==Inspection Maintenance==
 +
Green roof maintenance is typically greatest in the first two years as plants are becoming established. Vegetation should be monitored to ensure dense coverage becomes established. A warranty on the vegetation should be included in the
 +
construction contract.
 +
Regular operation of a green roof includes:
 +
* [[Green roofs#Irrigation|Irrigation System]]: Watering should be based on actual soil moisture conditions as plants are designed to be drought tolerant. High soil moisture from unnecessary watering will reduce the runoff reduction benefits of the green roof.
 +
* [[Green roofs#Design|Leak Detection]]: Electronic leak detection is recommended. This system, also used with traditional roofs, must be installed prior to the green roof. Particular attention to leak detection should be paid in the first few months following installation (The Folsom Group, 2004).
 +
Ongoing maintenance should occur at least twice per year (Magco, 2003) and should
 +
include:
 +
* [[Planning Considerations#Design for Maintenance|Weeding]]: Remove volunteer seedlings of trees and shrubs. Extensive green roofs are not designed for the weight of these plants, and the woody roots can damage the waterproofing.
 +
* [[Green roofs: Planting|Debris and Dead Vegetation Removal]]: Debris and bird feces should be removed periodically. In particular, the overflow conveyance system should be kept clear.
