The cost of the plate itself is higher than other slate fixing solutions on the market but the positive impact it has on installation time heavily out ways the additional cost of the product itself. The 3 installations(total 25.5kW) were installed in 3 days by 2 panel fitters so a substantial saving was made on the installation costs. The benefits of this product for us are listed below:

a) The next step is to work out the placement of the battens– to do this you’ll need two full-sized slates and an under eaves slate. Place two battens onto the roof on top of the overlay – don’t fix them down so they can be moved around for adjustments easily.Typically, slate hooks attach to the batten by a spike at the upper end, which is driven into the batten or a hook that wraps around the batten. The use of wrap hooks is not recommended. Only “spike-end” or nail-in hooks are permissible under BS 5534. All natural slates can be fixed using slate hooks. The hook method offers considerable freedom in design and can save up to 25% on labour costs and eliminate breakages. The practice is very popular in Europe and is gaining popularity in the UK. Stainless Steel Slate Hooks are an alternative fixing to clout nails for fixing Natural Slates, which is used extensively across Europe. This method offers a cost effective alternative method with lots of bonuses. Hooks can be used in the most exposed locations and because the slate is supported at four points, the resistance to wind uplift is extremely effective. The top edge of the slate is gripped under the top part of the hook. The shank of the hook runs down along the side of the slates in the next course, and the return grip at the bottom of the hook holds the tail of the slate on top. This means that each slate is held in place by four hooks; one at the head, one at the tail and one on each side. The one at the tail stops the hook from sliding down, the ones at the side prevent it from turning and the one at the head holds it at the batten. If you measure from the top of one batten to the top of another, this gives you the batten gauge. This allows you to work out the distance between the battens on the rest of the roof. For example, if your roof is 500cm, and the pre-existing battens are 20cm apart, a total of 25 battens will be required, each 20cm from the previous one. 6. Lay the roof slates

Fixing SIGA slates is straightforward for an experienced slater. Most SIGA slates come pre-holed at a nominal 90mm headlap. By simply moving the location of the slate on a standard 50x25mm batten, these can be fixed to obtain headlaps between 76 and 96mm, allowing them to be used on a variety of pitches. Nailing Natural Slates With a bright stainless steel coating for a purely decorative finish, this coating does not impact the corrosion resistance of the core material. The bright finish will typically last ten years or more unless in very abrasive settings for example salted winds.Once both nails have been removed, slide the broken slate down and take it out. Now compare the broken slate with the new slate. The replacement slate needs to be exactly the same size, so trim if necessary. The Hall Hook is a permanent, secret and fail safe device that should be used when replacing a broken slate.
