The most common reason for spraying texture on ceilings is to conceal imperfections, especially because ceilings are so darn diffcult to work on. Orange Peel texture hides less than, say, popcorn or brush-swirls, but it will hide some imperfections. Be sure to replace any tape that fell because the tape helps prevent the seams from shifting. No amount of texture can conceal a broken or sloppy seam because it will eventually reveal itself due to shifting and natural expansion/contraction with normal temparature and humidity changes.
