5 Signs Your Skylight Needs Resealing – Before It Becomes a Problem
5 Signs Your Skylight Needs Resealing – Before It Becomes a Problem
When it comes to maintaining your commercial skylights, prevention is always more cost-effective than emergency repairs. Skylights are common leak entry points, especially on flat commercial roofs throughout North and Central New Jersey. At 1Call Restore, we’ve seen firsthand how a simple reseal can extend the life of your skylight by years—if you catch the problem early.
Here are five signs that your skylight might need professional resealing before it turns into a bigger issue:
1. Visible Cracks or Gaps in the Sealant
Take a close look around the edges of the skylight. If you notice cracking, bubbling, or separation in the sealant, water can easily seep in. Even hairline gaps are a red flag, especially after harsh weather.
2. Interior Water Stains Around the Skylight
Brown stains, bubbling paint, or ceiling discoloration near your skylight? These are common signs that moisture is getting in through worn or failed seals—not necessarily the skylight itself.
3. Drafts or Temperature Fluctuations
If your commercial space feels drafty under the skylight, it may not be properly sealed. This can affect energy efficiency, increase HVAC costs, and signal that air (and water) is entering where it shouldn’t.
4. Mold or Mildew Growth
Mold near skylights is often the result of long-term moisture intrusion. By the time it’s visible, the seal has likely been compromised for a while. Addressing the seal now can prevent major remediation later.
5. Debris or Water Pooling Around the Skylight
Flat roofs are prone to drainage issues. If you see pooling around the skylight curb or blocked drainage nearby, that standing water could be slowly breaking down your seals. It’s a sign your skylight—and gutters—need attention.
