Oh no! A leak.


You've just noticed a dreaded drip from your skylight. But wait, before you panic, let's consider that it might not necessarily be a leak. Especially if it's cold outside, there's a possibility that what you're experiencing is condensation.


Think about that cold can of pop you take out of the fridge on a hot day. After a few minutes, moisture starts to collect on the outside of the can. That's condensation in action. The same principle applies to your windows and skylight. When the relative humidity in the air is too high for the outdoor temperature, condensation forms.


So, first things first, check the humidity levels in your space. If it's higher than the recommended amount, consider using a dehumidifier to reduce the moisture in the air. If your humidity is within range or if the drip persists even after using a dehumidifier, then it's time to have your skylight looked at by a professional.

Outdoor Temperature Range Indoor Humidity Should Not Exceed
20-40° F 40%
10-20° F 35%
0-10° F 30%
-10-0° F 25%
-20- -10° F 20%
Below -20° F 15%
