Which Roof Coating Performs Best?

With so many types of roof coating available in the industry, which one performs best? Ultimately, determining the best solution depends on a variety of factors such as roof type, age, weather conditions, environmental concerns, aesthetics, just to name a few. Below, we take a closer look at some of today's most common types of commercial roof coatings.

Acrylic coatings are among the most durable and inexpensive elastomeric materials in the commercial roofing industry. While most commonly used on metal roofs, they are also a suitable choice for a number of conventional flat roof substrates. They are easy to work with and come in a variety of standard, premium, and custom-color tints.

Liquid-applied acrylic systems are a great solution for commercial roofs. There are some important factors to consider when it comes to choosing this particular chemistry. Follow the link below to learn more about the strengths and weaknesses of an acrylic roof coating.

Another widely popular roof coating material is asphalt emulsion. These products consist of asphalt particles dispersed in water with clay used as a bonding element. Generally black or brown in color, these coatings contain organic and inorganic compounds, and other fillers to add strength and durability.

Asphalt emulsions are inexpensive and easy to apply. They are typically used to level “alligatoring” and other irregularities found on modified bitumen and built-up roof surfaces. While it can be installed as a stand-alone roofing material, it is most commonly used to provide a monolithic foundation for elastomeric coatings with better reflectivity and UV stability. They generally require 3 to 4 gallons per 100 square feet depending on the substrate. However, multiple passes may be necessary to achieve proper results.

Asphalt emulsions are a water-based product. This makes them susceptible to freezing temperatures and can be very difficult to work with during cold weather conditions.

Butyl coatings are best known for their extreme elongation and tensile strength. This solvent-based polymer is highly reflective, fast-drying, and works great for roof maintenance and repair. Due to their low permeability, butyl rubber coatings are most commonly used as a vapor-retardant barrier over spray polyurethane foam systems in cold storage/freezer applications.

These elastomeric coatings are suitable for a variety of commercial roof surfaces including metal, modified bitumen, single-ply, built-up roofs, and spray polyurethane foam. They are typically white, gray, or tan in color and can be sprayed or roll-applied at a rate of about 2 gallons per 100 square feet.

The primary drawback of a butyl roof coating is its low solids content. They require more material to achieve the desired dry film thickness, making it less cost-effective than other elastomeric roof coating products. They can also be challenging to spray and difficult on application equipment.

Silicone coatings are the best choice when it comes to UV stability and resistance to ponding water. They typically have a high-solids content compared to other coating materials and are suited for a variety of roof substrates including modified bitumen, metal, single-ply, EPDM, smooth and gravel BUR, and spray polyurethane foam.

Silicone roof coating systems are among the best restoration solutions for commercial roofs. There are some important factors to consider when it comes to choosing this particular chemistry. Follow the link below to learn more about the benefits and limitations of silicone coatings.

When it comes to strength and durability, urethane coatings are second to none. Compared to other materials, they are more impact-resistant and are better suited to handle pedestrian traffic. They can also able to withstand the natural expansion and contraction (thermal movement) of roof structures and the damaging effects of ponding water.

Polyurethane coatings, in general, are an excellent choice to restore and protect a variety of roof substrates including modified bitumen, single-ply, EPDM, built-up roofs, concrete roof decks, and spray polyurethane foam.
