INSTALLATION OF FIXING BARS INTO
ROOF
1. Lay the roofing underlay working from bottom
right to top left of roof slope. Tack the underlay
into the first rafter at right hand side of roof.
2. Roll the roofing underlay out across the rafters
taking care to create an approx. 10mm drape
between rafters.
3. Finish the roofing underlay at the left hand side
of the roof and tack into final rafter at left hand
side of roof to secure the underlay.
4. Set out the tiling battens in the normal way
(gauge determined from maximum batten
gauge for roof tile selected and the distance
between top of the eaves course batten and top
of the top course batten near the ridge).
Check
table at “6” to ensure that gauge is suitable ,
and adjust gauge if required.
5. Ensure the tiling battens are fixed into the
intersection of each rafter with the correct
batten nail fixing (Note: The correct batten fixing
depends on the roof construction and location.
Redland
Technical Solutions should be
contacted for the correct fixing specification for
both the tiling battens and the roof tiles).
