- Causes include differential thermal movement between wall and counterflashing receiver, poor original installation, or lack of maintenance, for instance, counterflashing that is not reattached when it becomes loose. Repair procedure is: · hud.gov
- Integral wall counterflashings are set into a reglet joint that is cut into the wall, masonry, stucco or metal, and uses the groove to secure the metal within the wall assembly. These types of attachments provide long-term weatherproofing performance because the counterflashing is sealed within the joint. Sealant may be applied at the top of the counterflashing in some cases. However, unlike the surface-mounted application, the sealant is the secondary line of defense and may not be recommended. · jm.com
