2. INTRODUCTION
• A roof garden is
any garden on the roof of
a building.
• Besides the decorative
benefit, roof plantings may
provide food, temperature
control, hydrological benefits.
• Also provides architectural
enhancement, habitats or
corridors for wildlife,
recreational opportunities,
and in large scale it may even
have ecological benefits.

4. TYPES OF ROOF GARDEN
SHALLOW ( ULTRA EXTENSIVE):
• Shallow Roof Garden System
(growth media depth 2.5” to 4") is
ideally suited for areas likely to
receive little maintenance.
• Recommended plants include
sedums, herbs and grasses.
The anticipated weight above the membrane assembly is generally between
4.8 and 6 pounds per square foot, per inch of system depth, in a saturated
state.

5. Medium Depth (Extensive) Roof Garden
System
• Medium Depth Roof Garden System
(growth media depth of 5" to 8")
includes plants such as sedums,
herbs, grasses and other vegetation,
which can grow in this depth of
media.
• Un-irrigated systems can be provided
without difficulty; however, drip,
mist or spray irrigation systems may
be required to support more diverse
plant types or for installations in
semi-arid climates.
• The anticipated saturated weight
above the membrane assembly is
less than 50 pounds per square foot.

7. Materials Needed to Create a Rooftop Garden
• Typical materials for a
rooftop garden may include:
• Plants
• Growing containers
• Growing medium
• Decking or other material
that can be walked on and
• Seating, wildlife features,
greenhouses or composters.

11. Deep (Intensive) Roof Garden System
• Deep Roof Gardens typically
incorporate a planting system requiring
greater growth media depth
(exceeding 8") that requires regular
maintenance, such as watering,
fertilizing and mowing/weeding.
• A variety of plants are
available including turf grass, annual or
perennial flowers, shrubs and even
small trees.
• This system typically requires a
structural concrete roof deck to
support the larger dead load.
• An irrigation system should be utilized
in these assemblies.
• The anticipated weight above the
membrane assembly is generally
greater than 50 pounds per square
foot.

21. Loading Capacity
Calculate amount of weight roof can support. The
weight of soil, decking, people and planters - and
where they are placed - will all depend on the load
bearing capacity of your roof.
these ideas to reduce the load on your roof:
• Mix soil with organic and inorganic matter to lighten
its weight, or use lightweight growing mediums, such
as pre-mixed planting soils.
• Plan for heavier items to be aligned with the building’s
bearing walls, columns and shear walls, which have
the added support of the footings below.

22. Drainage:
• Keeping access to the drainage system free and clear is a
priority.
• can be done on green roofs by maintaining a gravel ring and
filter cloth layer around roof drains and overflow scuppers.
• On rooftop gardens, ensure that any deck strapping or
containers are aligned in such a way that they don’t block
the flow of water to the drain.
• Watch and determine where water flows to on your roof
and ensure those areas and drainage paths are maintained
roof is designed such to withstand pooling of water.
• An added layer of protection should be provided (a drainage
layer) over the roofing membrane to protect it from
standing water that may collect from watering plants.

23. • Maintenance:
• To maintain clear access to the roofing membrane and
drains for maintenance and repair, install rooftop garden
in sections. This can easily be done using containers of
any height or size, arranged in sections on roof.
• Designing rooftop garden in sections will avoid removing
the entire garden area each time the roof needs some
repair work.
• Remember to factor in the weight of each container and
its wet soil weight when designing the garden.

24. Choosing plants :
• Gardening on a roof is quite different from gardening at ground
level. Rooftops have unique and often extreme microclimates.
The amount of sun and wind roof receives will have a direct
effect on what will grow.
• For roof garden consider the amount of time and resources
required for watering and maintaining plants, especially during
the summer.
Sun and Wind — The height and location of building in relation
to surrounding buildings can affect the amount of sun rooftop
garden receives, as well as the exposure to wind.
• Determine the wind and sun conditions on roof and select
hardy plants that can flourish under the conditions rooftop
garden provides your roof.

25. Soil depth — Most plants can grow on a roof as long as
they are provided with an adequate amount of soil to
stabilize and flourish. However, soil depth may be a
limiting factor on some roofs. Make sure to study the
depth of soil required for different species of trees,
shrubs and wildflowers so as to match the right species
with the conditions provided.
Availability of water — Watering during the summer
months should be addressed in advance.
• Summer is when the garden and plants need the
most attention.

26. Other Features :.
a) Composting — Before composting on a roof make sure
to have adequate drainage.
• the roof should support the weight of the compost.
• Rooftop structures should be tolerant of composted
material, and maintenance.
b) Seating —seating is an important consideration. plan for
seating when determining the load bearing capacity of roof.
• containers can also function as seating areas as long as the
fence or railing on roof still meets safety codes above the
container height, or set containers and seating areas at
least one meter (three feet) away from railings and roof
edges.
