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

    From the consultation and introduction with Laureyn to the finished product with Nick, Andrew and their crew this process was flawless. The communication pre and post project was exceptional. Their attention to detail and quality of work made for very happy homeowners. Synergy runs a very well oiled machine from beginning to end. Roof replacement and skylight installation is a messy project…when they left there was no sign that they were ever there. I would shout from my newly installed roof that SYNERGY is the way to go!

    My 3 skylights installed are wonderful. I waited a long time (because of winter weather). Workers were neat and tidy and took pride in there abilities to fit them to my openings. Cleaned up all debris and even washed the windows. They wanted to make sure that I understood how to operate them, and care for them. Very very satisfied, would refer this company and workers to anyone looking for skylights.

    Synergy replaced 4 skylights and 2 side roofs for us, and they did an amazing job! They are incredibly professional, organized, detailed in what they promise and deliver, friendly and have clear expertise in what they do. They came recommended to by a close friend, and I highly recommend them to you!
