Disclosed is a flashing for weatherproofing an aperture made in an inclined roof to allow passage of a vertical member such as chimney through the inclined roof. This flashing has a base member adapted to be mounted over the aperture and a surrounding member that is tubular in shape and extends upwardly from the base member to fit around the vertical member. The base member comprises a covering panel of quadrilateral shape having a top edge adapted to be positioned on an upper part of the inclined roof, a bottom edge adapted to be positioned on a lower part of the inclined roof, two opposite side edges and an opening large enough to allow passage of the vertical member therethrough. A bottom side wall projects downwardly from the bottom edge of the covering panel and two lateral side walls respectively extend downwardly from the opposite side edges of the covering panel and sidewardly from the bottom side wall in a tapering fashion. The covering panel, bottom side wall and lateral side walls together defines a hollow housing. This flashing can be installed by (1) cutting a slot in the upper part of the inclined roof above the aperture made therein, so as to receive the top edge of the covering panel of the base member, (2) inserting the top edge of the covering panel into the slot cut in the inclined roof (3) positioning the bottom side wall of the base member onto the lower part of the inclined roof in such a manner that the bottom opening of the surrounding member is located on top of the roof aperture; and (4) fastening the base member to the inclined roof. Thanks to its particular structure and the way it is installed, the flashing according to the invention may be installed in a very easy and efficient manner on any kind of roofs, including inclined roofs with a corrugated structure defining downwardly oriented ridges.
