Sold in bundles. One bundle contains 36 pieces, 18 right hand and 18 left hand mitres. These are fixed alternately at the same gauge as the roof.
Ridges
1. Trim shingles to size to create shortened ridge course. Lay along twice length of ridge, fixing each shingle twice.
2. Using pre-formed ridge units, lay along the ridge, ensuring a minimum overlap equal to the shingle guage on the roof covering. Ridge units should be twice nailed, once either side of the ridge line.
Hips and Ridges
To speed up and simplify installation, use pre-formed hips and ridges.
When installing, start at each edge and work towards the middle.
