Woke up two days ago to find water dripping down the wall of the spare room. After a bit of investigation (boiler above was originally prime suspect), we found the wood beam supporting the dormer valley to be soaked, and a roofer confirmed there a crack running across the lead flashing half way down the valley. Valley itself is done in a single piece of lead, but is probably not much longer than 1.5m. Think the synthetic slate roof was redone 20 odd years ago before we moved in, so in reasonable nick.
so far I’ve had three people to quote and three different options (four if you include complete replacement)
a) paint on some sort of roofing sealant paint down the full length of the valley (that’s a no from me ..)
b) weld a patch over the crack
c) flash band it
No-one had proposed a sleeve (if I understand it - take off a few tiles around the crack, cut the lead and add a piece under/over, then replace tiles). Looks great solution to me, but I’m just a you-tube warrior, so what do I know!
So far c) is by far the cheapest quote, as he can do it without scaffolding - it can also be done quick, and there’s a lot of rain forecast. I’m having to manage the situation with towels in the loft, as there’s no drip I can catch - so that’s a factor.
advice ? I’ve got one more person coming round later, what would you recommend I ask?
