Additional structural support may need to be provided.
Structural requirements for a green roof.
Shallow pitched green roof 5 25 the structure of a shallow pitched green roof differs slightly from the structure of a flat roof.
Structural engineers determine the loading requirements of a roof to resist live loads forces such as snow rainwater rooftop equipment green roofs and maintenance crews as well as dead loads the basic roofing structure and materials.
The basic anatomy of a green roof consists of vegetation growing medium filter membrane drainage layer waterproof root repellant layer roofing membrane support for plantings above thermal insulation vapor control layer and structural roof support.
Green roofs or rooftop solar panels add additional load to a roof and its support system.
The structural requirements for a green roof are the most important aspect to consider.
Of green roofs the fll green roof guidelines guidelines for the planning construction and maintenance of green roofs were developed from the principles for green roofing published in 1982 and have been revised several times since 1990.
The load bearing capacity of a building must be known before planning a green roof wall or facade.
All three types of roofs require specific layers of roofing materials not found on regular roofs.
Because water runs off the roof more quickly a thicker substrate layer is needed.
The substrate gives the right amount of nutrients to the plants so your green roof stays nice and green.
Structural support of the green roof.
Steeply pitched green roof.
Some roofs are finished with substantial architectural build ups such as concrete pavers or stone.
The allowable depth of the green roof is determined by the load capacity that can be allocated to it.
You need to make sure that the structure can cope with the extra weight of your green roof especially when saturated with water.
They are recognized as a bench mark set of guidelines for green roofs in germany.
Read this section carefully before submitting architectural structural plumbing electrical or mechanical plans for a green roof.
A structural engineer s advice is essential to ensure comprehensive design development based on the building s construction condition and weight loading capacity.
For retrofitting a green roof wall or facade it is important to establish.
Removing unnecessary finishes may provide sufficient capacity for a green roof of equal weight.
