Skylight air circulation
Aside from great light and air circulation, skylights can also bring you trouble. All depends on how you install them and on the quality of the skylights.
Starting from the main advantage of skylights, which is bringing more light into a room, we can say that this can turn into a real trouble.
Another bad thing about skylights is that they are hard to reach when you have to clean them. You must take the risk of climbing on the roof with a ladder and that is dangerous.
There is another problem that homeowners complain about, condensation. Usually this is a very common problem for old skylights because the way they are designed and usually the material, which is plastic, just favors condensation. Also if the skylight is installed badly condensation conditions are created.
