Selecting Metal Roof Coatings for Your Restoration

In this article, we will explore different types of coatings used in metal roof restoration, such as acrylic and elastomeric coatings. We will discuss their pros and cons, application methods, and how to select the best one for specific roofing needs.

Metal Roof Coatings: Why They Are Important

Coatings are protective layers applied to the surface of a metal roof to boost its durability, energy efficiency, and appearance. These coatings can protect against rust, UV radiation, and water infiltration while providing a reflective surface to reduce heat absorption.

The Different Metal Roof Coating Systems

Before applying coatings to your building’s roof, you need to know the different types that could best benefit your system.

Acrylic Coatings

Pros:

Affordability: Acrylic coatings are generally more cost-effective compared to other types.
UV Resistance: They offer excellent protection against UV rays, helping to reduce roof temperatures and energy costs.
Flexibility: Acrylic coatings remain flexible in varying temperatures, preventing cracking and peeling.
Ease of Application: These coatings are easy to apply with a brush, roller, or spray.

Cons

Water Sensitivity: Acrylic coatings can be less effective in areas with heavy rainfall, as they are water-based and may degrade faster when exposed to standing water.
Durability: They may not be as durable as elastomeric coatings, requiring more frequent reapplication.

Application Methods: Acrylic coatings can be applied using brushes, rollers, or spray equipment. Multiple thin layers are crucial for even coverage and better performance.

Elastomeric Coatings

Pros:

Flexibility: Elastomeric coatings are highly flexible, allowing them to expand and contract with the roof’s movements, preventing cracks and leaks.
Durability: They provide excellent durability and can withstand harsh weather conditions.
Energy Efficiency: Elastomeric coatings are highly reflective, reducing roof temperatures and lowering energy costs.

Cons:

Application Temperature: These coatings require specific temperature conditions for proper application, which can limit their use in certain climates.
Cost: Elastomeric coatings can be more expensive than acrylic coatings but offer better performance and longevity.

Application Methods: Elastomeric coatings are applied using brushes, rollers, or spray equipment. Proper surface preparation and application in favorable weather conditions are crucial for optimal results.

Spray-On Roof Coatings for Metal Roofs

Pros:

Easy Application: Spray-on coatings create a uniform layer for the roof’s surface, reducing the risk of leaks.
Quick Application: The spray-on method allows for faster application than traditional methods.
Versatility: Spray-on coatings can be used on various roof types and complex geometries.

Cons:

Specialized Equipment: Spray-on coatings require specialized equipment and expertise for proper application.
Cost: The initial cost of spray-on coatings and equipment can be higher compared to other methods.

Application Methods: Spray-on coatings are applied using specialized spray equipment. Following the manufacturer’s guidelines for proper application and safety is essential.

5 Considerations for Selecting the Right Roof Coating for Your Needs

Choosing the right metal roof coating involves considering several factors to provide the best performance and longevity for your building. Let’s run through a few aspects you should discuss with your team:

Climate and Weather Conditions: Consider the local climate and weather conditions when selecting a roof coating. Elastomeric coatings offer excellent UV resistance for sunny regions.
Roof Condition: Assess the current condition of your metal roof. Elastomeric coatings provide superior waterproofing and durability for roofs with existing leaks or damage.
Budget: Evaluate your budget and cost considerations. Acrylic coatings are more affordable, while elastomeric coatings offer better long-term performance and durability.
Application Method: Consider the ease of application and availability of specialized equipment. Spray-on coatings provide a great finish but require professional application.
Energy Efficiency: If energy efficiency is a priority, choose a coating with high reflectivity, such as elastomeric or acrylic coatings, to reduce roof temperatures and lower energy costs.
