roof coating systems

There are many benefits to choosing a new roof over a previously coated one. Not only does this conserve resources and reduce landfill waste, but it improves the environment as well. Plus, many coatings contain low or zero VOCs and meet or exceed requirements for the US Green Building Council’s LEED program in the areas of Sustainable Sites, Energy and Atmosphere, and Materials and Resources. Here are the advantages and disadvantages of different roof coating systems.

Butyl rubber

Butyl rubber roof coating systems are solvent-based, and they can be a great choice for a variety of commercial roofing applications. They offer excellent vapor barrier protection, superior elongation, and tensile strength. Although they are not eco-friendly, they are an excellent choice for cold-storage buildings. Abutyl roof coating is suitable for flat and built-up roofs. It can be applied to seams, vent pipe flashings, air conditioning units, and expansion joints.

Butyl Liquid Rubber is an Energy Star-qualified roof coating. Available in several colors, including tile red, green, and beige, this elastomeric coating is durable and effective at resisting cracking. It also reflects nearly ninety percent of solar heat, making rooftop air-conditioning units more efficient. It also helps reduce roof leaks and protect against algae buildup and ponding water.

Butyl liquid rubber is a great choice for repairs of leaking roofs on steel roll-formed siding. It does not require corrosion-inhibiting primer, making it ideal for marine environments. Dock facilities, which typically see high levels of saltwater, may benefit from a butyl rubber roof coating. Butyl liquid rubber is a great choice for steel storage tanks, both elevated and ground level. It has excellent resistance to cathodic protection, and surface condensation does not negatively impact its performance.

Butyl liquid rubber can be sprayed onto a flat roof or a low-sloped roof. It can also be rolled or brushed onto the surface. Compared to asphalt roof coatings, butyl liquid rubber roof coating systems are inexpensive, easy to apply, and effective in a variety of situations. Andyl rubber roof coating systems are available from TRUCO Coatings, an industry leader in this field for nearly forty years.


While there are a number of pros to a silicone roof coating system, one downside is that it is prone to attract dirt and airborne dust particles. This gradually makes the coating lose its reflective properties and increase its temperature, causing higher energy costs and internal building temperatures. To address this problem, a contractor can apply a silicone roof coating on any existing plane roof. This solution is remarkably easy to use and can reduce many of the common problems associated with a flat roof.

Silicone roof coating systems come in two basic types: solvent-based and low-solids. Solvent-based systems contain 30 to 40 percent solvents and are largely limited in their application and durability. High-solids silicones, on the other hand, do not contain solvents or water, and have excellent adhesion to a variety of substrates. They are particularly well-suited for sensitive building occupants because they emit very low odors.

Another benefit of silicone roof coating systems is that they can enhance existing roofs. While conventional roof coatings may help prevent minor leaks, a silicone roof coating will provide excellent durability. Because silicone cures naturally outside, it eliminates the need for primer. Most contractors prefer a high-humidity environment for the coating process. Furthermore, silicone roof coating systems do not require the use of primer or paint, which can lead to delays in installation and maintenance.

The benefits of using silicone roof coating systems are many. Among these are lower installation costs, low maintenance, and long-term performance. High-solids silicone roof coatings are a popular choice for late-season and sudden rainy weather. However, they are not a panacea for all problems associated with roofs. If a roof is structurally sound, it can be easily recoated, thereby ensuring long-term performance and lower energy costs.

Another benefit of silicone roof coatings is that they are much better than acrylic roof coatings at protecting structures from ponded water. Moreover, they have better tear and ponded water resistance. And because they are applied over an existing membrane, there is no need for ventilation. And since they are environmentally friendly, silicone roof coating systems are a good choice for almost all types of roofs. But, they should be chosen carefully!


If you have a commercial building, you may want to consider investing in an acrylic roof coating system. While some roof coating systems may require expert installation, others can be applied by anyone. And, because acrylic is compatible with many substrates, you don’t need to hire an expert. You’ll save thousands of dollars on maintenance over the years! Listed below are some of the advantages of acrylic roof coatings. Read on to find out how they can improve the appearance of your building!

These roof coating systems are renewable. They can be reapplied every 10 or more years, extending their life. They can also be renewed with maintenance services to increase their waterproofing abilities. And, since acrylic roof coatings do not emit harmful VOCs, they’re also environmentally friendly. That means you’ll be reducing your facility’s environmental impact by cutting down on construction waste. And, you’ll be able to rest assured that you’re not sacrificing waterproofing ability just to make a buck.

The acrylic roofing systems offered by Conklin are both highly durable and environmentally friendly. The RCS-650 is an economical fluid-applied system made with environmentally friendly materials, while the RCS-4000 and RCS-5000 are premium systems with exceptional durability. And since they are also environmentally friendly, they can save you money in the long run, too. The RCS-5000 is a good choice if you’re looking for a roofing system with custom color capabilities.

Another benefit of acrylic roof coatings is that they retain their white luster for longer than silicone. Silicone roof coatings lose their reflectivity over time and tend to accumulate dirt and grime. This reduces aesthetic appeal. And since silicone doesn’t require primer, you can eliminate it if you don’t want to use a primer. However, silicone can peel off easily and is much more expensive than acrylic. So, while the advantages of acrylic roof coating systems outweigh its disadvantages, it’s worth choosing the best option for your building.

A good acrylic roof coating system should meet the requirements for durability. It should not fail a rain test and must also withstand high winds. Regardless of the climate, acrylic roof coatings are the most cost-effective choice for commercial buildings. The benefits of these systems are numerous.

Asphalt emulsion

Traditional solvent-borne bituminous roof coatings are composed of cutback bitumen residue, refined to certain physical properties. The refined asphalt is then mixed with a petroleum solvent, usually mineral spirits, and various fibers and fillers. The blend of the components determines the coating’s physical properties. Asphalt emulsions have been around for 60 years. They are water-bentonite-bitumen-clay blends.

The advantages of asphalt emulsion roof coating systems include their relative affordability, ease of application, and durability. While they are largely cost-effective, they require multiple passes to achieve the desired results. The disadvantage of asphalt emulsion, however, is that it can freeze at extreme temperatures, making it difficult to apply and work with during cold weather. If the original roof is in good condition, emulsions can be applied over it.

Proper preparation for asphalt emulsion roofing systems starts with proper safety measures. Before applying the coating, hoses should be disconnected from the roof and a temporary staging area should be set up. A non-slip tape can be applied over the ladder rungs to prevent slipping. Proper protection for the ladder and coveralls should also be worn when working on the roof. To avoid slipping, be sure to wear rubber boots and coveralls.

While an asphalt emulsion roof coating system can extend the life of an old roof, it’s important to consult a roofing expert before applying one to ensure that it is structurally sound. The coating can fix minor moisture or deck issues, but it can only fix a roof if it has structural integrity. It is also easier to apply than traditional roofing materials and a popular choice among architects and roofing consultants.

An asphalt emulsion roof coating system is a strong, durable, and water-repellent waterproofing system. It is compatible with many existing roofing materials. Western Colloid #298 asphalt emulsion is compatible with many other types of roof systems and has FM 4470 Class 1 approval. This type of asphalt emulsion is comprised of bentonite clay, asphalt, and water. It is applied by using a colloid mill to break down the molecule size. When applied properly, this type of roofing coating can seal seams and stabilize roof substrates.
