In most cases, installing skylights will add to the value of your home, as buyers tend to like the appearance of these windows and prefer houses that let in natural light. However, savvy home buyers who know there are water damage risks with improperly installed skylights will want information on who installed the feature and when. If you can point to a professional skylight installer with experience, then the skylight is more likely to provide a better return on investment.

While it’s possible to install a skylight yourself, we don’t recommend it. DIY window installations are far more likely to leak due to improper placement technique. Making even minor mistakes could lead to thousands of dollars in water damage, meaning hiring a local skylight installer from the start would be more affordable. Plus, working on the roof is dangerous, as is maneuvering heavy, bulky windows up and into place. Even if you’re an experienced DIYer, we strongly recommend hiring a pro to install a skylight.

Skylights are the most likely windows to leak if installed improperly, so there are a few questions you should ask any skylight installer before you hire them:

• Do you specialize in skylight installation or only windows in general?

• Do you offer any kind of warranty for the installation?

• What recourse do I have if the skylight leaks shortly after installation?

• Do you have references I can speak with?

• How long have you been in business?

• Are you licensed and insured?

The average cost to install a skylight is about $1,850, and most homeowners pay between $450 to $5,000 each. Your total price tag will depend on many factors, including the type of roof material, the pitch of your roof, ease of accessibility, the skylight size, and the type of frame and glass you want. You can potentially lower your price if you install multiple windows or skylights simultaneously. Remember to budget $500 to $2,500 for labor costs to complete this project.

Skylights might sometimes increase your homeowners insurance premium, but the increase is usually minimal. Some home insurance companies won’t adjust your premium with the addition of a skylight, so you can contact your insurer or your professional skylight installer to ask about any expected changes. It’s crucial to have an expert install the skylight, as insurance companies may not insure your roof or cover water damage that results from a non-professional skylight installation.
