Roof Scupper Drainage Troubleshooting Guide

Step-by-Step

1

Locate All Scuppers

Identify all scupper locations on your flat or low-slope roof. Scuppers are openings in parapet walls or roof edges that allow water drainage.

2

Check for Blockages

Inspect scuppers for debris, vegetation, or other blockages that restrict water flow. Even partial blockages can significantly reduce drainage capacity.

3

Assess Size and Placement

Evaluate whether scuppers are appropriately sized and placed for your roof area. Inadequate size or improper placement can lead to water pooling and roof overloading.

4

Inspect Collector Heads

If scuppers connect to downspouts via collector heads, check these components for proper attachment, sealing, and function. Look for leaks or overflow during rainfall.

5

Examine Adjacent Roofing

Check roofing material around scuppers for signs of ponding water, membrane damage, or deterioration that might indicate drainage problems.

⚠️ Safety Warning

Scupper problems on commercial or flat roofs can lead to catastrophic roof failure due to water weight. Modifying scupper systems requires understanding complex drainage calculations and building code requirements. Professional commercial roofers can properly assess drainage needs and ensure scupper systems meet local code requirements for emergency overflow provisions.
