8. Roof felt
Cut the 4m felt roll into two equal parts. Place a length of felt over the solid part of one side of the roof. Along the lower edge of the roof leave an overhang of felt of at
least 45mm and at the end where it meets the glazed panels have the felt over lap the glazing by at least 25mm. Fold down the felt along the lower edge and secure to
the felt batten using 20 x10mm felt nails evenly spaced. Tension the felt up the roof and secure along the upper edge using 5 x 10mm felt nails. Repeat this for the second
piece of felt on the other side of the roof. Once the two pieces of felt are in place position the 2m roll of felt over the roof ridge making sure it sits centrally and overlaps
the other two felt pieces, attach using 20 x 10mm felt nails evenly spaced, along each lower edge of the piece of felt. Dress down the felt pieces at the apex end and attach
to the roof battens using 10 x 10mm felt nails. When all the felt is in fixed in position, trim of any excess.
