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.

  • Dawn Johnson
    He was very informative and knowledgeable about the company and I loved his presentation of the product .

    Rob O., the project consultant, came out and took a look at my roof and my attic. He taught me so much! He spent a great deal of time and explained everything. I felt educated on what could be done, and what could wait. Compared to the other bids I had, G. Fedale was exceptional so I chose them to do the job.
  • Eric Zerbe
    While we were deciding what to do about a leak in our roof, news came about a nor’easter heading our way. I called G.Fedale to see if they could help somehow in the interim, and Jen and Leslie immediately looked for someone to help, which came in the form of Aaron and his technician Jeremy, who made temporary emergency repairs to our roof’s problem area the same day and within an hour. We’re lucky and grateful for their help!
