Arrangement and repair of a flat roof is done by two types of materials: soft or bulk. They provide excellent sealing of roofing layers, protect the house from the damaging effects of the environment and a long service life. There are typical roof damages made from soft materials that periodically occur regardless of the quality of the materials used.
Types of damage
To find out if there is a need for reconstruction of the roof, it is possible with a thorough examination of its surface. You can detect defects in the roof of the house if you just walk along it. Damaged areas may crack, swoop and swell.
Types of damage to a flat roof:
- stratification of the "pie": full or partial;
- swelling of the coating;
- the occurrence of bubbles;
- the appearance of cracks;
- the formation of depressions and funnels filled with rainwater;
- peeling of the coating around the chimneys;
- germination inside the coating layers of all kinds of vegetation.
If you periodically conduct a routine inspection of the roof of the house for defects, then a small current surface repair can be done by yourself. But if you do not do this on time, the defects will gradually progress, and the roof can begin to leak. In this case, it may be necessary not only to overhaul the roof of the house, but also to restore the interior decoration of the room.
The consequences of untimely roof repairs:
- proliferation of moss and other vegetation;
- the appearance of mold;
- deformation of wooden walls and floors of the house;
- violation of the interior;
- occurrence of leaks;
- icing of the walls of the house and floors in the winter;
- the appearance of multiple cracks,
- peeling of finishing materials, their accelerated destruction due to decay.
It is recommended to carry out preventive measures in each of the seasons:
- in early autumn so that there are no problems with a leaking roof;
- in spring, after snowmelt - to eliminate damage after winter;
- in summer it is necessary to remove leaves and clear the roof of moss;
- in winter you need to clear the snow on time.
This will help reduce the cost of ongoing home repairs.
How to repair a flat roof
Two types of repair can be noted depending on the size and nature of surface defects.:
- shallow current;
- capital.
There are two effective methods to repair a flat roof.:
- sticking on mastic;
- deposition using high temperature exposure.
Membrane Roofing
PVC membranes are a soft material for roof repair, with which you can repair easily and quickly.. A big plus of such coatings is that laying is possible with one layer directly on the old roofing material coating. The only requirement is that the surface should be clean (no stones, debris, old greasy stains, puddles of water).
To carry out the work you will need:
- PVC membrane rolls;
- apparatus for welding;
- scissors;
- roller;
- dowel nails.
Work technology
Rolls are rolled on the surface of the roof and cut the necessary pieces of paintings. The canvases are overlapped by 12 cm. The edges of the canvases are fixed with dowels and nails every 40 cm. The edges are connected with heated air from the welding machine. In this case, a stream of hot air is directed under the sheet and immediately rolled with a roller. This method is justified when repairing large areas.
The use of euroroofing material
This repair technology is much more economical, but the surface should be perfectly cleaned.. Flooring material is made in two layers. The first is the main one, and the second is the decorating one. Thanks to a special powder, the decorative roofing material is not afraid of the sun, frost, does not crack and does not dry out, is chemically resistant and has a long service life (about 30 years). The material is available in rolls.
Materials and tools for work:
- Two types of euroroofing material;
- Gas-burner;
- Special scissors;
- Hook.
Deposition technology
Strips of the desired length are measured and twisted again for convenience in rolls. Each sheet is heated with a gas burner and rolled, holding so as not to get burned, with an iron hook. In this case, the material is firmly attached to the surface. On top of the bottom layer, decorative is placed according to the same algorithm. Then the two layers are melted at the same time, providing reliable adhesion and durability of the coating.
Other methods
A small repair of the soft roof of the house can be done using an ordinary roofing material. Of course, it does not have all the advantages of modern analogues, but with small defects in the roof you can use pieces of roofing material, laying them on molten bitumen. The material can even be laid on top of iron or slate surfaces.
With small cracks in the slate plane, flaps of fabric in oil paint will help - they can repair minor damage.
Large damage fragments must be replaced or completely covered with new material.
How to correctly calculate the cost of reconstruction
The technology for minor repairs does not require such preparations; it can be carried out spontaneously without any preliminary preparation.
When planning a roof overhaul, it is quite reasonable to make a preliminary calculation of the cost of repairing a roof from rolled materials.
Procedure for repair planning:
1. Measurement of the territory within which it is planned to replace the coating.
2. Compilation of a list of all required materials, taking into account the nature of the defects.
3. Adding to the list of materials for the manufacture of cement-sand mortars, if you plan to update such sections of the roof.
4. To the result add 10-20% overspending of materials.
5. Consider the offers of various building materials stores, take into account promotions and terms of delivery of materials.
Overhaul
Overhaul of the roof requires large expenses and large time costs, however, the procedure itself can well be done with your own hands, provided that you have some skills.
Event Technology:
- Disassemble the roofing cake and check the condition of all insulating layers.
- If damaged coatings are identified, replacements should be made over the entire area.
- Make a cement-sand screed, following the instructions on the packaging of the mixture.
- Pour the solution with a layer of 2-4 cm and wait for the surface to dry.
- Make the primer a bitumen emulsion.
- Treat the entire roof area with mastic.
- Lay preheated parts of the whole web on the roof surface, pressing with a club. The procedure is easier to do together.
- Lay all strips with an overlap, keeping 15-20 cm of lining.
- Seal seams, joints and hard to reach places.
- If desired, an additional layer of soft roof can be made by rolling the roll in the perpendicular direction.
In order for the overhaul of the roof to give a result and save the next ten years from carrying out such events, all rules should be observed when laying the coating. It should also be noted that the condition of the coating will depend on the quality of the material selected. It is better to choose the products of reputed manufacturers.
