Leak proof roof and wall structure for enclosed trailer

Abstract

A leak proof roof and wall structure for use on trailers includes a roof sheet with an angular extension, a roof support beam receiving member, an elongated angular member, a rain lip member, and a formed coved piece. These components are joined together and attached to a side wall and a roof of a trailer. In operation, fluid drains from the roof across the formed coved piece and into an exterior channel where it drains off the trailer. Fluid that leaks between the roof and the formed coved piece may drain via gravity down the elongated angular member and into an interior channel where it is drained off the trailer. Fluid that leaks between the first partial H-channel and the elongated angular member drains through the J-channel of the elongated angular member to the front or rear and off of the trailer.
