For new build projects just follow the information contained in this leaflet
to create a long lasting trouble free shingle tile strip roof covering
For an existing roof; survey your roof structure, this will allow you to
decide if it requires maintenance, upgrading or strengthening prior to
fixing the shingles. Make a note of the roof construction; you require
a decked roof fixed to rafters or supported on a trussed roof structure
You will need to measure the slope of your roof. To do this, simply
measure the angle of your roof with a protractor. Then select one of the
three options detailed below that best matches the slope of your roof
Do it right
Roofing shingle tiles must be laid
on a roof deck fixed in accordance
with relevant British Standards &
Codes of Practice
Minimum roof slope: 12.5º
Minimum deck thickness 12mm
Shingles can be laid over existing
roofing felt however, the surface must
be both flat and in good condition
Roofing felt underlay must be used
on roof slopes below 20º / 1 in 5
Indeed it’s good practice to always
use a roofing underlay below shingles
Roofing felt underlay should be laid
on the roof with 15cm end laps and
fixed by nailing with 10mm large
headed galvanised clout nails at
Finally fix the roofing shingle
tiles in accordance with the
instructions set out overleaf
Note: Any irregularity in the surface
of the decking will become visible
through the shingle strips once laid.
The covering of roofs can be hazardous. Always work from a secure
ladder or platform and use the appropriate safety equipment
Position and unroll the detail strip square to the line of the eaves. Fix by
nailing top edge of detail strip using 10mm galvanised clout nails. Form the
drip edge either dressing into gutter; or nailing to fascia at 5cm centres.
Ensure the shingles are positioned square to the line of the eaves and verge.
Horizontal shingle tile alignment is created by Interlocking side slots to the
edges of the shingles. Vertical shingle tile alignment is created by opening
guide slots in the top of the shingle strip into which the next course is engaged.
Overlay the detail strip at the eaves with the base course of shingles nailed
using 20mm galvanised clout nails, applied in line with the tile tab joint just
above the bitumen adhesive strip. (5 fixings per strip)
The fixing of the eaves course of
roofing tile shingles is completed
by applying felt lap adhesive onto
the detail strip below the tile tabs
to secure them to the detail strip.
Lay the shingles diagonally across
the roof taking care to keep them
square to the line of the eaves and
verge. Start shingle tile course with cut
lengths to form a broken bond patten.
First prepare the joint by cleaning
off roof debris. Lift the tile tab and
heat the bitumen adhesive strip
on the lower course with a high
performance hot air gun.
Press the tile tab down with a
batten. Check the bond after
cooling and apply gun applied felt
lap adhesive if so required.
Apply felt lap adhesive onto the detail strip, then overlay the roofing tile
shingles cut to the verge edge. Nail the shingles centre line at verge to fully
secure shingles in place.
Mark out and unroll the detail strip along the ridge line secure by nailing edge
at 10cm centres using 20mm galvanised clout nails. On exposed sites apply
felt lap adhesive as required.
Cut shingles with knife against a deep sided spirit level / batten to protect
fingers should the blade slip. Always mark out and cut the underside of the
shingle to reduce wear on the knife blade.
As an alternative to using detail strip for the ridge detail you can produce
shingle ridge tiles from roofing tile shingle strips, creating an attractive tile finish
to your building. See ‘Fitting shingle ridge tile to roof’.
Fitting shingle ridge tile to roof
The ridge tiles are positioned on the roof and nailed through the lapped
section using 20mm large headed galvanised clout nails.
The bitumen strip is then heated and the joint consolidated with pressure
from a batten. On exposed locations reinforce the tile lap bonding with felt lap
adhesive applied in a continuous bead as required 2.5cm from edge of tile.
