Flat roofs are a popular choice for commercial and residential buildings due to their modern aesthetic and space-saving advantages. However, they are more susceptible to damage from weather elements and UV rays, leading to leaks, cracks, and premature deterioration. To combat these issues, roof coatings have emerged as an effective solution, with elastomeric coating being one of the most popular choices. In this blog, we will explore the numerous benefits of applying an elastomeric coating on existing flat roofs.

1. Waterproofing and Leak Prevention:

One of the primary advantages of elastomeric coatings is their exceptional waterproofing capabilities. These coatings create a seamless, rubber-like barrier that effectively prevents water from seeping into the roof structure. By eliminating leaks, the coating protects the building’s interior, preventing costly water damage and mold growth.

2. Flexibility and Crack Resistance:

Elastomeric coatings are formulated to be highly flexible, allowing them to expand and contract with the changing weather conditions. This elasticity helps accommodate the natural movements of the roof without compromising its integrity. As a result, the coating resists cracking, reducing the risk of water infiltration and extending the overall lifespan of the roof.

3. Energy Efficiency:

Flat roofs can absorb a significant amount of heat from the sun, leading to increased cooling costs. Elastomeric coatings are designed to have a high solar reflectivity, which means they reflect a large portion of the sun’s rays away from the roof’s surface. By reducing heat absorption, these coatings help maintain a cooler indoor environment, resulting in lower energy consumption and reduced utility bills.

4. UV Protection:

Prolonged exposure to UV rays can cause rapid deterioration of flat roofs, leading to premature aging and degradation. Elastomeric coatings contain UV stabilizers that help shield the roof from the damaging effects of the sun. By reflecting and dispersing UV radiation, the coating protects the roof’s surface, preserving its structural integrity and extending its lifespan.

5. Cost-Effectiveness:

Compared to traditional roof replacement, applying an elastomeric coating on an existing flat roof is a cost-effective solution. The coating process is less labor-intensive and time-consuming, resulting in lower installation costs. Additionally, the coating’s durability and long lifespan reduce the need for frequent repairs and replacements, saving building owners significant maintenance expenses in the long run.


Elastomeric coatings offer a range of benefits for existing flat roofs, making them an ideal choice for building owners looking to enhance the performance and longevity of their roofs. From superior waterproofing and flexibility to energy efficiency and UV protection, these coatings provide a cost-effective solution that can extend the lifespan of flat roofs while reducing overall maintenance costs. Consider consulting with a professional roofing contractor to determine if an elastomeric coating is suitable for your existing flat roof and enjoy the benefits it has to offer.
