If you’ve looked out the window lately, you’ve probably noticed it feels like it has rained every other day. While all that moisture may be frustrating for outdoor activities, it can actually provide valuable insight into the condition of your commercial roof.
Rain has a way of exposing roofing problems that might otherwise go unnoticed. Small leaks, drainage issues, clogged gutters, and vulnerable flashing often make themselves known during periods of frequent rainfall. The challenge is that what starts as a minor issue today can become a much bigger problem once winter arrives.
For commercial building owners and facility managers, fall is the ideal time to identify roofing concerns and address them before freezing temperatures, snow, and ice put additional stress on the system.
Why Rainy Weather Is the Perfect Roof Test
Your roof’s primary job is to keep water out. When rainfall becomes frequent, your roofing system is put to the test.
Pay attention to signs such as:
- Water stains on ceilings or walls
- Dripping around rooftop penetrations
- Overflowing gutters during moderate rain
- Standing water that remains long after a storm
- Damp insulation or unusual humidity inside the building
These issues may seem manageable during the fall, but they can become significantly more expensive when temperatures drop below freezing.
The good news is that rain often reveals these problems while there’s still time to fix them.
Small Problems Become Big Problems in Winter
One of the most damaging winter conditions for commercial roofs is the freeze-thaw cycle.
Here’s how it works:
Water enters a small crack, seam, or opening in the roofing system. When temperatures drop, that water freezes and expands. As it expands, it widens the opening and creates more damage. When temperatures rise again, more water enters the newly enlarged gap. The cycle repeats over and over throughout the winter.
What began as a small maintenance issue can quickly develop into:
- Active roof leaks
- Damaged insulation
- Interior water damage
- Mold growth
- Structural deterioration
- Emergency repair costs
This is why addressing drainage and moisture issues before winter is one of the smartest investments a building owner can make.
Five Areas Every Facility Manager Should Check Before the First Freeze
1. Gutters and Downspouts
Leaves, twigs, and debris often accumulate throughout the fall season.
When gutters become clogged, water cannot properly drain from the roof. During winter, trapped water freezes and creates ice buildup that can damage both the roof edge and gutter system.
Make sure gutters and downspouts are clean, secure, and directing water away from the building.
2. Roof Drains and Scuppers
Commercial roofs rely heavily on proper drainage.
Blocked roof drains can cause water to pond for extended periods, adding unnecessary weight and accelerating roof deterioration.
If your roof has internal drains, scuppers, or overflow systems, now is the time to inspect and clean them.
3. Areas with Ponding Water
After a storm, water should move off the roof within a reasonable amount of time.
If puddles remain for more than 48 hours, that could indicate drainage issues, insulation problems, or structural concerns.
Ponding water is never something to ignore. Once winter arrives, those same areas can freeze and place additional stress on the roofing system.
4. Flashing and Roof Penetrations
Many roofing leaks don’t occur in the field of the roof itself. Instead, they occur around penetrations such as:
- HVAC equipment
- Pipes
- Skylights
- Vents
- Curbs
- Roof hatches
Flashing around these areas expands and contracts throughout the year. Over time, sealants can crack and gaps can develop.
Frequent rain can help identify vulnerable areas before winter weather makes repairs more difficult.
5. Roof Seams and Membranes
TPO, PVC, EPDM, and modified bitumen roofing systems all rely on properly sealed seams to remain watertight.
As roofing systems age, seams can loosen or separate.
A professional roof inspection can identify these early warning signs so repairs can be completed before snow, ice, and freezing temperatures arrive.
Don’t Wait for the First Snowstorm
Many building owners don’t think about their roof until a leak develops.
Unfortunately, emergency roofing repairs are often more disruptive, more expensive, and more difficult to complete during winter weather.
A proactive inspection during the fall allows you to:
- Identify hidden storm damage
- Improve drainage performance
- Address minor repairs before they worsen
- Reduce the likelihood of emergency service calls
- Extend the life of your roofing system
Most importantly, it provides peace of mind knowing your building is prepared for whatever winter brings.
