Why Is My Flat Roof’s Wall Flashing Coming Loose?
February 12, 2026
If you’ve noticed loose wall flashing on your flat roof, you’re not alone. This is a common issue for many homeowners in Chicago, especially given our city’s harsh weather conditions. Loose flashing can lead to water intrusion, damage to the roof deck, and costly repairs if not addressed promptly.
Why Wall Flashing Comes Loose
Flat roof wall flashing can loosen for several reasons:
Weather Exposure: Heavy rain, wind, and fluctuating temperatures can cause flashing to pull away over time.
Poor Installation: Improper fastening or sealing during the initial installation can result in gaps.
Aging Materials: Over time, roofing materials like modified bitumen or rubber membranes can shrink or deteriorate.
