1557. Roof Maintenance

At first, Qin Shiou thought it was someone coming, but there was no warning at sea, and no visitors on land. Later, when he saw tigers and leopards dressing up and calling at their overalls, he realized that the little guy was also going to change into a suit.

He explained a few words that it was for work, and the tiger and leopard bit one of his trouser legs, and he had to change into that set of body armor no matter what.

Qin Shiou was so pissed off, the body armor is heavy and not very breathable, I don't understand why the two little guys like to wear it so much, he is not a smug person, who did the two little guys learn to be so smug?

Helpless, he would not listen to what he said, so he had to take out the dog's body armor and put them on.

After putting on, the two little guys became happy, and then dawdled after Qin Shiou, as if showing off their clothes of similar color.

George and Vivienne were so teased that they took out their mobile phones to take a photo with the tiger and leopard. Lalawang also cooperated very well, and they were full of affection for the camera.

Qin Shiou waved his hands, indicating that everyone should start working.

George instructed the teenagers to mix detergent with warm water and wipe the tiles on the exterior wall from the door to both sides.

Under the wind and rain, the original milky white tiles have turned into a dull yellow or green because of being covered with moss. The moss can be wiped off, but the changing color cannot be wiped off.

The villa is full of the vicissitudes of the times. George said with emotion: "This house is at least half a century old. My father's cottage in the country has such a construction style. Time flies so fast."

The whole house is built of wood, and the wood in some places has rotted. Qin Shiou needs to replace it, or use a sawdust gun to fill it with wood chips. Finally, it needs to be sealed with glue and painted with a layer of paint. Very complicated.

For this kind of old house, it will cost a lot of money to repair it, and the key point is that it is a waste of time. For rich people, it is better to rebuild a set.

Qin Shiou is used to living here. I don't think it's necessary to change houses. Moreover, only the corners and corners of this villa need to be repaired. Overall, it is still very good. For example, the solid wood stairs in the house are very strong. After decades of use, there is no creaking sound when stepping on them. rock.

Canadian houses, especially country houses, are mainly made of wood, unlike the domestic use of concrete and bricks. The local timber is plentiful, and the cost of building a house using timber is also low.

For example, in Farewell Town, all the trees on the island belong to the government, but if anyone wants to build a house, they only need to apply, and they can buy a piece of wood on the ground at a very low price.

In this way, even if a new house is built,

Because it is still made of wood, it still needs maintenance, and the maintenance cost is not low. About 2% of the money is spent on maintenance every year.

The jobs that the teenagers have to do are the simplest and the least dangerous ones. Cleaning the floor, cleaning doors and windows, weeding, etc., mainly depended on Qin Shiou and the fishermen.

Shaq introduced to Qin Shiou: "The most important thing to maintain a house is the roof. Farewell Island is rainy and snowy. Moreover, there are often strong winds landing, so the damage to the roof is the greatest. We will go up later to see the aging of the roof. It has been in the past two years. Snowstorm, estimated to have caused damage."

After the ladder was built, several people tied safety belts on their bodies, and then went up to the roof of the villa.

In the first year, several warehouses in Daqin Fishing Farm collapsed due to wind and snow, but it was repaired by Shaq and Kraken, and the villa was fine. The materials used are more sophisticated, and professional anti-corrosion has been done. Stronger resistance to rain and snow.

When I went up to the roof, I saw that the roof of the villa was made of layers of wooden boards. Some have broken several layers, and some look complete, but they will be broken into pieces when you touch them, and they are already old and out of shape.

There should be no problems with the roof of this kind of villa, otherwise it will easily cause more damage to the house. For example, once the rain leaks, it will obviously corrode the walls, because the walls of the villa are also made of wood, so it is not as simple as mold, or even rot.

And if the roof insulation is not good, the air conditioner in the house will be turned on for nothing in winter, and the temperature will not be raised. Even if the air conditioner is turned on 24 hours a day, it will be useless.

In Canada, the roofs of wooden houses need to be repaired about every 5 years. This kind of repair is a major repair, and many things need to be replaced. Canada is sparsely populated. Except for the city center, most people live in small villas. It is basically a replacement. It costs four to five thousand Canadian dollars, and the average person's monthly salary is gone.

In addition, the roof has to be replaced every 25 years, which is more expensive, and there are no tens of thousands of Canadian dollars that cannot be taken down.

Qin Shiou discussed with Shaq and others: "Do you want to have a major repair and replace them all with modern glazed tiles?"

Shaq shook his head, and said: "Don't change it, the glazed tiles look good, but they are too heavy, and will cause a great burden on the walls of the house. Moreover, the wind and snow on the island are heavy, and with the pressure of the glazed tiles, the burden on the house will be even greater, so wooden boards are used. Just fine."

Mr. Qin is very particular about people. Hemlock was used for the roof at that time.

Iron Mountain is the most elegant and widely used tree species in the North American market. It is slightly lower than Ponderosa Pine in terms of strength and is more suitable for anti-corrosion treatment. After pressure anti-corrosion treatment, it is both beautiful and strong, comparable to the natural and durable North American red cedar .

Hemlock is great for roofing because it has great stability, a low coefficient of thermal expansion and contraction, and is resistant to sunburn. It is common sense that almost all wood will turn black after long-term sun exposure, but hemlock can still maintain the color when it is newly sawn after years of sun exposure, making the roof very beautiful.

These hemlocks have been treated and have a layer of transparent paint on the outside, which is a mixture of anti-corrosion paint and strengthening paint, which can not only enhance the anti-corrosion performance of the wood, but also increase its strength.

This is one of the advantages of hemlocks, they have excellent adhesive properties and can accept a variety of surface coatings.

The roof has several layers. After Qin Shiou repaired it with hemlock wood, he added another layer of charred wood.

Even if the roof of the country house is made of wood, hemlock is generally not used, but carbonized wood is used.

Carbonized wood is made by applying high temperature to homogeneous carbonization of wood. It does not need to use chemical agents. Its ability comes from itself, so it has more stable anti-corrosion and resistance to external forces.

Moreover, the surface of the carbonized wood has a dark brown color, as if it can absorb sunlight, which is very beautiful.

Carbonized wood has low moisture content, not easy to absorb water, stable material, no deformation, good heat insulation performance, simple construction, convenient painting, no special smell, and anti-rot, anti-moth, anti-deformation and cracking, it is simply the best wood for external use choose.

In addition, it has the advantage of light weight, because it has been carbonized, completely degreased without grease, less in weight, and less pressure on the walls and wooden beams of the house. (To be continued.)
