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: After receiving an instruction to proceed with a 33.35kW solar PV installation upon 4 roofs of a private estate, we wanted to find a more cost effective solution for installing the mounting system to the 3 slate roofs in the project.

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. 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. 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).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.

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

Take a strip of lead and nail it into place against the batten, then push the replacement slate up and into position, ensuring it is level with the other slates. 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. 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.

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 Hall Hook is a permanent, secret and fail safe device that should be used when replacing a broken slate. Fixing with a slate hook involves trimming the head of the slate, thereby losing some head lap (a building inspector may not accept this) 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.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. Suitable for fixing roofing slates on a roof application, these slate hooks are an ideal alternative to the copper nail. Manufactured from 316-grade stainless steel, these hooks are guaranteed in severe coastal exposure conditions in front of the sea or industrial environments.
