Soft roof repair technology

Specialized methods are used to repair a soft roof in an effort to preserve its longevity. Soft roofs are common because of their flexibility and resistance to weather. They are usually made of materials like bitumen or synthetic rubber. But as time passes and they are exposed to the elements, they may begin to wear down, leak, or tear.

In order to preserve the lifespan of their roofs, building managers and homeowners must be aware of the latest advancements in soft roof repair technology. Soft roofs, in contrast to traditional roofs, call for particular techniques that take into account their particular construction and materials. In addition to extending the roof’s lifespan, efficient repairs also avert expensive damages that might arise from neglected problems.

Selecting the appropriate materials for sealing or patching, correctly preparing the surface, and determining the kind and degree of damage are all important components of soft roof repair technology. These procedures are essential to guaranteeing the long-lasting and successful repair, giving property owners peace of mind.

Through investigating the procedures and methods employed in soft roof repair, people can learn how experts handle typical problems like holes, seam separations, or UV-induced deterioration. With this information, homeowners can make well-informed decisions regarding upkeep and repairs, extending the lifespan and general health of their soft roofs.

Roof repair documentation

The following documents serve as guidelines when performing soft roof repairs:

  • estimate (work of work). It takes into account all planned repair measures on this roof. For example, the dismantling of the roof, preparation of the base, the installation of new material and sealing seams, the creation of a waterproofing layer. The estimate includes the cost of supplies and combustible materials, as well as the cost of their delivery. This document will help to evaluate the budget of future repairs and make a decision on its own conducting it or to provide the opportunity to do this to specialists;
  • SNiP (building codes and rules). During the repair, it is important to follow the requirements that are set forth in the SNiP “Repair of the Soft Roof” under the number 11–26–76. It indicates all the necessary materials for waterproofing, types of mastic, roofing materials and requirements for the procedure for performing work;
  • PPR (project production project). This document is important if repairs are carried out on the roof of an apartment building. It indicates the rationale for repair work, the results of the roof examination, its characteristic, methods of organization and methods of roofing production.

"At "All about the Roof," we explore the fundamental methods for fixing soft roofs and provide homeowners with useful advice on how to handle typical problems. This article walks you through the necessary steps to prolong the life of your roof, from sealing holes and tears to making sure it is waterproof. Knowing these repair techniques will guarantee that your roof lasts for many years and protects your house, regardless of shingle damage or weather-related wear and tear."

Types of damage and type of repair

A routine inspection of the soft roof is necessary. It will be beneficial to quickly detect any breaches in the roofing’s integrity and carry out the necessary restoration work. Common issues with the soft roof are taken into account:

  • bloating;
  • decay, the appearance of fungus and moss as a result of the formation of cracks with accumulated water;
  • stratification of the material at the joints of the paintings;
  • mechanical damage-appear due to the possible contact of the roof with antennas, branches;
  • dark spots;
  • bent edges of bitumen tile tiles.

There should be two preventive inspections per year, at the very least. In this situation, it is advised to routinely clear the roof of snow, debris, and branches. By taking these steps, you can prolong the lifespan and reduce repair costs.

Three different types of soft roof repairs are available, depending on the type of damage:

  1. Local or current – involves the elimination of small defects of the roofing canvas.
  2. Capital – is carried out in the case when local repairs did not give the result to ensure proper waterproof roof. Or if the damage area exceeds 40% of the roof area.
  3. Emergency – most often performed as a result of a serious leak or after an unforeseen violation of the integrity of the roof (when a small part of the coating is damaged).

Maintenance

When minor flaws in the soft roof are found, current repair is done. The nature of the problem determines how to solve it. For roll roofs, for instance, the following repair options are utilized:

  • bloating – pierce the place of bloating and make a cross -shaped incision. Bend the ends, clean the material from the inside, dry and smear the entire inner part with mastic. Next, apply the edges of the material on the base of the roof and iron well. If necessary, glue the patch on top and smear again with mastic;
  • Metting the junction of the joint – lift the material a little, dry the roof under it with a burner or a building hairdryer. Only after that, apply bitumen to the damaged area, lower the material, press it tightly or roll it with a roller. It is recommended to treat a problem place on top of the seam with mastic;
  • The roof with an uneven surface, water accumulates in some places – pour the entire surface of the roof with water and mark the places where the water lingered. After that, remove the water, sink the roof, smear the marked places with hot mastic or covered with an additional layer of roofing material as a thickness of more than one millimeter to level the surface. Then lay the top layer of the roof and cover it with a special composition that prevents the negative impact of the external environment.

It is also necessary to replace the bitumen tile in the damaged area. In order to accomplish this, the trowel needs to carefully lift each damaged plate and pull out any defective ones that are nearby. Using a nail, remove the nails. Install fresh roofing material, fasten it with nails, and use silicone sealant to further seal the joints.

Overhaul

The following order is followed when replacing the soft roof:

  1. Remove the old coating. Clean the surface of garbage, dust and residues of building materials.
  2. If necessary, remove the heat and waterproofing layer.
  3. Make a cement-sand screed. If there are problems with a ramp, then perform it, using expanded clay or other material. If the roof was insulated, then a new insulation should be laid on the damaged area and waterproof.
  4. Lay new roofing material. Soft roll roof is laid hot or cold. In the first case, the lower layer of the material is heated by a gas burner, and then pressed to the base of the roof. When installing a cold method, special glue or telescopic fasteners are used. In the case of using bituminous tiles, the material is mounted on a self -adhesive base and fixed with nails. The laying of the material occurs with an overlap of 10-15 cm.

Emergency repair

The roof’s equity repair requires that the coating’s violated portion be restored as soon as possible. Putting in a sizable patch where materials have been damaged is one example.

This measure can stop leaks from forming, but it only works if the damaged area doesn’t take up more than 20% of the entire roof.

In order to apply patches, you must:

  1. Remove all visible defects by cutting or stripping with a sharp construction knife.
  2. Clean this part of the surface of the roof of dirt, dust, garbage.
  3. Damaged area pour in bitumen mastic. If desired, you can use sealant.
  4. A piece of roofing material, the size of which is larger than the area of ​​the damaged area on the treated area.
  5. Cover the roofing material on top with another layer of bitumen: distribute it with a roller over the entire surface of the patch, paying special attention to its edges.

On bitumen tiles, a patch can be applied. The repair process is the same; the only difference is that silicone sealant or a special solution are used for gluing.

This repair technique works only if there is an obvious flaw causing the leak.

Necessary materials

The soft roof is repaired with various materials. The decision is based on which roof pie layer needs to be fixed:

  • for the upper layer – "uniflex", "linloker", "isoplast". Their service life is more than 10 years;
  • For the lower layer – "Beriplast", "Tiploine", "Technolast". They are characterized by increased elasticity and ability to create additional thermal insulation.

Mineral sprinkling should be incorporated into the materials of the roof’s upper layer in order to protect against solar radiation. Such a canvas’s thickness should be selected between 4.5 and 5 mm. Additionally, the roll roofing material can be thinner for the bottom layer.

Mastic for laying in a cold way

Typically, a mastic that can be used to lay roofing material without warming is employed. The roof pie’s interior layers are fixed with it. It is essential to select only that kind of mastic, which consists of bitumen and a dusty mixture like lime or gypsum.

Make your own mastic if you’d like.

You will need to combine two parts bitumen and gasoline with one part filler. However, after the bitumen is heated to 180 degrees Celsius and the water has evaporated completely, the components must be connected. The resulting mixture needs to be cooled before repair.

Here’s how to use a mastic like that:

  1. The surface of the roof is thoroughly cleaned of dirt and dust.
  2. Dry and warm up the entire area.
  3. Apply mastic to the repaired area with a roller or brush. After complete drying, you can apply the second layer.

Liquid rubber

Liquid rubber is occasionally used to fix soft roofs. It has the ability to form a seamless coating that essentially stops water from seeping into the roofing pie. Large repairs and minor crack sealing are done with liquid rubber.

Its unique quality is that the information can be used in two ways:

  • With the help of spraying from a spray gun – this method is relevant in the repair of roofs of a large area;
  • roller or brush – requires a longer time, so it is suitable only for local repairs or small buildings.

It is preferable to use the second approach for independent roof repair if there is no prior experience with specialized equipment.

Multiple layers are covered with liquid rubber. Furthermore, each new layer can only be applied once the preceding layer has fully dried. Usually, a 7–10 minute interval is used for this.

The actual application technology looks like this:

  1. Remove all extraneous objects, garbage and dust from the surface. Delete fat and oil spots. Rinse and dry the roof.
  2. Apply a cold solution of liquid rubber with a layer of 3-4 mm. If major repairs are carried out, then not immediately process the entire surface, but sequentially small areas.

Waterproof

Typically, roll waterproof is utilized when renovating a soft roof. This necessitates taking the old coating completely apart.

The structure of this melted material is as follows:

  • base (fiberglass or fiberglass);
  • modified bitumen coating on both sides of the base;
  • Slantsy Podspent as a protective layer.

There are two layers of waterproofing applied. The installation technique of cold and hot is applied. The following is the installation technology according to the method:

  1. Roll up a roll along the surface of the roof, cut off the desired length, then turn it off the edges.
  2. Having warmed up the lower surface, the roll is gradually rolled out and carefully press to the base. Gas burner is used for heating.
  3. Each subsequent roll should be laid in the same way, but with an overwhelming 10-15 cm.

Keep in mind that overheating can cause the material to break down or catch fire. Additionally, cold mastic is used to produce the waterproof material.

Careful planning and meticulous attention to detail are necessary when repairing a soft roof. A careful inspection is always the first step, regardless of the extent of the damage, even if it’s just small rips or larger tears. This entails determining the impacted regions and estimating the degree of the harm. You can use the proper techniques once you have a clear understanding of what needs to be fixed.

Patches and sealants are a typical technique for soft roof repairs. Patches are used to repair small tears or punctures in roofs. Usually, they are made of compatible roofing materials. On the other hand, sealants are used on joints and seams to keep them waterproof. These two remedies aid in maintaining the integrity of the roof and halting additional damage.

Making sure that the adhesion and sealing are correct is another important part of soft roof repair. This entails thoroughly cleaning the repair area to get rid of any contaminants or debris that might prevent adhesion. For long-lasting repairs that withstand weather and environmental stresses, adhesives and sealants must be applied correctly and in accordance with manufacturer instructions.

Finally, to make sure there are no new problems, it’s crucial to examine the entire roof after the repair is finished. In the long run, homeowners can save time and money by prolonging the lifespan of a soft roof with regular maintenance and timely repairs. These maintenance and repair methods will help you keep your roofing system strong and dependable while handling soft roof problems.
