Minimum Recommended Inclination

Any tile type can be used on a sloping roof. However, the maker cannot be held responsible in the case of failure to comply with the technical specifications resulting in defective performance.

When roof inclination is lower than recommended, supplementary insulation elements should be used to guarantee the roofing work is properly watertight.

The values above are applicable to roofing work executed without inner lining. For roofing work with lining, these values can be reduced by 1/7 (ref. DTU 40.21).
