Flashing where roof meets brick wall.

Sidewall flashing a sidewall is a junction between a wall and a sloped portion of a roof. If the flashing is improperly installed or it is not present the wall roof. 1 run membrane down the side of the block and onto the roof underlayment. Flat roof and flashing against brick wall install base flashing under shingles or over metal roofing material.

Except where walls are brick the vertical part of the sidewall flashing should extend up behind the exterior wall covering just like with headwalls. The metal flashing is formed with a hook edge and cleated on 12 centers. The flashing extends up the wall at least 4. Flashing must be used where the foundation meets the brickwork.

The horizontal part of the flashing will vary depending on the type of roof covering material. It should extend from the brick veneer wythe through the brick s exterior face and end in a mortar joint in the interior wythe. 2 fold a vertical strip into the inside corner extending it above the top of the block so that the next layer of flashing will cover it shingle style. Flashing joints are lapped 6 in the direction of water flow.

The flashing extends onto the roof a minimum of 2 inches 4 inches is preferable in more severe climate areas. Follow the photo for illustrated instructions. 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.
