🌫️ The Invisible Impact: Why Restoring Evaporation Matters for the Climate

Climate change is often discussed in terms of visible disasters—flooded streets, burning forests, melting glaciers. But one of its most powerful and overlooked symptoms is something we can’t see: the decline of atmospheric water due to disrupted evaporation.

Evaporation isn’t just a by-product of heat and moisture—it's a critical engine in the Earth's climate system. And we've been dismantling it, one dry surface at a time.

💨 What Happens When Evaporation Disappears?

Evaporation from natural surfaces like forests, wetlands, and moist soils plays a key role in:

• Cooling the Earth's surface through latent heat exchange

• Moisturizing the atmosphere to support local and regional precipitation

• Regulating cloud formation, air quality, and temperature balance

But with the spread of urban hardscapes—asphalt, concrete, impermeable roofs—we've drastically reduced the Earth's evaporative surface.

🔻 In cities, up to 90% of rainfall is lost through rapid runoff, not evaporation 

🔻 This leads to hotter local climates, longer droughts, and reduced rainfall downwind 

🔻 The result: a vicious cycle of drying ecosystems, heat islands, and disrupted water cycles

🏙️ Cities Without Evaporation: A Climate Blind Spot

According to Copernicus and WMO’s April 2025 report, Europe experienced its hottest year on record in 2024, alongside record flooding and shrinking glaciers. One underlying issue? The water isn’t staying where it falls.

Our built environment is engineered to get rid of water fast—rather than use it to cool, hydrate, and regulate local conditions. That’s a design flaw we can fix.

🌿 How WaterRoofs Restores the Invisible Engine

WaterRoofs is built to bring evaporation back to cities—one rooftop at a time.

Our patented tiles:

• Hold and slowly release up to 750 liters of water/m²/year

• Mimic the evapotranspiration rate of a mature forest

• Reduce rooftop surface temperatures by up to 8°C

• Increase surrounding humidity by up to 12%

  
  

By restoring this invisible process, WaterRoofs contributes to: ✔️ Urban cooling ✔️ Rain cycle restoration ✔️ Microclimate stability ✔️ Biodiversity support

🌍 The Future Is Moist

If climate change is a drying story, the solution must include bringing back water—not just in rivers and reservoirs, but in the air above us.

Evaporation is invisible, but its absence is not. Let’s bring it back, starting with the spaces we’ve dried out the most—our rooftops.
