Leaking "velux"

[opps]

Hi all

I am currently repainting my customer's block based "summer house" which has a wood shingle roof.

When it rains fairly heavily, a thin stream of water runs from the lower right corner of the Velux reveal and down the wall. All the way around the reveal about an inch of paint had previously flaked away. I started working there on Sunday. The only section that has shown damp (when it rains) is the lower right corner of the reveal.

I did pop my head through the Velux and noticed lots of ivy and dead leaves from the tree above. I pushed the ivy and leaves away, in the hope that it would sort things out. It was still leaking when I got there this morning.

I noticed that there is some kind of flat 90 degree metal flashing running under the shingles. I am guessing the roof pitch is about 30 degrees.

I am wondering if the build of moss and crud is contributing to the problem. There is still a bit of gunge (as you look from the outside) where the lower shingles meet the metal flashing at the point where the water is visible. I won't be able to look at the exterior of the upper part of the windows until tomorrow- the room has lots of furniture, which I move each day in rotation.

Suggestions as to what to look for when I am able to gain access will be much appreciated.




I will post more images when I get a chance.

Tnx

Thanks.

It doesn't seem to have side channels, just the thin right angle zinc? The shingles seem to butt up to the window frame.

I have a sneaking suspicion that the roof is plywood with the timber shingles pinned directly to the ply. I am starting to wonder if the builder failed to properly "glue" the zinc to the ply and that the water is running under the shingles and along the ply and then under the zinc.

I will try to take exterior photos tomorrow.

Nah, that is just the way I walk...

Will take the photos tomorrow. Feeling a bit jaded today. Did 3 hours and left. Am having a restorative pint at the moment...
