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

    I had a great experience with Laureyn and Nick of Synergy Skylights. They replaced my skylight. They spent time patiently answering my questions and working with my budget. The installation was smooth. The installers were prompt, pleasant and left a clean space. I have already recommended them to my neighbors.

    Had a positive experience with Synergy from start to finish. Lauryn and Nick are a pleasure to work with, professional, and reliable. The repair/reglazing job caused no stress from contract to completion and this is how it should be. Would recommend for Wasco/Velux skylight repairs.

    We are very pleased with the new skylights and their functionaloity. All work was completed and cleaned up and the installer ( I am sorry to not remember his name) was professional and explained all the work and how the skylights work.
