Cut top tiles to suit (leaving a 10mm gap between the top cut edge of the tile and the top cut edge of the tile on the other side of the ridgeline).

The ridge caps have a slight taper in their design. Place the wider end of the ridge over the narrower end of the ridge beneath creating an 80mm overlap.
Each ridge should be secured with 4 nails on each side of the ridge cap.

NOTE: Where roof pitches exceed 35° it may be necessary to adjust the return angle of the downturned leg of the ‘D’ Ridge Cap.

  2. Trim edge of flap to create a vertical plumb line when fitted.
  3. Install D Ridges over end of D Ridge End Cap ensuring good tight lap occurs. Then nail D Ridge End Cap into position (Fix vertical end of D Ridge End Cap first).
