Installation Process

Expert installation made easy.

VELUX® skylight systems and Sun Tunnel® Skylights can be installed in flat or vaulted ceilings in two worry-free phases: rooftop and interior. The pros will recommend where skylight systems should be installed, so you can reap the maximum benefit from the natural light and fresh air they provide.

Installation Types

The Room

VELUX-trained pros will come inside for interior finish work and possible painting. If you have a flat ceiling, your installer will use drywall or other finish material to build a shaft from the skylight to direct the daylight into the room. This phase takes around half a day per skylight.

The Rooftop

VELUX-trained pros will cut a hole and fasten the VELUX skylight to the roof with three layers of protection to prevent leaks. Depending on the circumstances such as roof pitch and weather, the rooftop phase can take between one and three days.
2-3+ Days Total*

The Room

VELUX-trained pros will cut a hole in the ceiling to install the lower portion of the reflective tube between the roof and ceiling.

The Rooftop

VELUX-trained pros will cut a hole in the roof and install the top collar, the upper portion of the reflective tunnel, the lens and the flashing.
2 Hours*

The Room

There may be a small amount of interior drywall work depending on your replacement situation, but the majority of the replacement process will take place on the roof.

The Rooftop

VELUX-trained pros will get measurements from your existing skylights to ensure your replacements are a perfect fit, then they’ll replace your skylights

    ​Exceeded my expectations! When I purchased my house, I knew I had to pursue a skylight installation because the kitchen was quite dark/gloomy from the overhanging patio just outside the only kitchen window there is. I'm so glad that I did! It has made such a HUGE difference and all the natural light it brings in is amazing! It not only looks modern and updates my kitchen, but its also more welcoming and widens the room. From start to finish, it went really smoothly and everyone I interacted with was very friendly and professional. Julia was extremely helpful and great to work with in providing information, what to expect and answering any questions I had. Nick and Jake did my skylight install and they did a phenomenal job! I requested that the flare of the skylight be as wide open as it would allow and they accomplished what I wanted. They also installed the lighting for me, which was such a huge help. I am very appreciative and love my new skylight! :))))))) The before/after pictures speak for themselves.

    Wish I had this done years ago! We have a "flat roof" with no real insulation. We had the original bubble style acrylic or plastic skylights from the 1960's. Our house has always felt cold and drafty. Now with our new Velux skylights, it is the first time our home feels truly comfortable. An added bonus I didn't even realize until after installation is that closing the blinds adds an additional layer of insulation which will be nice on a cold winter night. Everything about the whole process was very well explained by David Ackerman and then Jordan Barnes came out and did the install. Very pleased!

    This is the second skylight that we bought from Skylight Specialists. We were happy with them both times. They are excellent quality. Joseph, who installed them, was professional, competent and pleasant.
