Cut roofing felt into two equal lengths. Place one length over the roof. At the front, back and along the lower edge of the roof leave an overhang of felt of at least 40mm.
Fold down the felt along the lower edge and secure to the felt batten using 20 x 10mm felt nails evenly spaced. Dress the felt over the roof ridge, tension and secure along
the edge using 4 x 10mm felt nails. position the second piece of felt in the same way as the first on the other side of the roof, ensure it overlaps the first. Attach to the felt
batten using 20 x 10mm felt nails, tension over the roof and secure with 20 x 10mm felt nails. At each end dress down the felt and secure to the panels using 8
x 10mm felt nails per end. Using a sharp knife trim off excess felt.
