Three Main Ways To Confirm Skylight Water Leaks


If you have a skylight, then you should know that the risk of roof water leaks is higher on and around the skylight as compared to other parts of the roof. Therefore, if you suspect that your roof is leaking water, the skylight should be one of the first areas to check. Here are three methods you can use for the diagnosis:

Indoor Inspection

Inspecting the ceiling around the skylight should give you water leak clues, if there is a leak. Here are some of the specific things you should do to diagnose skylight leaks from inside the house:

  • Look for visible signs of damage such as light streaming through cracks
  • Look for water stains on and around the skylight
  • Trace the stains to their highest point; that would the source of the leak
  • Inspect the edges of the skylight, where the skylight meets the ceiling; these areas are more likely to experience leaks than the solid body of the skylight
  • Try to distinguish between actual leaks and condensation from inside the house; the latter is likely if your indoor humidity is relatively high

Rooftop Inspection

Inspecting the skylight from above the roof may also help you diagnose the leaks. Be careful, however, about climbing and walking on the roof because you can damage the roof or fall and hurt yourself. If you have a good ladder and you have experience operating on the roof, however, there are things you can do or look out for to diagnose the leaks.

  • Inspect the skylight for visible signs of damage such as open seams
  • Check if the flashing cement is intact and there are no gaps or bonding failures
  • Look for pinhole perforations on the flashing cement; such holes appear on sealants lose their elasticity

Water Test

Just like the name suggests, the water test involves splashing water on and around the skylight and checking whether it is leaking. Again, you should only do this if you have experience working on the roof, it is safe to do so, and there is a helper who can help you in case of an emergency.

Once you have confirmed that it is safe to work on the roof, pull a garden hose on the roof and let some water fall on the skylight. Work upwards from the edges of the skylight towards the top; this is to ensure you can pinpoint the exact source of the leak. You should have someone checking for leaks inside the house.

Don't do anything dangerous during the diagnosis; for example, don't walk on the roof if it is steep or delicate since you can damage the roof or injure yourself. Call a roofing contractor such as The Roof Doctor to fix the leak once you find it or for a diagnosis and fix if your DIY diagnosis fails.

The Benefits of a Flat Roof

My name is Janet, and I am a professional architect and interior designer. While I love to design and decorate homes, I have recently developed another passion. I have fallen in love with the flat roof. Most people only see flat roofs in tall buildings in urban areas, but suburban homes can have them too. You can have a roof with a living space, a garden or even a pool. You simply need to design it so that water is adequately drained, and you can enjoy your roof almost as if it were an extra room. Explore the possibilities of flat roofs with me.
