Repairing lead valley - fibreglass paint repair?

    Had a roofer over recently and he said the lead valleys are starting to split in places. He recommended a 2 coats fibreglass repair job.

    I've not heard of this sort of repair before - anyone got any experience with this or know is it just a temporary fix or actually permanent? Advice appreciated

    How old is the lead valley? If done well, a lead valley should last a very long time. It is a high quality material, not used in many countries and it seems a little sad to be paying someone to repair it with fibreglass.

    Temporary fix. I just read a comment recently where someone said they were advised that different expansion rates of the two materials would cause the fibreglass to crack over time.

    We had our lead valley replaced because it was split in multiple places. They didn't repair it they completely replaced it with a fibreglass valley. Not sure of the cost as it was part of a much bigger project but seems a great job so far.

    You would be literally painting over the cracks. Do it once and do it right .... replace it.
