Drain Clearing & Repair

Flat roofs depend on clear, working drains to move water off the surface before it pools or backs up under the membrane. Leaves, granules, ice, and general debris can block roof drains and scuppers over time, and once that happens, water has nowhere to go but sideways or down. Chicago Flat Roofing Contractors clears blocked drainage lines and repairs the components around them so water keeps moving the way it's supposed to.

What This Service Covers

Drain and Scupper Clearing — Removing debris, sediment, and build-up from roof drains and scuppers so water flows freely off the roof surface.
Flashing & Scupper Systems — Sealing and repairing the flashing and scupper components that channel water off the roof edge instead of letting it collect there.
Ponding Water Correction — Addressing the low spots and slope issues that keep water sitting near drains long after a rain or snowmelt.

Finding the Problem First

Drone Roof Inspections — Aerial passes over the roof surface locate blocked drains, damaged scuppers, and pooling areas without extra foot traffic.
Infrared Roof Moisture Scanning — Scanning beneath the membrane can reveal moisture that's already worked its way in around a slow or clogged drain.

When to Call

Standing water near a drain, slow runoff after rain, or damp ceiling stains below a roof drain line are all signs worth a look. Left alone, a blocked drain puts steady pressure on the membrane and the structure underneath it.
