After the rain last week, a piece of soffit fell off, and on inspection the lead valley appears to be leaking. No damage that I can find to actual str uctural timber, just the piece of wood that the soffit was nailed to. I've cleaned the wood out, and applied wet rot hardener.
1930s house, slate roof, plenty of slipped slates, but none that would have any bearing on this. Found a piece of flashband (I think, and there's no r eason to suppose the previous owner did anything fancy like welding a plate on) over the lap between two sections of valley. I'm looking for bodge it again. I don't need a repair that will last for more than two years, possib ly even just one winter (quite likely we will do a loft conversion in the n ear future, and we will definitely redo the whole roof at that time. Is the simplest option to replace the flashband? How would I go about getting it off? I think I'll be happy working with a roof ladder and a belay over the ridge from my climbing gear, though I might just hire a tower.
