The present invention relates to a production method of a roof-lack, mounted on a vehicle roof panel, and including a main body and a hollow profile integrally formed inside the main body and, more specifically, to a production method of a roof-lack capable of reducing weight and cost. The production method of a roof-lack comprises the steps of: producing a hollow profile including a resin composite material using a drawing method and having a hollow unit extending in the longitudinal direction therein; mounting caps to both end portions in the longitudinal direction of the hollow profile to seal the hollow unit; inserting the hollow profile with the caps on both ends into an injection mold; and insert-injecting a main body having the hollow profile integrally formed therein by injecting an injection product to surround the hollow profile.
