<li>The lightweight material is more prone to wind erosion, and this should be accounted for in the initial design, alternatives include erosion control blankets, soil tackifiers, or Sedum mats. </li>

<p>Increasing the depth of planting medium from 100 mm to 150 mm has been shown to benefit the vegetation[http://www.sciencedirect.com/science/article/pii/S0301479713006051]. Stormwater retention was not improved with this increase in depth[http://ascelibrary.org/doi/abs/10.1061/(ASCE)HE.1943-5584.0001534].

<p>Regular irrigation has been shown to substantially reduce the stormwater capture benefit of an extensive green roof[http://ascelibrary.org/doi/abs/10.1061/(ASCE)HE.1943-5584.0001534]. One way to reduce the irrigation used on green roofs is through the use of electronic technologies. Responsive sensors that suppress irrigation after a rainstorm are routinely attached to green roofs to conserve water. Improvements can be made by instead using a 'soil' moisture sensor to trigger irrigation. State-of-the-art management systems now use predicted weather data to prevent irrigation ahead of storm events[https://optirtc.com/products].
