There exist many ways to improve the energy efficiency of a home or business. You can purchase new, energy efficient appliances, for example, or spring for a thermostat upgrade. At the end of the day, however, nothing can accomplish quite so much in this regard as a roof coating. A roof plays many roles for a property. On the one hand, it defends the structure, foundation, and contents from the effects of rain, wind, hail, and sun. It also lends structural integrity, and contributes a great deal to a building’s overall energy efficiency.
A well-constructed roof accomplishes this last point through the containment of HVAC-treated air and, ideally, reflection of the sun’s UV radiation. To lend this quality to any roof, consider the application of a quality roof coating. While reflectivity stands as the primary benefit of a roof coating, these products also accomplish a great deal more. At Faile Roofing, we’re the local experts for a roof coating in Lake Wylie and Rock Hill, SC. As believers in the energy efficiency and money-saving potential of roof coatings, we recommend them for just about any commercial structure. If you remain on the fence about the value of a roof coat, simply consider all the things these products accomplish.
Roof Coating Benefits
Though many building owners pursue the application of roofing coats for their reflectivity, these products can also accomplish much more. Though there exist a number of different roof coating products, Just about any of them will:
- Improve Energy Efficiency Through the Deflection of UV Radiation
- Repair Minor Damages Such as Punctures, Tears, Scrapes, and Seam Separation
- Seal Minor Leaks and Prevent Their Recurrence
- Inhibit the Accumulation of Debris
- Avert the Need for Roof Replacement
- Extend the Life of a Compromised Roof
- Protect a Roof from Ponding and the Damaging Effects of Rainfall
Roof Coating and Repair
In addition to improved energy efficiency, a prime reason many building owners apply a roof coating is for the products’ repair capabilities. A roof will naturally absorb a great deal of damage over the years. This can occur due to hailstorms and high winds, foot traffic, the activities of pests, and more. While a roof’s durability provides it with a level of resistance to these damages, the day will come when repair needs are so widespread, the owner must consider roofing replacement.
Roof replacement, especially for a commercial structure, is an expensive and lengthy process. It’s understandable that many building owners want to avoid it for as long as possible. Thankfully, roof coatings allow you to do exactly that. As long as a roof has not degraded past a certain point, a quality roof coat will repair minor damages, seal leaks, and provide for an average of 10 years of additional service. Once those years have passed, you can even apply a second layer to enjoy the benefits all over again.
Elastomeric Roof Coating vs Silicone
A common misconception about roof coatings involves the nature of elastomeric materials. Elastomeric is an umbrella term that simply describes an elastic coating. There are many types of elastomeric roof coatings, including acrylic, polyurethane, and silicone products.
Acrylic Elastomeric Coatings: An economical, water-based product, acrylic coatings are easy to work with and apply. They are typically the standard choice on pitched metal roofs, and are slick enough to resist the accumulation of debris. You can also have an acrylic roof coat tinted to any color you like. For improved reflectivity, you can choose a white acrylic coating.
Polyurethane Elastomeric Coatings: A solvent-based coating, polyurethane products offer a great deal of tensile strength, and help prevent the damages associated with ponding. For dual-layer protection of your roof, polyurethane works well as a base coat.
Silicone Elastomeric Coatings: Another solvent-based coating, silicone works wonders as a top coat over a polyurethane base. Silicone coatings offer strong resistance to the weathering effects of sunlight, in addition to first-rate water resistance.
What Is Waterproofing a Roof?
Since roofs are naturally designed to resist damage from rainfall, you may wonder at the purpose or usefulness of a roof coating as waterproofing. Regardless of a roof’s design, water will unavoidably render some level of damage over time. As a matter of fact, water represents one of the worst threats that a roof has to face. Over the years, water will wear down a roof along its seams, especially in areas that promote ponding. Ponding describes the phenomenon of water that gathers and remains in certain areas of a flat roof. Eventually, water will make its way through a roofs seams, or into punctures caused through hail or debris, and begin to leak inside of your structure.
Roof coatings act as waterproofing in a number of different ways. First of all, they repair the minor damages and seam separation that allow water entry into a roof’s underlayment. They can also protect against ponding through the encouragement of run-off, or at the very least, offer another layer of protection in areas prone to this issue. When it comes to waterproofing a roof, silicone represents the premier choice among roof coating products. Moisture-cured itself, silicone repels water and offers a truly seamless layer of protection.
Common Questions About Roof Coatings
What Is Elastomeric Roof Coating?
Elastomeric describes a coating product with elastic properties. In other words, it can expand and contract with temperature changes, and won’t become brittle or rigid as it ages. Silicone, acrylic, and polyurethane coatings are all elastomeric products.
Can You Use Silicone on a Roof?
Absolutely! Silicone represents one of the most popular varieties of roof coatings. Silicone provides premier waterproofing and exceptional elasticity.
How Long Does Roof Sealant Last?
Though it depends on the product, a roof sealant or coating will generally last between 10 and 20 years. Some products even claim that they will last longer than this, though they are so new that comprehensive evidence to support this claim remains unavailable.
Is it Difficult to Learn How to Apply Roof Coating?
Many building owners think that roof coatings go on like paint, and require only the proper equipment for their application. In reality, an inexperienced installer will often miss important steps in the application process, which results in a shortened life and less value from the coating product. All roof coatings will also not work well with just any roof material. To achieve optimized benefits and full value from your coating investment, make sure to choose an experienced contractor.
