Rendered stacks may look tidy at first, but exposure to the elements will eventually cause cracking and spalling. Traditional terra cotta chimney pots are a valuable commodity and should always be retained or replaced in kind. Second-hand pots are usually available, and new pots in many traditional designs are now readily available from various manufacturers at reasonable prices. Most roofs in the West End are still clad in traditional grey West Highland slates and these should always be retained. Modern concrete tiles should be avoided as they are inappropriate for Victorian buildings.
Some artificial tiles can nearly double the loading on old roof timbers and masonry walls.
These embellishments add character to the building. TV Aerials and Wiring Avoid letting your building become cluttered with too many TV aerials and wires. Repairs will be easier and cheaper in the long term. Always ensure that any redundant wires or aerials are removed from the roof or stonework, and ensure that loose wires on the roof are secured to avoid damage to the slates during high winds. Multiple wires running down the building walls should be bundled together and tacked to the masonry.
