The site impact of the owners’ new pool house was reduced through the installation of an extensive green roof over the entire 2,750 sqft roof surface. The green roof system chosen was the Xero Flor pre-vegetated mat which has a high percentage of plant coverage at the time of installation. The green roof system is relatively lightweight with a thin profile of approximately 3.5 inches. The green roof weighs between 12-15 lbs/sqft when fully saturated. Completed in August 2008.
