 Aby na st\u0159e\u0161e mohla r\u016fst vegetace, je nutn\u00e9 tzv. vegeta\u010dn\u00ed souvrstv\u00ed, kter\u00e1 se skl\u00e1d\u00e1 z n\u011bkolika vrstev umo\u017e\u0148uj\u00edc\u00edch rostlin\u00e1m r\u016fst a udr\u017eet se ve v\u00fd\u0161k\u00e1ch.

Tato vrstva je promy\u0161lena do t\u011bch nejmen\u0161\u00edch detail\u016f a vegetaci je proto mo\u017en\u00e9 p\u011bstovat i na \u0161ikm\u00fdch ploch\u00e1ch.
 
 Podle toho, jak\u00e9 rostliny se pou\u017eij\u00ed, se rozli\u0161uj\u00ed dva typy \u2013 extenzivn\u00ed a intenzivn\u00ed. Extenzivn\u00ed typ obsahuje takov\u00e9 druhy rostlin, kter\u00e9 se p\u0159izp\u016fsob\u00ed extr\u00e9mn\u00edm podm\u00ednk\u00e1m a nepot\u0159ebuj\u00ed pravidelnou z\u00e1livku.

Intenzivn\u00ed naproti tomu vy\u017eaduj\u00ed stejnou p\u00e9\u010di jako zahrada, tak\u017ee zde najdeme velmi rozmanit\u00e9 rostliny, klidn\u011b i ke\u0159e, ovoce a zeleninu.
 
 Zelen\u00e9 st\u0159echy se daj\u00ed realizovat i na \u0161ikm\u00fdch ploch\u00e1ch. Nej\u010dast\u011bji se vyskytuj\u00ed na t\u011bch, kter\u00e9 maj\u00ed sklon 5-45\u00b0, ale za ur\u010dit\u00fdch podm\u00ednek je lze nainstalovat tak\u00e9 na strm\u00e9 plochy pomoc\u00ed konstrukc\u00ed.

I na ji\u017e stoj\u00edc\u00ed domy to samoz\u0159ejm\u011b jde realizovat, pouze se zde mus\u00ed zji\u0161\u0165ovat, zda st\u00e1vaj\u00edc\u00ed konstrukce snese dal\u0161\u00ed v\u00e1hu vegeta\u010dn\u00edho souvrstv\u00ed.
