What’s the best approach to fixing this?
Completing a bathroom renovation and I’ve got a gap between the wall tiling and the roof. The biggest issue is pictured here, it’s about a 10mm to 20mm gradually increasing gap.
There is a joist directly behind the gap, but I just really know how to tackle this one. I want to avoid a cornice if possible, but I don’t want to rip out the roof either.
Can anyone share their professional advice on how best to approach this issue so I can complete the renovation?
