If your existing roof has a few imperfections, consider a commercial roof coating system. They provide long-lasting protection and cost savings, making it a win-win for any commercial property owner. Read on to find out which coating is most suitable for you.
What Is a Commercial Roof Coating System?
When commercial property owners face roofing problems, they may initially consider two options: repairs or replacement. However, their existing structure may benefit from restoration using a commercial roof coating system instead. These are made of synthetics and polymers, and once applied to the existing roof, they create an adhesive, seamless surface that fills cracks, holes, and other minor imperfections.
What Are the Benefits of Commercial Roof Coatings?
A roof coating is the perfect alternative to costly, recurring repairs or an expensive, time-consuming replacement. In addition to restoring the existing roof structure, a commercial roof coating system shields the membrane from harmful UV rays, excessive rain, and hail, extending the life of your roof by 10 to 15 years.
Suppose your flat roof has major issues, such as large holes or openings in various areas, several leaks, and an overly saturated underlayment. In that case, it’s safer and wiser to get a roof replacement. However, if your existing structure has a few minor issues, like surface-level cracks or scratches, it likely qualifies for a commercial roof coating system, which is:
Easy to Apply
Roof coatings aren’t ideal for DIY projects or inexperienced roofers, but the application process is quick and straightforward for seasoned professionals. Many roof coatings are also known as fluid-applied roof coatings because they’re made of a liquid substance that is then sprayed onto the surface using specialized equipment.
Fluid-applied coatings dry as a hard topcoat that keeps out water, pests, and debris. Plus, there’s no drilling, welding, or nailing required. For these reasons, the application process requires less time and labor compared to other commercial roof systems.
Environmentally Friendly
Do you know how much roofing material contributes to the landfill every year? According to the Missouri Department of Natural Resources, the state alone adds 146,500 tons of roofing waste annually. Commercial roof coating systems eliminate the need for roof tear-offs. As mentioned before, coatings are sprayed directly onto roofs, making them very effective for most flat roofing structures. Even if your current system is in good shape and you just want to add more protection, roof coatings are compatible with the most common roofing materials, including:
Cost Effective
Roof tear-offs are an additional cost for roof replacement projects. But with a commercial roof coating system, there’s no tear-off necessary, so you don’t have to worry about that added cost. Materials needed for a fluid-applied roofing system are less expensive, as well.
UV Resistant
Commercial roof coating systems also reflect more sunlight than they absorb. The roof’s surface stays much cooler in the summer despite the sun constantly beating down on the building. When the roof is cooler, indoor temperatures are more comfortable and stable. As a result, business owners can expect lower utility bills since the thermostat stays at a reasonable setting every day instead of being cranked to the max.
What Are the Different Kinds of Roof Coatings?
Another advantage to roof coatings is their versatility. They come in a variety of materials and different colors. Each commercial roof coating system has different characteristics and benefits, as well. If you’re wondering what is the best flat roof coating for your structure, here are some popular options:
Acrylic
An acrylic roof coating is a water-based solution that works well with most single-ply roof systems (TPO and EPDM) and metal. Acrylic is a fluid-applied, rubber-like membrane. Acrylic looks like house paint and has the same consistency. However, it’s applied between 15 to 30 mils thick, which is 5 to 10 times thicker than house paint.
Acrylic coatings are typically white, which boosts their UV protection. These commercial roof coating systems offer incredible reflectivity and can reduce the roof’s temperature by at least 20 degrees Fahrenheit when sitting in direct sunlight, so it’s perfect for hot and humid regions. Additionally, acrylic roof coatings are radiation and hail-resistant, thanks to their excellent flexibility.
Silicone
100% silicone roof coatings are the perfect option for extreme moisture resistance. Since they’re incredibly adhesive, they provide the ultimate insulation. Silicone commercial roof coatings are also less prone to leaks, even when they’re covered in areas of ponding water. Therefore, property owners in rainy regions benefit from silicone roof coatings the most.
Silicone also contributes to your building’s energy efficiency since it’s available in many light, reflective colors. However, it does require regularly scheduled, light power washing to work correctly and offer a long service life. Otherwise, it can lose some reflectivity because of dirt and debris buildup.
Polyurethane
Polyurethane commercial roof coating systems were originally made for application over foam roofs. Professionals have found that polyurethane works well with many single-ply or flat roofing structures. Polyurethane roof coatings provide excellent impact resistance and withstand foot traffic quite well.
Since polyurethane coatings have the lowest UV resistance, they’re ideal for regions with minimal UV exposure. Additionally, aliphatic topcoats are great add-ons to boost polyurethane’s reflectivity and hold its color longer.
