Where should visible wall covering transition flashing be installed?

Visible wall covering transition flashing is crucial in preventing water intrusion where different wall covering materials meet. This type of flashing serves as a barrier that directs water away from the building envelope, minimizing the risk of leaks and moisture-related damage.

When two different materials are joined, there can be gaps or potential points of failure where water might seep through. Transition flashing is specifically designed to manage these junctions, ensuring that any water that accumulates is diverted away from the wall assembly instead of being trapped between the materials. Thus, proper installation of transition flashing at these points is essential for maintaining the integrity and longevity of the structure.

The other scenarios mentioned – corners of the building, the base of the building, and where roofs meet walls – involve other types of flashing that serve different purposes. While these areas also require proper flashing techniques to manage water drainage, they do not specifically address the transition between differing wall covering materials as effectively as transition flashing does. Hence, focusing on where different wall coverings interface is critical for optimal waterproofing.
