You can usher in some fairytale magic into your house by installing a flat roof skylight. There is no doubt that a skylight can allow more light to enter into a room than a vertically located window. However you need to remember that there are specific skylights for different roofs. For example skylights for sloping roofs are designed differently than the flat roofs. If you ignore this vital point you may have to face severe problems in the near future.
The important facts
The skylights for the flat roofs are specifically domed to facilitate drainage as it is a known fact that flat roofs suffer from drainage problems. To prevent water pooling on flat roofs the experts encourage domed skylights. Now if you are using a flat skylight you have to take care that it is pitched at a minimum of an inch of the width of the skylight.
You also have to make sure that a skylight with minimum pitch is compatible with flat roofs. There may be instances where a skylight is not pitched for roofs with low pitch and can only be used after adding a bit of slope. You can learn all about this in the literature that you will be supplied with. If by chance the drainage mechanism is not compatible with the low pitch it will be an utter disaster. So you understand the seriousness in judging the compatibility of this device before you go ahead with the process of installation.
