Green Roofs Defined

A green roof is a supplemental roofing system that covers a conventional roof with a layer of vegetation.  There are two basic types of green roofs.

Extensive Green Roofs

Extensive green roofs generally use low-maintenance vegetation such as sedums or short grasses. They are less than six inches deep and are typically 2-4 inches in depth.  Their light weight makes them ideal for retrofit projects on older buildings or any structure with limits on the total weight load.  Generally, extensive green roofs require minimal maintenance and can thrive in most temperate climate zones.

Intensive Green Roofs

Intensive green roofs are deeper, which allows for more types of plants and increases potential stormwater retention.  Heavier and more expensive than extensive green roofs, intensive systems generally require higher maintenance.

XeroFlor Green Roofs 

The XeroFlor green roof systems are extensive.  The key components of the XeroFlor systems are thin, light weight, pre-vegetated mats that roll out like sod.  A modular version of the system is also available.  XeroFlor green roof systems incorporate a proven, textile-based design developed in Germany and improved over decades of ongoing R&D.  In Europe, where the green roof industry is long-established, XeroFlor is the technology of choice.  In North America, XeroFlor has been installed in 38 states and all provinces of Canada since 2002.
