The present invention provides an exterior wall frame construction for excluding rain, the construction having a frame and a water stop. The frame has a head, a sill, and two jambs. The two jambs are each connected to the head and the sill for holding a door or a window. The water stop is located at the head of the frame. The water stop has a top surface, a front sidewall, a rear sidewall, and a pair of end caps. The front sidewall extends upwardly from the top surface to form a barrier against water leaking over the frame from the exterior of the structure. The front sidewall has at least one weep hole located adjacent to the top surface, the weep hole being a conduit through the front sidewall allowing water to drain from the water stop to the outside of the building. The top surface is preferably slanted downward from the rear sidewall to the front sidewall, so that any water leaking onto the top surface runs down to the front sidewall and out the weep hole. In various embodiments, the water stop is either attached to or integral with the head of the frame.
