Stainless Steel Roof Bolts
1.
Undo the nuts on the back of the manifold and assemble the frame (it shouldn't use
washers), then offer this up to the roof and mark the top and bottom slots on the frame
on to the tiles using chalk or a drill etc... Try to catch the rafter on one side - it makes it
easier.
2.
Drill 10-12mm holes using a bit without hammer. Go inside and make up noggins to line
up with the holes that are not in line with the rafters (you will see the holes very clearly).
3.
Back on the roof, drill pilot holes into the wood, drilling through your holes in the tiles
using a 6-8mm bit.
4.
Wind in the bolts using an adjustable spanner so that the frame sits level with the roof,
clamped between the top pair of nuts/washers. The lower nut/washer tightens the EPDM
washer to the roof tile.
Please note that you have the new thicker roof bolts so you will need to widen the top and
bottom slots in the frame using a file or a drill (not difficult, the frames are only 1.2mm stainless
steel) in order to take the roof bolts without damaging the thread.
