Using hexagonal shingles is similar, but differences arise because unlike the Square Butt Shingles. Hexagonal Roofing Shingles have an adhesive surface on the reverse of each tab, protected by removable film. Prepare your roof deck with underlay as detailed for Square Butt Roofing Shingles. Creating the "verge-edging" pieces means cutting off the hexagonal tabs from the shingle strip and removing the release film. When positioning the verge edging piece, it is again important to allow a 50mm overhang at all edges. Remember to use a full shingle, turned with the tabs facing up the roof, overhanging the roof edge by 50mm. At joints between individual shingles strips, use one of the 3 hexagonal tabs (that has been cut off when you made the verge edging) as a soaker piece as shown in Fig.7. |

Folding the Eaves Roofing Shingles
Now gently fold the verge pieces over the roof edge, taking care to warm the shingles in cold conditions. As shown correctly position the eaves shingles, gently fold over the roof edge and nail in position, cutting the corner details allowing overlaps to be folded around corners before nailing into position. |

Removal of
the release backing Before applying any Hexagonal Roofing Shingles always remove the release sheet backing to expose the heat activated adhesive coating. But do not remove the backing until you are ready to fix the shingle |

Alignment of the first shingles course In order to position and fix the first shingles course, trim125mm from the verge tab of the first shingles course. Repeat this for all odd numbered courses. Set out the position for the first shingles course so that the edge of the shingle strip is aligned 5mm from the edge of the roof. Ensure that the single cut-out of the first shingle course aligns with the reversed shingle tab from the eaves shingle strip. Position and fix the higher roofing shingles courses.
Next position and fix subsequent courses.
For the second course,
continue with the full shingles strips for the rest of the course.
Use whole shingles for the second and all even numbered courses. For
normal fixing, shingles should be nailed 25mm in from each edge and
above each cut-out, along a line 25mm above the cut-outs. Use Lap Mastic or Roofing Felt Adhesive to cover the nail heads of individual fixing points and in the corner of each tab, for added security in exposed locations, prior to heat activation of the tab coating. Finally to finish the roof edge capping, the ridge shingles must be cut from the shingle strips, inline with the centre of the cut-outs. Three ridge shingles can be cut from each Hexagonal Shingle strip. These ridge shingles should be nailed both sides of the ridge apex and nail fixings covered by the next. The Completed Job
