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 Skylight Pros by Blue Bell 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

    First off, we love our skylight SO MUCH! Every South Philly rowhouse needs a skylight over the stairs, in my opinion. And I can't imagine a better business to work with to put that skylight in. Joe and Rita were SO kind and solicitous that the cynic in me thought it had to be fake -- until Joe showed up with the crew and was equally as kind to his workers as he had always been toward us. Highly, highly recommend.

    Superior professionalism, excellent communication, fine craftsmanship, thorough inspection and cleanup. These qualities of Skylight Pros of Blue Bell earn our 5 star rating. From start to finish Joe and Rita were easy to work with to replace our 20+ year-old Velux skylight. We highly recommend this company.

    Blue Bell helped us replace two skylights. Rita and Joe are very responsive and professional to work with. I shopped four companies before choosing to work with them because they are the most professional and honest. Some companies gave me a super inflated price at first and then offered a discount after I got other quotes. Rita and Joe gave me the right price from the very beginning. The installation was delayed for a few weeks because of the rain, and Rita was very proactive and communicative to help us rescheduling. The new skylights look great, and we're very happy to have worked with them!
