Changes to the British Standard code of practice for slating and tiling, BS 5534, have paved the way for Redland’s latest system, the Rapid Verge and Ambi-Dry Verge for Redland 49 tiles and Fenland Pantiles.
This is the first dry verge on the market created specifically for use with these tiles.
Perimeter roof tiles on all roofing projects are now required to be double-fixed and the dry verge solution not only provides a mortar-free verge but also a secondary mechanical fixing for perimeter tiles at the verge helping to comply with BS 5534.
Making installation even easier, the ambidextrous dry verge systems are easily adapted on site to fit either the left or right hand verges of the roof, meaning only one verge unit is required rather than two.
With a very simple installation process, the verge is supplied in packs of 10 units containing everything required for a neat and secure fixing, including Batten End Clips and stainless steel nails. A dry verge system that fits both the right and left hand side of the roof is also available for all other Redland interlocking concrete tiles.
Step 1: Battening/setting out
Install the underlay according to the manufacturer’s specifications. Extend the tiling battens 45mm beyond the bargeboard, brickwork or gable ladder. Ensure all battens project by the same distance to ensure a straight verge line.
Step 2: Install the batten end clips
Using the 20×2.65mm nails provided, fix a batten end clip to the end of each tile batten to provide a secure fixing for the verge units.
Step 3: Eaves closure
Fit the eaves closure unit over the first tile in the eaves course. The eaves closure unit both prevents birds and water getting into the roof while also providing the fixing position for the eaves clip.
Step 4: Eaves closure – fixing to the bargeboard
Fix into the bargeboard through the two most appropriate holes in the eaves closure unit using the two screws provided. It is also possible to fix the eaves closure unit to the fascia board with the ‘L’ shaped clip provided.
Step 5: Preparing the verge unit
Depending on whether needed for the left or right hand verge of the roof, prepare the rapid verge units by snapping out the relevant tab as marked.
Step 6: Laying the verge – first unit
Clip the first rapid verge unit over the eaves closure unit. Slide the rapid verge in the direction of the ridge until the tail of the unit lines up with the tail of the roof tile.
Step 7: Securing the verge
Ensuring contact with the tail of the tile, nail the head of the rapid verge unit into the batten end clip secured to the first tiling batten. Nail through the most convenient hole in the grid using the 65×3.35mm ring-shanked nail provided.
Step 8: Laying the verge
Carefully position the second rapid verge unit in the upper and lower slots of the first unit. Slide the rapid verge unit, ensuring the upper and lower lugs are securely engaged, in the direction of the ridge until the tail of the unit lines up with the tail of the roof tile. Secure the head of the second rapid verge unit to the batten end clip as before. Continue in the same manner up the entire length of the verge to the ridge.
Step 9: Top course
Click a ridge comb unit onto the top of the ultimate rapid verge unit. The ridge comb prevents bids and large insects entering the roof. Slide the ultimate rapid verge unit in the direction of the ridge until the tail of the unit coincides with the tail of the roof tile as before.
Step 10: Completion
Repeat the same steps for the verge on the other side of the ridge ensuring the ridge combs attached to the ultimate verge units on both sides of the roof interlock correctly at the apex. Finish the ridge off with either a block end ridge or a ridge end cap.
