Hidden Damage With the sheathing removed, we can see any additional water damage that we missed during the initial search. On this house, the south wall (which faced the street) was in worse shape than we thought. The whole wall was rotted and had to be reframed, reinsulated, and resheathed, and all of the windows and doors had to be replaced (Figure 5).

Figure 5. Hidden damage to the structure was discovered during tear-off on the south wall. The wall had to be torn out and replaced, including wiring and insulation (left), and doors and windows (right). The source of the leak appeared to be missing copper kick-out flashings at roof/sidewall junctions, which we installed (Figure 6).

Figure 6. Missing kick-out flashings at roof-wall junctions are a common source of leaks in EIFS failures. The author prefers a heavy-gauge copper for these flashings. Once the house is opened up, the engineer and the city inspectors may also discover code violations, like missing flashing or building paper. All of these items have to be brought back to code before the framing inspection, as if it were a new home.
