control where coating is placed, reducing waste and overspray.
- Better for Small or Obstructed Roofs: Ideal for roofs with HVAC units, skylights, or complex parapets.
- Cost-Effective for Small Jobs: No need to invest in or rent spraying equipment for limited square footage.
- Weather Flexibility: Roll-on can often proceed when conditions would complicate spraying.
Considerations:
- Labor Intensive: Rolling is slower, especially on large, open roofs.
- Potential for Uneven Thickness: Maintaining consistent mil thickness across wide areas takes skill and attention.
- Surface Preparation Critical: As with spray, thorough cleaning and priming are vital for adhesion and durability.
Roll-on application is often chosen for smaller commercial roofs, roofs with many penetrations, or projects needing precision.
Choosing the Best Method
Ultimately, there is no one-size-fits-all “best” method, only the one that suits your building and project goals.
Key factors to consider include:
- Roof Size: Large, open roofs typically benefit from spray application due to its efficiency.
- Roof Complexity: Roofs with numerous penetrations or tight spaces may be better suited for roll-on application.
- Weather Conditions: Papillion’s variable weather requires careful planning to ensure optimal cure times and proper application conditions.
- Budget: Labor and equipment requirements can influence the overall project cost.
- Desired Warranty: Some manufacturers specify certain methods to maintain warranty compliance.
