Roof Felting
9
Lay the first piece of roof felt onto the ply roof, this should have about 50mm overhang at the
bottom of the roof. Using the clout nails provided fix the sheet to the roof. When nailing you should
position the nail no more than 20mm from the joint in the ply sheets so the nail goes into the roof
bar. The nails should also be no more than 300mm apart (diagram 44).
It’s a good idea to check inside the building as you go incase there are any mis-placed nails that need
re-positioning.

Work clockwise around the
building until all the felt
sheets are in place.
