Ridge Course Nailing & Lapping D Ridges
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. 

D Ridge Ends Caps
 
1. Snip and fold out flap to suit choice of verge/barge cover.
2. Trim edge of flap to create a vertical plumbline 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).
