🧩 Modular by Design: The Technical Architecture of WaterRoofs

In the search for scalable, climate-positive infrastructure, modularity is more than a construction feature—it's a strategic advantage. The WaterRoofs system, developed by inventor Igor Ustinov, is a patented evaporative roofing technology that reinvents how rooftops interact with water, air, and heat.

Its defining characteristic? A modular system of interlocking tiles, inspired by the simplicity and precision of LEGO, combined with advanced ecological engineering.

🔧 How the Modular System Works

Each WaterRoofs tile is designed to fit seamlessly with others, forming a continuous, uniform surface that mimics the natural texture of forest canopies. The tiles lock into place via a custom-engineered tongue-and-groove system, which:

• Ensures structural stability across varied roof inclinations

• Allows for rapid, tool-free installation and replacement

• Supports uniform water retention and controlled evaporation across the surface

This interlocking design also makes WaterRoofs ideal for retrofitting existing roofs or integrating into modular housing systems, including collaborations with UHCS (Ustinov Hoffmann Construction System).

♻️ Engineered in Recycled PET: Sustainability Meets Performance

Each tile is made from recycled polyethylene terephthalate (PET)—a lightweight, UV-resistant plastic commonly used in beverage bottles. The selection of PET is both intentional and strategic:

• ✅ Recyclability: PET is globally recycled and widely available

• 🔥 Thermal stability: Performs reliably under sun exposure and temperature shifts

• 💧 Hydrophobic properties: Prevents mold or waterlogging while supporting precise evaporation

• ♻️ Circular economy alignment: Gives a second life to thousands of PET bottles per installation

This material, when shaped into the WaterRoofs geometry, creates a micro-channel surface profile that retains rainwater in fine grooves.

💧 Water Capture and Controlled Evaporation

WaterRoofs tiles do not simply repel water like traditional ceramic or bitumen tiles. Instead, they are engineered to retain and manage it. Here’s how:

1. Water Retention: Horizontal grooves and internal capillary channels hold a thin layer of rainwater per tile

2. Evaporative Release: As sunlight heats the tile, water gradually evaporates—reducing surface temperatures and reintroducing moisture to the atmosphere

3. Overflow Management: Integrated micro-slopes or perforations guide excess rainwater into safe drainage or greywater systems when the grooves are full

This process mimics the evapotranspiration found in forest ecosystems. With up to 750 liters of evaporated water per square meter per year, WaterRoofs act like a living layer on the built environment.

🧠 Adaptive by Climate Zone

Modularity doesn’t stop at shape—it extends to function. WaterRoofs can be adapted to regional climate data, using predictive analytics. For example:

• In arid zones, grooves are deeper to hold more water and extend evaporation duration

• In humid zones, surface treatments minimize biofilm growth while sustaining release

• In coastal regions, overflow is directed into collection tanks or gardens

This makes WaterRoofs not only modular in form, but modular in function—a truly adaptive roofing system.

🏗️ Built for the Future

WaterRoofs combines nature’s logic with modular engineering:

• Light enough for fragile roofs

• Durable enough for industrial use

• Scalable enough for urban implementation

Whether used in public buildings, homes, modular units, or industrial sheds, this system delivers more than shelter—it delivers climate value.

For architects, planners, and cities seeking resilient, nature-integrated infrastructure, WaterRoofs offers a drop-in-ready system for a world that can’t wait.
