Five easy steps on How to repair a skylight
Many types of skylights
Some skylights are for pitched roofs, and others for flat roofs only.
Skylights have the function of bringing natural light into a dark area in a building. So often they are the primary cause of a leak in a roof. Most of the time they do not leak from the beginning, but it will take several years to become a problem.
On a shingle roof, the flashing will get clogged with debris, and in turn, the water will get diverted under the shingles where it could start leaking.
The other issue is if the installer nailed the shingles through the flashing, then those nails could start rusting and cause a skylight to leak.
Most of the time it would be debris collecting on the top end of the skylight that causes the leak.
Another issue could be that the seal between the frame and the glass could dry out and start leaking.
What is the difference between a flat roof and a pitched roof skylight?
Most of the times its the flashing. A skylight that is for a shingled roof will have step flashing. It is important to weave the step flashing into every line of shingles.

Thermal Performance Of Flat Roof Windows
The U value is a measure of the thermal effectiveness of any glazing unit and this information is usually available online, though sometimes it takes a bit of sifting through to get to.
The thermal performance of a flat rooflight is no different to a vertical window.
It is determined by the quality of the glazing and the way the glazing units and the surrounds have been constructed.
Generally speaking, the lower the U value the better. Look for a U value below 1.5, which represents the heat loss score of a good double glazed window. Triple glazed windows will have an even lower score, below 1.0.
Are Flat Roof Windows Any Good
Flat roof glazing is a brilliant way to get lots of light into the space below. It is said that you get around three as much light from above than you do through a conventional vertical window and there isnt any time of day when you are not collecting that light.
There are many modern designs where big open plan spaces would be dark and unwelcoming without overhead light.
They have to be carefully installed to ensure good waterproofing. This is normally achieved by building a small upstand which acts as a base wall for the rooflight to sit on. Whilst domed rooflights can be laid horizontal, genuinely flat ones need a camber to ensure good rainwater run off.
In really hot spells, you can accumulate rather more heat than you want in the room below. There are ways you can mitigate against this, including fitting solar control glazing which reflects sunlight. It is best to limit the amount of overhead glazing to no more than 20% of the floor area you wish to light.
