The roofing is a special craft, difficult and complete, especially with the use of slates and the work of zinc is the required complement. Apart from essential, strict and obligatory safety rules, you need to know some basic notions about materials as well as their use, cutting, fixing, levels. Start with a very simple site to familiarize yourself with these materials and the special environment of their installation.

Gutters and downpipes
1. When building a roof, whether new or renovated, and whatever the material chosen, tile or slate, we must start by worrying about gutters and their descents. Whether they are to be created or replaced, they constitute the first work to be done, even before attacking the cover itself. The installation and alignment of the hooks must allow to create a slope of 3 to 5 mm per meter. Their fixing, in renovation, is to be adapted according to the positioning of the rafters. They are here fixed flat.
2. The hooks once laid receive the gutter. On this renovation site, a last batten is placed on the bank, just on the top of the hooks of the gutter. It will be the support of the hooks of the first row of slates whose lower edge will have to fall in line with the gutter.
Lay the slates
1. The slate installation begins with the installation of the hooks on the battens. The upper beak that clings to the wood of the batten, has a profile studied (clearly visible in the photo) to prevent its lifting and it is the lower beak that will support the bottom of the slate in the middle. Start obligatorily by the base of the roof from where the need to put the gutters before the slates.
2. Engage the base of the slate in the apparent beak of the hook which will be in the middle and tighten it against its neighbor, leaving only the thickness of the side hook.
3. Tap gently (the slate is a hard material but on its siding) the top edge of the slate using the roofer's hammer table so that its base hangs in the beak of the hook that supports it. There must be no play in order not to give a hold to the wind.
Cut the slates
1. To cut a slate, it is necessary to hang on the batten, the roofer's anvil by its lower tooth, then to put the slate on it, the line of rupture in alignment with the edge of the anvil. On this line, tap the facing of the slate with short snaps lined up, with the tip of the roofer's hammer to create that break line.
2. Hang your hammer on a batt, and press the slate on each side of the anvil. The slate breaks without damage. you have to equalize the two songs with the inner edge of the hammer
3. It is with the same part of this very specialized tool, and relying on its indispensable complement that is the roofer's anvil, that you can cut down an angle or make a delicate cut.
Nail the slates
1. On the side bank, take the extra precaution of nailing the slates so that they can not offer the slightest hold to the wind. An adjustable speed drill makes it easy to make the pilot holes according to the diameter of the wide headed nails provided for this purpose.
2. Proceed in the same way with the slates of the top of the roof whose top will be covered by a zinc ridge to ensure a perfect seal. The installation of special nails, broad head and curved and often equipped with a seal (twisted belly tips to better resist tearing), must be done without risking breaking the slate.
