You’re planning a roof replacement, and then you look up at your skylights and wonder… do those need to be replaced too?
It’s a common question, and ignoring it can lead to leaks, extra costs, or having to redo part of your new roof later. If you’re asking should you replace skylights when replacing roof, the answer depends on age, condition, and how your new roofing system is being installed.
Should You Replace Skylights When Replacing Roof? Quick Answer
In many cases, yes, you should replace skylights when replacing your roof, especially if they are older or show signs of wear. Skylights and roofing systems work together, and replacing the roof without updating aging skylights can increase the risk of leaks.
As we often explain to homeowners, if your skylights are more than 10–15 years old, replacing them during a roof replacement is usually the smarter and more cost-effective choice.
Why Skylights Matter During a Roof Replacement
Skylights are not just add-ons. They are integrated into your roofing system.
They penetrate the roof system
Any opening in your roof creates a potential weak point. Skylights rely on proper flashing and sealing to stay watertight.
They depend on surrounding materials
When a new roof is installed, the surrounding materials change. Old skylights may not align well with new flashing systems.
This is why skylights often become problem areas after roof replacements if not addressed properly.
When You Should Replace Skylights
Not every skylight needs to be replaced, but these situations strongly suggest it.
1. Skylight is over 10–15 years old
Most skylights don’t last as long as a roof. Even if they look fine, seals and flashing may be near failure.
2. You’ve had leaks or moisture issues
Signs include:
- water stains around the skylight
- condensation between glass panes
- bubbling drywall
If leaks have occurred before, replacement is usually the safest option.
3. The flashing is outdated or damaged
Flashing is what keeps water out. If it’s worn or incompatible with the new roof system, it becomes a risk.
A proper roof inspection can confirm whether flashing is still reliable.
4. You’re upgrading your roof system
New roofing materials often work better with updated skylight systems.
For example, switching materials may require different flashing kits or installation methods.
When You Might Keep Existing Skylights
In some cases, keeping skylights makes sense.
Conditions where keeping them is okay
- skylight is relatively new (under 10 years)
- no leaks or visible damage
- flashing system is compatible with new roof
Even then, resealing or flashing updates may still be recommended.
Cost Comparison: Replace Now vs Replace Later
This is where many homeowners make the wrong call.
| Option | Cost Impact | Risk Level |
| Replace during roof replacement | Lower overall cost | Low |
| Replace later | Higher (labor + roof disruption) | Higher |
Takeaway: Replacing skylights during a roof project avoids future labor costs and prevents disturbing your new roof.
What Happens If You Don’t Replace Skylights?
Skipping replacement can create problems down the line.
Common risks
- leaks around skylight edges
- failed seals after new roof installation
- need to remove roofing sections later
In Florida, with heavy rain and humidity, these issues can appear faster than expected.
For storm-related concerns, see what to do after hail, wind, or rain damage.

Modern Skylights vs Older Skylights
New skylights offer better performance.
Improvements in newer models
- better insulation
- improved sealing systems
- stronger leak protection

Upgrading during roof replacement can improve comfort and reduce long-term maintenance.
Florida-Specific Considerations
Orlando weather makes skylight decisions more important.
Heavy rain exposure
Skylights must handle consistent rain without leaking.
Humidity impact
Moisture buildup can affect seals and interior finishes.
Storm resistance
High winds can stress flashing and mounting points.
In this climate, replacing older skylights during roof work is often the safer option.
