What is a Green Roof?

Green roofs are vegetated roof covers that take the place of bare membrane, gravel, shingles or tiles. There are many variances of green roof types, but all green roofs include:

  • A waterproofing system
  • A drainage layer and soil and or/plants
  • Concrete roof pavers/ wooden roof decks

Extensive:

  • Low-profile and include fewer layers than an intensive system
  • Soil depth from 2”-6”
  • Lightweight: 15-50lbs/sq.ft
  • Limited plant species options
  • Less expensive and require very little maintenance
  • Can be constructed on slopes up to 30 degrees and steeper ones can be installed with raised grids or laths to hold plants and soil media in place

Intensive:

  • Soil depth 6” or more
  • Heavier weight load on roof: up to 150 lbs/sq.ft
  • More plant species available including trees and shrubs
