Here's a conversation on this topic!

Skylights are a beautiful feature that bring natural light into your home, but when they start to fail, they can quickly turn into a costly problem. At Affordable Roofing, we often see homeowners unsure whether their skylight just needs a repair or a full replacement.

So how do you know when it’s time?


1. You Notice Water Leaks or Stains

One of the most obvious signs is water intrusion. If you see stains forming around your skylight or dripping during rain, it’s likely that the flashing or seals have failed. While minor issues can sometimes be repaired, recurring leaks usually mean it’s time for a replacement.

2. Fogging or Condensation Between Glass

If your skylight looks cloudy or has moisture trapped between the panes, the seal has broken. This reduces energy efficiency and visibility, and unfortunately, it’s not something you can fix without replacing the unit.


3. Drafts or Poor Insulation

Feeling cold air in the winter or heat in the summer? Older skylights often lack modern insulation. Replacing them with energy-efficient models can help lower your utility bills and improve indoor comfort.

4. Cracks, Discoloration, or Visible Damage

Over time, skylights can crack, warp, or become discolored due to UV exposure and weather conditions in Aurora, IL and the greater Chicagoland area. Damaged skylights not only look bad but can also compromise your roof’s integrity.


5. Your Skylight Is 15–20 Years Old

Even if there are no visible issues, age matters. Most skylights have a lifespan of about 15–20 years. If your roof is being replaced, it’s often more cost-effective to replace the skylights at the same time.

Why Replace Instead of Repair?

While repairs may seem cheaper upfront, they can add up over time. A new skylight provides:

  • Better energy efficiency
  • Improved leak protection
  • Enhanced natural lighting
  • Increased home value


At Affordable Roofing, we install high-quality skylights with proper underlayment and flashing to ensure long-term performance.


If your skylight is leaking, foggy, drafty, or simply old, it may be time to consider a replacement. Acting early can save you from more expensive structural damage down the road.
