Question: A homeowner has reported water leakage around an exterior door frame. A carpenter inspects the installation and finds that the head flashing was installed underneath the WRB at the top of the door. What remediation step is most critical to prevent future leaks?
Answer options:
- Apply a bead of caulk along the top edge of the head flashing.
- Ensure the head flashing extends past the jambs by at least 25 mm on each side. ✅ Remove the existing head flashing and re-install it over the WRB, ensuring proper shingling.
- Install a wider piece of trim around the door to cover the existing flashing.
Correct answer: Remove the existing head flashing and re-install it over the WRB, ensuring proper shingling.
Explanation: Head flashing must be installed OVER the weather-resistive barrier (WRB) to shed water away from the door opening and allow the WRB to drain over the flashing. Installing it underneath traps water behind the WRB. Proper re-installation ensuring shingling from top to bottom is crucial.
