Flashing As Siding

Install the water resistant barrier to overlap the top edge of the weep screed.

Flashing as siding.

Position the flashing lengths as defined in step 2 overlapping the ends a minimum of 2 inches onto the previous flashing piece and securing the flashing with 8d nails at each wall stud. Flashing is a strip of metal usually aluminum about 8 inches long and bent at 90 degrees with each side at least 5 inches wide. On a wall to be covered with wood cement board vinyl or metal. With the flashing in place let s see what happens.

Even if the roof has been properly flashed against the sidewall this one hasn t water can still run down the side of the house and behind the siding causing rot. The water then runs off the flashing because it can t go up the flashing as it extends up behind the siding. Siding is the first line of defense against water intrusion and the multitude of problems it causes including the dreaded mold. Use a felt paper spline wrapped around the corner and extending 6 inches beyond the corner board to protect the joints where the siding meets the corner boards see figure 1 5 at left.

The water runs down the siding and at the bottom of the first row of vinyl siding it drips off and contacts the metal flashing as it runs across the top of the fascia board. But many builders fail to protect the most vulnerable areas of siding. This has proven problematic over time as caulking the joint results in unsightly surface appearances due to the different textures as well as resulted. A common problem with cement board siding products and some other types of horizontal lap siding is that older installation guidelines called for caulking the joint instead of flashing the joint.

Continue installing the z flashing at the top edge of the siding panels across the full length of wall. Install the lathe and stucco to the first bend in the weep screed.
