I’ve been gone from home due to school and work, so I haven’t been around much. My Mom sent me this photo of our garage ceiling. I’m not sure what the cause is. I was wondering if someone can find what the issue is? I was thinking a leaking pipe, but I’m not too sure…

Edit: Thank you all for the guidance, I’m having someone come out to check it out and see what the damage is to my wallet.
