Whereas skylights are useful for letting in natural light, they do have their problems that you should be aware of before installing a skylight. One of the common problems skylights face is that of water leaks. Keep this in mind while installing a skylight so that you can include leak-proofing measures:
Have It Properly Installed
The best thing you can do for your skylight if you don't want it to leak is to have it professionally installed. In fact, this is one of the reasons DIY installation of skylights is discouraged. For example, the connection between the roof and the skylight should be tightly sealed to prevent water from getting through it. Also, the skylight needs to be installed on the roof because installing it flush with the roof will encourage leakage. These are the sort of details that a professional will not overlook but an amateur can easily overlook.
Keep It Free of Debris
Debris on the skylight, or anywhere else for that matter, will encourage water leaks in different ways. The debris will attract and retain moisture on the roof and skylight, and the longer the skylight remains moist, the more it is likely to leak. The debris will also accelerate the deterioration of the seal between the skylight and the roof, and this also makes it susceptible to leaks. Therefore, clean the roof regularly to prevent this from happening.
Ensure the Attic Is Properly Ventilated
On first glance, there doesn't seem to be a direct connection between attic ventilation and skylight leakage, but there is. There are two main ways poor ventilation can lead to moisture problems on the skylight. First, it will allow moisture-laden air to collect on the underside of the skylight, and the moisture will condense and fall back in your house. Secondly, the condensation can affect the skylight seals and allow leakage from above.
Get Rid of Roof Snow
Snow on the roof is always a bad idea not only for your skylight but also for the rest of the roof. If too much snow accumulates on the skylight, it can cause minuscule cracks that can let water seep through the skylight. Not only that, but the accumulated snow can also lead to the formation of ice dams around the skylight, which will eventually cause leakages too.
The risk of water leaks is also one of the reasons you should avoid DIY repairs of leaking skylights. These projects are best handled by professional roofing contractors at companies like Todd Harkleroad Roofing Inc.
