How to Install a Tubular Skylight Part 3 How to Install a Tubular Skylight Part 3

What You'll Need
Tape measure

The tubular skylight is a modern popular feature which can be installed throughout the house. First invented in the 1980s, it allows more sunlight to fall directly into a home, and can also form an attractive feature by itself. If you have an attic, or large area above your ceiling which could be used as a light source, then you should try fitting in a tubular skylight, and seeing the light difference benefit your living area. In steps 1 and 2, you cut away the roof, and installed the tubular dome. In this final step you will have to make your hole in the ceiling and fit the final part of the light

Step 1 - Cut the Ceiling

Measure the area where you want the hole in your ceiling to be. Find the middle of the area you want to cut, and draw out the size of the hole you want to cut. You can either mark this by following a line down from the top of the dome, and placing a hole in the ceiling, or by measuring it out on the room ceiling using a tape measure and a pencil. From there, echo the measurements that you used to cut a hole in the roof, ascend your ladder, and then cut out the ceiling using a saw. You may want to put down some newspaper below the hole in order to collect any plaster and bits.

Step 2  - Connect the Tube

With the hole made in the ceiling, you should start fitting together the tube for your skylight. You may need to screw pieces together, so make sure that you have your screwdriver to hand before you start holding the pieces together. Once you have the tube assembled, then put the pieces up through the roof, and then attach to the roof flashing which you installed in part 2. Use your screwdriver to screw all of these parts together, and then place some caulking around the edge of the tube nearest to the flashing, in order to keep all the parts waterproof.

Step 3 - Fit the Skylight

In the room with the hole in its ceiling, assemble the pieces of the skylight, and then place them all together. You can then fit them onto the edge of the ceiling. The main circle of the skylight, known as the flange, should be fitted first, and connected to the tube from the attic. There are several screws here which will need tightening as you proceed. When you have finished screwing the flange into place, put caulking or tape around the edges to ensure that they are all water and air tight. You should then lift up the other parts of the skylight, and screw these into place on the flange. Make sure that all the parts are well tightened before you finish
