Often referred to as the “original” elastomeric coatings, acrylic roof coatings are generally a popular choice for commercial flat roofs. They are also a serviceable solution for a variety of conventional flat roof substrates including modified bitumen, single-ply, EPDM, built-up roofs, and spray polyurethane foam.
Acrylic coating systems are a great solution to restore and protect commercial roofs. Even though silicone roof coatings have taken their spot as the go-to commercial roof coating system. There are some instances where a silicone roof coating may not be the best solution and vice versa. You can get a full comparison of the two roof coating systems here. There is a reason this type of commercial roofing system has lasted for so long, but it does have its setbacks. So let’s take a look at 3 PROS AND 3 CONS YOU NEED TO KNOW ABOUT ACRYLIC ROOF COATINGS.
1. Acrylic Roof Coatings Are Cost-Effective (Pro)
Compared to other chemistry types, acrylic roof coatings are less expensive and just as durable. This means building owners can expect an acrylic roofing system to deliver long-lasting performance, reduced energy consumption, and decrease maintenance costs.
This powerful combination of cost and performance is what makes acrylic coatings such a popular and sensible roof restoration solution.
2. U.V Protection (Pro)
Acrylic roof coatings are highly reflective and UV resistant. These important qualities can save money by drastically reducing cooling costs during the hot summer months.
Minimizing the sun’s impact on the roof surface not only helps sustain lower energy costs as the system ages but also cools internal building temperatures and extends service life.
3. Easy to Install (Pro)
As a water-based substance, acrylics are easy to work with and install. This means an acrylic roof coating system can be installed in a timely manner without sacrificing quality workmanship and with minimal disruption to day-to-day business operations. Also, installation teams will rarely encounter complications with application equipment, making them more productive and efficient.
Of course, as with everything with the good, there comes the bad. Acrylic Roof Coatings are no different. So here are the not so great things about Acrylic Roof Coatings
1. Ponding Water (Con)
Ponding water will negatively impact the performance of an acrylic roof coating. Ideally, these coatings should only be used on sloped metal roofs or roofs with adequate drainage. Installing an acrylic coating on a flat roof can be very problematic if the roof does not drain properly.
Before installing an acrylic roofing system or product, it is important for building owners and managers to consult with a specialist to determine if the roof structure will encounter ponding water situations.
2. Cold Temperature Applications (Con)
Acrylic coatings are a water-based product and are more susceptible to freezing in colder temperatures. At the time of application, the outside temperature must be at least 50°F and rising, for the coating to properly adhere to the roofing substrate.
It’s also worth mentioning that the dry time of an acrylic coating will slow down considerably if the temperature falls below 50°F.
3. Loss of Mil Thickness (Con)
As acrylic roofing systems age, they tend to lose mil thickness as a result of constant weathering and exposure to extreme environmental conditions. Before considering an acrylic product for your roof, ensure that it has undergone proper testing for specific roofing environments and applications.
When it comes to the suitability and performance of a commercial cool roof coating, it’s important to understand the strengths and weaknesses of the chemistry. Overall I’d say Acrylic roof Coatings are a highly effective commercial roofing solution. Are they perfect? No. But Silicone Roof Coatings aren’t either. Like anything, it’s important to evaluate the pros and cons and weigh them to your commercial roof. You can learn about Acrylic Roof Coatings here.
