Commercial roofs may look similar from a distance, but there are actually several important options to choose from. Which one will be best for your building depends on factors like the environment, expected wear levels, whether or not the roof is meant to help keep the building cool, budget, and more.
In this post, we will discuss the top coating options for flat commercial roofs. Coatings keep the roof sealed against leaks. The other benefits they provide depend on the type of coating involved.
These are currently used on a wide variety of roofing systems, from single-ply membranes to metal roofs. They provide great resistance to solar radiation and hail while maintaining the flexibility needed to handle the instability of most roof membranes. Not only that, they can reduce the temperature of a building by 20 degrees when there is direct sunlight and the ambient temperature is over 85 degrees.
These are made of 100% silicone, making them highly elastic. Silicone coatings have high adhesion and remain flexible for years. Usage of these coatings has increased due to their ability to withstand ponding water without breaking down and springing leaks. However, cost, application requirements, and the likelihood of time-related surface dulling often keep them from being used where their ponding tolerance is not needed.
Polyurethane coatings were originally intended to be used on sprayed-in-place foam membranes, but now, they are used in a variety of roofing systems. They are best for foot traffic and impact resistance. Typically, these coatings are applied in two forms on the same roof. The lower layer is the “aromatic” coating and provides durability. Meanwhile, the upper layer is the “aliphatic” coating, which provides UV stability, grime resistance, and long-lasting color.
Fluid-Applied Asphaltic Rubber Membrane System
This has come into popularity in response to labor shortages. It is used to extend the life of existing roofs rather than to create new ones, and can also be used for repairs. It combines the elasticity of rubber with the waterproofing and weatherproofing abilities of asphalt. When dry, the coating can range from 20 mils to 200 mils. It dries quickly to produce a seamless coating that provides instant protection.
