The system including a main water supply line extending along the base or lower margin of the roof and having spaced parallel upright pipe nipples attached to the main water supply line, a plurality of feed lines extending upwardly from the main water supply line parallel to the roof and a plurality of spaced water sprinkler heads operably attached to each of the feed lines. To interconnect the upper end of each upright nipple, an array of roof slope sprinkler fittings is provided, one of which is selected angularly matching the roof pitch. These sprinkler fittings each include an angled hollow body having a female threaded inlet and a female threaded outlet angularly oriented at different standard roof pitch angles one of which will equal the standard pitch of the roof. Each fitting is threadable directly to and between the pipe nipple and a lower end of the feed line. A separate array of roof peak fittings connecting the upper ends of each pair of aligned feed lines may also be provided.
