by 55mm. Secure each panel to the roof purlins and the top frame of the side walls using 6 x 35mm screws per panel. Working towards the front of the building, hook the
centre roof panels over the upper purlins and with them pushed right up against the rear roof panels, secure each panel with 6 x 35mm screws. Add the front roof panel and
secure in the same way. To the inside of the roof fit the apex cover to the two centre purlin using 6 x 35mm screws.

8. Roofing felt
Place a length of felt over half of the roof. At the front and along the lower edge of the roof leave an overhang of felt of at least 45mm to cover the felt battens. Fold down
the felt along the lower edge and secure to the felt batten using 30 x 10mm felt nails evenly spaced. Tension the felt over the roof and secure along the upper edge using
6 x 10mm felt nails. Repeat this for the second piece of felt on the other half of the roof. Once the two pieces of felt are in place take the 3rd felt piece and place over the
apex of the roof making sure it sits centrally over the roof ridge and overlaps the other two felt pieces, attach using 30 x 10mm felt nails evenly spaced, along the two long
edges of the ridge felt. Dress down the ends of the felt and at the front attach to the felt batten with 6 x 10mm felt nails. Repeat at the back of the building. Once secured
trim off excess felt.
