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

    We had several skylights replaced by the Synergy team and we couldn't be happier with them! Laureyn responded very quickly to my initial inquiry with a call and clear expectations regarding the timeline and relevant info for the job. From the first call, I greatly appreciated her ability to communicate. But her value didn't end there. She is trustworthy, smart and dedicated to providing a top tier product and installation. You can absolutely trust all the people raving about this company. They've earned the stellar reputation. Thanks so much!

    Received estimate with options for replacing two skylights and had them installed per our preferences. Outstanding experience in all respects: clear explanation of option pros and cons, ease of communicating our constraints on accessing roof while other work was being done, prompt response in all communications, skillful and efficient installation work, careful matching of roof shingles, flawless operation and appearance of new skylights. Highly recommended!

    I contacted Synergy to replace my 35 year old skylights. They were responsive and very professional. They gave great details about what they were going to do and cleaned up before leaving the job site. The work they performed was high quality.
