Chimneys & Dry Valleys

Chimney stacks and valleys are where roofs fail most often, because they combine multiple junctions, ageing lead flashing, and constant water flow in one small area.

Pro Tech carry out chimney repointing and rebedding using the correct lime or cement mortar mix for the property's age, replace failed lead flashing and soakers, and fit dry valley systems in place of traditional lead-lined valleys where a lower-maintenance solution is wanted.

Every chimney and valley job includes a check of the flaunching and pots, since a stack is only as watertight as its weakest detail.
