One of the main problems with installing dormer windows is location. Oftentimes, the place where you want the skylight has a ceiling that is not near the roof. In other words, there is an attic between them. There are two main solutions here. The first is to make lamp shafts at a construction site using ordinary building materials. The axle, which is sometimes quite large, connects the ceiling to the roof.
Another problem is the proper installation of skylights in Australia via https://www.naturallighting.com.au/product-category/skylight/. Today, many builders prefer self-flashing models for level installation. Just remove the right number of roofs, cut the holes to the right size, and attach the roofs over them.

The flasher used to protect against water is equipped with a device and you change the roofing material directly above it. For more economical models mounted on the edge or curb, the curb should be fixed on the roof to fit the skylights and make the elements flicker on site. Professional installation is required.
If the sunroof isn't installed properly, it actually leaks. For this reason, professional installation is recommended. However, the master of his own hands, who bought a self-flashing assembly module and carefully followed the instructions, should have no problems. Be careful not to install skylights on the tile roof. The roof itself is brittle and stepping on it incorrectly can cause the tiles to break.
The final problem with the installation is the weather. It goes without saying that after installing the skylights, you will choose a day when rain is not foreseen. You don't want any holes in the roof when it starts flowing. Raise your feet and don't let the work begin unless the sun is shining.
