We get the call every spring: "Water's dripping from my skylight after the rain." In Dallas, skylight leaks are the #1 non-storm roof repair we handle. Here's why they fail and what to do.
Why Skylights Leak (The 4 Most Common Causes)
- Failed flashing: The step flashing and counter-flashing around the curb is the first line of defense. Georgia's freeze-thaw cycles crack sealant, and wind-driven rain finds the gaps.
- Condensation (not a leak): In humid Georgia summers, warm moist air hits the cold glass — looks like a leak, but it's interior condensation. Proper ventilation and insulated glazing fix this.
- Cracked or yellowed dome: Older acrylic domes (pre-2005) become brittle. Hail cracks them; UV yellows them. Water follows the cracks.
- Improper installation: No ice & water shield under the curb, shingles not woven into step flashing, curb too low (< 4"). We see this on 40% of skylights we inspect.
Repair vs. Replace: The Decision Matrix
| Repair | Replace | |
|---|---|---|
| Flashing only | ✅ $300–$600 | Overkill |
| Cracked dome, frame OK | ✅ $400–$800 (dome swap) | Optional |
| Rotted curb / frame | ❌ Band-aid | ✅ $1,200–$2,500 |
| 20+ years old | ❌ Recurring | ✅ Modern glazing |
| Multiple past repairs | ❌ Diminishing returns | ✅ Fresh warranty |
What a Proper Skylight Replacement Includes
We don't just swap the unit. A full replacement means:
- Tear off shingles 3 ft around the curb
- Remove old curb, inspect deck for rot
- Build new pressure-treated curb (min 8" above roof deck per code)
- Ice & water shield full wrap + step flashing woven into each shingle course
- VELUX or Fakro unit — Low-E3 argon-filled, laminated glass, 20-year glass warranty
- Re-shingle with architectural shingles to match
Insurance: Does It Cover Skylight Leaks?
If a covered peril (hail, wind, fallen tree) damaged the skylight — yes. If it's age/wear/poor install — no. We document the cause with photos and a written report for your adjuster.
Prevention: Annual Skylight Checklist
- Inspect flashing sealant every spring — re-caulk with polyurethane (not silicone)
- Clear debris from the curb corners — leaves hold moisture
- Check interior for condensation stains — add a vent fan if needed
- After hail: have a roofer inspect the glass for micro-cracks
