Under what condition are metal flashings not allowed to be reinstalled?

Metal flashings are critical components in building construction, as they direct water away from vulnerable areas such as joints and intersections. When flashings are rusted, damaged, or deteriorated, their ability to effectively manage water is compromised. This failure not only leads to potential leaks but can also result in water damage to both the roofing and the underlying structure. Therefore, the reinstallation of metal flashings in such a compromised condition is not permitted, as it does not meet safety and functionality standards established in the North Carolina Residential Code.

In contrast, conditions like being outdated or painted do not inherently affect a flashing's structural integrity or performance. Even if flashings are old, as long as they are still intact and functional, they may still be suitable for continued use. Thus, the emphasis is on the physical condition of the flashings—specifically looking for signs of physical deterioration—when determining whether they can be reinstalled.
