🌧️ Rain Returns – How WaterRoofs Performs in Autumn Storms

As autumn deepens, storms sweep across Europe, bringing heavy rains, flooding, and rising urban water management challenges. For most cities, rain is still treated as a problem to evacuate as quickly as possible. Conventional rooftops and sealed surfaces funnel water directly into drainage systems, overwhelming infrastructure and increasing flood risks.

But what if every rooftop could capture and use that rain instead of wasting it?

That’s the principle behind WaterRoofs — turning rainfall from a hazard into a resource.

💧 The Stormwater Challenge in Cities

Urbanization has sealed much of the natural ground that once absorbed rainfall. The consequences are clear:

• Overloaded drainage systems during autumn storms.

• Localized flooding when sewers cannot cope with surges.

• Lost resources, as rainwater bypasses evaporation and disappears into pipes.

With climate change intensifying rainfall events, cities urgently need solutions that reduce runoff pressure and restore natural cycles.

🛠️ WaterRoofs: Performance in Autumn Rains

WaterRoofs tiles are engineered to work with rain instead of against it.

• ✅ Retention in micro-channels: Tiles capture and store rainfall on the rooftop surface.

• ✅ Gradual evaporation: Stored water is released naturally back into the air, cooling rooftops and restoring humidity.

• ✅ Flood risk reduction: By slowing water release, rooftops reduce the burden on urban drainage networks.

Instead of contributing to floods, rooftops become buffers that help stabilize the system.

🌡️ Cooling and Comfort, Even in Storms

Heavy rainfall doesn’t erase the problem of heat. After autumn storms, cities often face humidity spikes and temperature swings. By balancing evaporation, WaterRoofs:

• Cools rooftop surfaces by up to 15°C.

• Lowers surrounding air temperatures by 1–5°C.

• Restores comfort by regulating local humidity.

This is a system designed for all-weather performance.

♻️ Circular Climate Infrastructure

Unlike conventional stormwater systems, which simply divert water, WaterRoofs also integrates circular sustainability:

• Made from 100% recycled PET, preventing plastic waste from reaching oceans and rivers.

• Modular and lightweight — easy to retrofit on existing urban rooftops.

• A dual solution: stormwater management + climate adaptation.

🌍 Part of Blue–Green Infrastructure

WaterRoofs fits naturally into broader blue–green infrastructure strategies. It complements:

• 🌿 Green roofs, which add biodiversity and vegetation.

• 🌊 Rain gardens and bioswales, which absorb and filter runoff.

• ☀️ Solar panels, which perform better when cooled by evaporation.

Together, these systems create resilient cities that can withstand extreme rainfall while staying cooler, greener, and healthier.

✅ The Takeaway

Autumn storms don’t have to overwhelm cities. With WaterRoofs, rooftops transform into stormwater allies — capturing, retaining, and evaporating rain while cooling the air and reducing flood risks.

Every drop is a resource, not a waste.
