Two main types of roof valleys

Roof valleys occur when two roofs meet at an angle. They are designed to ensure that water runs swiftly down the roofs and safely away to the guttering system. There are two main types of valleys – one that is open to the elements, and closed, which simply means that the roofing material covers the valley. Both types should ensure that water runs straight down to the gutters.

Maintenance issues

Because of the amount of exposure to water, it is common for roof valleys to leak, so vigilance and maintenance is important to ensure they work effectively. Open roof valleys have a metal channel or flashing, which is usually made of lead and is installed to protect the roofing material from the water. Closed roof valleys may also have a shield to help prevent the valley becoming blocked with ice, leaves and debris.

Type of roof valley system

Whether you have an open or closed roof valley system will largely depend on the type of roofing material you have. If you have a shingle roof, for example, you are most likely to have open roof valleys. Common issues for roof valleys include becoming blocked with leaves. The metal used for the flashing will also expand and contract with fluctuations in temperature, and this will eventually cause splits and cracks to form.
