Slopes of tile roofs

The minimum slopes for interlocking or gliding clay tile roofs are as follows (see paragraphs 1, 6 and 7 of the fascicule) ) :

• type of tile: raised or flat;

• Tile format: large mould or small mould;

• the area of application and the location of the building;

• the presence or absence of an underlayment.

Minimum roofing slopes based on the above data are specified in tables 1, 2 and 3. These tables are valid for slopes whose length does not exceed 12 m in horizontal projection.
