Extensive Vegetative Roofing Systems

Extensive Vegetative Ply Roofing: Reliable Choice for Businesses

So, what exactly is extensive vegetative ply roofing? This innovative system layers vegetation over a single-ply membrane roofing system. These lightweight, low-maintenance green roofs are perfect for large commercial or industrial buildings. And they’re more than just good-looking—they’re functional.

Kalkreuth brings decades of experience installing high-performance vegetative systems. Whether you’re upgrading a sports facility, hospital, university, or manufacturing plant, our team ensures every layer—from waterproofing to plant selection—is engineered for peak performance and long-term durability.

Extensive Rooftop Gardens Design

Building an extensive rooftop garden is like designing a living system that just happens to sit on top of your building. Done right, it boosts insulation, filters rainwater, and adds serious value to your property—all without the weight and maintenance of deeper garden roofs.

Key Components:

• Soil Substrate: Lightweight, engineered growing media that supports plant life without adding stress to the structure.
• Plant Selection: Hardy, drought-resistant plants like sedum and other low-maintenance varieties thrive here.
• Irrigation Systems: Drip systems and smart controllers to manage water use effectively.
• Structural Support: We calculate your building’s load capacity and design accordingly to ensure safety and compliance.

Features and Installation Process

We handle everything—starting with structural assessments and system planning. Then we manage every detail during the installation to ensure waterproofing, insulation, and vegetation layers are perfectly aligned. Every component works together to protect your roof while turning it into a green asset.

Applications and Energy Efficiency

Extensive systems are great for urban office buildings, hospitals, schools, distribution centers, and massive stadiums. In hot urban areas, these gardens reduce heat absorption, keep interiors cooler, and support local stormwater goals. Plus, they help your building stand out—in all the right ways.

We provide a custom consultation based on:

• Building size and layout
• Local weather and climate conditions
• Budget
• Long-term performance goals

Pros and Cons of Extensive Vegetative Roofs

Pros

• Improved Stormwater Management: Plants and soil soak up rainwater and slow runoff, reducing the risk of flooding and improving water quality.
• Energy Savings: Vegetation insulates your building, lowering energy use in both summer and winter.
• Noise Reduction: The layers help block out ambient city noise, making the interior quieter and more comfortable.

Considerations

• Higher Initial Cost: You’ll invest more initially than you would with a conventional roof—but the long-term savings are significant.
• Maintenance Requirements: While they require less care than intensive green roofs, some weeding, fertilizing, and inspections are still needed.
• Weight Considerations: Not all buildings can handle the added weight without some reinforcement. That’s why structural assessment is step one.
