No matter the quality of your roof, all roofing materials will begin to degrade over time due to constant exposure to the elements. If your roof has begun to show its age through small cracks, shingle blisters or reduced energy efficiency, your first assumption may be that it is time for a roof replacement. But for a roof which is still in good condition, there is another option. That is, elastomeric roof coatings, which consist of a durable film typically made out of resins or polymers. 

While applying a roof coating is a relatively simple process, it is one which should be completed by a professional for the best results. And for property owners in Southeast Louisiana, that professional is one phone call away. At WestBank Roofing, we can not only help you determine whether roof coatings are a good choice for your building, but also what type would best serve your needs. 

What are Elastomeric Roof Coatings?

Elastomeric roof coating is a thick, waterproof fluid composed of resins and/or polymers, materials which give the coating its durability and elasticity. Similar to paint, though much thicker due to its composition being higher in solids than liquids, the coating is typically rolled, brushed or sprayed onto roofs during the application process. Once cured, the material forms a solid, seamless, waterproof and somewhat rubbery coating on the surface of your roof that can last for around 10 to 20 years. Elastomeric coatings can be used on a variety of roofing materials—including metal roofs, single-ply membranes and concrete—and styles. That is, while popular for use on flat roofs due to the potential for pooling water, it can be used on pitched roofs as well. 

Common Types of Elastomeric Roof Coatings

While roof coatings may come in a variety of forms, some of the most common types of elastomeric roof coatings are:

1. Acrylic

Acrylic is a durable, water-based and cost-effective coating ideal for providing protection from UV rays due to its high reflectivity. It also contains rust inhibitors, which makes it a beneficial option for metal roofing. However, its water-based nature makes it susceptible to a loss in functionality due to ponding water or applications done in cold temperatures. 

2. Silicone

Silicone roof coatings are high in solids, which makes them exceptional at sticking to roofing materials once placed. As a resin-based material, they are also highly resistant to long-term water exposure, which makes them ideal for flat roofs. And, like acrylic, silicone has high reflectivity and UV resistance. However, these coatings may attract dirt relatively easily, which can negatively impact their ability to reflect sunlight over time. Additionally, they may become slippery when wet, making it necessary to practice caution when walking on a silicone-coated roof. 

3. Polyurethane

Ideal for roofing that sees a lot of foot traffic, polyurethane coatings are durable, adaptive and impact-resistant. They can also withstand both chemical exposure and long-term water exposure, making them a popular choice for commercial roofs. However, the benefits of this roof coating come with some downsides, including a price tag which is higher than many other types of roof coatings. Additionally, they typically come in two forms—aromatic and aliphatic, only the latter of which is UV resistant.

4. Butyl

Also known as butyl rubber, butyl roof coatings are ideal for a variety of roofing materials, including metal, modified bitumen and concrete. Once cured, it forms a flexible, seamless membrane low in permeability. That is, the ability of liquids or gases to pass through a material. Additionally, like many other kinds of roof coatings, it can be both reflective and resistant to damage from ponding water.

Benefits of Applying a Roof Coating to Your Property

Besides reflecting sunlight, resisting weather damage and extending the lifespan of your roof, what exactly can roof coatings do for your property? The answer, depending on the type of coating you choose, is quite a lot. Some potential benefits of applying elastomeric roof coatings include:

1. Increased energy efficiency. By filling seams and small cracks, as well as improving your roof’s ability to cast back sunlight, elastomeric coatings can improve your property’s energy efficiency. That is, reducing the amount of energy consumed during the completion of tasks such as cooling your home via air conditioner. The more energy efficient your property is, the less your heating and cooling systems have to fight against outdoor temperatures, and the lower your utility bill will be.
2. Cost savings. By forming a protective layer over your roof, elastomeric coatings can help to prevent future roof damage. This can, in turn, help you avoid repair costs and allow you to wait longer before getting a roof replacement. Additionally, by preventing water intrusion, roof coatings keep your internal space safe from potentially damaging leaks. 
3. Aesthetics. Roof coatings are often available in a variety of colors, allowing you to personalize your property and boost the aesthetic appeal of your building.
4. Environmentally friendly. By extending the lifespan of your roof, fewer roofing materials are sent to the landfill, lessening the amount of waste added to these sites each year. Additionally, many roof coatings are made with eco-friendly materials.
5. Sound dampening. The rubbery texture of elastomeric coatings can help dampen sound waves. Unlike metal roofs, this can reduce rather than amplify noises such as wind, rain and hail. 

What to Consider When Choosing an Elastomeric Roof Coating

When it comes to choosing the right elastomeric roof coating for your property, there is plenty to consider, including:

1. Compatibility with roofing materials and styles. Is your roof flat or pitched? What material does it use—metal panels, concrete, modified bitumen or something else entirely? Speak to your contractor to make sure the type of coating you choose is capable of properly adhering to—and functioning on top of—your roof.
2. Reflectivity and UV resistance. This will help to determine factors including the coating’s effect on your property’s energy efficiency.
3. Climate. Choose an elastomeric roof coating which is ideal for your area’s weather patterns. For example, an acrylic coating would not be the best choice for a property in a humid or rain-prone area.
4. Cost. Some coatings—such as polyurethane—are more expensive than others. Talk to your contractor to determine which roof coating options can meet both your budgetary constraints as well as your property’s needs.
5. Roof condition. If your roof has small issues such as cracks or blistered shingles, a roof coating may be the perfect way to extend its lifespan. But if your roof has sustained severe damage or is actively deteriorating, you should consider a roof replacement instead.
