The Cotswold roofs are known for the beautiful stone buildings. They complement the beauty with their mellow weathered appearance, sizes diminishing towards the ridge, and irregular edges. Especially in the north of the Cotswold, most domestic buildings originally had straw-thatched roofs. This was when the corn and wheat were more common than the south, much before developing modern wheat strains. The excellent quality long straw was ordinary, reasonable, and was available in local markets.
Cotswold roofs require an angle of at least 45 to 50 degrees to have adequate rainwater run-off. It also ensures water goes out of the walls and the openings of the windows and doors. From the 17th century, Cotswold was used as the roofing of the buildings.
Where do these roofing materials come from?
Cotswold roofing material is not an actual slate in the geological sense. A genuine slate is a metamorphic rock. It is originally a shell that is then transformed by heat or pressure or both into a rock. The Cotswold is made from Oolitic limestone. It is a sedimentary rock. ‘Tile-stone’ is the appropriate term for the Cotswold roofing material. There are some areas where the base of the Great Oolite remains. The laminated tile-stones are usually available near the surface.
How are they made?
There are various instances where a suitable limestone for roofing would either lie close to the surface or present at the surface of roofing material. Somebody widely knew this as ‘presents’ because it seems like a gift collected by Cotswold’s inhabitants. There is a ‘Pendle,’ which is a quarried tile-stone. It is subjected to frost action to split it. Then, during the winter, the stone is laid in the open. Due to this, the moisture in the saturated stone would freeze, which would expand and split the stone along the lamination. It produces the required stone of a suitable thickness for roofs. The stone divides along the laminations or bedding planes using a hammer and chisel in an alternative method. As people call it, the’ presents’ tend to produce thicker Cotswold roofing materials than the ‘Pendle’.
What makes them unique?
The Cotswold roof material is unique in several factors:
● The thickness of the roofing material is widely appealing as it provides a robust feel.
● The curvature of the roof.
● Layers of the roof make them unique as they provide extra protection as well as an overall charm.
● The roofing material comes in different colors such as off-white, brick red, forest green, and navy blue. However, there are multi-hues with brick-red and forest-green varieties, which is a mix creating an effect akin to autumn leaves.
Such roofing materials’ durability might be about 180 to 200 years; however, 100 years is more likely. Cotswold homes have a higher value in the market as more homeowners have chosen to convert their exteriors with the Cotswold designs reminiscent. They are complete with the thick, wavy shingles that provide an aesthetic look to the house.
