Where the skylights sit on the roof, there is a point on each one (there are 12) where the wall stops and the window just sits on top of it. This means that any drips or condensation can run down the wall and inside the insulation, not good. We needed a lip on the top of the wall for each window, and the thrid bedroom was the perfect place to test the theory.
Luckily, Lorna's wikkid weldin' skillz were just what was needed.
She cut a strip of metal to the right width and welded it into the gap, and we had just what we needed to stop any more drips.
