SERVICES
Roof over roof
Temporary roof systems for construction, refurbishment and maintenance, planned around your site and weather protection requirements.
Weather protection
Keder Roof XL roof over roof
Layher Keder Roof XL provides temporary weather protection above construction and refurbishment work. The roof layout and supporting scaffold are selected to suit the building, work area and site conditions.

System
Keder Roof XL system
Keder Roof XL uses lightweight aluminium beams with integrated tracks for the roof sheeting. The temporary covering helps protect the work area and materials from the weather.
The aluminium construction keeps the overall weight low, making installation and relocation efficient while maintaining the structural integrity needed for exposed and elevated positions.

Applications
Where roof over roof is used
Temporary roofing can help reduce weather disruption on construction, infrastructure and event projects. Suitability depends on the design, site conditions and agreed working limits.
- Roofing during new-build construction and additional storeys
- Timber roof repairs and decking replacement
- Weather protection for new construction and fit-out
- Renovation and maintenance work on motorways and bridges
- Event and temporary structure coverage

Capability
Designed around your site
The required span, roof shape, support arrangement and local wind and snow loads are reviewed for each project. Dimensions and operating limits are confirmed through the temporary works design.
The system integrates with Layher scaffolding, allowing it to be mounted on the supporting structure and adjusted to suit the specific geometry of each project.
