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 at Rocky Mountain Skylights 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
