Tubular Skylights

Tubular skylights are typically 10 to 14-inch diameter tubes that are installed directly into a roof. Then, the lights are covered with glass or even plexiglass which lets natural light into your home. These skylights have the exact same illuminating effect of a few 100-watt light bulbs. They are capable of lighting a 200-square-foot room.

To soften any glare, these tubes will have a diffuser in one end. However, because you’ll have a tube stuck in your roof, there will not be a view provided, unlike fixed or vented skylights. Fixed skylights vary widely in price, costing anywhere from $150-$1,000. A fixed double-domed skylight starts at $450+.

Installation Requirements

Since the installations don’t need alternations to framing, there are not many limitations as to where you will be able to locate your light tube. Remember and check the attic, ensure there’s enough room or you to do a straight run. However, should you come across an obstruction, you can always use elbows and/or flexible tubing to go around it. Vaulted ceiling makes it easy to install light tubes as you will only need 12 inches off tubing (take or give an inch).

The following evaluations should be made in advance:


Living in an area that has high humidity can cause condensation to the interior of the tube can cause issues. You can cut down on the amount of condensation by wrapping the tube up using (R-15) or (R-19) insulation. There are a few manufacturers who provide sections of tubing that have small fans built in to them to help in removing any moist air. Anyone living in an area that is prone to hurricanes can opt to have an extra hardy dome made of poly carbonate.


You will get the best results from your globe if it is mounted on the southwest side of the roof. In choosing the spot where to run the tube is required to make sure that it is 14 feet in length, or less. I you place the globe right above the target room, it could convey up to 98% more exterior light. If the tube is able to twist and turn, you will get a minimal amount of light.
