Skylights can brighten your home with natural light and enhance energy efficiency, but they don’t last forever. Knowing when to replace your skylight depends on several signs of wear, damage, or inefficiency. Here are key indicators to watch for:
1. Leaks or Water Damage
One of the most common signs that a skylight needs replacing is water leakage. If you notice water stains on the ceiling around the skylight, or if you see actual dripping during rain, this is a sign that the seal has failed and water is getting in.
2. Condensation Between Layers of Glass
If your skylight is a double-glazed unit, condensation between the layers of glass is a clear indication of seal failure. This means the insulating gas or air between the panes is no longer intact, leading to heat loss and reduced energy efficiency.
3. Cloudy or Yellowed Glass
Over time, exposure to UV rays can cause the skylight’s glazing material to degrade, leading to cloudiness, yellowing, or a foggy appearance. This reduces the natural light entering your space and may signal that the skylight needs replacement.
4. Damage to the Frame
Inspect the skylight frame—whether it’s wood, metal, or plastic. Cracks, rot (in wooden frames), or rust (in metal frames) can compromise the skylight’s structural integrity. If the frame is badly damaged, replacing the entire skylight may be more cost-effective.
5. Difficulty Opening or Closing (For Vented Skylights)
If you have a vented skylight that is stuck or difficult to open or close, it could be a sign of mechanical failure or wear on the moving parts. If repairs aren’t effective, replacement might be necessary.
6. Increased Energy Bills
Old or damaged skylights often lack proper insulation, allowing heat or air conditioning to escape. Gaps or poorly insulated frames can significantly increase energy costs. Replacing your skylight with a more energy-efficient model can reduce utility bills.
7. Visible Cracks or Physical Damage
Inspect the skylight for any cracks, chips, or other visible damage in the glazing or frame. Even small cracks can lead to water penetration, while larger cracks may compromise the skylight’s structural integrity entirely.
8. Deterioration of the Flashing
The flashing around the skylight directs water away to keep the installation waterproof. Over time, flashing can corrode or shift out of place. Damaged or missing flashing can lead to leaks and signal the need for a full replacement.
9. Age of the Skylight
Skylights typically last around 15-20 years, depending on the material and maintenance. If your skylight is nearing or past its lifespan, replacing it is recommended, even if no significant issues are visible.
10. Noisy During Weather Changes
If your skylight makes unusual noises, like creaking or whistling during windstorms or temperature changes, the seals or framing may be compromised, indicating it’s no longer performing properly.
If you notice any of these issues, it’s a good idea to consult a professional installer to replace your skylight. At Ferreira Exteriors, we specialize in skylight assessments, repairs, and replacements. Visit us at ferreiraexteriors.com for expert advice and quality service.
