Sloped Roof Considerations

 Review Green Roof 101 for basic information on any type of green roofs.


realisation-forte-pente-hp-deauville-76-2When designing a green roof on sloped surfaces it is important to be aware of the related technical constraints. These constraints should be considered during the design phase of any sloping green roof.  The experts at Vegetal i.D. can help to make any sloping green roof project a success.

Plant Erosion

During the plant's establishment period, erosion can be significant on highly sloped roofs. For this reason, cuttings or plugs should be avoided in these applications. The Acropack system integrates Vegetal i.D.'s all-in-one Hydropack system which is delivered with established plants and at least 90% coverage in order to minimize any risk of erosion.

Growing Media Erosion

Growing media should be protected from eroding in case of a strong rain event. To prevent erosion, the Hydropack system drains well while retaining the growing media within an appropriately sized tray to prevent erosion thanks to its integrated edge.

Water availability

Hydropack modules are designed with a water reserve to increase the water retention of the system and water pathways help the irrigation to be efficient. On a pitched roof, water availability is considerably decreased. We recommend installing an irrigation system with sprinkler or drip regardless of the geographic location. The experts at Vegetal i.D. can help you to design the appropriate irrigation system for your specific situation and climate region.


Maintenance is important as these roofs are often highly visible. A maintenance program must be scheduled for a minimum of 6 times a year. You can contract Vegetal I.D.'s expert team to do the maintenance of your project or help to establish an appropriate maintenance program.
