To ensure adequate ventilation of the roof surface covered with tiles, special ventilators with a brush are installed under the ridge tiles.. The openwork of the brush is perfectly permeable to air, preventing birds or rodents from nesting inside gander. The ventilator is nailed to a special ridge batten attached to the rafters with holders. Individual ridge tiles are placed on the ventilator. On one side, the gander is nailed with a nail, on the other hand, it is secured with a specially bent plate.
