The primary goal of a root barrier is protecting
the watertight integrity of the roof membrane
and keeping root growth from spreading to
unintended areas.
Root barriers can vary, depending on the type
of plants. For species with aggressive root
systems, asphaltic sheets with an embedded
repelling agent, or heavy duty thermoplastic
sheets with taped or overlapping seams are
used to prevent root penetration.
For plants with less aggressive root systems,
standard duty thermoplastic sheets are
installed, again overlapped at the seams.
Insulation
The insulation of choice for a green roof in a
protected membrane assembly is Extruded
Polystyrene Insulation due to its many
favorable features and benefits including:
Excellent performance in wet applications
Dimensionally stable
High thermal value
Good compressive strength
Environmentally friendly

Drainage / Retention Elements
The delicate equilibrium between over-
watering and not providing enough water can
be challenging enough with common
houseplants.
The scale is greater on a roof top, but the issue
is the same.
Moisture retention and drainage panels that
incorporate both a reservoir system and
drainage channels are located beneath the soil,
under a filter fabric, in a well-designed green
roof.

Drainage / Retention Elements, cont’d…
The drainage and moisture retention layer plays an
essential part in storing rainwater that filters
through the growing media.
One component, which looks like an egg crate
(lower image, previous slide), works as follows:
drainage channels above and below ensure that
excess water is free to drain out of the system
(top image). The profile of the components also
provides water storage troughs that retain (or
store) additional water for use by the vegetation.
Diffusion holes through the panels allow air
circulation and water vapor to move up into the
root zone of the soil (bottom image).
In an extensive roof located in drier, hotter
climates, a moisture mat can be added to the
system assembly to absorb and store additional
usable water.

Filter Fabric
In a properly designed green roof, a filter sheet
should be placed between the growing media
and drainage/retention panels.
A geotextile filter sheet is made of non-rotting,
non-woven polypropylene fibers.
Properties of a filter fabric include high
resistance to all natural acids and alkalis, and
it should be chemically neutral.
