The Torreense Marselha tile is a fitting roof tile that can be laid in two ways, as shown in the picture below.

marselha-cruzado-alinhado

Both options are equally valid and the choice is merely aesthetic. If choosing cross laying, the tiles should be “cut” as depicted.

The Torreense Marselha tile should be laid according to the following scheme:

marselha-assentamento

The picture above shows the proper way to lay the tiles, allowing for slight adjustments while providing an overall view of how the roofing work will be conducted (applying the tiles from right to left and from bottom up). Applying the tiles this way will facilitate the alignment of several rows as the roof takes shape.

It should be noted that in slopes above 150% and/or exposed to strong winds, the roof tiles should be fixated to the lath work, at a proportion of 1 tile in 4. If the slope has values above 300%, all tiles must be fixated.
