Ruberoid weight 1m2 during disassembly

The practical aspects of handling and removing this roofing material are critical to understanding the weight of Ruberoid per square meter during disassembly. Ruberoid, commonly referred to as roofing felt or bitumen membrane, is made to protect and waterproof roofs. Over time, the weight of Ruberoid per square meter becomes a practical concern, particularly during roof renovations or repairs.

When installed, a ruberoid usually weighs X kg per square meter. However, depending on the precise kind and thickness of Ruberoid utilized, this weight may change. Its weight may increase during disassembly due to elements like debris accumulation and moisture absorption, which will make removal more difficult.

Because Ruberoid is heavy and can tear or damage during removal, handling must be done carefully. Utilizing instruments such as pry bars and utility knives, roofing specialists can carefully lift and remove Ruberoid sheets, reducing the possibility of mishaps or injuries.

"Knowing the weight of a ruberoid per square meter is essential for safe and effective removal when removing it from roofs. This article examines the effects of ruberoid weight per square meter on handling and disposal issues during disassembly. By making these elements clear, professionals and homeowners can better plan for roof maintenance, assuring a safe and efficient procedure. Additionally, useful advice on handling ruberoid sheets during removal will be given in order to help preserve roof integrity and reduce the risks involved in handling heavier materials."

Why do you need to change roofing material

These days, it’s common to witness the process of taking off the previous roofing material from flat roofs. There are various reasons for doing this.

    Physical aging of the material. Ruberoid is the cheapest and most poor -quality rolled roofing material, which is made of bitumen and cardboard. Bituma reacts very negatively to ultraviolet rays, intermolecular bonds are significantly weakened under their influence, plasticity is lost, microcracks appear that turn into large cracks since time through which water can already fall. Cardboard is easily torn, not stretched, afraid of moisture exposure. Such roofs quickly begin to give leaks and require repair.

The roofing ruboroid becomes thinner with time, rips, and bald patches appear.

The weight at the roof’s base is increased by many layers.

It is required to remove previous roofing coatings in order to perform roof overhauls.

Vital. Changing roofing material requires extremely strenuous physical labor; there are currently no high-performing, efficient machines or specialized equipment available. The majority of the time, dismantling is done by hand; this type of work is low-paying and labor-intensive.

General technical characteristics of roofing material

Acquiring knowledge of technical parameters is imperative for accurately calculating the weight of a square meter of coating. Ruberoid is bitumen-soaked roofing cardboard with a layer of stone sprinkled on one side.

The composition and roofing material brand

Sprinklers are a necessary component of roofing systems and serve multiple significant purposes simultaneously.

  1. Protects the upper layer of bitumen impregnation from the destructive effects of UV rays. The fact is that even the most modern innovative additives in bitumen cannot significantly increase its stability, and stone particles completely protect the surface from harmful radiation.
  2. Improves the appearance of coatings. Stone baby has different sizes and color shades, which makes it possible to slightly improve the design characteristics of flat roofs.
  3. Warns the slope of the rolls. For these purposes, stone chips or special plastic film can be used.

Different kinds of salty shale sprinkles for roofing materials

The current state regulatory documents outline the requirements for standardized coatings, which the domestic industry should produce. The kind of roofing material determines all of its technical specifications, including a square meter’s weight.

Materials that are produced with quality should possess the following qualities:

  • roll width 1000-1050 mm;
  • The mass of the roll is 22–25 kg;
  • useful area of ​​10–20 m2;
  • A square meter mass ≈1.7 kg.

The manufacturer lists the primary attributes of the coating on the roll’s packaging.

This is only an estimate; every kind of coating has unique properties of its own.

Types of roofing materials and their intended uses are shown in Table.

Weight calculation methods

Two methods can be used to approximate the mass of the disassembled coating.

Theoretical method

The most challenging and infrequently achievable way to weigh a square meter of roofing material. Several starting data points are required for computations.

  1. Type of roofing material. The packaging shows the mass of the roll and the weight of a square meter of cardboard.
  2. The number of layers of the coating and their types. The larger the layers, the greater the mass of the square meter of roof coating.
  3. The amount of bitumen or modern mastics used during the production of roofing work. These materials reliably glue among themselves layers of roofing material. The thickness of the mastic is indicated by the manufacturer on the packaging, the mass of bitumen is regulated by building codes and rules.

Features of different roofing material brands

These data will roughly calculate the mass of a square meter of roofing material when disassembling. Calculations are made in several stages. The first determines the number of layers of roofing material. If the structure was not repaired, then there should be two layers – lining and roofing. You should immediately see if the bitumen primer was applied. If this material was used for primer, then the total number of layers of bitumen is two, one of them for fixing the lining layer to the base, and the second finish. Such requirements existed 30–40 years ago. Modern technologies for laying soft roofs mean one layer, finish rolls of roofing material are glued without additional application of bitumen.

Simple circumstances, however, are extremely uncommon; roofing materials are typically taken apart and reassembled from old roofs. Skilled builders advise estimating the number of layers by examining the portion of the roof pie.

You can quickly ascertain the number of layers on the roof by cutting a portion of the coating.

The mass of each coating layer must be multiplied by its number at the second stage. Immediately off the bat, it should be noted that the calculations will be highly approximate. Furthermore, maintenance could only be done locally, in the areas that flowed. Nobody can predict the number of these areas on the roof, their sizes, or how they will impact the precision of weighing a square meter of coating.

Practical method

A quicker, easier, and more precise method. A system like this determines weight.

Step 1: Select three distinct locations at equal distances from each other on the roof. The sites can be any size, although squares with a side of ten centimeters are advised.

Step 2: Grind the whole thickness of roofing material around the edge with a grinder. Remember that roofing material can have up to ten layers in certain situations. Saw until dust from concrete appears.

A grinder has removed bits of coating from the roof in a few different locations.

Step 3: Use an electric perforator or regular chisel to remove the roof. The most important thing is to not lose even tiny pieces, so even if it is torn, it is not a problem.

Step 4: Calculate the average indicator by weighing the available samples and converting the resultant value into square meters.

To weigh the removed coating pieces, they must be assembled.

The area of the roof must now be determined, and the weight of one square meter of coating must be multiplied by it.

Why do you need to know the weight of a square meter of roofing material

Every construction task is carried out in accordance with a project plan or budget. The volume and cost of each operation are shown in these documents; regulatory provisions are taken into consideration during calculation. As a result, wages are considered when disassembling and exporting the outdated bitumen coating.

How to dismantle the old roofing material with asphalt cutting

As was already mentioned, this is physically demanding labor. We start by thinking about the partial mechanized option. You will need a puncher and asphaltores for the task at hand.

Gentle roof cutters

Step 1: Measure the flat roof’s length and divide it into sections that are each one meter wide.

Step 2: Determine the roof pie’s total thickness. In order to accomplish this, you must drill a hole in the roof until the rushing back appears, then use the roulette to determine its depth. To control the asphaltore cutting process, this data is required.

To determine the thickness, the roof area is segmented and made in the clip coating.

Step 3: Set the cutting disk’s desired depth of descent, turn on the machine, and let it operate gradually. Avoid applying a heavy load; in normal mode, the engine should run smoothly.

Sensible guidance. Sometimes the cutting depth is not adjusted correctly. Move the device one to two meters. The appearance of dust and a change in the sound of the cutting can indicate whether or not the disk is slightly in contact with the concrete slab. If required, adjust the disk’s position.

Making a slice of the same depth is practically impossible because a flat roof’s surface has quite large ledges and hollows from repeated repairs. In order to make additional work easier, the cutting disk should be positioned so that it is in constant contact with the floor slab.

Step 4: Sprinkling the roof should be done in a 1.5–2.0 cm wide strip; accuracy is not very important. The entire length of the roof should have strobes.

Cut the stroke with the coating’s asphaltores’ assistance.

Step 5: After that, collaboration is advised. A single perforator inserts a sliced coating strip, tearing away all the layers from the base simultaneously, while another perforator pulls it slightly over itself. The truth is that as people age, the lower layer in some places becomes very easily separated from the concrete base; to remove it, simply pull with your hands instead of undermining the perforator. This makes the work much easier and faster.

Step 6: Create these grooves across the whole roof, with a one-meter space between each one. Such a width makes working with it easier.

A perforator is used to create grooves in the coating.

Next, use a perforator to remove the coating in turn, and have the helper wind it into rolls. It won’t work out right away; you need to have some degree of real-world experience. You will, however, be able to gauge how much work is being done after an hour and a half.


Removing the roofing material manually

The old roller coating can be manually removed if there is no asphalt cutter available and there is no desire to damage the grinder. Prepare old axes, crowbars, special scrapers, and other tools for this task. Before removing the roofing material, there are suggestions available for heating it. Yes, the material is easier after softening. However, the final decision must be made only after determining the cost of the heating itself.

Using a crowbar, the old coating that had been previously cut into squares with a grinder is pushed out.

One can only hope that the soft roof was disassembled with extreme care and flagrant disregard for technology, which would have left the lining layer’s adhesion coefficient with the base at its lowest. Ruberoids are easily broken off with only slight physical effort; shock loads are not necessary; the scraper can only glide across the surface. Maybe this is the only instance in which a marriage helps builders in their work.

Sensible guidance. Sweeping every area that has been removed right away will help to closely monitor the caliber of work. Furthermore, trash won’t wind up all over the building’s roof.

Material Type Weight per 1m² (approx.)
Ruberoid (tar paper) 2.5 to 4 kilograms

Comprehending the Ruberoid weight per square meter when disassembling is essential for all roofing project participants. The weight of this material varies based on its type and thickness; it is frequently used in roofing due to its waterproofing and durability qualities.

Ruberoid can be surprisingly heavy to remove, especially if it has been aged or saturated with water. This weight affects the logistics of handling and disposal, so it’s critical to budget for the right tools and labor.

Understanding the approximate weight per square meter is helpful in estimating the overall removal efforts and costs involved when planning for replacement or computing disposal costs. This information guarantees more seamless project management and keeps things unexpected during the renovation process.
