When it comes to sustainability and energy efficiency, green roofs are the perfect solution for modern projects. But what happens in winter? A common question arises: Can a green roof be installed during winter?
The answer is YES.
With a professional team and the right materials, a green roof can be installed even in low-temperature conditions. In this article, we’ll explain how you can install a green roof during the cold season, the aspects to consider, and the benefits projects gain when implemented in winter.
Why Sedum vegetation is the ideal solution for green roofs in winter
Most extensive green roofs are created using pre-cultivated vegetation mats containing resilient Sedum species. Sedum, a genus of succulent plants from the Crassulaceae family, is valued for its ability to store water in its leaves. This feature provides the plants with exceptional resistance to extreme temperatures, whether heatwaves or freezing conditions.
Characteristics of Sedum:
- Excellent frost tolerance: Sedum plants can withstand sub-zero temperatures without losing vitality. This makes them ideal for green roofs during winter.
- Low maintenance requirements: During winter, Sedum naturally enters a vegetative dormancy phase, reducing the need for care. No irrigation or interventions are required until spring.
- Year-round aesthetic appeal: EcoStratos vegetation mats include a balanced mix of Sedum species, carefully selected to maintain a fresh, green, and uniform appearance even during the coldest months, enhancing your project’s beauty and functionality.
Benefits of installing a green roof in winter
1. Optimized construction timeline
Installing a green roof during winter allows the project to be completed without waiting for spring. This ensures the roof is ready for the active growing season, providing builders with scheduling flexibility and enabling beneficiaries to enjoy all the advantages of a green roof as soon as spring arrives.
2. Enhanced thermal insulation
A green roof provides additional insulation in winter, reducing heat loss through the roof. This insulation helps maintain a consistent indoor temperature, lowering heating costs and increasing the building’s energy efficiency.
3. Weather resistance
EcoStratos Sedum mats are designed to withstand strong winds, heavy snow, and rainfall. The complete system prevents soil erosion and keeps the plants securely anchored to the substrate, even in harsh weather conditions.
4. Rainwater absorption
Even in winter, a green roof reduces pressure on urban drainage systems. The vegetation absorbs and filters water, preventing accumulation and overloading drainage infrastructure. This is particularly important in urban areas where effective rainwater management can prevent local flooding.
What to consider when installing a green roof in winter
The choice of materials is critical to the project’s success. Pre-cultivated vegetation mats offer immediate coverage with well-developed plants, while ready-made Sedum modular trays provide a flexible and efficient solution for quick installations.
- Dormant root systems: During winter, plant roots are inactive and become fully active only in spring. Therefore, it’s essential to carefully unroll the vegetation mats to prevent plant damage, as root regeneration occurs with the arrival of warmer weather.
- Temperature considerations: Sedum mats should be installed at ambient temperatures of at least +1°C to maintain flexibility during handling and ensure maximum contact with the substrate. Checking weather conditions is crucial, as prolonged severe frost can delay installation.
- Storage: If immediate installation isn’t possible, Sedum mats must be stored in a frost-free space to prevent damage.
- Safety: In icy or slippery conditions, ensure the installation team’s safety by using appropriate protective equipment to avoid accidents.
The impact of snow and frost on green roofs
Snow acts as a natural insulator, protecting plants from frost by serving as an additional layer of insulation. It maintains an optimal temperature for vegetation, even in harsh conditions.
Regarding frost, Sedum easily withstands extreme temperatures thanks to its succulent structure. However, in spring, plants require adequate water and nutrients to regenerate and return to peak vitality.
Another key benefit is the minimal risk of drying out. The volcanic-origin substrate used by EcoStratos has excellent absorption properties, preventing plant dehydration and ensuring optimal drainage during the transition from winter to spring.
