Roofing coverings do not last forever (no matter how much one would like this), and, sooner or later, the owner of a building or structure has to face a situation when the roof begins to lose its protective properties. Under the influence of precipitation, temperature changes, sunlight, possible mechanical damage, the roofing material is subjected to destruction - cracks, bubbles, peelings, breaks, and so on appear. And then leaks appear and the question: how to do high-quality and inexpensive repairs of soft roofs in Moscow, for example?

Costing includes a complete list of materials necessary for repairs and related work, wages of workers, possible overhead and unforeseen expenses, services of third-party organizations, if necessary, including delivery of materials, loading and unloading operations, removal of roofing debris and removing it from construction site. That is, the implementation of the entire scope of work, guaranteeing the precise fulfillment of the task set by the Customer: to repair soft roofs in Moscow.

Material price

Modern manufacturers offer a huge number of different roofing materials, differing not just in price, but also, of course, in quality. But, the price of the material is the main component in the total cost repair work. And the most expensive, by the way. After all, the labor costs of construction workers also depend on the structure and quality of the material used: it is customary to calculate construction costs based on the cost building materials.

Wage

Often wage is a contractual value and it often happens that upon completion of work, prices begin to creep up. But in the event that Customer there is an approved Performer Costing for roof repairs or, then they clearly indicate everything related to the payment of workers. As mentioned above, labor costs for builders are calculated based on the cost of the building material. Quite often this amounts to 50 to 100 percent of the total cost of materials.

We calculate the amount of work to repair soft roofs in Moscow

The scope of work determines the total cost of roofing repair work. Naturally, the larger it is, the higher the total cost. The scope of work depends on:

• total area of ​​roofing to be repaired;
• lengths of eaves overhangs, junctions with walls and parapets, thickness and height of the latter;
• the presence of shafts on the roof, their number and size;
• the presence of pipes and other elements on the roof, their sizes and quantities.

Estimate for roof repairs: how to make your own

An estimate for roof repairs is needed when planning repairs to the roofs of apartment, industrial and other buildings, the maintenance of which involves accounting. A correctly drawn up estimate for major repairs allows you to calculate the cost in advance necessary materials and calculate the budget for the upcoming event. In addition, when proper planning You can determine in advance the time that will be required from the start of repairs to the commissioning of the roof, adjusted for various factors that influence the completion time.

What does the repair estimate depend on?

Estimation is determined by the following criteria:

• Roofing type. Different roofing materials cost differently, and therefore the cost of repairs soft roof will differ significantly from the cost of restoring slate or tile coverings. Again, depending on the type of coverage, the price will vary installation work;
• Degree of damage to the roof covering. Severe wear of the roofing will result in its complete replacement, while minor wear will require local, and therefore less expensive, repairs;
• Roof dimensions. The larger the roof, the more roofing felt or slate, time and effort will be required for roofing work;
• Features of materials delivery. Being able to purchase the materials needed for repairs close to home will make shipping easier and save time and money. The presence of access roads to the house will make unloading more convenient;
• Season. It is easier to repair a roof with your own hands in the warm season than in the cold season. Experts share the same opinion, and therefore the price of work in summer and winter will be different.

Illustrations	Types of repairs according to the type of roofing
	Repairing a soft roof. There is a difference between major and seasonal repairs. In the first case, the old material is dismantled, the floor is restored and a new roll roof is laid. Along with laying the material on the floor, the roof and various superstructures, parapets, etc. are reattached. Seasonal restoration involves installing patches of weld-on materials over damage to the old coating.
	Repair slate roof . Such work is required either after the life of the material has expired, or as a result of local damage and leakage. Major repairs include dismantling the slate and inspecting rafter system for damage and laying a new covering. Local elimination of leaks is carried out by replacing one damaged sheet or by sealing cracks.
	Restoration of seam roofing. Metal coating given that correct installation durable, and therefore restoration may only be required after the service life has expired, that is, no earlier than 15-25 years after installation. As preventative measure, seam roofing made from corrugated sheets can be painted to prevent corrosion.
	Metal roof repair. Structures covered with metal tiles are durable and reliable, and therefore repairs may only be required after their service life has expired, when the entire coating is replaced with new roofing material.

What does the estimate form take into account?

The estimate form, which is drawn up when organizing repair work on residential, industrial, administrative and other buildings, contains the following items:

• List of upcoming works. The volume and order of upcoming work is determined in accordance with the previously drawn up defect list;
• Quantity of materials and units of measurement. The name and quantity of materials determined in accordance with the defective list is indicated;
• Estimated price of materials. The average price of materials and related products is indicated. When specifying exact numbers, you must refer to the sales organization;
• Estimated price of work. The form indicates the average price of the work, or exact numbers with reference to the organization providing the services;
• Correction factor. Simply put, it indicates how much the cost of repairs may increase and the reason for this increase;
• Estimated price in rubles indicating the time of calculation. That is, the total amount of money relevant at the time of the calculations is indicated.

What is a defective statement and what does it take into account?

A defect report or defect report is a document that indicates a list of all damages that will have to be eliminated during the upcoming work. The determination of damages that will be included in the defective act is carried out by experts.

For greater accuracy of the expert assessment results, it is advisable to coordinate the data from the defective list with experts from other specialized organizations.

The benefits of drawing up estimates when repairing roofs on private property

So, we have decided that when organizations repair construction projects, an official document with calculations is necessary for a number of reasons. How necessary are such calculations when doing DIY repairs?

Illustrations	Reasons for drawing up an estimate for DIY repairs
	Objective assessment of the complexity of the upcoming work. When starting work, you will have an accurate idea of ​​its complexity and will be able to decide whether to do everything yourself or use the services of professionals.
	No overexpenditure or shortage of materials. By correctly drawing up an estimate, you can decide with high accuracy what materials and in what quantities to buy so that there is no surplus left after the renovation is completed.
	Competent action planning. By planning your actions, you can complete the work on time without delaying the onset of bad weather.

Let's sum it up

Now you know why you need an estimate for major and routine roof repairs. If you have any questions about identifying roofing defects and making calculations, write about it in the comments to the article.

Estimate documentation is a mandatory part of any construction project. An estimate is a document that provides the results of calculating construction costs, broken down by cost item. These include:

• construction workers' wages;
• taxes;
• contributions to the budget from the wage fund;
• the cost of basic and auxiliary building materials;
• business expenses of a construction company.

An example of an estimate for corrugated roofing materials

To put it simply, the estimated cost is the sum of all funds required for the construction of any facility, calculated on the basis of project documentation. Accordingly, the estimate for installing a roof made of corrugated sheets is calculated on the basis of working drawings of the roof.

Estimate for a roof made of corrugated sheets - drawing up rules and standards

There are two main types estimate documentation- these are local estimates and local estimate calculations. Local estimates are compiled for certain types of work based on working drawings. Local estimates, Unlike local estimates, are drawn up in cases where the scope of work cannot be accurately determined during design and is clarified during the construction process.

The estimate for a roof made of corrugated sheets is quite a voluminous document, since it includes all types of work performed during the construction of the roof. These include:

• development technical documentation necessary for the installation of the roof, including the design of the work;
• installation of the roof truss system;
• installation of thermal and waterproofing;
• installation of the roofing itself;
• installation of ventilation and drainage systems;
• installation, if necessary, skylights;
• installation of cornice and gable overhangs;
• production and installation of various additional elements, including non-standard ones.

The basis for the development of estimate documentation is State elemental estimate norms (GESN). They reflect the industry average costs for various construction works, including the labor costs of workers and funds for operating machines and mechanisms.

Not required, but recommended

Although GESN standards are mandatory only for construction projects financed from the state budget, they are often used by designers to prepare estimate documentation for facilities for a wide variety of purposes.

Based on state elemental estimate standards, unit prices and consolidated standards are developed for various construction works. To develop estimates, you need high qualifications, knowledge of construction technology and the ability to use regulatory documentation.

Often, estimate standards do not contain direct prices for certain types of work. Thus, in the GESN standards, there is no roofing made of corrugated sheets over wooden sheathing. Therefore, for drawing up estimates, prices 12-01-020 and 12-01-023 for “Roof installation” are used various types from metal tiles." In this case, the nomenclature and consumption of main and auxiliary material resources are adopted in accordance with the design documentation.

As can be seen from the above, the estimate for a roof made of corrugated sheets is a rather complex calculation, which is not easy to carry out without the appropriate qualifications and experience. Therefore, individual developers often use different price lists of construction organizations.

An estimate is not always needed

Drawing up a full estimate for the roof of a corrugated roof of an individual residential building is often impractical due to the relatively small amount of work.

Basically, estimates for roofing work from corrugated sheets are drawn up for industrial facilities or large quantity work, for example, during the construction by one company of an entire cottage community or a large number of houses. In all other cases, cost tables are used and simple calculations by area.

The cost of installing a corrugated roof

Many construction companies For the convenience of customers, they post their own prices for installation of corrugated roofing on their websites. This can be either the cost of turnkey roof construction or prices for individual types of work. In this case, when calculating the costs of installing a roof made of corrugated sheets, the estimate will consist of the cost of installation work and the cost of materials.

Below is the estimated cost of installing a turnkey corrugated roof.

The above data will allow you to roughly determine the cost of building a roof. They can be calculated more accurately using the price list for different kinds works

The content of the article

Even for a private home, you need to draw up an estimate for roof repairs in order to know exactly how much this work will cost and, based on your financial capabilities, choose the appropriate materials. In the same way, estimates are drawn up for roof repairs in any organization that has buildings and structures on its balance sheet.

Before drawing up an estimate for repair work, it is necessary to analyze the condition of the roof, measure damaged areas. To do this, an inspection report is drawn up, and after this the data is transferred to the defective list, which indicates the necessary upcoming work and its quantity, the volumes of required materials, mechanisms, and devices. In addition to accurate calculations for roof repairs, the estimate contains unforeseen expenses.

Mandatory items in the estimate

In the first positions in the estimate, preparatory work, which include: dismantling a rolled roofing covering consisting of several layers;

• dismantling cement-sand screed;
• dismantling insulation, vapor barrier;
• dismantling parapets if necessary;
• dismantling water intake funnels or wall gutters;
• dismantling of various connections of the rolled carpet to the roof elements, etc.

After this, the estimate for the repair of the soft roof should continue with positions for restoration work, which will contain:

• installation of new parapets;
• treating the base with a primer;
• leveling screed; laying vapor barrier;
• laying insulation;
• arrangement of junctions of the roofing carpet to the vertical planes of the roof elements;
• installation of water intake funnels or gutters;
• repair or restoration of chimney and ventilation pipes;
• installation directly roofing material.

The estimate for a major roof repair is fundamentally different from the estimate for the current one, since it contains a more expanded list of work, larger volumes, as a result, the cost of a major repair is several times higher than the cost of a current repair.

The procedure for drawing up estimates

The list of repair work may vary depending on the selected materials or the use of new technologies, which should be reflected in the estimate. For example, when preparing an estimate for repairs metal roofing, work is envisaged to replace metal profile sheets, but no work is carried out to apply bitumen-containing materials.

The estimate includes work related to laying metal sheets, trimming and other work corresponding to this specificity. In addition to work on dismantling and restoring the roof covering, the estimate includes work related to the use of machinery - truck cranes, cars, lifts, etc. When repairing roofs on one-story buildings lifting mechanisms are usually not used. But vehicles may be used to deliver materials from the seller, and these costs are also included in the estimate.

For enterprises, estimates are made more expanded, which includes the cost of mechanisms, separately the wages of machine operators and construction workers, calculations calculated in man-days, overhead costs, correction factors, estimated profits and other points.

As a result, the estimate shows the total amount and since the estimate is a document, it must be signed by the preparer and the person who checked it. After this, the estimate is agreed upon between the customer and the contractor, approved and signed by both parties. In addition to the estimate itself, enterprises prepare various reporting documents necessary to record the repair work performed.

Examples of estimates for different types construction works can be found on the Internet. For example, DefSmeta, a program created by estimators, foremen, suppliers and enterprise managers, allows you to quickly draw up estimates in today's prices.

This will be accompanied by a list of necessary materials for repairs or construction, and a schedule for receipt of funds. When drawing up contracts, this system greatly simplifies and facilitates the work of concluding construction contracts. When drawing up an estimate, data on the volume of work is entered into the program, and within an hour the estimate will be ready.

Any roof, be it private or apartment building, periodically needs repairs. Any, even the slightest, violation of the roof’s tightness can lead to a leak occurring on the top floor. In order to carry out repairs correctly without shortages and excess consumption of materials, you need to draw up an estimate in which all restoration measures will be clearly calculated and the costs of them reflected.

Before drawing up the document, the condition of the roof is assessed and a report is completed, which reflects the results of the inspection. This data is transferred to the defect sheet and an estimate is drawn up based on it. This article covers the topic of estimates and presents a sample of them.

Mandatory items in the estimate

First of all, the estimate document always indicates measures to remove the old coating, which are carried out in several stages. This includes dismantling concrete screed, dismantling insulation and vapor barrier, dismantling parapets, if necessary, removing gutters and water intake funnels, dismantling the fastening of the top roof covering.

The next item will be the restoration of the surface, the list of which may increase or decrease depending on the condition in which the roof is:

• Installation of new parapets
• Applying primer to the base
• Screed alignment
• Laying a steam and heat insulation layer
• Installation of roofing material junctions on the sides
• Installation of new gutters and water inlets
• Restoration or installation of new ventilation and chimney pipes
• Installation of roofing material

The estimate for a major replacement will differ from the calculation document for the current one, since the first requires large amounts of work, often not just restoration, but complete replacement some areas.

Budgeting

First of all, it is necessary to determine exactly what type of roof will be restored: soft, metal, corrugated or some other. This is necessary to draw up the document in the order that depends on the materials and technologies used when roofing works. For example, for the repair of a metal roof made of corrugated sheets, the estimate will indicate the replacement of metal sheets and accompanying actions. There will be no article about covering with a bitumen layer, since there is simply none on such a roof.

Important! In addition to restoration, the document also includes the costs of delivering the cargo and lifting it onto the roof.

You also need to determine what type of restoration should be carried out: capital or current:

1. Estimate sheet for overhaul. If major roof repairs are needed, then a plan must be developed in advance project documentation the organization that has permission for this, that is, SRO approval for such construction work. The created project will become Starting point in creating an estimate for major roof repairs.
2. Estimate sheet for current repairs. The estimate is drawn up on the basis of a defect sheet, which is compiled by a technician after assessing the condition of the roof. Such estimates are also prepared by the company that is hired to carry out roof restoration work. management company. IN in this case It is not necessary for the company to have an SRO permit, since work on non-technically complex and non-hazardous facilities can be carried out without it.

The estimate sheet is official document and must necessarily have the signature of the person who compiled it, as well as the person who checked it. After it is drawn up, it must be agreed upon between the customer and the contractor and certified.

An example of an estimate for repairing a soft roof can be seen below:

Factors affecting cost

Compilation of this document It’s not a tricky matter, but some nuances can significantly change the cost of the work. These include:

• The area where work is to be carried out. Accordingly, the larger the damaged area, the large quantity materials need to be used and work needs to be done.
• The cost of sent materials on the market, which may vary depending on the supplier.
• Type of work performed: major or current repairs.
• The level of waste of the material used to restore the roof.
• The need to use additional equipment, for example, for lifting or transportation.
