Green Roof Slope Design

These systems are presented in the guide in relation to habitat water management energy needs and other factors affecting a project s design.

Green roof slope design.

Contact hydrotech for specific requirements. However some slope is needed to promote positive drainage and prevent ponding and or prolonged saturation of the growing media. To support the weight and handle the wear and tear from constant foot traffic the design team specified a beefed up version of a typical green roof system. Green roofs are now feasible in sloped applications with hydrotech s gardnet option a growing media confinement component within the garden roof assembly.

Depth 3 5 13 of growing media visibility can be an architectural design feature. It all comes down to the design as well as the types of plants that are added to the green roof. Gardnet allows design professionals to expand beyond traditional flat roof applications and put a green roof in places they never could before. Green roofs can be installed on rooftops with slopes up to jmr if baffles grids or strips.

One important item to design for is an increased structural load. 0 5 roof angle green roof systems according fll without additional support. Roof slope treatment volume is maximized on relatively flat roofs a slope of i to jr. Plants that are used often with this treatment are ones that are tolerant to droughts including certain sedums succulents a few types of grass and mosses.

1 7 determine green roof financial incentives available for project site. 5 15 roof angle systems with optional support depending on project. About 50 of the roof is at a 2 12 slope providing a fairly comfortable climb for visitors says blau. 1 1 determine project budget.

1 9 determine type of green roof desired based on goals constraints and budget. Any large slope or flat roof that s hard to reach makes a great area for this kind of vegetation as nature will take care of itself. This means that you can have a green roof that s best suited for flat surfaces slanted roofs and more. 1 4 estimate design installation and maintenance costs.

1 6 determine project timeline. There are a number of things to consider when designing for a green roof. 15 45 roof angle appropriate measures to cope with shear forces and erosion green wall. Usually mosses succulents bulbs and tubers grasses herbs herbaceous and woody plants are recommend for green roofs.

Features of garden roof assembly for sloped applications. 1 5 conduct lifecycle cost analysis. Support a green roof.
