One of the most common problems with skylights is that they leak. If they do, the problems that you face are too many to ignore. So, while skylight replacement or repair is one of the first things that you should do, here are some important things that you should know before considering replacement. It is common knowledge that bad weather and ice build are the prime causes for skylight leaking. However, if you find moisture dripping inside the house, it does not necessarily mean that your skylight is leaking. So, do not be in a hurry to replace the skylight until you are sure about the problem. Usually, certain things inside the house can cause condensation to form on the inside of the skylight. At the outset, this condensation gives the impression of a leaky skylight. Electronics such as washing machines, steamers, dryers and hot baths can increase moisture in the interiors and cause condensation to form on the skylight. You can find this very frequently during cold winters. Since ice buildup and bad weather are also the prime reasons for leaky skylights, you might misunderstand the condensation to be a leak. This is why you should never hurry into skylight replacement. However, if leaks are caused due to cracks or damage to the pane of the skylight, you should consider immediate replacement.
