Flashing & Scupper Systems

Flashing directs water away from roof penetrations, parapet walls, and edges, while scuppers give that water a clear path off the roof entirely. When either one fails, water finds the gaps in a roof system instead of moving past them. Chicago Flat Roofing Contractors inspects and repairs these details as part of keeping flat and low-slope roofs watertight through every season.

Common Trouble Spots

Loose or cracked flashing — seams around vents, walls, and edges that have separated or corroded.
Blocked or undersized scuppers — openings that can't keep pace with heavy rain or snowmelt.
Deteriorated parapet walls — masonry that lets water behind the flashing line.

How It Connects to Other Roof Work

Ice & Water Shield Membrane — added protection at edges and valleys most exposed to Chicago ice.
Tuckpointing & Mortar Systems — mortar repair that restores the parapet walls flashing depends on.
Photo-Documented Storm Damage Reports — clear records of flashing and scupper damage after a storm.
