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 Sun4Light Inc. - Wilmington 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*
*Time estimates are based on averages. Project duration varies based on its complexity.

I have not received better service anywhere in Wilmington! I first contacted this company about blinds for a roof skylight. They informed me that code for skylights changed on April 7th, 2025, & that solar blinds are included with new Velux skylights, & that is more expensive to add them later. I was able to contact my HOA, & paid the difference in cost for the added solar blinds. Sunlight also informed me that, if they were to do the work, it would invalidate my roof warranty (which they looked at). I have never received such good service, anywhere else in Wilmington! If I was not in an HOA, I would definitely use them.

We had them replace our skylight. The whole process from getting the qoute to the finished product was seamless. I had a couple of questions leading up to the installation and they responded in a timely manner. They did a great job matching our existing shingles. The install crew were friendly and efficient. I highly recommend this company.
