The average cost to replace a skylight is between $800 – $2,200.

When installed and maintained correctly, VELUX skylights are protected under warranty for up to 20 years and often last 30 years or longer before homeowners start to consider replacement. However, not all skylights are created equally, and sometimes the need to replace old, plastic, or lower-quality skylights with new glass VELUX skylights arises.

There are many factors that affect the price of replacing a skylight like the type of skylight, where the skylight is located on your roof, and how much damage (if any) it has incurred. In most cases, the price to replace a skylight will be cheaper than it initially was to get installed.

Type of Skylight Repair

Glass Replacement

Including labor, replacing the glass in your skylight will typically cost around $300 – $800. The price will vary depending on if the glass is double- or triple-paned.

If the glass is just cracked, it can often be repaired using silicone caulking and weather tape for around $300. These types of cracks typically come from weather damage such as hail or debris and are generally minor repairs. For repairs like this, we recommend reaching out to your skylight installer or contacting VELUX customer support so we can connect you with a skylight service professional in your area.

A larger piece of debris breaking one or more of the glass panes will be a more costly repair as it requires a professional to come out and replace the glass. In these cases, VELUX often recommends replacing the entire skylight as this will require fewer repairs in the long run, saving you time and money.

Skylight Motor Replacement

If you own a VELUX Electric Fresh Air Skylight or VELUX Solar Powered Fresh Air Skylight, replacing the motor of the skylight can cost between $110 and $510. Depending on the extent of the damage, an electrician may be needed to replace the wiring.

Whether you’re simply replacing the batteries or purchasing replacement parts, this type of repair can cost between $10 to $300.

Leaking Skylight

Whether your old skylight was poorly installed or has been damaged in some way, the flashing and sealing may need to be replaced or repaired if you’re experiencing leaks. This can cost between $300 and $800.

With new technology and more efficient installation methods, leaking skylights are much less of a problem than they used to be. In fact, VELUX has a patented method of three layers of protection installed as part of the flashing with each of our skylights to help them remain weathertight and stand strong against the elements.

Corridor Replacement

Although a less common repair, a skylights framing may need to be replaced. This repair costs between $170 and $600. Typically, the framing will last 20 – 40 years until the shell is corroded.

Other factors that affect the price of a skylight

There is a great deal of variability when determining the cost of how much your skylight replacement or repair will cost. Here are some other factors that go beyond labor and parts that can affect your bottom line.

Skylight Type

The type of skylight you need replaced or repaired plays a large role in determining the final cost.

Tubular skylights, like VELUX Sun Tunnel Skylights for example, are often the least expensive to replace as they are the easiest to install. They cost on average $300 – $500 to repair and can be replaced in half a day or less.

Depending on the type of repair, Fixed Skylights will cost between $400 – $900 to repair as they are larger and occupy more space on your roof.

Electric- or solar-powered skylights will be most expensive to fix at around $500 – $1200 because of the complexity of the installation and wiring. In some cases, an electrician may be required.

Your Roofer or Installer

Who you hire to replace your skylight will also affect the price. Typically, your roofer or installer will buy the replacement skylights or parts from VELUX through a dealer or a home improvement store (like Home Depot or Lowes), then the rate they charge for your repairs and installation will cover these costs. Roofers and installers will typically set their rates based on experience and availability of materials.

Insurance

If your skylight needs replacing due to normal wear and tear and is no longer under warranty, then typically it will have to come out of your budget. If you can prove that the damage is caused naturally or from bad weather, you can often get the repair covered through your homeowner’s insurance.

VELUX offers one of the strongest warranties in the business, with protection against installation defects for 10 years, glass protection for 20 years, and protection for controls and accessories for at 5 years. Learn more about VELUX warranty coverage here.
