If the roof includes eaves, a 2-piece set is used, known as over and under eaves. The use of these pieces is complemented by the application of eave corners, should the roof contemplate them.

Before laying the pieces, verify whether lateral tile spacing (tile gap), i.e., the distance between the axis of two tile curves is equal to the distance between the axis of over eaves, as shown by the following picture:


Eave pieces (under and over eaves) are placed on the cymatium, with mortar. When laying these pieces it is essential that: 

  • The inclination of the pieces in relation to the horizontal plane of the roof should be of at least 4%.
  • Free piece dimensions, i.e., those not placed on the cymatium should occupy a maximum of 2/3 of the eave.
  • Ventilation orifices are cone to allow ventilation of the eaves, as shown in the pictures below.
