Elastomeric roof coatings: the what, the why & the type

If you’re a property owner or contractor in Florida, you already know: the sun, the rain, and the heat don’t go easy on your roof. That’s why at Lanco Roof Products, we believe in making roofs not just last longer, but perform better. One of the smartest ways to do that? Elastomeric roof coatings.

The What: A Second Skin for Your Roof

Think of elastomeric coatings as a flexible shield that covers your roof. Once applied, they form a seamless, waterproof barrier that moves with the roof as it expands and contracts with temperature changes.

The result? A restored roof that reflects heat, resists leaks, and gives your existing system a new lease on life—all without the mess and expense of a full replacement.

The Why: Why Choose an Elastomeric Coating?

At Lanco, we see coatings as more than a “patch job.” They’re a smart investment with benefits that go beyond just keeping out water:

• Save on Energy Bills: Many coatings are reflective, bouncing back Florida’s harsh sun. That means lower roof surface temperatures and less strain on your air conditioning.

• Extend Roof Life: UV rays and ponding water are roof killers. Coatings add a layer of protection that can push replacement costs years down the road.

• Lower Cost, Less Hassle: A coating project usually costs a fraction of a tear-off and doesn’t shut down your building in the process.

• Sustainable Choice: Restoration means less waste in landfills and a greener option for your property.

Simply put, coatings let you work smarter with the roof you already have.

The Types: Picking the Right Coating for the Job

Not all coatings are the same, and choosing the right one makes all the difference. Here’s our take:

Acrylic

• The go-to choice for many roofs.

• Great for reflectivity, easy to apply, and cost-effective.

• Works best where drainage is good—if you have ponding water, it’s not the top pick.

Silicone

• The ponding water champion.

• Flexible, UV-resistant, and tough in Florida’s rainy seasons.

• Does attract dirt over time, so occasional cleaning is smart.

Polyurethane

• The tough one.

• Handles heavy foot traffic and chemical exposure better than others.

• Often used as a topcoat on sprayed foam or high-wear areas.

Asphalt-Based & Aluminum-Pigmented

• Traditional, budget-friendly options that pair well with older bitumen systems.

• Aluminum versions add reflectivity, but they don’t offer the same elasticity as acrylic or silicone.

Our Take at Lanco

When contractors ask us which to use, our advice is always the same: let the roof tell the story.

• Got standing water? Lanco's Siliconizer 1000® is your best friend.

• Want maximum reflectivity at a great value? Acrylic is hard to beat.

• Need durability in a high-traffic or industrial setting? Polyurethane has your back. [Hyperlink to Urethenizer]
