For commercial property owners in Eau Claire, WI, protecting your building’s roofing system is essential to safeguarding your investment, especially with the area’s variable weather patterns. One of the most effective methods to extend your roof’s lifespan and shield it from the elements is by applying an elastomeric roof coating. This flexible, weather-resistant coating can prevent leaks, reduce energy costs, and delay the need for costly replacements—if applied correctly.

Elastomeric Roof Coating: An Overview
An elastomeric roof coating is a liquid-applied membrane that cures to form a durable, seamless, and elastic layer over your existing roofing system. It’s ideal for commercial buildings with flat or low-slope roofs made of metal, modified bitumen, EPDM, TPO, or built-up roofing. This coating acts as a barrier against rain, UV radiation, thermal expansion, and even minor structural movement.
Its popularity stems from its flexibility, waterproofing abilities, and reflective properties, but its performance is only as good as its application.
5 Mistakes to Avoid with Elastomeric Roof Coating
For the most successful application possible, there are mistakes that are crucial to avoid such as:
Skipping Proper Roof Surface Preparation
A clean roof is essential for any coating to bond correctly. One of the most common and costly errors is applying elastomeric coating over dirty, oily, or mold-covered surfaces. Dust, debris, grease, and moisture can prevent adhesion, leading to peeling or bubbling shortly after application.
Avoid It: Always ensure your roofing contractor performs a thorough cleaning, dries the surface completely, and removes any contaminants before applying the coating.
Applying Coating in the Wrong Weather Conditions
In places like Eau Claire, WI, weather conditions can change rapidly. Elastomeric coatings need dry weather and moderate temperatures to cure properly. Applying during high humidity, rain, or freezing conditions can result in improper curing, causing the coating to crack or wash away.
Avoid It: Plan your application during a forecasted period of dry, mild weather—ideally between 50°F and 85°F. Avoid windy days as well, as windblown debris can get embedded in the wet coating.
Using the Wrong Thickness or Number of Coats
Some property owners or contractors try to save time and money by applying too little product or skipping multiple coats. This shortcut can drastically reduce the coating’s lifespan and effectiveness. Too thin, and the coating won’t withstand weather and UV exposure; too thick, and it may trap moisture, leading to blistering or premature failure.
Avoid It: Follow the manufacturer’s specifications for coating thickness and number of coats. Most elastomeric coatings require two coats plus a primer for optimal results.
Ignoring Roof Repairs Before Coating
A major misconception is that elastomeric coatings can “fix” an already damaged roof. While they can prevent leaks and bridge small cracks, they are not a substitute for structural repairs. Coating over damaged flashing, soft spots, or leaks without addressing the root causes only delays inevitable repairs—and may even void warranties.
Avoid It: Conduct a full roof inspection before the coating process. Address damaged flashing, replace wet insulation, and repair compromised areas first, then apply the coating to seal and protect your repaired roof.
Overlooking Drainage and Ponding Issues
Flat roofs are particularly prone to ponding water, and while elastomeric coatings are water-resistant, standing water over time will compromise any coating system. If ponding is not addressed before application, water can infiltrate through seams or deteriorate the coating.
Avoid It: Fix any drainage issues and ensure proper slope before applying the coating. Your contractor should check for low spots and install or improve drains if needed.

FAQ
How long does elastomeric roof coating last?
When properly applied, elastomeric roof coatings can last 10 to 15 years, depending on weather conditions and maintenance practices.
Can elastomeric coating be applied over existing roofing materials?
Yes, it can be applied over many roof types including metal, EPDM, modified bitumen, and built-up roofs—as long as the surface is clean and properly prepped.
Is elastomeric roof coating resistant to ponding water?
While it is water-resistant, long-term ponding should still be addressed through proper drainage to prevent damage or coating degradation over time.
Does elastomeric coating help with energy savings?
Yes. Many elastomeric coatings are highly reflective, helping reduce heat absorption and lowering indoor cooling demands during warmer months.
