commercial roof coating

Before applying a commercial roof coating, any repairs must be completed on the structure of the roof. This includes the repair of sheet metal, removing wet insulation that was left behind by previous leaks, and repairing any protrusions that may have caused them. Once the roof has been repaired, the roof coating will seal up all the imperfections. Next, clean the roof of all debris. Using a power-washer is ideal, but any other method will work.


Commercial roof coating prices depend on materials and labor. Materials used in roof coating tasks are generally similar, though prices may differ depending on brand and type of roofing material. Labor costs vary depending on the type of roof, the size and condition of the structure, and how much time is required to achieve the desired layer thickness. The more expensive solvent-based coatings will require more care during application and can be expensive. However, water-based coatings tend to be less expensive, but they may not last as long.

The cost of modified bitumen roof coating is about the same as the cost of an EPDM roof. The roofer will apply a primer to ensure proper adhesion. This roofing material costs approximately $1.60 per square foot, including materials and labor. While there is no fixed cost for a commercial roof coating, the price ranges from $0.80 to $2.25 per square foot, depending on the brand and the desired thickness. The most expensive materials are silicone, elastomeric polyurethane, and modified bitumen.

Application methods

There are three main application methods for elastomeric commercial roof coatings. The most effective method will depend on the type of roof and construction. In addition, the time of year and temperature may influence the best application methods. The most common application methods will vary by manufacturer and can also be adjusted according to the conditions. If you are unsure of how to apply a coating, consider these three tips for a successful project.

Ensure that the surface is completely dry and free from any contamination before applying the coating. Any contaminates will inhibit adhesion and result in disbondment. To remove heavier debris or remnants of previous coatings, power wash the surface. Apply the coating according to manufacturer’s recommendations. Then, allow it to dry overnight. If the surface temperature is too high or too low, the coating may not bond properly or may cause streaks.

Resistant to ponding water

If you’re concerned about ponding water, consider getting a silicone or acrylic roof coating. These types of coatings remain bonded to the roof even if it gets wet, and are excellent for preventing water damage. Ponding water can damage a roof and cause mold growth, as well as deteriorate the insulation and structural materials inside. Moreover, commercial roofs take a beating from the elements. Standing water and poor drainage can cause roofs to prematurely deteriorate.

Getting rid of ponding water is crucial to protect your building from leaking. This condition can lead to a vicious cycle. Water tries to find its way to the ground, and any holes in the roofing system will be quickly exploited by ponding water. In addition to affecting your building’s structural integrity, ponding water can also cause the roof to sag. As a result, you’ll have a problem with costly repairs.

Environmental impact

As more people are becoming aware of the environment and the issues it faces, more manufacturers are turning to environmentally-friendly products. Building regulations are also becoming more strict. The benefits of a cool roof coating are not only financial, but also environmental. The installation of a new roof requires tons of waste and materials. However, with a roof coating, these wastes and materials are not wasted at all. Commercial buildings can be made more energy efficient, which in turn reduces the environmental impact.

Moreover, a new roof can be quite expensive, so a coating can prolong the life of an existing one. A high-quality roof coating will extend its life and save you money by lowering your energy bill. Besides, a roof coating will protect the substrate from weather and thermal cycling, reducing the need for replacement. Thus, a high-quality roof coating can extend the life of your roof and prevent the building from requiring replacement anytime soon. Another advantage of a high-quality roof coating is that it does not add to landfill congestion.
