Narrative:
During our arrival and approach we picked up ice. In my post flight; as the first officer; I informed the captain about the ice that was still on the wings; tail; and propellers. During that time the ground crew asked me if we needed deice. I told them that we would if conditions remained the same; but to ask the captain. During my preflight I saw ice still on the leading edge of the wings; horizontal stabilizer; propellers; and vortex generators of the vertical stabilizer. I informed the captain of this when she came to the airplane. After start; I asked the captain if we were deicing. She said we were not. I brought up the ice on the airplane to her again. She said there wasn't enough to require deice. I reminded her about the clean aircraft requirement relative to icing. She said; 'we are not deicing.' I told her that; 'I am not comfortable leaving.' after some further discussion; she told me that I needed to call for deice. I called the deice company and we were deiced with type I; the appropriate checklists were run; and no further complications relative to the deice arose.
