No matter how reliable and durable the roof is, no matter what high-quality materials it is made of, over time it will still have to be repaired. Minor maintenance, correcting minor roof defects is quite simple and obvious, and there are many articles and other more visual educational material devoted to it all over the Internet. However, in some cases, such repairs do not solve the problem that has arisen, then more serious intervention is required. In such a situation, there is only one correct solution - a major overhaul of the roof.
Types of roof repairs
Depending on the situation, different levels may be needed. roof repairs. Depending on the complexity, they can be divided into the following categories:
- Maintenance;
- minor repairs;
- roof reconstruction;
- overhaul.
Each type of work has its own characteristics and requires a number of specific activities.
For example, current repairs that require regular performance are the least expensive, but at the same time the most inevitable. With its help, minor flaws, caused primarily by the time of operation, are eliminated.
Thus, the overall condition of the roof is improved, which avoids more serious interventions.
Small cottage roof repair has a more compelling reason to do so. This can be caused by corrosion or mechanical damage to the roof, causing leaks and other unpleasant consequences.
To eliminate them, you need to make a little more effort, but in most cases, all minor roof repairs come down to replacing individual elements of the coating or applying appropriate patches.
Reconstruction of the roofing is required in special cases, when the holes in the roof that have appeared are so large that the situation cannot be corrected by replacing its individual parts.
In this case, the entire roof covering is completely replaced with a new one, but the rest of the roofing system remains the same.
And finally, the most serious type of repair work at height is a complete overhaul of the roof.
This is the most complex and time-consuming process of all mentioned, it is designed to radically correct all the shortcomings of the existing roof and requires a significant investment of time and resources.
Conditions for the overhaul
One of the following reasons may lead to the need for a major overhaul:
- Significant deterioration of the roof over time.
- Serious damage to the roof due to corrosion, sudden mechanical impact, fire, or other tangible factor.
- Various defects caused by the initially incorrect design of the roof as a whole, or its individual parts.
A prerequisite for a major overhaul can be each of these reasons individually, as well as any combination of them.
Obviously, over time, the roof does not become newer. And if, throughout the entire period of operation, it is not properly dealt with, then in the end it will come to a state that only the most serious intervention can correct.
You can close up constantly appearing small holes as much as you like, but sooner or later the general condition of such a roof will make itself felt.
Therefore, at the first signs of a general dilapidation of the roof, repair of the roof as a whole is required.
However, time is not the only factor leading to serious roof damage. Such things can happen quite suddenly, as a result of unforeseen circumstances.
It can be a fire, a tree that has fallen on the roof, lightning strikes a metal roof, etc. There can be many situations that lead to one inevitable choice - a major roof repair.
And finally, another often encountered reason for the forced overhaul of the roof. It consists in design errors made at the stage of the initial creation of the roof.
This can include either an incorrectly laid roofing or insulation system, or their complete inconsistency, as well as many other various factors.
Such errors can lead to the most unpredictable consequences, so it is better to correct them immediately after detection and not lead to possible losses.
Overhaul method
The main stages of the overhaul include:
- dismantling of the old roofing;
- dismantling of the cement screed, or other existing supporting structure;
- removal of insulation, as well as the entire protective system;
- repair or replacement of the lower layer of vapor barrier material;
- restoration of all subsequent layers of the roof.
Thus, a complete replacement of all components of the roof structure from the lowest insulating layer to the outer roofing is carried out.
Removing the roofing sheet can be done in many different ways, depending on the type of fastening and roofing material. In the case of working with tiles, all fasteners should be gradually removed, gradually removing all elements of the coating.
More specific types of roofing - such as seam roofing or roofing using modern rolled materials - require the use of special devices and devices for dismantling.
If a partial repair of the roof was previously carried out, then all its consequences should also be removed.
It can be a variety of patches, additional inserts or putties.All this is neatly removed along with the total mass. roof coverings.
Advice. If it is not intended to reuse the elements of the old roof, then when disassembling it, you can not stand on ceremony. However, you should still be careful - the sharp corners of the fragments can seriously injure.
After that, the supporting structure under the outer covering is disassembled. Its role is most often played by a cement screed with wooden structures such as crates located on it.
All this is also carefully disassembled and removed from the place of work.
Then comes the turn roofing cake - an insulating layer that protects the interior from various external influences.
If during the period of operation the necessary maintenance of the roof was properly carried out, then many elements of this part of the structure can remain completely intact.
Such layers can be reused for further repair work, so you need to deal with them as carefully as possible.
The destructive part of the repair is completed by the removal of the vapor barrier, which is the bottom layer of the entire roof.
However, in the absence of any significant defects, this layer can be left alone, since it is extremely rarely damaged, and its presence is a design necessity.
Now the layering of new materials begins, replacing the damaged layers.
Here everything happens in exactly the same way as during the initial construction of the roof - in compliance with all building codes and according to the new plan, an insulation system is assembled, a supporting structure is mounted on top of it, to which the external roofing is attached.On this, the overhaul of the roof can be considered completed.
