Can we install a green roof in the winter?

All About the Right Technology

When we talk about sustainability and energy efficiency, green roofs represent an ideal solution for contemporary projects. But what happens during winter? Many wonder whether a green roof can be installed even in the cold season.

The answer is a definite yes! With an experienced team and the right materials, such a roof can be installed even at low temperatures. In this article, you’ll learn how winter installation works, what aspects to pay attention to, and what benefits projects executed during this period can offer.

Sedum – The Perfect Vegetation for Green Roofs in the Cold Season

The most commonly used extensive green roofs are those with pre-cultivated vegetation mats that include Sedum species — succulent plants from the Crassulaceae family. They can store water in their leaves, giving them high resistance to both frost and high temperatures.

Why Is Sedum a Suitable Choice?

• Cold Resistant – It withstands negative temperatures without losing vitality.
• Requires Minimal Maintenance – During winter, it enters vegetative dormancy, reducing care needs.
• Attractive All Year Round – ODU GreenRoof vegetation mats contain a balanced mix of Sedum species, maintaining a green and uniform look even in the cold season.

The Benefits of Installing a Green Roof During Winter

1. Execution Efficiency

Completing the project during winter removes the need to wait for spring, allowing the roof to be used immediately once the active growing season begins.

2. Improved Thermal Insulation

A green roof creates an additional protective layer against heat loss, helping reduce heating costs.

3. Weather Resistance

ODU GreenRoof Sedum mats are designed to withstand wind, snow, and rain, maintaining strong adherence to the substrate.

4. Efficient Rainwater Management

Even during the cold season, the roof vegetation helps absorb and filter water, reducing pressure on urban drainage systems.

What Aspects Should Be Considered During Installation?

• Suitable Materials – Vegetation mats offer quick coverage, while modular Sedum trays are ideal for efficient installation.
• Minimum Working Temperature – It is recommended that the ambient temperature be at least +1°C to maintain the flexibility of vegetation mats.
• Proper Storage – If installation cannot be performed immediately, the mats should be stored in a frost-free area.
• Team Safety – On slippery surfaces, protective equipment is essential to prevent accidents.

How Do Snow and Frost Affect Green Roofs?

• Snow Protects Plants – It acts as an insulating layer, maintaining an optimal temperature for vegetation.
• Sedum Withstands Frost – Thanks to its succulent structure, it easily tolerates extreme temperatures.
• Drying Is Prevented – The volcanic substrate used in ODU GreenRoof systems ensures efficient drainage and protects plants from dehydration.
