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

    New larger size gutters with the cream color matching the house trim look awesome!

    What a great company to work with! Called for gutter replacement. Sales rep/estimator came the next day. We talked for quite a long time. Very pleasant guy and absolutely no pressure before walking around the house to review the current situation and take measurements. I had the estimate that evening and was pleasantly surprised with the total cost. All inclusive; removal of all old gutters, installation of new gutters (larger diameter) and gutter guards. Installation crew did a fantastic job. They even did some rerouting of downspouts to make them more efficient and less disruptive to the driveway and other areas of my lawn that were very messy. Beautiful job all around. Clean up and haul away of old material. Extremely happy with the finished product.

    Ben came out and help us with the inspection and estimate and then the team came out to do the repairs and all was excellent. Aside from the small footsteps on our roof, we could barely tell they were there. Work was done quickly and they left everything clean. 100% recommend!
