Roof valley repairs FAQs

Roof Valley Repairs Questions and Answers

These answers explain common questions before you request a quote.

Can you see a roofing problem?● Send us a photo
Why do roof valleys leak?+

Common causes include split lead, failed laps, blocked channels, displaced coverings and deteriorated underlay beside the valley.

Can a lead valley be patched?+

A small suitable repair may sometimes be possible, but heavily split, badly formed or repeatedly patched lead may need renewed.

Should moss be removed from a valley?+

A clear water path is important, but cleaning should not damage fragile slates, tiles or leadwork. Safe access and roof condition come first.

Can water enter even when the valley looks intact?+

Yes. Faults may sit beneath the adjacent covering, at the top or bottom of the valley, or within hidden underlay details.
