Onduline supports Aldi’s re-roofing programme

Burton Roofing Merchants and Onduline’s Isoline Low Line are supporting Aldi’s nationwide re-roofing programme.

As a sub-roof system, Isoline Low Line provides a secondary waterproofing layer that can accommodate a range of technical challenges, making it particularly suitable for re-roofing schemes where existing tiles needed to be reused or where long rafter lengths created vulnerability to water ingress.

During initial discussions between specifiers, architects and contractors, Burton Roofing introduced Onduline’s Isoline Low Line, which was integrated into the proposed specification and trialled at three pilot sites: Gainsborough, Barnsley, and Shirebrook.

Following positive results, Aldi approved the Isoline-based specification for full-scale national rollout.

Since the first trials, 16 re-roofing projects have now been completed using the specification, with further schemes in the pipeline.

Paul Duffy, managing director at Onduline said; “This programme is a great example of what can be achieved through early collaboration and shared ambition. By working closely with Edge, Northstone Tiles, and the wider Aldi team, we’ve supported the development of a robust and adaptable roofing specification. the Isoline Low Line system helps tackle modern-day challenges we’re seeing more often in refurbishment projects, whether it’s complex roof structures, tile reuse, or keeping buildings operational during works. It’s a privilege to see our system specified as part of such a prestigious and forward-thinking rollout.”
