Are solar tubes more likely to leak than skylights?

Solar tubes are not more likely to leak than skylights when installed correctly. Both systems require proper flashing and sealing. Because solar tubes are smaller, they often present fewer integration challenges. Most leak issues are related to installation quality rather than the type of daylighting system.

Can heavy rain cause a solar tube to leak?

Heavy or wind-driven rain can expose weaknesses if flashing or sealing was done incorrectly. A properly installed solar tube should handle rain without issues. If moisture appears after storms, a roof inspection can help identify the source.

How long should a properly installed solar tube last without leaking?

A well-installed solar tube can last for many years without leaking. Often, the surrounding roofing materials will age before the solar tube itself becomes a problem. Regular roof inspections help address small issues before leaks develop.

Is moisture around a solar tube always a leak?

No. Moisture around a solar tube is often caused by condensation rather than water entering from outside. This can occur in humid spaces like bathrooms or during cooler months. A professional inspection can determine whether the issue is condensation or an actual leak.

Should a leaking solar tube be repaired or replaced?

That depends on the cause of the issue. Many solar tube leaks can be resolved by repairing flashing or sealing around the tube. Replacement is typically only necessary if the tube or dome is damaged or if the surrounding roofing system has significant wear.
