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

Product Information

SolarRoof Pro only uses high-grade anodized aluminium and stainless-steel components to international standards. Strict quality control over materials and finished products ensures optimum strength and long life for your installations. The exposure grading varies depending on the area and can be identified via the annual driving rain index. Type of slate 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.

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.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. 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. The geographical and geological characteristics of the quarry the slate is extracted from will determine its composition and other characteristics, including its surface texture and appearance. Certain constituents such as iron or copper pyrites can have an adverse effect on the appearance and integrity of natural slate over time.

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) 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.So after experimenting with all manners of ideas and devices, Jimmy solved the slate roof repair problem with the invention of the Hallhook. Fixing with a slate hook involves trimming the head of the slate, thereby losing some head lap (a building inspector may not accept this) 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. 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. The location is important as well, as it will impact the exposure. For example, buildings positioned on slopes, hills or coastal areas are classified as high exposure.

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. The type of slate used depends on the pitch of the roof. For example, small slates are more suitable for steep roofs with free-flowing drainage whereas larger slates are a better choice for lower roof pitches with more exposure. 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. In the UK under BS EN 12326-1:2014 a hundred samples are selected by the company commissioning the test. 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.

Centre nailed slates

The new standard for calculating fixing specifications for roof slates and slate cladding facades came into effect on 28 th February 2015. 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.
