It would be nice if you list the year, make and model number of your RV in your profile. There may be someone on the forum with the same problem and can tell you what they had done. If the RV is new take it to the dealer for repairs under warranty. If you bought it used have you been on the roof to check the condition? There are so many variables that pictures will help others know exactly what your problem is.
