Product Information

c) Next, put the second batten underneath the slate, and slide it upwards towards the first batten. Take the eaves slate and position it onto the second batten, ensuring it reaches the bottom of the roofline. The man-made roof slate is considered more eco-friendly for consumers. However, despite their development process taking a more modern approach, their look doesn’t steer far from the traditional slate appearance. Due to their manufacturing, they also have a greatly reduced risk of breaking. Recycled roof slate

The British Standard Code of Practice (BS 5534) specifies two ways of installing slates: nailing or hook fixing. These fasteners fix the slates to either batten, which is by far the most common English method, or to sarking board, which is commonly used in exposed areas in Scotland. There are two type of Slate Hook, an over batten type and a drive in type. The use of over batten type is very limited with the majority being drive in type (shown in picture).

Now fold the lead strip over the bottom of the replacement slate to keep it in place, acting like a hook. This should hold the replacement slate securely in place. In centre-nailed slating, the gauge is the spacing at which the battens are fixed to the rafters, trusses or counter-battens to provide the required head-lap. The margin is the exposed length of the slate measured in the same direction as the gauge. The lap and margin will be the same.

Electro-galvanized steel will eventually rust and will not last as long as stainless steel, but is a good choice for asbestos-shingle roofs or for a roof with around 25 years of life remaining. Firstly, ensure your rafters or trusses are clean of any splinters or old nails that could damage the membrane. Then roll your chosen roofing membrane along the roof trusses – start from one bottom corner and roll it along to the other corner. These hooks are frequently used when replacing individual slates or making minor repairs on a roof. The length of hooks required is equivalent to the head lap plus 2-3mm. Features & Benefits: 100mm Bright Stainless Slate Hooks Point Driven - 316 Grade (Box of 500) Now the roof has been set out correctly, with the battens at the right distance apart, it’s time to lay the slates. Start by laying the under eaves course, creating a staggered pattern for stability – a 5mm gap between each slate is required to allow for natural expansion.

With the hook fixing system, the slates are secured at the tail, thus providing strong resistance to wind uplift. To comply with BS 5534, hooks should be stainless steel, 18/10 or 316 (marine) grade, 2.7 mm gauge and at least 5 mm longer than the minimum lap required.

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. 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 Some metal fixings are flimsy. Others take too much time, are awkward to prepare, and if wrongly prepared the head of the slate could slip off the upper batten.Centre-nailed, double-lap slates are fixed with two nails close to the side-edge of the slate and positioned immediately above the slates below. Roof slates are a very popular choice when it comes to deciding which roofing material to use on a pitched roof. As well as being aesthetically pleasing, and increasing the potential selling value of the house, roof slates have a number of physical benefits. Slate is a durable and hard-wearing material that provides waterproofing characteristics to a pitched roof, unlike other roof materials which absorb water. This means that slate is unaffected by frost damage and freezing. What types of slate roof are there?

The natural roof slate is exactly what you’d expect. This authentic slate roof solution provides the ultimate natural slate look and comes with an array of benefits. Not only does it look great, but it is also fireproof, frost resistant and requires little maintenance. It also comes in a variety of different styles including Spanish slate (below), Welsh slate, Canadian slate, Brazilian slate and Argentinian slate. Man-made roof slate Nails should be copper (to BS 1202 part 2) or aluminium (to BS 1202 part 3). In corrosive or marine atmospheres copper nails are preferable and in severe conditions silicone bronze nails should be used. The nail head diameter should be at least 10mm to comply with BS 5534 to minimise the risk of the nail head pulling through the slate. A 10mm head is only possible where the nail shank is 3mm diameter or greater. If you are looking for a cost-effective alternative to copper nails yet still comply with British Standard, alloy clout nails are an excellent choice. These nails have been specifically manufactured for use on natural slate roofs and will protect your roof from nail fatigue. Stainless Steel Slate Hooks

When hook fixing, additional nail fixings should be used at eaves, ridges and top abutments and, to prevent lateral drift, at verges, hips, valleys and side abutments. Firstly, put the hooked end of the slate ripper underneath the damaged slate, trapping the nail in the hook. Then hammer the handle of the slate ripper, to force the nail out of place.
