Rain vs condensation
Active dripping during rain points to flashing, curb, or surrounding shingle integration.
Winter fog or frost on the interior glass with no rain often means warm moist air hitting cold glass — ventilation and humidity control matter too.
Common failure points
- Dried or cracked sealant relied on instead of proper step flashing
- Curb rotted from years of slow leaks
- Skylight installed on a low slope without a cricket
- Roof replacement that reused old curb flashing
Repair or replace
Newer units with sound curbs may get re-flashed during a roof job. Older acrylic bubbles or cracked domes are often replaced as a unit.
We coordinate skylight scope with the roof tear-off so you are not paying for two mobilizations.
