When making choices about the roof of your home, you may have a tough time choosing between a skylight and a roof window. The two provisions basically serve the same purpose but a few differences set them apart. First, roof windows are designed for a reachable roof. This is because they are capable of closing or opening just like the windows on your wall. A skylight on the other hand may be fixed or movable depending on your preferences. But many are the times when they are both fixed and unreachable. Other times, they are motorized or connected to sensors that control their opening and closing patterns according to the settings. Roof windows are also made with a sash meant for cleaning them. It is on the outside but controlled from the inside adding to its convenience. But the quality of glass used for the skylight is often of much better quality than the one used for windows. The skylight will also often have the provision for such accessories as blinds or shades while the roof window does not make any provision for privacy. Some are light sensitive or capable of responding to external features in a way roof windows cannot.
