Abstract

A method of using flashing having a counter flashing member and preferably fabricated from one piece of material is described for weather proofing the juncture of a building at the edge of a sloped roof covered with shingles and a vertical wall covered with a masonry veneer. The flashing is positioned above the surface of the roof by resting it on a fabricated support positioned at the juncture so that the counter flashing member is extending downward to the roof surface overlapping the vertical flashing member of a shingle-based flashing, such as, step flashing protruding from and above the surface of the roof and flush with the support. Construction of the masonry veneer is begun atop the support with a section of the flashing being interposed between the bottom of the masonry wall and the fabricated support after the flashing, including its counter flashing member, has been properly positioned to cover the support and the vertical flashing member protruding from above the surface of the roof, thereby eliminating the need for separately attaching a piece of counter flashing to the masonry veneer after it has been constructed to overlap the protruding vertical flashing member.

Claims

1. An improved method of using flashing for weather proofing a building at the juncture of the edge of a sloped roof and a vertical wall, wherein the sloped deck of the roof is covered with shingles combined with a shingle-based flashing having a bent-up leaf member protruding above the roof surface for sealing the juncture, and the vertical framed wall is covered by a masonry wall and counter flashing is used to overlap the bent-up leaf member of the shingle-based flashing to complete the sealing of the juncture, the improvement comprising the steps of:

(a) positioning a fabricated support on the roof deck at the juncture so that the support extends the length of the juncture and parallel to the slope of the roof and is flush with the bent-up leaf member and the vertical framed wall of the building;

(b) covering the fabricated support with a flashing having a counter flashing member so that the flashing is resting on the support entirely above the surface of the sloped roof and the counter flashing member is extending downward adjacent to the support overlapping the bent-up leaf member; and

(c) beginning construction of the masonry wall above the surface of the roof upon the fabricated support so that a section of the flashing is interposed between the fabricated support and the bottom of the masonry wall;

whereby the need for separately attaching counter flashing to the masonry wall for overlapping the bent-up leaf member is eliminated.

2. The improved method of claim 1 wherein the fabricated support is made of light-weight material.

3. The improved method of claim 2 wherein the fabricated support comprises a plurality of wood planks resting on edge with their planar surfaces facing one another.

4. The improved method of claim 3 wherein spacing means is employed between the planar surfaces of the planks so that the fabricated support is flush with the vertical framed wall of the building and the bent-up leaf member of the shingle-based flashing.

5. The improved method of claim 1 wherein the flashing is coated with a polymeric material except the counter flashing member.

6. The improved method of claim 1 wherein the masonry wall is constructed so that a cavity is formed behind the masonry wall for channeling water that seeped through the masonry wall downward with respect to the sloping roof.

7. The method of claim 1 wherein the counter flashing member has a lip indented inward at its lowest downward extension for sealingly engaging the bent-up leaf member of the shingle-based flashing.

8. An improved method of using flashing for weather proofing a building at the juncture of the edge of a sloped roof and a vertical wall, wherein the sloped deck of the roof is covered with shingles combined with a shingle-based flashing having a bent-up leaf member protruding above the roof surface for sealing the juncture, and the vertical framed wall is covered by a masonry wall and counter flashing is used to cover the bent-up leaf member of the shingle-based flashing to complete the sealing of the juncture, the improvement comprising the steps of:

(a) positioning a fabricated support at the juncture so that the support extends the length of the juncture and parallel to the slope of the roof and is flush with the bent-up leaf member of the shingle-based flashing and the vertical framed wall of the building;

(b) covering the fabricated support with a one-piece flashing so that the one-piece flashing is positioned entirely above the surface of the roof, the one-piece flashing being shaped like a step having an L-shaped member with a vertical planner section and a transverse planar section joined thereto by a first imperforate seam and extending laterally therefrom, and a counter-flashing member extending downwardly and generally perpendicularly from the transverse planar section and joined thereto by a second imperforate seam, so that the transverse planar section is securely resting atop the fabricated support and the vertical planar section is flush against the surface of the vertical framed wall, and the counter flashing member is extending downward adjacent to the support overlapping the bent-up leaf member of the shingle-based flashing; and

(c) constructing the masonry wall beginning above the roof surface so that the transverse planar section of the L-shaped member is interposed between the fabricated support and the bottom of the masonry wall;

whereby the need for separately attaching counter flashing to the masonry wall for overlapping the bent-up leaf member is eliminated.

9. The improved method of claim 8 wherein the fabricated support is made of light-weight material.

10. The improved method of claim 9 wherein the fabricated support comprises a plurality of wood planks resting on edge with their planar surfaces facing one another.

11. The improved method of claim 10 wherein spacing means is employed between the planar surfaces of the planks so that the fabricated support is flush with the vertical framed wall of the building and the bent-up leaf member of the shingle-based flashing.

12. The improved method of claim 8 wherein the L-shaped member is coated with a polymeric material prior to installation.

13. The improved method of claim 8 wherein the masonry wall is constructed so that a cavity is formed behind the masonry wall for channeling water that seeped through the masonry wall downward with respect to the sloping roof.

14. The method of claim 8 wherein the counter-flashing member has a lip indented inward at its lowest downward extension for sealingly engaging the bent-up leaf members of the shingle-based flashing.
