Dismantling of an old roof Construction
The main purpose of roofing structures is protection against negative atmospheric factors. Over time, the roof is wearing and begins to leak. On the other hand, the cause of moisture gets often lies in non-compliance with the construction standards. Dismantling the roof is needed if you decide to make a new roof. First, high-quality disassembly to maintain building materials, secondly, compliance with simple instructions will help you quickly perform work.
Preparatory stage
Disassemble the roof is inconvenient enough, since all the work is performed at the height. Therefore, the cost of dismantling the roof is high enough. But, if you immediately prepare all the necessary inventory, work without problems is performed independently. To dismantle the old roof it will take:
- high staircase
- roofing staircase
- screwdriver with a set of nozzles "Hexagon" and "Cross",
- motok rope,
- hammer,
- nail-breeder.
If the usual staircase is in the farm in almost everyone, then roofing, as a rule, you need to do. It differs from the usual hook presence that fixes the staircase at the skate of the house.
In addition, it is necessary to develop a system of blocks, with which the roofing material will be descended. It consists of:
- supports
- block mechanism
- rope,
- stands for cargo.
As a support use a thick board. It must be fixed in such a way that one end comes beyond the roof for one meter. Blocks are attached to the end and middle of the top edge of the board. Next, the rope is passed through them. Support for cargo consists of a flat wooden board with dimensions of at least 50x50 cm. In order for the free part of the rope accidentally slipped, it is necessary to make constipation on the reference board. For this, the cross on the cross is driven into the board two nails, and the free end of the rope is associated with several nodes so that it does not slip through the nails.
Dismantling roofing layers
Now go to the first stage of dismantling work. To begin, determine the type of roofing materials. It can be:
- ceramic tile
- wave slate,
- metal tile,
- bitumen basics
- "Live" roof.
If you look at the price list to dismantle the roof, it will become obvious that the disassembly of more modern materials is expensive. This is due to the fact that the process of installing such structures is much more technological, therefore certain difficulties arise.
Dismantling the old roof and the price of this service will be the smallest if the roof is covered with ceramic tiles. Such a roof is fixed using the "lock" technology, so it does not need to use a special tool for its disassembly. All the work consists in alternately withdrawing row of tiles. Start you need from below-up from the edge of the house.
Wave slate is fixed with nails. Therefore, it will take a nail to dismantle. At the beginning, you should remove the horse. Then, on top-down, dismantle the old slate.
The roof of metal tile is most difficult in disassembly. At first glance, it also disassembled, as well as slate. But there is one important difference. Metal tile sheets are much more and harder slate. Therefore, it will take at least two people to fulfill this work.
Dismantling the roof and the price of services for disassembling roofs on bitumen or living bases are fully justified. Perform this work independently impossible. Therefore, it is better to invite experts. The difficulty is that special expensive equipment is necessary. Often its price is not different from the cost of work.
Disassembling bearing structures
Any rattle of dismantling includes a procedure for disassembling bearing structures. It is important to perform the work consistently, otherwise the roof core collapses and cause injury. According to the technological card to dismantle the roof, the following steps can be distinguished:
- Disassembly of insulation materials.
- Disassembly.
- Disassembly of the crate.
- Disassembly of rafal structures.
Do not forget about Mauerlat. You should start disassembling the roof from this.
Ruberoid was used as sealants in old roofs. In order to remove it, it is necessary to arm a spatula. If a slightly hide the edge of the rubberoid, then the whole sheet is broken without problems. The work should be performed at the beginning of the spring, since in the summer the material is heated and it will stick to the wooden strip surface.
More modern roofs are isolated using bitumen bases or special waterproofing films. In the first version, it will be cheaper to disassemble and throw out the extender along with bitumen insulation. In the second - the sheets of the film are easily removed and suitable for reuse.
The extending represents the upper part of the roof to which the roofing material is attached. This is the only functional purpose of this element. Delete the extender should be directly from the attic. The principal value does not have the procedure for disassembly, but it is important to remember that the work should be performed sequentially, or from top-down, or bottom-up.
After completing this action, the roof is a framework. Now it is important to disassemble it correctly, whatever he fell apart. The procedure begins with the removal of retaining beams. Since the roof is no longer, they are not needed. Now only the framework remained. Its disassembly is carried out from above-down. At the beginning, bearing boards are removed, then supporting.
When performing each of the roof dismantling points is very important to remember that it is necessary to eliminate garbage and disassembled building materials in time. This will free the place to work and allow to protect the inventory from a random fall.
Dismantling of the roof and rates for this service oscillate too much. If you decide to use the services of professionals, it will be quite expensive. In addition, most builders are taken for any work, regardless of skills and experience. On the other hand, the independent dismantling of roofing structures will require time and significant labor costs. But, in the end, work will be made as it should be.
