Planning & preparation
- 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
Roof deckRoofing shingle tiles must be laid on a roof deck fixed in accordance with relevant British Standards & Codes of Practice
Minimum roof slope: 12.5°
Minimum deck thickness 12mm
Shingles can be laid over existing roofing felt however, the surface must be both flat and in good condition
UnderlayRoofing felt underlay must be used on roof slopes below 20° / 1 in 5 gradient
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 10cm centres
Fix shinglesFinally fix the roofing shingle tiles in accordance with the instructions set out below
Note: Any irregularity in the surface of the decking will become visible through the shingle strips once laid
NoteIf shingles are laid on roof slopes greater than 45°, fix a second row of 5 nails per strip at the top edge of the shingle strip. This allows them to be used for vertical wall cladding applications.
- The covering of roofs can be hazardous. Always work from a secure ladder or platform and use the appropriate safety equipment.
