The roof for a wooden house is installed immediately after its construction, since atmospheric precipitation can negatively affect wood, which is destroyed under the influence of moisture. Previously, the “final” roof in log houses was mounted only after their shrinkage, however, the development of modern construction technologies made it possible to significantly accelerate the process of building the house. So, for example, if lumber was used for construction, which has already undergone processing in drying chambers, then the shrinkage of the house will be very insignificant, so the roof is built immediately after the completion of all other works.
However, already dried logs are rarely used to build a house, most often it is a forest that has passed drying in natural conditions and containing still coherent moisture, which evaporates only after tens of years. Therefore, when erecting the roof, tolerance for shrinkage is made in any case. It is also not recommended for wooden houses as a rafters to use thinly profile metal, which when shrinking walls can be deformed and fall under the weight of the roof.
With a standard four -walled structure, as a rule, there are no problems and the roofing structure can be installed immediately on supporting undergraduate ties. In this case, the shrinkage of the roof will occur simultaneously with the walls, and the shrinkage process under such a weight will be significantly accelerated. However, such a design is most often used in the construction of baths and saunas, and at least one, the fifth wall that is suitable for the horse’s hobby is in the houses. The height of such a wall is much larger than the rest, therefore its shrinkage will occur faster, which can adversely affect the building as a whole.
To avoid negative consequences for the construction of the fifth middle wall use a different technology. The rafters are shed in the upper crown of the log house, but they do not attach to it, and the roofing is already laid on top. And only after one year, when the rafters will move a little along the wall gutter, they can already be fixed. This is carried out using galvanized nails and clamps. In each case, depending on the massiveness of the design and the quality of the applied raw materials, a certain technology is selected for shrinkage, which will be as effective as possible in this case, therefore, experienced specialists should engage in the construction of the roof in wooden houses.
