Onduline launches new INNOLINE installation guide
18 August 2026Onduline has launched an installation guide for its new roofing system INNOLINE, providing DIYers with practical advice and guidance to help them achieve a professional-looking finish when roofing sheds, garden offices and other outdoor buildings.
Installation guidance
Launched this year, INNOLINE is a lightweight roofing system developed specifically with DIY installation in mind. Featuring an attractive tile-style finish, the system combines durable performance with a modern aesthetic and is backed by a 20-year waterproofing guarantee.
The new guide supports users throughout their roofing project, from initial planning and calculating the quantity of materials required through to preparing the roof, positioning and fixing the sheets, and installing the verge and ridge components.
Designed to make installation as straightforward as possible, INNOLINE requires no specialist tools, with only a drill and tape measure needed and a standard saw optional. The lightweight 2kg sheets can be installed by one person, while their overlaps can be adjusted to suit the dimensions of the roof, helping users to complete many installations without having to cut the sheets.
The guide also provides clear advice on the requirements users need to consider before starting a project. INNOLINE is suitable for roof pitches from 9° and must be installed onto a solid, continuous deck such as OSB or plywood. Applications include sheds, garages, barns, gazebos, pergolas, stables, garden offices and other leisure or storage buildings.
Complete system
Alongside illustrated installation instructions, the guide includes product quantity estimates for different roof sizes, guidance on the correct positioning and fixing of sheets, and advice for completing verges and ridges. It also covers more advanced applications, including wall junctions and changes in roof slope.
INNOLINE features Onduline's Compact Core Technology, a manufacturing process that compresses high-quality fibres to create a dense and uniform core structure, improving rigidity and helping the sheets maintain their performance over time. The complete INNOLINE® system comprises roofing tiles, ridges, verges and Onduline screws and is available in Black, Sienna (Terracotta) and Anthracite Grey.
