The Energy Saving Effect of White Roof Coatings

When considering home energy savings, we usually focus on windows, insulation, or HVAC systems. But there’s one key surface that’s often overlooked, and it’s right above your head.

Your roof can be a powerful tool in cutting down energy costs, especially in hot, sunny climates. When it comes to maximizing that potential, white roof coatings are leading the charge.

What Are [White] Roof Coatings?

White roof coatings are reflective, protective layers applied to your existing roof. Unlike traditional dark roofing materials that absorb heat, these coatings bounce sunlight back into the atmosphere, reducing the amount of heat your roof, and your building, receives.

That difference in comfort is noticeable, right? That’s exactly what happens with your roof.

So How Do They Save Energy?

By reflecting solar radiation, white roof coatings lower roof surface temperatures by up to 50°F. That translates into:

• Lower indoor temperatures, especially on the top floor

• Less strain on your air conditioning system

• Reduced energy bills, particularly during peak summer months

In commercial buildings, the savings can be dramatic. In homes, especially in warm regions like Florida, the comfort and cost benefits are just as real.

The best part? You don’t need to replace your roof. Coatings like Lanco’s white elastomeric roof sealers can be applied directly to many existing roofing materials, creating a seamless, weather-resistant, energy-saving barrier.

If you live in a hot, sunny climate, or have a flat or low-slope roof, white roof coatings are a smart, cost-effective upgrade. They're easy to apply, require minimal maintenance, and start delivering benefits immediately.

Whether you’re a contractor looking for better solutions or a homeowner tired of sky-high summer bills, a white roof coating might be the coolest investment you make this year.
