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 Synergy Skylights and Roofing - Holliston MA 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
1 Day Total*

    Excellent service very professionally conducted. Skylights and rubber roof installed in one day plus a half day to complete interior work. Cleaned up all the debris. Looks beautiful. Thanks!!

    Professional from start to finish. I would not hesitate to use Synergy Skylights again, or to recommend them. They replaced two older skylights and everything went smoothly, on time and as promised. Good communication and very clean.

    Recently we replaced our 30-year-old skylight with Synergy and the experience was excellent. Laureyn was responsive to our initial inquiry, came on site to explain the process and the skylight options, provided a timely quote and arranged for installation seamlessly. The skylight installation took place on the date and time stated and the work area was spotless – as promised. It’s not often you experience this level of quality and responsiveness. Great job Synergy!
