Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a method for roof re-roofing work.

(b) Prior Art In old tiled roofs, the tartars 2 are arranged randomly at intervals of about 1 shaku 5 sun to 1 shaku 7 sun. A roof board 3 is placed on top of this taraki 2,
As shown in Figure 4, it is stretched with gaps,
The roof was covered with cedar bark, wooden feathers, etc., and covered with tiles. When re-roofing work like this, first remove the tiles, peel off the cedar bark and wood feathers,
Also, the tartar 2 and the roofing board 3 were removed, leaving only the main building 1, and then a new rafter was placed on top of the main building 1 so as to be orthogonal to the main building 1, and the roofing board was laid and roofed.

(c) Problems to be solved by the invention Since there are important items such as household goods indoors, it is prohibited to expose them to rain, but as mentioned above, when re-roofing work is carried out, the entire existing roof must first be removed. Because only the main building remained, if it rained heavily during the re-roofing process, it was impossible to prevent the household belongings inside from getting wet.

Therefore, a temporary roof is installed and re-roofing work is carried out, but installing a temporary roof increases the cost.

Furthermore, if the existing roof boards are removed and new roof boards are placed over the existing rafters, there is a drawback that the new roof boards are wasted because the gaps between the existing roof boards are uneven.

Furthermore, roofs that have been used for a long time often become uneven.

The present invention is a construction method that solves these problems and replaces a roof while dealing with rain showers and adjusting for unevenness without incurring any expense.

(d) Measures to solve the problem: Peel off tiles, cedar bark, and wood feathers, lay boards on top of the existing roofing boards, and cover them with waterproof paper. This board is
For example, a board like plywood. Furthermore, a new rafter was installed, and while adjusting the unevenness by inserting pieces of wood under the newly installed rafter, the new rafter and pieces of wood were nailed to the main building, and roofing boards were laid on top of the new rafter and roofing material was installed. Roofing.

(E) Embodiment An embodiment of the present invention will be described based on FIGS. 1 to 3. First, remove some tiles and cedar bark/wooden feathers from the existing roof. Then, the existing field board 3'
A plywood board 4, for example, is laid down as a board on the existing roofing board 3', and waterproof paper 5 is further pasted (see Fig. 2). Since there are important items such as household goods indoors, it is necessary to avoid getting them wet from the rain, but in this way, plywood board 4 is installed on top of the existing roof board 3'.
If you cover it with waterproof paper 5, you will almost never have to worry about rain leaking.

Next, new tarps 6 are placed at intervals on the plywood board 4 covered with this waterproof paper 5. At that time, if the roof surface is uneven, insert a piece of wood 9 under the newly installed rafter 6, and while adjusting the unevenness depending on the height of the piece of wood, nail the newly installed rafter 6 and the piece of wood 9 to the main building 1 with nails 7. (See Figure 3).

A new field board 8 is laid on the newly installed tarp 6 whose unevenness has been adjusted (see Figure 1), and then roofing material is applied.

In this way, the roof is reroofed one part at a time, and the process is repeated to reroof the entire roof.

(f) Effects As described above, in the present invention, boards are laid on top of the existing roofing boards and waterproof paper is applied, so even if it rains during the reroofing work, the reroofing work can be continued without worrying about rain leaking. Therefore, construction can be done at a lower cost than when using a temporary roof.

In addition, even if there is an unevenness in the existing rafters or roofing boards, you can adjust the unevenness and create a well-balanced roof by simply inserting pieces of wood in the necessary places.
In addition, a space is created between the existing roof board and the new roof board, allowing air to circulate from the eaves to the ridge.
It has the effect of heat insulation, soundproofing, and prevention of dew condensation.

Furthermore, the existing roof is not completely removed except for the main building, but the existing rafters and roofing boards remain as they are, so they can be used as scaffolding during construction, allowing for safe construction.

Claims (1)

[Claims] 1. In the method of replacing a roof that has cedar bark, wood feathers, and tiles on top of existing roof boards that are stretched in a manner that leaves a gap over the existing tarpaulin, the tiles, cedar bark, and wood feathers are removed. , Lay boards on top of the existing roofing boards, cover with waterproof paper, and place the new rafters on top of them. At that time, insert pieces of wood under the newly installed rafters to adjust the unevenness, and then install the new rafters and pieces of wood. A roofing replacement method in which the roof is nailed to the main building, new roof boards are laid on top of the new tarps, and roofing materials are applied.
