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

    I cant say how grateful I am for Paul, John, Brian and their entire crew. They really did an amazing job with my home for my roof replacement, entire gutter system replacement and gutters screens. The job and process from start to finish was nothing but amazing and flawless. They took care of all my concerns and I cant thank them enough. Perfection at its greatest! Godbless all of you and Thank you 1000 times. I would give 100 stars if I had that option. Thank you and have a happy and healthy new to all of you.

    I wanted to convert one of the walls in my living room from a regular wall to one with bricks. After getting an estimate, I hired them after making sure that they sent me their proof of insurance. They did a great job. It took about 3 days to complete. I was quite pleased with the results. Kudos to Paul and Jose for their diligence and the final result. It shows the rustic feel that I was going for, like in restaurants. Some before and after pictures attached.

    Great prices, very professional and great communication. Paul did the free inspection and he was very informative and honest. I had multiple roofers before and he was by far the most knowledgeable and honest, it was refreshing to talk to a craftsman and not a salesman, which ironically sold me. The guys that came out to do the work were also great, efficient, and professional. I am particular about who does work on my home but Five Boro gave me no room to complain 👏🏼
