Tile Roofing

DSCF1691
Roof tiles are designed mainly to keep out rain, and are traditionally made from locally available materials such as clay or slate. Modern materials such as concrete and plastic are also used and some clay tiles have a waterproof glaze. A large number of shapes (or "profiles") of roof tiles have evolved. Roof tiles are 'hung' from the framework of a roof by fixing them with nails. The tiles are usually hung in parallel rows , with each row overlapping the row below it to exclude rainwater and to cover the nails that hold the row below. There are also roof tiles for special positions, particularly where the planes of the several pitches meet. They include ridge, hip and valley tiles .

Similarly to roof tiling, tiling has been used to provide a protective weather envelope to the sides of timber frame buildings. These are hung on laths nailed to wall timbers, with tiles specially moulded to cover corners and jambs. Often these tiles are shaped at the exposed end to give a decorative effect. Another form of this is the so-called Mathematical tile, which was hung on laths, nailed and then grouted. This form of tiling gives an imitation of brickwork and was developed to give the appearance of brick, but avoided the Brick Taxes of the 18th century.


Felt Roofing

P9021023
Felt is a non-woven cloth that is produced by matting, condensing and pressing woolen fibres. While some types of felt are very soft, some are tough enough to form construction materials. Felt can be of any colour, and made into any shape or size.
Felt is made by a process called wet felting, where the natural wool fibre is stimulated by friction and lubricated by moisture (usually soapy water), and the fibres move at a 90 degree angle towards the friction source and then away again, in effect making little "tacking" stitches. Only 5% of the fibres are active at any one moment, but the process is continual, and so different 'sets' of fibres become activated and then deactivated in the continual process

Slate Roofing

P9291078
Slate can be made into roofing slates, also called roofing shingles, installed by a slater. Slate has two lines of breakability: cleavage and grain, which make it possible to split the stone into thin sheets. When broken, slate retains a natural appearance while remaining relatively flat and easily stackable.

Slate is particularly suitable as a roofing material as it has an extremely low water absorption index of less than 0.4%. Its low tendency to absorb water also makes it very resistant to frost damage and breakage due to freezing.

Lead Works

SDC10153
Our company also offer different forms of lead roofing. Lead is one of the oldest and most durable roofing material and good understanding it's nature and following certain rules require some skill. We can investigate fault and determine cause of potential defect to provide best solution.
The decision on whether to repair or renew can be influenced by many factors. A parapet or central valley gutter lining may be in a fair condition and on its own, worth repairing to extend life by another ten to fifteen years. But if the adjacent slated or tiled areas are to be renewed, the relatively low cost of re-laying the lead gutters would be well worth accepting.
