Green Roof Irrigation

[Anonymous]

To try to answer the irrigation side of the question, most likely you would need at the very minimum a temporary irrigation system to get things established. The need for irrigation after establishment really depends on the plant selection and overall roof design.

I agree with Marc’s reply. You really do need to seriously consider your species selection well, and what function those species are required for ie. filtration of pollutants or filtration for reduction of roof run-off and stormwater flow reduction etc.
Endemic species in relation to your site is perhaps your first area of research…then consider the exposure to climatic changes due a roof setting – no shelter or minimal shelter from other structures.

Good luck with your green roof development!

You can use ondugreen system at the roof. It also saves water in that egg thing and let you use that water by evaporation again..You may check it from http://www.onduline.com.tr/Urunler/sistem-ONDUGREEN.aspx (see acrobat reader)But it also gives different types of Sedum as an example you’ll see..
I made a flat type roof garden and watered it with irrigarion pipes (with holes in every 40cm) with separated valve.So I could controll the water. After a short time plants covered the pipes so you don’t see them now.I used mesembryanthemum and verbena. They also work in roof gardens.

About irrigation firstly you have to tell us about the angle of the roof. Is it flat or slopy?if its sloopy use parallel dripper lines through the ground. use a Q16cm small valve before each dripper line so you can controll the water..if water is much be sure that it falls..
