Hello! As the title reads, my entire ceiling leaks, it seems. I just bought a brand new 12x12 Kodiak cabin tent. I bought it because my last tent got destroyed in a tornado. I rent this out as a Aironb. So the night i put it up, it happened to rain. When I went in it afterwards it appeared the whole ceiling was wet. When I touched it, it was wet. And when i flicked the ceiling, the entire ceiling dropped water on the floor. Like I said, this tent is brand new. No rips. Am I supposed to water proof it? Any help would be great. Thank you!
