Next you will use asphalt or roofing cement.

Roof flashing against stucco wall.

Add cement and flashing. The flashing extends onto the roof a minimum of 2 inches 4 inches is preferable in more severe climate areas. Flash onto the surface of the existing stucco. Lay 2x4 blocks on the roof to set a consistent height for the weep screed flashing.

Installing step flashing to stucco walls step 1. Installing the roofing felt. Once the flexible flashing is set i apply a piece of housewrap along the wall where the fascia meets it. Typically made of aluminium or galvanized steel flashing is any material used over joints in your walls or roof to prevent water from seeping through.

Wrap the top of the wall with the wrb and install a new cap flashing. Above the roof sheathing. For step flashing with a stucco wall you will be working in part on the roof. The roof flashing cannot be installed on the outside of the stucco and counter flashed.

Alternatively if allowed install painted metal wall panels from roof flashing up and under existing cap flashing. Then install new stucco over the existing including a wrb. I use a wide piece of flexible flashing tape to protect the area between the subfascia and the wall. Applying flashing to a stucco roof or walls requires both cement and nails as well as caulk or more stucco to create a water tight seal.

Slip the wall leg of the weep screed behind the existing paper. I cut the tape so that it laps onto the housewrap above and 3 in. Flexible flashing tape seals the eave to the wall. The water that does penetrate behind the stucco will then be trapped there or worse forced down the inside of the walls and ceilings possibly causing damage and mold.

The flashing extends up the wall at least 4. The metal flashing is formed with a hook edge and cleated on 12 centers.
