Water can accumulate on the top of the slide if the slide toppers arenít holding water, so to speak. Take a look after the next rain. If thereís water, lower one end or the other to see if it will drain prior to retracting the slide. If not, get on a ladder with a squeegee on a telescoping pole and remove the water.
