Slate Repair Hallhook - Pack of 10 Slate Hall Hook and 1 HookPull

Product Information

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) 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. Ventilation is also important. Roof space ventilation is the most effective and economic method of keeping harmful condensation to a minimum, and it can be achieved by providing eaves through to the ridge ventilation. Ventilation also depends on the construction method used, that can be ‘cold roof’ or ‘warm roof’. A warm roof has the insulation at rafter level whereas a cold roof has insulation at the ceiling level. 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.

The new standard for calculating fixing specifications for roof slates and slate cladding facades came into effect on 28 th February 2015. In the UK, in southern England the most common slate size is 500mm x 250mm, while in the north of England and Scotland it is 400mm x 250mm. The method of using stainless steel point slate hooks is very cost effective which is why it’s an increasingly popular choice in the United Kingdom as well as across Europe. Because the slate is supported at four different points, these hooks can be used in even the most exposed locations without sacrificing resistance to wind uplift. Once installed, natural roofing slate is subject to the forces of nature in which light, rain, ice, wind, hail, pollution and other atmospheric agents test its properties. It is vital that the slate quarried meets the rigours of these elements, so the whole production process has tobe carefully managed and stringent quality control measures need to be in place.

Features & Benefits: 100mm Bright Stainless Slate Hooks Point Driven - 316 Grade (Box of 500)

Each slate is held in place by four slate hooks – one at the head, one at the tail, and one on each side. The one at the tail prevents the hook from sliding down, the side hooks stop it from turning, and the one at the head holds it at the batten. Hall Hook slate repair fixings are the market leading remedial repair hook, designed over a 20 year period by an experienced slating contractor who always wanted to have the perfect solution to an everyday roofing problem.

The barcode also provides information about where and when the slate was processed and who worked on that particular batch. Production standards One of the most important changes is the mechanical fixing requirement of slates, increasing the safety on roofing and facade cladding. All slates must be mechanically fixed, installing dry ridge and hip systems. Mortar should be used in very traditional roofing and can be used in conjunction with mechanical fix options such as clips, nails or screws. So after experimenting with all manners of ideas and devices, Jimmy solved the slate roof repair problem with the invention of the Hallhook. Wherever possible, machine holing is preferable. Holing by hand should only be considered when a small amount of slates need re-holing for repairs or when a hole needs to be repositioned in-situ.

There are a number of advantages and disadvantages which one should consider before using natural slate. On the plus side, natural slate has an aesthetic appeal and will stay looking good for many years. As such it may not need replacing. Other types of roofing slates such as concrete will lose colour and not wear so well visually, making slate more cost effective. 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.

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 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). SolarRoof Pro is designed for optimal heat dissipation. It sounds counter-intuitive but solar panels like to run cool, power output will fall off above 25°C. This is why we prefer “on-roof “ to “in-roof” mounting. SolarRoof Pro is designed to allow cooling airflow around the PV modules to keep them at optimum efficiency. The head of the slate should lay approximately halfway on to the batten (i.e. 25mm on to the batten) leaving 25mm to nail into. A clearance of 6–12mm is recommended. In general any area within 30 miles of a west facing coastline is considered to be one of severe exposure.Clenergy provides a 10-year product warranty for your peace of mind.
