How to repairing slate roofs ,roofing slate ?

Broken, broken, and missing slates should be repaired by experienced Slater, to prevent water damage to interior decoration, the roof and accelerated deterioration of the roof sheathing and degraded to the development of a structural member.

Damaged slate is the first by reducing or eliminating the nails pulled out of the Ripper. IF steel cut nails, rather than copper nails, laying on the roof to use the adjacent stone may be inadvertently damaged or displaced in the crawl process, which will also be repaired. If you do not slip as the stone itself, in the end that the hammer can be divided into slate slate slate dragged kicking. A new slate, stone, or salvage, should be consistent with the size, shape, texture and color of weathered old stone, and then slide into place and post the list of candidates, through the process of vertical integration between the top of a nail inserted about 1 inches below the slate two courses above the tail. [

In order to prevent the adoption of the newly created nail hole, a copper film for measuring the friction of about 3 "(7.5 cm) wide, 8" (20 cm) long, is based on vertical integration between the two fall slate, located just above the water permeability and above the new slate nails. To ensure that alternative methods, including replacement of stone metal hook, clip use, and with the tail curved in stone. Application of frankincense or damaged roof slate sealant should not be considered a viable maintenance program, because these materials, but in an effective, will eventually harden and crack, allowing water to enter.
Mastick also makes future repairs more difficult to implement, is ugly, and, when applied to the metal pan of water, to accelerate the corrosion.

When two or more broken slates lie adjacent to each other on the same course, or replacement of leaking water in the valley pan, preferably form a pyramid (that is, to remove a higher course, from the slate the diminishing number) in order to maintain the necessary number of bibs to a minimum. When re-installing slate, only the top of the pyramid in each slate will need a bibs. Along the pyramid will get two nails, one above the other two sides stone, exposed along its upper edge.

While many stone must be removed should be checked on the repair of the sheath rot and pronounced nails. General deterioration of sheathing plywood is not as difficult to drive nails through it a good substitute for wood materials (back production, reducing the adjacent stone). In contrast, a similar width and thickness, which should be used instead of the new board. As today's lumber production is slightly thinner than in the past in the name of the thickness, it may need to fill the new board, so that they lie adjacent to the existing sheathing board with the top flush. Pressure treated wood is not recommended, since it reduces the trend. This may lead to stone strikes have become displaced.

To allow proper re-laying of slate, the new roof sheathing must be smooth and solid construction. At least two nails should be placed through the new parliament, and between the boards in each raft should happen in the rafters of the ends of joints. Nail failure will lead to board the flexibility to make the difficult and cause nail stone slate adjacent relaxation process. Unevenness in the jacket will be displayed in the completion of the roof surface, and may cause premature rupture of stone. Roof sheathing in valleys and along hips, ridges, eaves and roof waterproofing membrane may cushion, and not coverage feel the extra protection against leakage. [

In urgent situations, such as when severe hurricanes or tornadoes blow numerous slate from the roof, the roof covering should be installed immediately the temporary storm to prevent further damage to the building's internal water, and to allow the drying process begins. Large-size plastic and vinyl tarpaulins are often used for this purpose, but is difficult to guarantee their place and can be blown in the wind. Membrane, carefully to the roof, the rest of the stitching, is a more viable solution, will allow sufficient time to record the existing roof conditions, plan maintenance, materials and order.

Slate roof is a local problem, and have longer to repair damage to the roof of the remaining viable life. If 20% or slate roof or roof slope is broken, broken, missing, or sliding out of position, it is usually cheaper, but not implementation, to replace the individual repair the roof. This is particularly the elderly close to the end of the roof repair their lives, because even the most experienced Slater is likely to damage more of the stone, while trying to repair. Depending on the age of slate, its expected service life and cause (s worse), it may or may not be cost-effective to salvage slates. Any deterioration of nails or pan of water is the failure of the roof, at least some of the rescue service should be able to use stone. When the rescue slate, and everyone must be sounded discovered the extent of cracks and faults, it has weathered. It is usually wise to salvage some of the time only the slate roof was replaced. In this way, the salvaged stone can be used for future repairs to the roof of the rest.
