    I have a bungalow with a concrete tiled roof and the concrete valley leaks slightly in heavy rain.
    I've attached some pics of the valley which looks to have had bitumen sealant applied at certain times during its life.
    Based on the pictures, what do you think is the most appropriate fix? I presume a new valley is the best solution which can be done when the roof is replaced, but what is considered the next best fix and what would be the likely cost (SW England)??

    Horrendous idea - overlapping concrete valleys are a clumsy nightmare. Yours looks like it's had its fair share of trouble too and has been mortar bodged to within an inch of its life.


    I'd bite the bullet and replace with trouble free dry valleys.

    As above for sure. OP youve got no choice.
    But your troubles might increase when you lift the tiles either side of the valley. ive seen similar where the felt and even the laths have been stopped to short and the woodwork below is beggining to rot, by whoever tried to codge in similar valleys
