Generally roofing types and roofing products are typically divided up into two primary categories steep slope roofing and low slope roofing.
Residential green roof for slope.
The most crucial component of any sloped green roof is the confinement system which holds the growth medium in place during the roof s early stages of development.
Extensive green roofs are generally made up of a very thin layer of soil or other planting medium with shallow root plants like sedum mosses and grasses.
Modern systems help mitigate the heat island effect create habitats filter pollutants sequester carbon and even increase agricultural and amenity space.
Pitches above 9 12 are very highly angled and are designated steep slope roofs.
Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled.

If not properly secured a pitched vegetated roof can erode and slip under heavy rain excessive irrigation or poor plant growth.
The international codes i codes are the widely accepted comprehensive set of model codes used in the us and abroad to help ensure the engineering of safe sustainable affordable and resilient structures.
In the most basic sense green roofs are a layered combination of vegetation and membrane over a building that can help insulate and provide water management.
Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs.
An extensive green roof on the other hand is a thinner lighter version that looks more similar to a standard roof.
Are framed with a steep slope roof pitch.
It can be sloped or flat.
Larger flat roofed applications low slope such as residential condominium complexes row homes and town houses and smaller applications such as residential porch and garage transitions from the main home where the slope of the roof changes dramatically from steep slope to low slope on the same structure.
