We've had a lean to garage constructed. It has a polycarb roof running into a wooden valley gutter. It's quite long (6-7 metres) and runs around next doors chimney breasts.
The valley is flat I would have expected it to slope to help the water run off.
The main problem is that it leaks. The felt has been reapplied and built up so it's leaking less but still not watertight.
I'm uneasy about settling the bill (we've paid half), it looks like a patch up job and I'm not convinced even if it stops leaking that it will stay watertight.
Any advice pls?
