Flashing where roof meets brick wall.

Flashing will need to be used at the base the intersection of the chimney with the rood and at the chimney crown. At the bottom of the roof water needs to be directed. It should extend from the brick veneer wythe through the brick s exterior face and end in a mortar joint in the interior wythe. Flashing must be used where the foundation meets the brickwork.

The flashing extends onto the roof a minimum of 2 inches 4 inches is preferable in more severe climate areas. The horizontal part of the flashing will vary depending on the type of roof covering material. The flashing extends up the wall at least 4. Keep doing this until you run out of stepped blocks.

1 run membrane down the side of the block and onto the roof underlayment. If the roof runs flat up against the brick wall you must install the roof side of the flashing either under the last layer of shingles or over the roof material if it is metal. Flat roof and flashing against brick wall install base flashing under shingles or over metal roofing material. Kickout flashing keeps water out of walls rain should run off the roof and into the gutter.

Except where walls are brick the vertical part of the sidewall flashing should extend up behind the exterior wall covering just like with headwalls. Step flashing protects the gap where roofs meet walls by weaving into the roof shingles. I cut the tape so that it laps onto the housewrap above and 3 in. Sidewall flashing a sidewall is a junction between a wall and a sloped portion of a roof.

Extend step flashing at least 4 inches up the wall from the roof deck and at least four inches out along the roof deck irc 2015 and integrate the flashing with the drainage plane above for example overlap house wrap over it.

Flexible flashing tape seals the eave to the wall. The metal flashing is formed with a hook edge and cleated on 12 centers. If the flashing is improperly installed or it is not present the wall roof. Step flashing is best for where the roof face meets a wall for example where a dormer projects out of the roof.

And 3 cap the block with membrane overlapping the first two pieces and bridging the gap between the block and the wall sheathing. In this spot it s possible that water could flow down the wall and slip past the shingles into the building below. Flashing joints are lapped 6 in the direction of water flow. Install corrosion resistant flashing pieces that are overlapped shingle fashion.
