Skylight Condensation vs. Roof Leak: How to Tell the Difference
To tell whether your skylight has a condensation problem or an actual roof leak, check the moisture pattern: condensation appears as uniform dampness across the glass or frame, often with frost on nearby nail tips during cold weather, and is caused by poor attic ventilation. A roof leak produces water that trails from a specific entry point — you’ll see streaks along rafters leading to the skylight flashing or frame seal. Condensation requires a ventilation fix; a leak requires a roofing repair. This guide walks through the diagnostic process step by step so you can identify the issue accurately and avoid unnecessary repairs.
