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: 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. a) The next step is to work out the placement of the battens– to do this you’ll need two full-sized slates and an under eaves slate. Place two battens onto the roof on top of the overlay – don’t fix them down so they can be moved around for adjustments easily. 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.
Aesthetics – the nails are hidden beneath the rows of slate above, whereas hook fixings are visible. Although the traditional method of slating a roof uses hooks, this can be time-consuming and complicated. Therefore, in this guide, we will be outlining how to slate a roof using pre-drilled slates.
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. So after experimenting with all manners of ideas and devices, Jimmy solved the slate roof repair problem with the invention of the Hallhook.
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 Hall Hook is a permanent, secret and fail safe device that should be used when replacing a broken slate.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.
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? 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.To replace a slate on a slate roof, you’ll require a slate ripper, tin snips, and a hammer, as well as a new slate and a strip of lead. 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. A slate roof isn’t limited to one type of slate material. Here at Roofing Superstore, you can choose from an array of unique slate solutions. Here is a brief summary of notable points regarding the types of slate available to you: Natural roof slate 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. Before starting the installation process, you need to find out the pitch of your roof. the roof pitch dictates how much overlap is required with each slate. This has been made easier with the development of technology. Most smartphones nowadays can access apps that have been designed specifically to find out the pitch or angle of your roof, such as the VELUX pitch roof app. 2. Find out the required overlap
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
Centre nailed slates
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. 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) 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. Once the membrane has been rolled out, use clout nails to secure one edge. Then pull the membrane taut at the other end, and fix it into position, before adding a few more nails across the membrane where it meets the timber trusses for extra stability. 5. Batten placement Firstly, find out if your slates are pre-holed. If they aren’t you’ll need to pierce two holes into the slate, one either side of the short width, approximately a third of the way up the length of the slate. To do this, you can use a number of cutting and holing tools. 1. Find out the pitch of your roof
