Roof Valleys

Roof Valleys

It is not often you get a good view of a valley: a central drainage channel between two roof slopes.

Here, there was a skylight which when opened revealed this leadwork valley centrally positioned in the roof of an 18th century building.

The lead itself is in good condition. Valleys like this need checking as they can easily allow rainwater damage due to either bad initial design and workmanship or blockage by leaves and other such debris causing rainwater to overspill and not drain away freely.

They need to be checked by a competent roofer from time to time to ensure this does not happen. At this time check for other defects which need attention. Here there is a slipped slate which needs refixing.

It is easy to neglect maintenance in hidden situations such as this. Prevention is better than cure!
