The trick to create the feel of spaciousness life, cheer and value to your home is to illuminate it properly. A skylight installed on the ceiling allows more light into the room than a vertical window. However, you have to make sure that the right kind of skylight is accompanied by the specific roof type. For example, flat roof skylights are designed differently from those for sloped roofs. One must consider these factors before installing the skylights on the roofs. Skylights that are used for flat roofs are usually domed in order to promote drainage as these roofs are more vulnerable to drainage problems. The chances of water pooling are more if flat skylights are installed on these roofs. Hence, roof skylight experts suggest using dome skylights for such roof types. If you are using a flat profile skylight, do make sure that it is pitched at the minimum of one inch per foot of the skylight's width. It is also essential to make sure that the skylight, with its minimum pitch established by the manufacturer, is suitable for flat roofs. Sometimes, a skylight might not be intended for low-pitch roofs or can be used only after adding some significant slope. Skylights with poor drainage mechanism, will fail soon. Therefore, it is important to judge the suitability of such sunlight before installation.
