The Project

The aim of the project was to deliver a full pitched and flat roofing solution for Romilly Primary School, which was old, had been damaged by high winds and thieves had stripped most of the lead from the roof. As a result the roof compromised the safety of the children in the school and was failing in places.

Integrate the pitched and flat roofs and create a solution that is in keeping with the existing architecture, is low maintenance, theft resistant and quick to install.

For Vale of Glamorgan Council construction consultant, Paul Hynam it was important that the new roof was secure, blended with the existing roof, and was quick to install, so it could be completed during the holidays.

Cambrian works well in exposed situations and it was installed using a dry system, with fixings on the ridge and hip system to imitate the previous roof. A BMI Icopal Universal® Single-ply was used as part of the flat roof system, it is UV resistant and tough, but also light and malleable, making it ideal for details. To boost thermal performance. BMI Thermazone insulation was specified and to deal with the interface between the pitched and flat roofs,
the waterproofing was taken under the slates and up to the top of the eaves batten.


Now Vale of Glamorgan Council can have peace of mind for years to come thanks to the fully comprehensive solution offered by BMI.

“I chose BMI UK & Ireland because they offered a solution that met the brief, and provided support throughout the project,”

“Using BMI’s pitched and flat roofing products together gives confidence that both parts of the roof integrate – due to the collaborative details – and the result meets the required performance and reliability and is aesthetically pleasing. As Redland and Icopal are now one company they are able to take full responsibility for the design of construction details to ensure that they worked together.”

“Using their design service gives you a 15-year guarantee complete with on-site supervision – so you know that the roof has gone on correctly. In effect you can forget about the roof and maintenance for 15 years. BMI Redland’s Cambrian Slate also met our environmental criteria – it’s recycled – and it’s Welsh”

Recycled Natural Slate Interlocking Tiles

Recycled Natural Slate Interlocking Tiles

With the appearance of natural slate plus the added benefits of precision engineering and modern manufacturing techniques, the BMI Cambrian Slate is a fantastic choice for a slate roof that can be installed on pitches as low as 15°. The tiles are manufactured in Wales, and contain up to 60% recycled Welsh slate, meaning they weather just like natural slate.
