Rolled roofing technology installation

Low-slope roofs can be weatherproofed on a practical and economical basis by installing rolled roofing. With this technology, rolls of material—usually made of asphalt—are rolled out and attached to the roof deck. Because of its affordability and ease of use in comparison to other roofing techniques, it is frequently selected.

First, the roof surface must be prepared, making sure it is dry, clean, and clear of debris. This step is essential because it guarantees the rolled roofing will adhere properly and last a long time. To add more waterproofing and protection, a base layer like roofing felt or synthetic underlayment is frequently applied next.

The rolled roofing material is placed onto the roof after the surface has been prepared. After cutting it to fit the roof’s dimensions, it is attached with adhesive, nails, or staples, depending on the product and the manufacturer’s instructions. To create a continuous barrier against water and weather, great care is taken to overlap seams and edges.

In order to guarantee the effectiveness and longevity of the roof, it is crucial to conduct routine inspections and carry out any required maintenance after installation. For sheds, porches, and other similar structures where affordability and ease of installation are critical, rolled roofing is a popular option.

In this post, we’ll look at the simple and affordable way to install rolled roofing, which is a common option for roofs on homes and small businesses. We’ll walk you through each step of the procedure, from cleaning the roof’s surface to rolling the material and making sure it seals properly. Gaining an understanding of the fundamentals of rolled roofing installation can help you achieve a long-lasting and weather-resistant roof for your home or business, regardless of whether you’re a do-it-yourself enthusiast or a homeowner seeking an affordable roofing solution."

The correct device of the roll roof

A building without a roof is inconceivable. It is the barrier that stops heat leakage and shields the interior from atmospheric precipitation. The monolist of the roof will determine how comfortable the home is to live in for the most part. Clay and sheet iron were previously used to create the tightness of the roof. The roof required frequent repairs because these techniques were not very strong. The scenario has evolved with the growth of the building sector and the discovery of new materials. A novel approach to roll roofing installation has surfaced.

They typically use melted roll materials to produce a trustworthy roof waterproofing.

What is waterproofing for

Waterproofing is arguably the most crucial component of the roof’s apparatus. She is the one who keeps leaks in the roof covered. This preserves both the attic overlap and the characteristics of the materials used to make the rafters. Products with water-repellent qualities from the construction industry are always used to create the waterproofing layer. Manufacturers of roofing materials provide a wide range of options to ensure the home is comfortable to live in and durable.

The type of roof device itself determines which waterproofing roofing coatings are best. Private homes typically have a gable roof or a damaged roof. Here, roll roofing material and membranes with a polyethylene or polyhlorvinyl base are frequently used as a waterproofing layer. An additional circumstance in structures with flat roofs. Swimming materials are used in the great majority of cases to create a waterproofing layer on the roof.

Types of roller materials for roofing

Bitumen-based materials—of which there are two types—are laid using specialized mastics that are made of molten bitumen.

Materials on a polyethylene basis with a thin film protecting the lower adhesive layer.

Components that are melted onto the roof’s surface. Their technology allows them to operate a gas burner.

All roller materials can be classified as single- or multi-layer carpet intended uses. The former are typically made up of a lot more layers of bitumen, polymer components, and fiberglass. They have a pushing-shaped upper decorative layer composed of foil, shale, sand, and basalt. Hydropecloisol, glass insulus, Rubitex, fiberglass, prophetic skill, and glass insulator are the most sought-after roof devices.

Properties of rolled roof

When working with roll roofs, you can complete the coating installation quickly and with extra effort.

Despite the fact that these types of roofing are difficult to call elite, they are often indispensable in modern construction. The simplicity of their laying allows you to carry out work at a fairly fast pace. The undoubted advantage of these materials is that they can be laid on flat and hollow roofs up to 11 degrees of the slope, which is impossible when using ondulin and other coatings. The roll roof is elastic and, as a result, is not subject to cracking. It has high strength characteristics and acts as a sound insulator. These materials comply with all fire safety standards and are made of environmentally friendly components. They retain their high thermal insulation properties even with prolonged exposure to ultraviolet rays.

Working technology on the installation of roofing using roller materials

Roll material laying technology has unique properties. its primary producers of Isoflex and Technonikol. Most rolled coatings are in fact. They are not utilized on roofs that have rafters or ceilings made of wood. They are used as a coating for hollow and flat roofs. The most common material used for this purpose is melted roofing material (Euro-Ruberoid). This material is made of fiberglass that has bitumen applied to both sides. Modern roofing materials are strong and resilient, in contrast to their antiquated counterparts that had a cardboard layer. How should these repairs be made to the roof device?

Because roller roofs are elastic, there is less chance of damage to them.

1. Preparatory stage. First of all, the concrete or other surface must be cleaned of garbage and dirt. It is desirable that there is not even small sand left. In the event that the roof is repaired, then the old coating is removed.
2. Cracks and chips of the concrete surface should be eliminated using cement-sand mortar.
3. Priming the base with a bitumen primer.
4. Gluing roofing material occurs due to softening the lower layer of the canvas. This can be done using a gas burner or white-spirit.
5. Rolled material is rolled out so that its direction is perpendicular to the drainage of water. You should start styling with the lower parts of the roof or from its edge, if the roof has no slope.
6. Warming up the lower layer of the material, the roll is gradually rolled forward. Such a coating will last at least a quarter of a century.
7. Proper gluing of the paintings and strengthening angles is carried out by mastics based on bitumen.

Utilizing bitumen mastic to lay roofing material

1. The base on which the material will be laid should be cleaned of dirt.
2. Hot bitumen mastic is prepared. Then it is a distance of 0.7-1 m to be the surface of the roof.
3. The manufacturer processes the lower layer of the roll material with talcum to avoid sticking strata. Therefore, as the work progresses, it is thoroughly swept manually with a brush with hard bristles. This must be done, otherwise the clutch of the roof with the surface of the roof will not be strong enough.
4. The roll roofing material is gradually rolled into the distance that is treated with bitumen.
5. Those places that fell on mastic are thoroughly aligned, starting from the middle. It is necessary to ensure that there are no “bubbles”.
6. Когда полотно будет полностью раскатано, по его поверхности нужно пройтись специальным, довольно тяжелым валиком. This is done to improve the quality of adhesion of the material with the surface of the roof.
7. The next roll is laid so that a overlap of 10-15 cm is formed.

The multilayer device of the roof

It is well known that the roof must endure heavy loads from the elements, such as wind, rain, snow, and temperature variations. As a result, the coating’s strength ought to match their resistance. A multi-layer pie made of roofing material or other roll material is assembled for this purpose. The roof’s slope affects the thickness of the material. The number of layers can range from two to five depending on this factor.

When covering flat roofs, the maximum number of material layers are required. In this instance, it is capable of supporting a person’s weight and even surpassing it without causing harm to itself.

When the slope of the pie is no more than two to three degrees, it is called a four-layer pie.

If the roof slope is up to 10 degrees, three layers of ruberoid are required. You can safely use two layers of roofing material, underlying and external, if the slope is greater than this.

Roll roof technology is a straightforward and dependable method. Everyone is compelled to use this contemporary material to cover the roof.

Soft roof of rolled materials (without surfacing)

Most of the materials for the installation of soft roof are produced in rolls. They are intended for flat roofs or pitched, but with a small slope – up to 30 °. Mount roller roof materials on the pitched roofs with a slope of more than 15 ° rarely – under their weight they slide off the ramp. They have a low cost, they are mounted simply, modern materials allow them to operate without repair for 10-25 years. It is such a warranty period that manufacturers for materials give. But, how long the roll roof will be operated, depends largely on how well it is made. With poor work, even the best materials will not save. Therefore, many owners of cottages or private houses I prefer to do everything on their own, with my own hands. On the main points of the device of roll roofs with mechanical fastening (on nails and screws) or using mastic and talk further.

Construction of roller roof components

Rolls of roofing material have a standard width of one meter, a length that can vary greatly from seven to twenty meters, and characteristics that vary over even larger ranges. So, you must comprehend the species in order to select the material for the roller roof.

Classification by type of base

It is important to first define the soft roof’s foundation before selecting the roll material. They are as follows:

• Unconferential. These are materials made of processed rubber (isol) or bitumen (brisole). There is a new material based on Butil-kauchuk (hydrobiles). It turns out by rolling crushed raw materials through the rolls that form the sheet. Most of the materials have a thickness of 2 mm. They are used mainly in the lower layers of the roof pie to waterproof the base.

The primary purpose of unconnecting rolled materials is waterproofing.

Construction cardboard is the foundation of Ruberoid’s construction.

Numerous materials are available that are based on fiberglass and polyamide.

Polyester is the foundation for the best and most resilient materials used in roller roofs. They have a 15–25 year lifespan. Since they are pricey, they are typically applied as roofing coatings on the upper surfaces, while the lower lining layers are composed of less expensive materials, typically fiberglass or baseless materials (used as a waterproofing coating).

Types of a binder

A knitting protective composition covers the base of rolled roofing material on both sides. It might be:

• bitumen (waterproof based on asbestos paper, glass -ruble);
• tar, bitumen-defense compounds;
• Rubber composition (glassizol)
• rubber-polymer;
• polymeric.

The best qualities in compositions of rubber and polymer-bitumen. A portion of them can withstand temperatures as high as +150 °C, while others are made to work in extremely cold climates (as low as -40 °C).

On the one hand, foil is adhered to the bitumen-polymer binder using foilizol.

There is foilizol, a roller material for foil-based roofs, for areas with high temperatures. On the foil, bitumen-polymer or bitumin-resin binder is applied. The temperature on the roof will be 20 °C lower because of the reflective foil’s properties. Paints and varnishes with an atmospheric effect can be applied to the front surface. Foilizol is easily bent, cut, and fastened with roofing nails. Waterproofing (FG) and roofing (FC) are two examples.

Appointment

Seldom is a roll roof made of just one layer. Two to five layers are laid, depending on the structure’s complexity and slope. The lower ones are employed for better sound insulation, heat preservation, and waterproofing. They are referred to as "linings," and the letter "P" in the marking denotes them (the letter reflecting the material’s purpose comes in second).

Meaning of the letters in the marking

Given that it bears the majority of the mechanical load and is subject to climatic and natural factors, the upper layer ought to be more resilient. The most costly materials are used for this layer. They are denoted by the letter "K" and are referred to as "roofing."

Types of protective coating

Weatherproofing is necessary for binders used in the manufacturing of rolled roofing materials. A protective layer is applied by sprinkling with different levels of grinding:

• coarse -grained (K);
• fine -grained (m);
• dusty (P);
• scaly (h);
• special for alkalis or acids.

Coarse-grained scattering adds aesthetic appeal in addition to protection.

The letter on the label that indicates the kind of sprinkle costs the third. Dusty or fine-grained podp is strewn on both sides of rolled materials used for lining. Its job is to keep the roll from gluing.

Along with a coarse-grained or scaly crumb that protects the coating, there is also a fine-grained or dusty crumb applied to the back of the roofing roll material. Sprinkling is painted in various colors to provide an even more beautiful appearance. Typically, these colors are blue, green, brown, burgundy, red, and gray.

Method of installation

On the base, the majority of the components for the roll roof are melted. To do this, liquefied gas cylinders are connected to special burners. Their assistance causes the astringent’s lower layer to melt and clutch with the base or previously applied material. This technology is applied to flat roofs that have slabs of reinforced concrete covering them (garages, for example).

How roll roofs are installed on mastic

In private housing construction, flat roofs are very rare in our country. On small houses, this is usually a gable roof, less often – a single -sided. The rafter system and the crate of these roofs are wooden, the use of open fire on them – a large risk and owners of cottages or small houses are looking for a rolled roof that does not need to be melted. There are such materials. Some of them are attached with mastic, part is nailed with nails (about them a little lower). There are materials with a self -adhesive layer. All that is needed is to remove the protective film, roll out the material and press it tightly.

Roll roof composed of a layer of self-adhesive material

Roller roof

Most often, flat concrete roofs are used to lay saved roll materials. They may be placed on a metal foundation in specific circumstances (such as when fixing garage roofs). Here, the foundation is the roof material itself. Liquid waterproofing for initial treatment is all that is required. Two choices are available:

• Bitumen primer. Suitable for concrete and metal. There is a finished form – in buckets, you can do it yourself – mix bitumen with diesel fuel.
• Penetrating waterproofing based on cement. It contains polymers, the chains of which block the pores along which moisture seeps. Such processing significantly reduces the water absorption of concrete. Her minus is a high price. And the second-in order to melt the roofing material on top, you will have to miss the roof with bitumen mastic on top. It turns out expensive. But after such processing, even if the upper layers miss the water, the roof simply cannot flow. If at least a small slope is made towards the drain (a prerequisite, by the way), the water will go away, almost without leaking down.

A continuous base is constructed on the pitched roofs underneath the roll roof.

A continuous base is required on pitched roofs with a rafter system for roller roof materials. Most bowls are constructed from a single, continuous piece of OSB, plywood, rubberized, or dodgy board. However, these surfaces serve as fuel, and a burner is used to melt a rolled roof onto them. Next, use roll roofing materials that are glued to mastic or that are installed mechanically using slate nails.

There are a few more non-flammable material options from which to construct the roller roof base: flat slate, GVL, Central Special Forces, and Professor (galvanized). Special overlays and long, pointed screws with plastic sleeves are used to fasten items on these bases.

An illustration of the fasteners used on the Technonikol roll roof

Prefabricated bases are composed of two layers of sheet material that has a minimum thickness of 8 mm. The second layer is positioned so that the first layer’s seams overlap with the second layer’s sheets (displacing the seams).

Supplies needed for a rolled roof without a surface

They’re not that common, but they do exist. Fastening technique: roofing nails on a special mastic (usually on a mastic for flexible tiles), galvanized with a wide flat hat. Some have a polymer film covering a self-adhesive base. This film is removed during installation, and the laid portion is rolled with a heavy metal roller in an effort to prevent air bubbles.

Therefore, the materials that have been nailed to mastic have a self-adhesive base:

• Glassesol. Based on fiberglass or fiberglass covered with bitumen. Files on bitumen mastic. Warranty period – 5 years.
• Ruberoid. Based on construction cardboard impregnated with alloy bitumen. Mounted on bitumen mastic. Warranty – up to 5 years.
• Technoelast Solo. A bitumen-polymer binder is applied to the polymer basis, has an increased thickness (at least 5 mm), can be used without additional lining layers, has increased fire characteristics. It is laid on mastic with additional mounting on nails or screws, it is necessary to fuse seams. Serving life-25-30 years.

As you can see, an option exists. It’s true that there are just two categories—very expensive and very cheap materials—but you can make a decision based on your immediate plans. You can use inexpensive materials if you need to cover the roof temporarily for a few years. It makes sense to use expensive roll roofing materials if they are intended to last for a long time.

Roll roofing device without surfacing

Whatever the roof’s base material, it must be level, dry, and pure. No dust or debris. Just unadulterated substance.

It is possible to construct a roll roof on a pitched roof, but you will need to use specific materials and adhere to guidelines. The issue is that the roof’s roller materials have a fairly substantial mass. If they are not properly fixed, they collapse due to their own weight. Special precautions must be taken to ensure that this does not occur. The following guidelines apply to roll roof installations using mechanical mounts:

• With a slope of a slope of less than 15% of the canvas, rolled in parallel to the slope. Statement starts from below, move up.

When there is a slope, the roof is rolled out parallel to the slope up to 15% of the way.

Plan for installing the fasteners

Fixing canvases on horizontal joints: a guide

Sealing the pipe’s output

An extra layer is applied where pipes or antennas pass through the roofing pie. It is adhered to the base of the mastic directly. A unique rubber-shaped component is used to seal the opening created by a round pipe passing through a roll of non-melted roofing. This hat is elastic and has a rubber skirt on it. It affects pipes with diameters ranging from 110 mm to 250 mm.

A formed piece that allows a pipe to go through a roll roof

After being pulled onto the pipe, the rubber cap drops, allowing the skirt to freely rest on the base. The skirt’s bottom is heavily smeared with pressed mastic. Installing the fastener requires retraction from the skirt’s edge by 10 mm, with a maximum step of 200 mm. Sealant (which needs to be heat-resistant for chimneys) is poured into the intersection of the rubber cap and pipes.

Next, roofing material is sprayed from above and secured with washer-bearing screws or nails around the pipe. There should be at least 4 fasteners surrounding the pipe, with a maximum installation step of 250 mm.

A joint having vertical structures (brick pipe, wall adjacent)

An extra layer of underlying material is laid where the roof meets a vertical wall. It must descend at least 250 mm to a vertical surface, with at least 200 mm resting on the incline. An extra layer’s whole surface is covered in firmly packed mastic. The upper portion is then still fastened to the regional rail made of metal. Screws with washers that are at least 50 mm in diameter are used to fasten it to the vertical surface. A polyurethane sealant is poured into the joint between the rail and the wall.

An illustration of how adjacent to the vertical wall is organized

If the roof is insulated, multiple extra layers can be added to guarantee a high level of tightness (see the figure above). Every one of them extends 100 mm past the preceding one. Bitumen mastic is used to smear each, but the bar is only nailed to the upper portion; the intermediate can be secured with screws and washers spaced 200 mm apart.

These are all of the essential considerations when installing a roll roof without any surface.

It’s not always the case that soft roll roofs melt. Materials with self-adhesive, mastic, or nail fixation are available.

Construction of houses

Rolled materials cannot be called aesthetically attractive. Nevertheless, there are conditions in which the roll roof is almost the only option for coating the roof. This is a flat roof, a single -sloping or multi -sized roof with a small slope – up to 30 degrees. The device of the roll roof provides tightness and water resistance of such roofs. Garages, storage facilities, hangars, retail premises, enterprises and high -rise buildings are covered with roller materials. The installation technology of roll roofs depends on many factors, including the type of material and the slope of the roof. At least three people will need at least three people to perform work. How is the styling, what should you pay attention to and what rules to observe, we will tell in this article.

Types of materials for rollers

The days of using solely roofing materials as roller materials for roofs are long gone. Their useful life was limited to five to seven years because the bitumen cracked in the presence of sunlight and extreme temperatures, and the cardboard base was easily destroyed by water. Bitumen materials now have much better properties, a 15–25 year service life, and increased universality thanks to modern technologies.

Contemporary rolled materials feature a more robust base, a more intricate structure, enhanced plasticity, resistance to frost, and multiple attachment options for the base.

The basis of the basis, the material that connects the two, and the percentage of sprinkle all vary among rolled roofing materials.

Glassholst, fiberglass, and polyester are used as the building blocks for roll material. On a polyester basis, the most costly, dependable, and long-lasting material is taken into consideration.

In place of a binder Use both polymerized and oxidized bitumen. Polymeric materials are more durable to break attempts, more elastic, and resistant to temperature variations, making them suitable for use on roofs with intricate reliefs. While many materials are employed as polymer additives, the most effective is stylbutadianstyrol.

The size of the fractions that are sprinkled varies depending on the type of material and how it is rolled. Differentiate Bright-colored, medium-sized, fine-grained, flour-shaped, and sprinkled with scales. Since protecting bitumen from direct sunlight, strengthening it, and increasing its resistance to mechanical loads are the main purposes of sprinkling, most roll materials only have sprinkling on the front side of the material.

I would like to draw attention to materials that lack a foundation separately. We refer to them as "unconscious." These materials are made by heating polymer binders along with different fillers and additives, and then rolling the resultant composition into canvases.

There are four distinct generations of rolled materials in total:

• Ruberoid. As already written, the material is not durable, but they continue to be used to cover the roofs of uncertain objects.
• Substered roofing material. It differs from the usual roofing material in the fact that on its basis there is already a layer of bitumen, during the melting of which the canvas of the material is glued.
• Glass -rubled. Fiberglass or polyester is used as the basis. The glass -rubleroid is more durable than the usual roofing material, its service life reaches 12 to 15 years. Not afraid of temperature changes and frosts, as well as ultraviolet rays. It is considered a more reliable option for arranging a roll roof. Attached by salary or mechanical consolidation.
• Membrane rolled material – The most modern at the moment. The service life of membrane material reaches 20-25 years. It uses the most reliable and durable binders, fiberglass as a basis, as well as colored granules of sprinkling. The main difference between membrane roller materials is that they are self -adhesive. On the underside there is a special protective film that hides the adhesive layer. It is enough to remove the film, roll out the material, level it and it will stick it itself when the sun"s rays warm the adhesive layer of the base.

Consider the marking when selecting rolled material. These kinds of coatings exist:

Use of material bearing the proper marking is restricted under certain circumstances. For instance, lining roll material is limited to usage as the innermost layer. The top layer can be made of roofing material, and adding intricate vertical elements is easy with elastic.

Roller roof: fastening and arrangement technology

The technology used to install roll roofing is dependent on a number of variables, chief among them being the roof’s slope.

For instance, the appropriate number of layers for the roller material is:

• 2 layers are enough if the slope is more than 15 %;
• 3 layers if the slope of the roof is 5 – 15 %;
• 4 layers, if the roof is flat, slope 0 – 5 %.

The maximum roof slope that allows for the use of rolled materials is 25 percent.

The following is the technology used to install roll roofing on a flat roof:

• Base in the form of a concrete floor slab;
• Vapor barrier film to protect the insulation from wet vapors coming from the premises;
• Thermal insulation material. Most often used stone mineral wool in plates and extruded polystyrene foam;
• Screed with a layer of 2 – 7 cm;
• Rolling roofing material in 2 – 3 or 4 – 5 layers.

The layers of the pie appear as follows if the roof is composed of metal profile:

• Roofing material – corrugated board;
• Thermal insulation material;
• Rolled roofing material.

Basically, hangars and other warehouses are covered using this technique of roller roof laying. Please be aware that pairs from the heated room should not be allowed into the base. Furthermore, since less insulation is available, placing the roll material on top of the insulation is not the best course of action. However, this technique is still employed because it is typically not advised to apply too much screed to such roofs.

Implementing roll roofing technology on a pitched roof:

• Vapor barrier film inside the attic or attic;
• Thermal insulation material between the rafters;
• Waterproofing superdiffusion membrane;
• Continuous crate in the form of sheet sheets or moisture -resistant plywood;
• Rolled roofing material.

It is necessary to space out the layers of rolled material such that the locations of overflows and joints do not line up.

In addition to the cost of the material used to lay the roll roof, other factors that affect the cost are the style technology and the fastening technique. For instance, installing material in two layers on a ready-made base will cost 7.e. per square meter.If a screed and insulation need to be laid, this work will cost 40 at.e. per square meter. The cost per square meter for mechanically laying membrane material on a ready-made base is 14.e.

Hard roofing materials can be fastened in a few different ways:

• Mechanical method using roofing nails. Usually used to fix the first lining layer.

• Frusting the material. A gas burner is used, with which the lower bitumen layer of the material melts and the canvas is glued to the base.
• Gluing on bitumen mastic. The base is thoroughly coated with an adhesive composition – the bitumen mastic of cold application, and then rolled material is glued to it. Thus, all layers of the roof are attached, from the first lining to the roofing last.

• Self -adhesive materials. As already written, there are materials whose lower layer is adhesive. He melts and acquires adhesive properties from heating under the sun"s rays. Such materials are simply easy to fix with a roller in the places of overlap and joints.

Paying is the most typical method of attaching roller roof material. The final class of self-adhesive materials is less common since it includes more expensive materials. Yet, the use of membrane materials in flat-roofed residential and retail buildings is growing.

Laying roll roofing: schematic

The roof’s slope determines where the roll material paintings are placed.

Rolling materials are laid out starting at the lowest point on a flat roof.

On the roofs that are pitched and have a slope of less than 15% Laying is done with the skate in parallel. It is essential to begin at the overhang and work your way up from below. In order to allow the water to drain away, the canvas is cut off and placed on the roof ridge after the material has been laid on the roof’s slope.

On roofs that are pitched and have a slope greater than 15% The act of laying is done across the skate. The lower edge drops to a 15-cm overhang, and the upper edge must unquestionably pass through the horse. The same procedure is used to coat the second slope. The horse must be passed through by the upper edge.

The roof’s slope affects the overlap’s size as well. The overlap between the inner layer canvases should be 7 to 8 cm, and the outer layer canvases should be 10 to 15 cm, if the slope is greater than 5 °. Any overlap in layers should be at least 10 cm if the slope is less than 5 °.

Layers cannot be laid in a transverse direction. This is particularly valid for flat roofs. Only one direction should be used when layering rolled material, and overflows should be placed 10 centimeters apart.

The process of installing roll roofing using fusion technology

Flat roofs are most frequently laid in a fed manner. The styling technology is a specific flow of steps that have to be taken, none of which can be skipped.

Phases of roll roof installation:

1. The arrangement of the drain.
2. Creating a ramp.
3. Installation of a storm receiver.
4. Laying vapor barrier material.
5. Laying thermal insulation material.
6. Laying a reinforcing grid.
7. Laying a cement-sand screed.
8. Laying roofing around the funnels of water and aerators.
9. Installation of roofing on parapets and other vertical and complex elements.
10. Primer of the screed and all places of adjoining to vertical elements primer.
11. Frusting of roller material – 1 layer.
12. Setting the material in the places of adjoining.
13. Purvery of roller material – 2 layers.
14. Installation of a clamping bar.
15. Installation of the apron on vertical elements – galvanized.
16. Installation of a parapet from galvanizing.

First, all trash, dust, and dirt must be removed from the concrete base. It needs to be cleaned off if there is an old coating on the surface. A repair composition is used to cover up any chips, cracks, and potholes. The repair crew should start all additional work only after they are totally dry. You can install storm windows and gutters at this time.

Installing vapor barrier materials

Vapor barriers are made of film or membrane materials. They need to be laid with a 10 to 15 cm overlap. Building tape is used to glue together every joint. For all vertical elements, the vapor barrier is being developed to a point where, in the end, it is higher than the intended placement of the thermal insulation material.

Installing thermal-absorbing materials

Flat roof thermal insulation materials include extruded polystyrene foam and mineral wool slabs. Two layers of thermal insulation material are layered to prevent the formation of cold bridges at the plate joints. It should be noted where the joints are between the heater slabs.

Slabs of thermal insulation can be fastened to the base with glue or with specialized dowels.

Following the insulation layer, a layer of 2 to 7 cm of leveling screed is applied. In a screed that is 5 mm thick, temperature and shrinking seams must be done. The seams’ linear dimensions ought to be 6 by 6 meters.

Sides and a height of 10 cm should be constructed in the meters where the roofing material will touch the vertical elements. They can be carried out with cement mortar. Simply fill the arc that a vertical element and base form.

The screeds are laid, allowed to sit for four to six hours, and then their surface is covered with a primer made of half-diluted bitumen and kerosene. Alternatively, a ready-made primer is sold.

Roller roofing material can be laid once the primer and screed have dried.

Installing a roof that has melted

Waterproofing the temperature-shrinkable seams should be done first. This is accomplished by cutting off 15 cm wide stripes and applying bitumen mastic to the base. The roll roof canvases can then be laid:

• Laying starts from the lowest point. The roll is unwound and fits into the place of future installation. Before starting to fix it, it is necessary to check its integrity.
• First of all, the edge of the roll of the roll is fixed. To do this, the edge is heated by a gas burner and is crushed to the very edge of the site where it will be fixed.
• The canvas is again rolled into a roll to the place of fastening.
• Now you can heat the burner itself with a burner. The gas burner is kept so that it warms up the surface of the base where the canvas will be attached, as well as the lower surface of the sheet itself. As a result of heating in front of the canvas, a bitumen roller with a layer of 2 cm should form.
• The technology of work is as follows: one person warms up the fabric with a burner, the second hook turns the canvas during the gluing, and the third – rolls it with a roller. This can be seen in more detail in the photo.

Roller roof installation: picture – Example

• If the canvas is heated correctly, then a bitumen 2 cm thick should be at the edges.
• Walking on the newly laid roll material is undesirable.
• A roller person should carefully remove all air bubbles. After gluing, it is advisable to check the fastening of the edges of the material. The poorly fixed edges must be torn off with a spatula and warm the gas heating pad again and crush to the base.
• The edges of the roll must be rolled with special care. The movement of the rink along the roll material should be at a certain angle, starting from the middle of the canvas and moving to the edges.
• The canvases are glued with an overlap: longitudinal overlap – 10 cm, end – 15 cm.
• To lay rolled material on parapets, it is necessary to make the following: cut a piece of the required length, then attach its upper edge to the parapet with a mechanical way, then glue the canvas with the base to the base.

• To lay the material in the corners – internal and external – it is necessary to cut off a larger canvas and glue it with an overlap.
• To lay the material around the reception funnel of the drainage system, it is necessary to cut off pieces of the canvas and glue them so that squares 70×70 cm are formed around the funnels.
• The second and third layer of roller material is attached exactly in the same sequence. Do not forget about the locations of the adjoining vertical objects, parapets, funnels. After each layer, additional layers are laid in these places.

Keep in mind that only one direction is required for the laying of roll material.

The cold-rolling roll roofing technology

The cold method of roll roof installation differs slightly from the hot method. We highlight the most evident technological variations:

• Before laying the roll, it must be rolled out and left in this position for at least a day. If this is not possible, then it is necessary to roll out a roll, and then roll in the opposite direction.
• The laying of the first roll is carried out as follows: the roll is rolled to the middle, the size of the canvas is checked, whether it is enough to the start of the installation, then the expanded part of the canvas is again rolling into a roll. As a result, it should turn out like this: a roll divided into two rolls in half.
• Then one person smears the base with mastic where the roll material will be laid. It is enough to process an area of ​​no more than 1.5 m2 at a time.
• The second person rolls a roll on a base missed by mastic.
• The overlap of the roll material should be: longitudinal 8 – 10 cm, end – 15 cm.

Apart from applying roll roofs on mastic, there exists an alternative method of cold styling. Rolls made of membrane can be positioned mechanically or with glue.

The cost of laying membrane roller materials for glue is high, so mechanical styling is more frequently employed. Specialized welding equipment is used to weld the membrane roof panels.

Thermoplastic panels are securely fastened using heated air that reaches 600°C. A heated special roller-roller is used to roll the edges. The canvas is adhered to vertical elements with the aid of a building hairdryer.

Connecting the roll-off roof with vertical components

The locations where a roller roof adjoins vertical elements are thought to be the most complicated because there is a significant chance that the material will fall under water. In these locations, rolled material is laid in at least two layers:

• The first piece of such width is cut off that its upper edge enters the vertical element at least 25 cm.
• The upper edge is fixed with a mechanical way – with nails or self -tapping screws.
• The rest of the canvas is glued to the base.
• The second piece of such width is cut off that its upper edge enters the vertical element 35 cm.
• The upper edge of the piece is folded into a small steering wheel of 5 cm, applied to the vertical base and is fixed using the mounting bar.
• The rest of the canvas is heated and glued to the base.

Roller Roller Roll: Technology of Installation

One characteristic of the roll roof installation on the pitched roof is the use of a continuous OSP or plywood crate as the base. Additionally, it’s important to pay special attention to skates, vertical elements, yendovs, cornices, and overhangs.

As previously stated, the material must be laid parallel to the skate if the roof’s slope is less than 15%. The first canvas is located farthest inward from the edge; the cornice overhang should be released by at least 12 to 15 centimeters. A clamping board is then used to secure this hanging edge. The next step is to lay from the bottom up. The next few rows are laid with a 10-cm overlap. The final canvas is placed on a horse with at least a 25 cm overlap. Then, using precisely the same technology, they are placed on the second slope.

You can lay the material across the skate if the roof slope is greater than 15%. To accomplish this, roll the horse tightly from top to bottom, leaving at least 30 to 40 centimeters of overlap.

The attractive material can be attached to the pitched roof using mastic adhesive or by melting and gluing. A stick machine is used to join the painting edges in a mechanical method.

The material is laid in four or five layers to cover the ends and lands. The initial three layers are applied right away, spaced 10 cm apart. On a slope, the fourth and fifth layers are placed with layers of rolled material in between. The canvases are adhered to the apples with glue if their width is less than sixty centimeters. The canvases are divided into pieces and adhered together if the width exceeds 60 centimeters. In this situation, it is imperative to guarantee that the water flow proceeds unimpeded. The material starts to settle from the bottom for this reason.

A 10 to 15 centimeter margin is left when laying material in areas with overhangs and cornices. After that, roofing nails are used to secure the wrapped edge. Steel used for roofing is placed over the cornice edges on the building’s sides. It is necessary to install gutters where there are overhangs.

One of the simplest ways to cover a roof is to lay a roller roof. The most important thing is to watch the technology to make sure the edges are securely fastened and that no air bubbles remain underneath the material.

Constructing homes It is impossible to describe roll materials as aesthetically pleasing. However, there are instances where the roll roof is practically the only choice.

1. Prepare the Roof Surface:	Clean and smooth the roof deck to ensure proper adhesion.
2. Install Underlayment:	Lay down roofing felt or synthetic underlayment to provide a moisture barrier.

Because rolled roofing is inexpensive and simple to install, it’s a sensible option for a lot of homeowners. Rolling roofing is an excellent choice for do-it-yourselfers who want to cut labor costs because, in contrast to traditional shingles, it comes in large rolls that are easier to handle and apply.

It is essential to properly prepare the roof surface before installing rolled roofing. This entails clearing the roof of any debris and making sure it’s smooth and dry. In addition to adding extra waterproofing, applying a base layer of tar paper or roofing felt helps to establish a sturdy base for the rolled material.

The adaptability of rolled roofing to various weather conditions is one of its main benefits. Although installation is usually simpler in warmer weather when the material is more pliable, it can be installed in both warm and cold climates. For the roof to be durable over time and to stop water intrusion, the edges and overlaps must be sealed correctly during installation.

Rolling roofing requires very little maintenance. Its lifespan can be increased by routinely checking for indications of wear and tear, such as cracks or loose seams. The lifespan of the roof can be increased by promptly repairing any damaged areas with roofing cement or patches made specifically for rolled roofing. This will help to avoid more serious problems later on.

In summary, for a lot of roofing projects, rolled roofing is an affordable and useful option. When installed and maintained correctly, it can offer dependable weather protection for homes, which is why homeowners looking for affordability and longevity frequently choose it.
