Plants cultivated on the rooftop inescapably encountering drought and severe heat conditions. This study aimed to evaluate the water-deficit tolerant ability of some ornamental plants for roof garden utility. Non-irrigated rooftop model was constructed in a greenhouse at Mahidol University, Nakhon Pathom province. Fifteen ornamental plants were observed under two conditions, i.e. watering and non-watering, for seven days. Water-deficit tolerant ability was evaluated by beauty scoring. <em>Liriope muscari</em> (Decne.) L.H. Bailey, <em>Cyanotis obtusa </em>(Trimen) Trimen and <em>Allium schoenoprasum</em> L. showed the high tolerance ability to water-deficit by seven days leading to be suitable plants for roof garden by watering once a week. Moreover, <em>Pilea libanensis </em>Urb. and <em>Plectranthus scutellarioides </em>(L.) R.Br. also had high tolerance by five days. The short period plants for three days were <em>Eleocharis </em>sp., <em>Fimbristylis ovata</em> (Burm.f.) J.Kern, <em>Zephyranthes candida</em> (Lindl.) Herb. and <em>Pennisetum setaceum </em>(Forssk.) Chiov., whereas <a href="http://www.theplantlist.org/tpl1.1/record/gcc-135712"><em>Leucanthemum vulgare </em>(Vaill.)
