BMI Redland Rosemary Delivers Restoration in Robust Conditions

COMBINING A HERITAGE appearance with 21st century performance, the BMI Redland Rosemary Clay Classic tile, proved ideal when sensitivities surrounding conservation and heritage environments were paramount.

When architect Gordon Delgano wanted to refurbish his mid-terrace house in an architecturally distinguished area of Glasgow, it was to the Rosemary Clay Classic tile he turned. As Gordon says: “The tiles were originally Rosemary and directly fixed to timber sarking. After more than 80 years, some tiles were slipping due to nail fatigue, so it was time to consider replacing. And I really wanted to replace it like for like.”

Together with Mark Cattanach of Rooftec (Scotland), he chose tiles in Light Mixed Brindle, having used them on a separate garage and kitchen extension in 2001. Built in 1936, the three-bedroom house in Beechwood Drive overlooks the city and so enjoys an excellent outlook. Yet it is fully exposed to the force of the prevailing south-westerly winds.

“I knew from this that it would weather well and blend in with the surrounding area, which is important,” Gordon says. “The method of fixing is also very robust. The tiles are nailed onto cross battening that is so dense and close that the roof looked as if it was yellow before the tiles were laid.”

Robust and ideal

Mark also installed the BMI DryVent Ridge system with half-round ridge tiles to meet the current British Standards and fitted Code 5 lead for the valleys, skews, aprons and abutment. Mark comments: “We prefer small format tiles because, when you’ve prepared the roof properly, it results in a stunning job at the end that is very robust and ideal for the Scottish climate.”

“These houses are designed with these tiles to achieve a particular appearance. So if they are re-roofed with a large format tile then it detracts from the character of the whole building, in my opinion.”

The first BMI Redland Rosemary plain clay tile was made back in 1838, the year of Queen Victoria’s coronation. Many of the tiles laid then are still very much in evidence on buildings around the UK. This is why contractors, architects and specifiers need contemporary versions to match.

Unlike its Victorian counterpart, the latter-day Rosemary Clay Craftsman Victorian has undergone a robust programme of testing. This includes being subjected to driving winds and high rains, by BMI’s engineers in the company’s wind tunnel. The tiles will meet all the requirements of the current BS 5534: 2014 +A2:2018 Code of Practice for Slating and Tiling. This is providing they are installed in compliance with BMI Redland’s fixing recommendations.

Suitable for pitches ranging from 35o to 90o, these tiles are often used for restoration and refurbishment projects. They can also be used for new-build developments linked to conservation areas. Particularly since there is a suite of compatible accessories and components enabling the tiles to be laid on a variety of roof configurations.

Produced from the finest clays – Etruria Marl – Rosemary is offered in a range of weathered, brindled and single colours. Complete with both smooth and sanded finishes. The BMI Redland Rosemary Clay Classic tile provides an exceptional solution to conservation and heritage restrictions. It ensures that the building continues to blend in with its modern surroundings.
