PROBLEM TO BE SOLVED: To secure sufficient air ventilation from indoor to a ridge and to form a roof tile ridge part excellent in an outer appearance by providing waterproofing projections on a horizontal surface having a plural number of ventilating openings, a bottom slope continuing to it and upper parts of the ventilating openings. SOLUTION: A ventilating clearance of about 30 mm is formed between roof boards to ventilate from a ridge part. A bottom slope 1b matched to a roof board inclination of a roof is provided on a ventilation drip 1 for a tile ridge, a side surface 1a is provided in the vertical direction continuously from an upper end of the bottom slope, a horizontal ventilating opening 1d is provided on the side surface upward and a waterprofing projection 1c is provided on an upper part of the ventilating opening. A pair of these ventilation drips 1 for the roof tile ridge is used on an upper part of the evntilating clearance, and a side surface upper part is set so as to make contact with a ridge piece. Consequently, it is possible to secure sufficient air ventilation without changing a ridge shape of a conventional housing. Additionally, it is possible to further perfect waterproofing by setting a ventilating member 2 for the tile ridge on a front surface of the ventilating opening 1d so that its lower side surface 2d is arranged.
