===========ORIGINAL MESSAGE ==================
I have a skylight in my bathroom on a very high and steep roof. I noticed brown drip stains on the edge of the ceiling (the roof is surrounded by trees so the brown is from tannins) and on a rare occasion the droplets make it to the floor but I've only seen that twice in 2.5 years. I notice the drip stains mostly when the snow is melting (not when it's raining). Is this just condensation or would it be leaking? The odd thing there are clear the drip stains which start (or only show) mid-way down (not from the very top) that run all the way down to ceiling as you should able to see this from the pictures. Just trying to make sense of this and if there are any preventative measures I should be taking.
Additionally, cleaning is virtually impossible unless I can manage to get an extended ladder in a small bathroom. An extended handle on a broom or mop wouldn't be long enough - any ideas how to clean the dust and other debris that has accumulated?
Hopefully the pictures give you an idea of the situation - but the finer detail seem not to show in the pictures online as they do on my phone.
