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

    The team has installed a Velux skylight in our studio, and went way above and beyond. They didn't just do the skylight (which looks really cool :)), but removed the old ceiling fan, installed a new one in a new location and were super-flexible with the timeline: a piece of new ceiling fan got delayed and didn't arrive on time, so they had to come a second time weeks later to accommodate for the delay! Big thanks to Manny, Joey and Luis!

    We had such an incredible experience working with Skylight Pros. Their team was thorough, punctual, and fair. They were on time and cleaned up the job site every day. We are OBSESSED with our new skylights and would recommend Skylight Pros to anyone and everyone! What a joy to work with!

    After researching skylight companies and seeing the same complaints about competitors—poor communication, delays, and subpar workmanship—I was hesitant, but Andres and his team at Skylight Pros completely exceeded expectations. Their team was responsive, professional, and transparent from start to finish, showing up on time and delivering clean, high-quality work without cutting corners. The installation was seamless, and you can tell they take real pride in their craftsmanship. Just as important, their customer service was consistent throughout the entire process, making sure everything was done right. If you’re concerned after reading negative reviews about other companies, Skylight Pros is the clear choice—they truly deliver on both quality and service.
