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. 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. 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.
Product inventor Jimmy Hall, a slater and tiler for the past 45 years, couldn’t stand to see a beautiful slate roof covered in unsightly lead or copper straps. He had tried all the slate repairs on the market. 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)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 If your roof has slates that have slipped or twisted out of position, the slate can simply be reattached using a tingle and fixing nail as above. 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.
Water damage to ceilings. This can indicate that there’s a problem with your roof. Just be aware that the damaged roof tiles are unlikely to be directly above the damp patch on your ceiling 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 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.
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. If your slate roof has been poorly installed, this can also lead to issues. For instance, if your roofer uses nails that are too thin, these can slowly cut through the roof slates. Poor quality slates If you only need to repair a small area of your slate roof, we offer the Hall hook slate repair fixings kit. The Hall hook will leave you with a professional, neat repair that is fail-safe and invisible once complete. Unlike many slate repair methods and plastic alternatives, these hooks are durable, time-efficient, and the perfect answer to everyday roofing problems. Copper Slate Straps Manufactured from various grades of stainless steel, the slate hooks are available in two sizes – 80 mm and 100 mm – and come in boxes of 500. Fixing a roof involves working at height. So, it’s a dangerous job that you shouldn’t undertake without the right experience. It’s also important to note that if the work isn’t completed correctly, it could lead to costly problems later down the line – or you could even end up damaging the surrounding slate roof tiles.
Fixing clips and roof slate hooks are typically made from durable materials such as stainless steel or galvanized steel, and come in a range of sizes and styles to accommodate different tile and slate shapes and configurations. Roof tile fixing products, such as fixing clips and roof slate hooks, are essential components in the installation and maintenance of tiled and slate roofs. Fixing clips are designed to secure tiles in place, while roof slate hooks are designed to secure slates. These products help to prevent tiles and slates from becoming dislodged or damaged due to wind, rain, or other environmental factors. Slate tiles make a dull sound when tapped. Okay, so this one might be difficult to notice. But if you spot any loose slates, tap them square in the middle with a hammer and note the sound they make. If you hear a dull sound (as opposed to a bright ringing), it may mean the slate tiles are porous and no longer usable
