16+ Elastomeric Roof Coating Life Expectancy You’ll Ever Need

Posted on

Elastomeric roof coatings have become increasingly popular in recent years as an effective solution for protecting and extending the life of commercial and residential roofing systems. In this post, we will delve into what elastomeric roof coatings are, how they work, and why they are such a popular choice among property owners and roofing contractors alike.

What is an elastomeric roof coating?

An elastomeric roof coating is a type of liquid-applied roofing membrane that is formulated to provide superior protection against the elements, including UV rays, rain, wind, and temperature fluctuations. Made from flexible polymers, such as acrylic or silicone, the coating can be applied to a variety of roofing materials, including metal, asphalt, and single-ply membranes, to form a seamless, watertight barrier.

Elastomeric roof coatings typically come in white or light colors, which reflect sunlight and help to reduce the temperature of the roofing surface, thus reducing energy costs associated with cooling the building. Some elastomeric coatings also contain reflective pigments that can further enhance energy efficiency and help to mitigate the urban heat island effect that can contribute to localized climate change.

How do elastomeric roof coatings work?

Elastomeric roof coatings are designed to form a seamless, thick membrane that conforms to the shape of the roofing surface and moves with the building as it expands and contracts due to temperature changes. The coating’s ability to remain flexible and elastic, even at low temperatures, makes it particularly effective in protecting roofing materials from cracking, splitting, and other types of damage caused by weather and mechanical stress.

In addition to their protective qualities, elastomeric roof coatings can also improve the appearance of older roofs by filling in cracks and gaps and providing a smooth, uniform finish. The coatings can be applied using a brush, roller, or sprayer, and typically require no additional reinforcement or seams, which can be a common source of leaks and other types of damage.

Why are elastomeric roof coatings so popular?

There are several reasons why elastomeric roof coatings have become one of the most popular roofing solutions in recent years:

  • Cost-effective: Compared to other types of roofing systems, applying an elastomeric roof coating is relatively low-cost; it can be applied over an existing roof, reducing the need for costly tear-off and disposal of the old roof.
  • Durable: Elastomeric roof coatings can last up to 20 years or more, depending on the quality of the coating and the condition of the underlying roof.
  • Energy-efficient: Elastomeric roof coatings can help to reduce energy costs associated with cooling the building by reflecting sunlight and reducing the temperature of the roofing surface.
  • Environmentally-friendly: Elastomeric roof coatings can be applied to a variety of roofing materials, reducing waste and the need for landfill disposal of old roofing systems.


If you are looking for a cost-effective, durable, and energy-efficient solution for your commercial or residential roofing system, elastomeric roof coatings may be the perfect choice for you. With their ability to provide superior protection against the elements, improve energy efficiency, and extend the life of your roof, elastomeric coatings are quickly becoming one of the most popular roofing solutions on the market today.
