Key Takeaways
Elastomeric coatings are durable, flexible, and watertight materials that create a smooth barrier membrane that grows and shrinks with temperature fluctuations to protect roofs against damage.
They provide excellent UV resistance, waterproofing, and reflectance benefits, which lower roof temperatures and eventually save cooling costs.
With proper installation and ongoing maintenance, including inspections and recoating of maintenance coats, they can achieve 20+ years of waterproofing.
Substrate integrity, correct coating thickness, and weather-resistant formulations are the triple combination of long-term longevity.
Elastomeric coatings are sound investments financially, as they are able to increase roof life, decrease repair needs, and offer savings in energy through improved efficiency.
Financial incentives – such as tax credits for reflective coatings – can be sought after by companies to offset their initial costs and economize on energy and property charges.
What Are Elastomeric Coatings?
Elastomeric roof coatings are long-lasting, flexible, waterproofing systems applied to protect roofs commercially. These coatings form an undetectable, heavy membrane that’s designed to flex with the weather.
Core Properties
The elasticity of elastomeric coatings is phenomenal. They stretch a minimum of 100% and revert to their original shape without tearing or damage. Their flexibility allows for structural movement, which protects the roof from stress-related damage. Its tensile strength offers durability, which allows it to be impact- and abrasion-resistant.
The other dominant feature is UV resistance. The coatings defend roofs against the destructive power of sunlight exposure, which can delay degradation and extend roof life. Their ability to be waterproof is significant in areas with heavy rain or humidity. By sealing the surface, they keep water out, which could produce leaks and structural harm.
Reflective elastomeric coatings have an initial reflectance of more than 80% (ASTM C1549). By reflecting the rays, this reflectance lowers roof surface temperatures, saving energy and cooling expenses.
Key Benefits
Energy Efficiency: Reflective properties reduce heat absorption, saving on cooling expenses by 15% or higher.
Extended Roof Life: They shield roofs from water, heat, and UV damage, increasing the life cycle.
Cost Savings: Coating is cheaper than a total roof replacement and has lower maintenance expenses in the long term.
Primary Functions
Elastomeric coatings create a waterproof seal, stopping leaks and water damage. They shield from UV and thermal shock, preserving structural integrity. With a flexible yet durable barrier, they provide roof longevity. Their reflective properties enhance energy efficiency, and they’re a sustainable option.
Achieving 20+ Years of Waterproofing
How to get 20+ years out of waterproofing with elastomeric roof coatings? Premium materials, expert installation, and continuous upkeep are all responsible for longevity and economical living.
Substrate Integrity
The secret to a 20+ year elastomeric coating is substrate preparation. The roof surface should be sound, clean, and dry before coating. Any cracks, holes, or damage should be repaired as weak spots might weaken the holding capacity of the coating.
Substrate material and the coating type must also be compatible with each other—some surfaces need primers so that they can adhere better and ensure even coating. For example, a concrete substrate may need to be coated with a special primer so that peeling is avoided.
Proper Application
Proper use is the key to long life. Following manufacturer instructions guarantees adhesion and coating efficacy. Even coverage is paramount—uneven application can result in thin areas, which can result in early failure.
Specialized professional equipment, like sprayers or rollers, adds consistency. We let each coat cure fully before applying the next to ensure maximum performance. A 30-mil coating applied in lifts with curing will get you up to 20 years of waterproofing.
Coating Thickness
Thickness is your friend when it comes to waterproofing. A 20-mil coating lasts approximately a decade, and a 30-mil coating reaches the 20+ year waterproofing lifespan. Checking thickness with wet film gauges, for example, prevents under-application. Thicker coats may be required in extreme climate regions where the coat is subjected to strong rains or UV.
Regular Maintenance
Periodic annual inspections are an investment in maintaining the performance and reflectivity of the coating. Regular cleaning will prevent debris from accumulating, which will ruin the coating. Periodic maintenance as needed can strengthen the barrier, which will increase roof life. Taking care of micro problems, like hairline cracks, when they’re small, prevents expensive fixes later.
Climate Considerations
Selecting climate-appropriate formulations ensures performance over the long term. For instance, reflective coatings in warm climates are good and reduce heat absorption, but freeze-thaw conditions in cold climates necessitate high elongation materials that are flexible. Elastomeric coatings, with 100% elongation, stretch and shrink with temperature changes without peeling or cracking.
A Better and Stronger Roof
Elastomeric coatings create a long-lasting membrane that is resistant to leaks, harsh weather, and everyday foot traffic. These coatings deliver cost savings by extending the roof’s lifespan and reducing maintenance needs. For businesses, that means less downtime and improved protection for their assets.
