Diy repair of a soft roof - materials and technology
Rolled roofing materials based on modified bitumen - a practical solution for a country house, urban cottage, garage or other outbuildings. They are characterized by high waterproofing properties, weather resistance, reasonable price and long service life. The main advantage of this option is the ease of installation, thanks to which roofing can be done by hand. In addition, roll materials are easy to maintain. In this article we will describe how the current and overhaul of the soft roof, which is necessary for the working condition of the roof, is performed.
Damage types
Roofing materials based on modified bitumen are considered the most resistant to the environment coatings. However, intensive operation and the lack of timely service do not remain without a trace. Soft roof repairs are performed if the following damage is done to the French:
- Cracks. As a result of repeated temperature fluctuations and exposure to cold, the surface of the soft roof is covered with cracks through which water seeps into the roof frame.
- Mechanical damage. Rolled roofing materials based on bitumen are easily damaged when struck with branches or stones fall on the roof surface.
- Breakdowns of the finishing layer. Intense wind load leads to the disruption of the upper layer of the roof, which will lead to leakage and further destruction.
- Wear. Each roofing has its own life and comes into disrepair due to constant exposure to water, temperature and wind.
- Rotting Under the influence of atmospheric moisture, the rolled materials become a “victim” of mold microorganisms or fungi, which leads to the rotting of the coating.
Important! If even minor defects that do not cause leaks are detected on the roof surface, it is necessary to urgently repair the soft roof to avoid further structural damage.
Types of recovery
The impact of environmental factors has a negative impact on soft roofing materials, gradually leading to complete wear or destruction of the coating. Repair of a soft roof is an inevitable stage of roof operation, which sooner or later every homeowner will have to go through. There are 3 types of restoration work:
- Spot. Point recovery is the restoration of the roof, damage to the surface which takes no more than 10-15%.
- Current. The current restoration is the process of reconstruction of the coating, which is damaged by no more than 40%. It is associated with a partial replacement of the top layer of the roofing roll roll roofing pie.
- Capital. If damages occupy more than 40% of the roof surface, then a major overhaul of the soft roof is performed. Such a reconstruction is carried out with the complete dismantling of the old covering and the laying of the new.
Consider that the dot restoration is the easiest, cheapest way to restore the roll covering with your own hands. To constantly monitor the condition of the roof, it must be regularly inspected. Only a seasonal inspection and repair of minor defects will help to keep the coating in excellent condition.
Point Recovery Technology
Spot restoration is performed when damage occupies no more than 15% of the roof surface. In this case, you can seal the defects with the help of peculiar patches that will prevent leakage and further destruction of the roof. To repair your own soft roof, you must:
- First, it is necessary to inspect the roof surface and trace the detected defects with white chalk.
- On the ground damage is necessary to make a cross-cut to squeeze out moisture from under the topcoat.
- Then you need to sand the damaged surface and degrease with alcohol or gasoline.
- Bitumen mastic should be applied to the treated surface and allowed to grab.
- Then you need to stick on the roof surface a patch of rolled material, the size of which is 20-30 cm larger than the defect.
Experienced craftsmen argue that roll materials are amenable to recovery. Small cracks on the surface of the roof are filled up even with liquid roofing material.
Capital reconstruction technology
The overhaul of roofing from roll materials is a technically complex process that can be performed only with special equipment and roofing experience. It is produced if the proportion of damage exceeds 40%. The technology of soft roof repair consists of the following steps:
- First, complete dismantling of the old roofing is performed. Need to remove all the materials to the concrete base.
- The base of the roof must be cleaned of debris, dirt and grease, and then thoroughly dried with a building dryer.
- Apply bitumen mastic to the base of the roof with a roller, spray gun or brush.
- After the mastic has dried, a new coating is laid. First, 1-2 layers of the lining material are mounted, and then the flooring of the finishing layer is performed.
Installation of a soft roof is performed using a gas torch, with which it is heated the bottom layer of material, and then glued to the base. Roofing with bituminous materials is performed in dry, calm weather at a temperature of +5 degrees.
Experienced craftsmen and manufacturers of roofing materials, note that timely maintenance of the roof is the key to a "healthy" state and long service life of the structure. Therefore, do not neglect the seasonal inspection of the surface of the skates and the timely detection of defects.
