How Long Do Skylights Last?

Skylights will last an average of 8-15 years, according to Plasteco. The life expectancy of the skylights will either increase or decrease depending on the quality of the light itself and installation.

How To Maximize A Skylight’s Life Expectancy

Here are a couple of the best possible ways to maximize your skylight’s lifespan:

Proper Skylight Positioning

Ideally, a skylight should produce/allow a sufficient amount of sunlight through its transparent panes. When you place the skylight in the best possible spot in your home, it will enhance the area’s illumination. Put the skylight in a position where it can maximize light reception during the installation process. If you are looking for the most light possible to enter the home, position the skylight facing south. Of course, a north facing skylight offers more of a softer lighting within the home.

Routine Maintenance

Throughout its life, a skylight will require some maintenance needs. While a daily or weekly cleaning is not necessary, it’s vital to watch for any signs of damage to the skylight. Routine maintenance simply means cleaning both sides of the light. Perform any maintenance tasks whenever you notice leaks or cracks in the lighting. A lack of maintenance is one of the biggest factors preventing a long and healthy life for your skylight. Contact the professionals for any and all maintenance needs today!

What Causes Damage To Skylights?

A few things can cause damage to your skylights. These factors include:

Faulty Repairs

Avoid any mistakes by choosing professional services for any repair needs. Leaks or cracks will require professional care.

Poor Installation

This is the number one reason why a skylight’s life expectancy will decrease. Poor installations will ultimately lead to cracks and leaks. If the skylight is not in the best spot in the home or sealed improperly, this can cause numerous issues.

When Should You Replace A Skylight?

Here are a few signs that your skylight needs to be replaced:

Cracks On Panes

The most obvious sign that you need a replacement is whenever you notice any cracks on the panes. Cracks will allow heat and water into the home. While the cracks will generally start small, the gaps can increase quickly over time. Not only will this reduce the skylight efficiency, it will also increase your heating costs.


Leaks can be the worst possible problem facing your skylight. Remember, a skylight is just like a window – it’s part of your roofing. When leaks persist, this can cause damage to the surrounding areas, and create mold and mildew.


Skylights can become discolored over the years. Any yellowing will prevent sufficient light from entering the home. Furthermore, you may also notice some peeling or bubbling forming on the drywall surrounding the skylight at this time. Any time that the skylight fails to do its job at the highest level, a replacement is recommended.
