Bridge Cottage in Devon, featuring Cembrit's Duquesa natural grey slates

Duquesa slates installed on 17th century listed building

  • 7 Sep 2015

Cembrit’s Duquesa slates have been installed on a sensitive re-roofing project in Axminster, Devon, which involved the refurbishment of a listed 17th century building.

Originally built as a labourer’s cottage, and constructed as a low cost building, Bridge Cottage has required a series of upgrades over the years, including new windows, a garden room and covered parking bays.

Most recently, its owners made a request to East Devon District Council to re-roof the property and specified slates to match the roof on an extension. 

Bradford’s Building Supplies supplied approximately 4,500 Cembrit Duquesa natural slates, which were installed over an existing corrugated steel roof that had been in place for between 60 to 70 years.

As the roof is not at a consistent level, the slates had to be flexible enough to deal with a change in pitch – from 45 degrees at one end, to 60 degrees at the other.

The dark grey Duquesa slates maintained a uniform appearance across the whole building, complementing the lighter grey slate on the extension. The Duquesa slate’s smooth surface texture blended with the aged appearance of the cottage, to give it a contemporary yet natural-looking finish.

Lifelong guarantee

Duquesa is a natural slate from Cembrit which is produced by some of the most highly regarded quarries in Spain. It is a tough material with a smooth texture, designed to provide an attractive and long lasting roof covering for a wide variety of applications.

Duquesa is available in two colours, blue black and grey and in a variety of sizes to suit individual requirements. 

Its hard surface ensures that the slate can withstand the most severe weather conditions and remain unaffected by sunlight, ultraviolet light and acid rain. Moreover, its smooth texture aids the preservation of the finish.

When laid correctly, Duquesa is intended to last the lifetime of the building, ideal for use on major projects including supermarkets, schools, offices and prestige homes.

The slate has been tested to ensure it meets the current national standard, BS EN 12326-1:2004, which requires detailed and regular testing of the output from every source marketed within the EU.
