Lesson learned:
Exterior sealant/caulk is often used in construction, but its eventual failure must be assumed. Flashing is a critical last line of defense within building enclosure walls and roofs that provides leak protection from the forces of wind, water, temperature changes, and ice. Installing flashing after a building has already been constructed requires at least a portion of the exterior enclosure be disassembled and rebuilt. If left out or constructed improperly…get the buckets ready!
I look forward to a return visit after the ambitious USAF Academy Chapel renovation is complete…
