Why is my flashing sagging

Roofing

The answer to 'why is my flashing sagging' is that the flashing has become loose or detached from the roof or wall. This is a common issue that can be caused by a few different factors, including poor installation, age and weathering, or physical damage.

Sagging flashing can allow water to seep into the roof system, leading to leaks and potential water damage. It's important to address this problem promptly to prevent further issues. The good news is that in many cases, sagging flashing can be repaired without needing to replace the entire roof.

    Apply a high-quality sealant or roofing caulk to fill any gaps and re-adhere the flashing to the roof or wall.
