Skylights - has yours been installed correctly?
Take a look at this skylight installation that I was hired to repair
Photo “A” is a previously installed skylight that was leaking straight into the roof cavity over a shower of an ensuite and pretty much flooded the tiled floor when it rained.
Photo “B” shows the attempt by the installer to rectify the leak by pumping what looks like an entire tube of silicone on top of the bottom flashing of the skylight. This actually made the water channel back into the unsealed roof.

General Causes of Skylights Leaking
- Leaves or debris build up and block water flow
- Damaged flashing or broken tiles or seals on metal roofs failing
- Incorrect installation of flashing
- The installation of additional perimeter flashing that is not supplied by the manufacturer
- Incorrectly altering roof framework that needs to not only support the skylight but the roof tile battens
- Bottom of the skylight being set lower than the batten height at the bottom of the skylight
- Not enough attention is made by the roof tiler or the skylight installer too ensure the sarking is bridging across to meet the sides of the frame of the skylight with a small turn up and is installed so as any penetrating water can flow towards the gutter
What Can Be Done
- With the above skylight all of the above was carried out as well as a bit more
- An inspection of a leaking skylight would require the removal of roof tiles or even metal roofing. This may involve a fee for the time to carry out this type of inspection.
