Slate, copper and built-in gutters
Some older houses in the area still have slate, which can last a very long time but needs skilled hands. Slate tiles slip, crack or break as nails rust, and a repair is a matter of replacing individual tiles, not the whole roof. Copper flashing and valleys can also be found, and they are worth keeping where they are sound.
Another feature of older homes is the built-in or box gutter, hidden behind the eave. When it clogs or fails, water runs into the wall. Those gutters need regular cleaning and, in time, relining. They are often the cause of a leak that seems to come from nowhere.
