Why is My Chicago Flat Roof Leaking Near Penetrations?

If you're noticing water stains on your ceiling or walls, especially near pipes, vents, or other elements that penetrate your flat roof in Chicago, it's a clear sign of trouble. These "penetrations" are inherently vulnerable spots on any roof, and on a flat roof, they can become significant leak sources if not properly sealed and maintained.

Leaks around penetrations typically occur when:

Cracks or gaps form: Over time, exposure to Chicago's extreme weather (freeze-thaw cycles, intense sun, high winds) can cause the sealant or flashing around the base of these pipes, vents, or other equipment to crack, dry out, or pull away.

Material deterioration: The original seals might simply be deteriorating due to age, leading to small openings that allow water to seep through.

Improper installation: If the penetrations weren't properly flashed and sealed during initial installation, they can be a chronic source of leaks.

Even small openings can allow substantial amounts of water to enter your building, leading to costly damage to insulation, the roof deck, and your interior.
