Best Practices for Mitigating Roof Leaks After Heavy Snow on School Roofs

The recent heavy snowfall and extreme cold across Kentucky and the US have blanketed schools with significant accumulation, setting the stage for leaks as thawing occurs. Ice dams—where snow melts on warmer roof sections and refreezes at colder edges—and blocked drainage are the main threats, especially on flat/low-slope roofs common in educational buildings. These can cause water intrusion into classrooms, hallways, and critical athletic spaces like basketball gyms.

Follow these best practices to minimize leaks during and after melt-off:

1. Clear Snow and Ice from Roof Drains and Scuppers

Buried or iced-over interior drains and scuppers prevent proper runoff, leading to ponding and interior leaks. As conditions allow, safely remove snow/ice from around these areas using roof-safe tools or professional help to avoid damaging the membrane.

 

2. Maintain Clear Gutters and Downspouts

Debris-filled or ice-blocked gutters cause backups that force meltwater under edges or create ice dams. Inspect and clear them pre-storm and during thaw. In prone areas, heat cables can help keep flow open and reduce dam risks.

3. Manage Ice Dams Effectively 

Extreme cold exacerbates dams by keeping roof edges frozen while interior heat melts snow above. For gyms and large open spaces with potential heat loss, this is a common issue. Safely rake excess snow from edges (with appropriate tools) to lessen weight and water volume. Long-term, improve insulation and ventilation for even roof temperatures.

4. Watch for Warning Signs

Monitor for ceiling stains, drips, or wet walls—especially in high-use areas like gyms—during early thaw. Early detection avoids bigger damage and closures.

5. Arrange Professional Roof Assessments 

Post-event inspections by qualified roofers identify hidden issues like overloaded sections or drainage failures before leaks escalate. For schools, quick action keeps facilities functional.

Focusing on drainage and ice control now can prevent major water damage and costly repairs. If issues arise, contact a trusted local partner like Woodall Roofing & Exteriors for expert support.
