Since its introduction onto the UK market in 1989, the Ondutile system has been continually developed to become the market leading independent secondary weatherproof roof underlay system for low pitch tile, slate and shingle applications.
Ondutile provides the same durable weathering performance whilst reducing the roof section making it ideal for projects where height restriction or the aesthetic appearance of the roof line is of paramount importance.
