Slopped roof flashing system and method of use

Abstract

A flanged counter flashing unit, flashing system and method is described for weather proofing the juncture of a brick wall overlying a vertical parapet wall and the edge of a sloped roof. The one-piece counter flashing unit of the flashing system has a vertical slit into which is securely fitted the low upstanding side of a J-Channel flashing positioned at the juncture and the vertical leaf member of an L-shaped roof flashing that is flush with the outer face of the upstanding low side of the J-Channel flashing, including a flange section of the counter flashing unit that extends laterally from the top edge of the counter flashing apron and partially over the J-Channel and an apron adapted for overlying the vertical leaf member of the L-shaped flashing. The J-Channel flashing, L-shaped flashing and flanged counter flashing are included in the flashing system of the present invention. According to the method of the present invention, when the flashing system is positioned at the juncture, the brick wall is constructed from within the J-channel so that the counter flashing flange is included in the brick wall. This method eliminates the need for a separate method step of attaching counter flashing to the brick wall at an angle to the horizontal plane of the brick wall after its construction by means of a gouge cut across the brick wall for that purpose.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a flashing system using a novel counter flashing and method adapted for use in buildings in order to weather proof the juncture between a slopped roof and a vertical parapet wall of masonry material. A gable, for example, has two vertical parapet walls extending from the surface of a sloped roof forming a sloping juncture between each vertical wall of the gable and its corresponding edge of the sloped roof. It is imperative to seal this juncture from moisture that can penetrate the framework of the building resulting in the accumulation of moisture contributing to mold growth and decay of the framework. The use of roof transition flashing is therefore required. Specifically, the present invention relates to so-called brick on wood applications where the vertical parapet wall is covered with a masonry wall preferably of brick and mortar forming a brick veneer. [0002] In the conventional method, the brick wall is cons...

Benefits of technology

[0005] The object of the present invention, therefore, is to eliminate the need for the added step of installing counter flashing after construction of the brick wall. It is therefore an object of the present invention to save labor and material costs in the installation of transition flashing for slopped roofs common to many residential structures. According to the present invention, this is accomplished by interfitting specific sections of the J-Channel and L-shaped roof transition flashing with a counter flashing adapted for this purpose before constructing the brick wall. It is therefore an object of the present invention to have all necessary flashing in place prior to starting construction of the brick wall. Accordingly, a one-piece counter flashing with a flange section and a slit is provided so that the brick wall can be built from within the J-channel to include the flange section in the brick wall. The exposed transition flashing sections, such as, the low J-channel side and vertical leaf of the L-shaped roof flashing are securely fitted in the slit of the counter flashing of the present invention and thus protected from exposure. The present invention also includes a method of installing flashing that eliminates the necessity of gouging the brick wall and installing and sealing an anchor in the gouge for removable attachment of the counter flashing apron.

Problems solved by technology

It is imperative to seal this juncture from moisture that can penetrate the framework of the building resulting in the accumulation of moisture contributing to mold growth and decay of the framework.

This system, however, is not suitable in the case of slopped roof transitions because the brick wall and roof edge juncture lies at an angle to the bricks instead of on a horizontal plane parallel to the layout of the bricks.

There are disadvantages, however, that are associated with this method of counter flashing.

First, the gouge in the brick wall, although critical for proper attachment of counter flashing, is frequently crude where cutting is performed through disparate densities of brick and mortar.

As a result, additional labor and material costs are incurred.

The possibility also exists that attaching the counter flashing anchor and sealing it in the gouge or grove of the brick wall is performed improperly, creating an opportunity for moisture penetration into the brick wall.
