| 摘要 |
<p>The present invention relates to a ventilating roof tile (10) comprising a sloping top surface (16), a sloping bottom surface (15) substantially parallel to the top surface (16), at least one non-linear groove (11) extending from the lower edge of the sloping bottom surface (15) upwards to the upper portion of the sloping bottom' surface. The ventilating roof tile is laid to be partially on top of any other roof tile (20) to create a tortuous passageway (A) at the lower portion of the groove (11) and an uncovered inverted channel (B) on the higher portion of the groove. A ventilating roof system is thereby formed using said ventilating roof tiles alone or in combination with other non- ventilating roof tiles.</p> |
