Leaking Velux / Bad Installation

Hi guys. Got a couple of questions. I've got a property where the developers fitted a Velux window where I'm sure they shouldn't have. It's a curved metal roof, pitch is very low, I've not measured it but will do next few days.

Question 1
When it rains the mini-side gutters seemingly overflow and water comes inside. I've been up on the roof, cleared out any debris and sealed between the wood and the metal. Whilst an improvement I don't think this will contain all excess water when it rains hard, I can see the water seeping over the wood. Anyone had this situation before, any solutions apart from completely sealing the window?

Question 2
The developers did a real hash job on the installation. Looks really untidy. Ideally I'd like to box-in the bottom, where you see the black seal tape. Not 100% if this is feasible? Failing that idea can anyone recommend some decent flashing material?

Any help much appreciated, thanks

Is this a new build ?

If it is get the developers back to sort out your problem don't settle for substandard work

We have got roof lights and suddenly water coming through. Ours are Fakro ,but that does not matter.
I thought the leak was because water was tracking back in and could not find a blockage. I even had roofers out who happily picked up some leaves and debris on the roof with no real solution. I then started looking at the internal window seals and they seemed to be the problem. There are some thin strips of rubber at the upper end of the roof light. They are supposed to make contact with seals on the frame. There might have been some movement / shrinking and the lip is making full contact anymore.
I stuck some self adhesive draught excluder under the existing rubber seal strips trying to "prop" the seals up / support them to make contact again in the closed position. This seemed to have helped.

Hi Mrpugster, Velux windows 17 years ago are not like they are now. The fitting of that window has been bodged from the start. No tile overlay fitted, which likely means the original sealing system wasn’t put in place. Can’t see from the photos a point of entry for the damp. So the solution could be to use a liquid plastic system to seal the whole window and any joints aligned to the window. The other is get a new velux or other reputable roof window and have it fitted properly. Hope this helps.
