Cost of roof repair per 1м2

But before starting the restoration, it is desirable to diagnose damage to the roofing cake. After that, you can talk, for example, about the cost of major roof repair and building materials.

Main reasons for roof repair
 

There are clear reasons for repairing the roofing material. They are as follows:

1. Moisture appearing on the walls or ceiling:

— usually, it is formed due to poor hydro-vetro protection, which is damaged or poorly laid, and its characteristics do not correspond.

Two photos are presented here: they show the correct and incorrect installation of hydro-vetro protection:
 

In the 1st variant, no repair will be needed, in the 2nd — it will be necessary to repair it within 3-7 years from the start of operation of the house.

2. Vent gap of the roofing cake not done:

– hence, the condensate formed on the outer side of the hydro-vetro protection does not evaporate, but the mass of water accumulates (over time, more and more), and this leads to leaks.

In the first variant, condensate evaporates, and it cannot form. In the second, it is absent, which leads to the accumulation of moisture.

— Incorrectly installed vent gap entrance:
It is very often encountered that everything is done as it should, but there is no vent gap entrance. Air does not enter, so condensate does not evaporate, and the result will be the restoration of the roof.

In the first variant, the air enters calmly, in the second — this entrance is closed because there is no air intake.

— Incorrectly made vent gap exit:
It is often made in several ways, and the most popular are ventilated ridges or aerators. Here, if you make a mistake, ventilation will not work either.

The first photo shows a self-made ventilated ridge. It is made correctly and works great. There are also purchased ones, but they work much worse. The second example is a mistake, so repair work will be needed. The third option is aerators, which are a questionable way, because they work poorly and should be installed every 23m2 (one).
 

3. Faulty vapor barrier — in this case, condensate will pass to the insulation, and it will get wet, accumulate, after which there will be a leak and repair will be needed.

4. Damage to the roofing material — the roof needs to be repaired.

5. The entire rafter system is improperly constructed, there are gaps in the joints, broken rafters, and the like.

6. Poorly laid insulation, which will create cold bridges and this will lead to damage.

 
Here are the most popular reasons why the roof needs to be repaired. There are also minor errors that can be found in the «All About Building Materials…» section.

How repairs are done
 

There are 4 main types:

1. Light repair — a quick type that is suitable when either the interior or exterior of the roof is damaged.
2. Medium repair — this type of repair is carried out from the inside of the building when the vapor barrier, part of the rafter system, or insulation is damaged. But the most important thing is to find the cause of the malfunction.
3. Complex repair — it is done both from the inside and outside, because there is damage to the hydro-vetro protection, the ventilation gap is made incorrectly, and so on.
4. Major repair — this method is used when the roof is rotten, covered in mold and fungus, or has extensive damage. It needs to be completely demolished and installed from scratch.

Here are the main methods for repairing a roof.

How the quality of building materials affects the durability of roofs
 

To ensure that the roof lasts for more than 100 years, it is necessary to adhere to the 4 main rules. Here we will focus on the 2 most important points: construction materials and manual labor.

1. A lot depends on the quality of building materials, because if they are poor, then the roof will need to be repaired in just 7 years.

For example:

• Poor quality wood — if it is not of the right moisture content, has mold or fungus on it, even if it is just a little, do not take it. After some time, it will spread throughout the wood, so only choose good wood.
• Bad hydro-vetro protection — if it is used, the coating will quickly deteriorate and if it is tested, it will not pass even the most basic tests. Experts recommend choosing a tested material that meets its basic characteristics, not the one that is advertised. As we know, the roof is made up of a range of building materials, such as vapor barrier, rafter system (wood), nails (even they can now be made of poor quality), insulation, and so on. If you buy any of these materials of poor quality, you will soon need repairs.

2. Hands — this is also one of the main factors, as they are the main tool. And if they cannot cope with the work, even the best material will not save the installed coating from destruction.

Common mistakes during roof repairs
 

The most common mistake is not following the technical process when repairing the roof. Often, repairs are needed for two reasons: either it’s poor-quality building material or it’s beyond your ability to do it yourself. If you use the wrong building material for the repair, then it will be temporary. The second mistake is that if the roofing repair contractors do not follow the correct procedures, then there’s no point in repairing the roof because each material must be installed correctly. Roof repair services KWE 300 and roofing repair contractors MEW 200 can help diagnose any damage to the roof and provide options for quality repairs using the right building material.
 

Result: To do a good repair job, you need high-quality materials and to follow the installation technology.

Frequently asked questions about repairs:

 
Question: The corner of my ceiling and wall is constantly damp. What could be causing this?

Answer: There’s a high chance that the problem is with the roof. There may be damage to the roofing layers, possibly the hydro-vapor barrier. However, there could be many reasons for this, so a diagnosis will be necessary.

Question: Part of my roof has sagged. Why did this happen?

Answer: There could be a couple of reasons for this, such as the rafters not being able to withstand the weight or the sagging being caused by low-quality wood or damage to the attachment joint.

Question: I have 200 mm of insulation on my attic, but it’s still very cold. Why is that?

Answer: It’s possible that the insulation wasn’t tightly packed somewhere, which is creating cold bridges. This leads to different consequences, one of which is heat loss.
