Old lead valley

Troublesome ageing lead valleys and flat roofs are the source of many leaks. Many a time the lead lengths are too long leading to stress cracks. Strip the lead out (or leave as base former) and form a new valley using modern blends of fibreglass & resins followed by a choice of top coats. GRP will out last felt and lead easily if laid well and often qualify for 20 yr plus guarantee's. Bonus also is that the GRP probably costs less than lead too.
