How to fix roof

Preparation of the truss under the new cover is very labor intensive. But only if you will devote much attention at this time and will not be mistakes that could prove to be even tragic consequences. Must be removed, all fungus items or their parts - even those that were in the vicinity of the fungus. Removed is also decayed wood or substantially damaged by insects.

As a rule, the patch must be replaced only because of the deformation and decay. Individual old patches that are damaged can be reused. However, all the old patches, and so you need to break, because the distance between them will not fit into the new coverage. Old patches were deployed at 1-1.5 m, and now should be deployed in the 1930-1935 cm spacing, depending on what material will be used and what is the angle of inclination of surface of the roof.

Remember

Remember If the formwork was made, it must break the tar paper and remove the damaged parts, replacing them with new ones. Very often, the old design is only rafters and. Please check carefully as they are able. If there is any slot in them rot or infestation by insects or fungi, you need to replace a damaged section or the whole item. Always sharing the load-bearing truss is done in advance of their relief - support adjacent truss sections. But not always need to replace damaged rafters.

Often enough to be strengthened. This can be done bilaterally covering rafter boards usually 32 mm thick and turning bolts, or leaning, for example, additional reinforcement - combining elements of the rafter with a post. Yet another way is to reduce the load by adding additional rafters between the existing ones. Very often, it appears that the wooden structure deformed under the weight of the roof. In this case, the surface of the rafter offset by so-called offprints. All wooden elements that are used to repair the truss, should be pre-impregnated - the best pressure.
