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 New York Skylight Installers 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 had to replace an old velux skylight in a bathroom and I chose a certified Velux installer rather than a roofer. Dan from sales and Chris the installer helped me choose a replacement of similar size. It helps that Chris did the preliminary measurements etc. I wanted to get the job done before the holidays and and they worked with me. They brought matching roof shingles and the installation was clearly done with skill and experience in one morning by 3 men. I would recommend this company without hesitation. For homeowners in a similar situation you still have to do your homework as this is not a simple job, The Velux web site could be better. My new window also requires Sheetrock changes inside the bathroom which I now have to do separately.

    I had a great experience with Dan and Chris, but more importantly no leaks after a new Skylight Installation. I initially explained my needs which they addressed and resolved.

    In researching skylight replacement companies, I came across NY Skylight Installers and I'm so happy I found them! From start to finish everyone I spoke to and worked with were professional and knowledgable. Chris and Jorge came to do the installation yesterday and it went flawlessly. The skylight they replaced was an old pyramid type, and this new model is not only UV rated and clearer to see through, but made the whole room quieter from outside noise. We're absolutely thrilled and can highly recommend New York Skylight Installers!
