Chimneys, flashings and valleys on bigger roofs
On a large period roof, the trouble spots are usually the details. Lead flashings around chimney stacks and wall joins can lift or split with age, mortar on stack tops can crumble, and valley gutters between pitches can silt up with moss and leaf litter. Any of these lets water run behind the covering.
Chimneys that are no longer used still need attention, because an unlined, uncapped stack can take in rain and send it into the walls. Pots, flaunching and pointing are inexpensive to check but costly to ignore. We look closely at each junction before suggesting anything bigger.
