Cabinate Ceiling ripply

I currently bought a used trailer. and unfortunately found in the cabinet a little bit of a rippley ceiling . No discoloration . Very dry still . board seems pretty hard still .So I went out side and checked the roof seems solid no rips or soft spots .Maybe it was once water damaged inside the cabinet at one point not sure . I was wondering Do you guys think its worth cutting it out and checking behind it and removing the old insulation or something . Its a 2002 jayco eagle 5th in pretty decent shape were the ladder is on the back of the trailer is there's very slight delamination not bad but that's kinda the area were this spot is were the ladder connects to the roof . Really just looking for any suggestions . Since im new to the rv world .


thank you very much everyone for taken the time to read this
