Roof repair estimate: how to make it yourself

An estimate for roof repairs is needed when planning roof repairs for apartment buildings, industrial and other buildings, the maintenance of which is associated with accounting... Correctly compiled estimate for overhaul allows you to calculate in advance the cost of the necessary materials and calculate the budget for the upcoming event. In addition, with proper planning, it is possible to determine in advance the time that will be required from the start of the repair to the commissioning of the roof, adjusted for various factors affecting the completion time.

What determines the repair estimate

Budgeting is determined by the following criteria:

• Type of roofing ... Different roofing materials cost differently, and therefore the cost of repair soft roof will differ significantly from the cost of refurbishing slate or tile coverings. Again, depending on the type of coverage, the price will differ installation works;
• The degree of damage to the roofing... Strong wear of the roofing will result in its complete replacement, while minor wear will require local, and therefore less expensive, repair;
• Roof dimensions... The larger the roof, the more roofing material or slate, the time and effort required for roofing work;
• Features of the delivery of materials... The ability to purchase repair supplies near your home will simplify shipping and save time and money. The presence of driveways to the house will make unloading more convenient;
• Season... It is easier to repair the roof with your own hands during the warm season than during the cold season. The experts are of the same opinion, and therefore the price of work in summer and winter will be different.

Illustrations	Repair types according to the type of roofing
	Fix soft roof ... There are major and seasonal repairs. In the first case, the old material is dismantled with the restoration of the floor and the laying of a new roll roof. Together with the flooring of the material on the floor, the adjoining of the roof and various superstructures, parapets, etc. is performed anew. Seasonal refurbishment involves installing fusion patches over the damaged old pavement.
	Repair slate roof ... Such work is required either after the expiration of the material resource, or as a result of local damage and the formation of leaks. Overhaul provides for the dismantling of the slate, inspection rafter system for damage and new flooring. Local elimination of leaks is performed by replacing one damaged sheet or by sealing cracks.
	Restoration of seam roofing... Metallic coating provided correct installation durable, and therefore restoration may be required only after the expiration of the resource, that is, not earlier than 15-25 years after installation. As a preventive measure, corrugated seam roofing can be painted to prevent corrosion.
	Metal roofing repair... Structures covered with metal tiles are durable and reliable, and therefore repair may be required only after the expiration of the resource, when the entire coating is replaced with new roofing material.

What does the estimate form take into account?

In the estimate form, which is drawn up when organizing repair work on residential, industrial, administrative and other buildings, the following positions are spelled out:

• List of upcoming works... The volume and sequence of the upcoming work is determined in accordance with the previously compiled defective statement;
• Number of materials and units of measure... The name and quantity of materials, determined in accordance with the defective list, are indicated;
• Estimated price of materials... Indicated average price materials and related products. When specifying the exact numbers, you must refer to the trade organization;
• Estimated cost of works... The form indicates the average price of work, or exact numbers with reference to the organization providing the services;
• Correction factor. Simply put, it indicates how much the cost of repairs can rise and the reason that this increase can be due;
• Estimated price in rubles, indicating the time of the calculation... That is, the total amount of money is indicated, which is relevant at the time of the calculations.

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

A defective statement or a defective act is a document that contains a list of all damages that will have to be repaired in the course of the upcoming work. Determination of the damage that will be included in the defect report is carried out by experts.

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

Benefits of budgeting for roof repairs on private property

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

Illustrations	Reasons for budgeting for self-repair
	Objective assessment of the complexity of the upcoming work... Getting started, 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 cost overruns and lack of materials... Having made the correct estimate, you can decide with high precision what materials and in what quantity to buy, so that there is no surplus left at the end of the repair.
	Competent action planning... By planning your actions, you can get the job done on time, without stretching it out until the weather hits.

Let's summarize

Now you know why you need an estimate for capital and Maintenance roofs. If you have any questions about determining defects in roofing and calculating, write about this in the comments to the article.

A lot of enterprises, organizations and just individuals collide. At the same time, already at the very beginning of the process of organizing repair work, quite natural questions arise: how to determine the expected scope of work as accurately and in detail as possible, what materials to choose and, in the end, how to correctly estimate the repair of the roof in order to understand how much the proposed repair work and be able to clearly justify it before the decision-makers on the allocation of funds for these works?

Only one person can answer all of the above questions - the estimator, and his qualifications must be confirmed by the relevant documents (certificates). Only he, knowing all the subtleties of roofing work, the nuances of the market building materials will be able to lay down in the estimate documentation the implementation of the necessary volumes of roofing work with the required quality at the optimum for the customer.

Maintenance or overhaul?

Roof repair estimate, for preparatory stage, has a very important stage - inspection of the condition of the roof with the measurement of damaged areas and the subsequent preparation of the roof inspection report. And already on the basis of an analysis of the volume of revealed damage to the roofing, a decision is made on what kind of repairs need to be carried out: or.

In preparation for the current repair, an estimate for roof repairs is drawn up on the basis of a defective statement (bill of quantities), which reflects:

• the degree and amount of damage to the roof;
• procedure for replacing damaged roof sections;
• necessary for carrying out these works, devices, mechanisms and the required amount of materials.

IMPORTANT! For the production and elimination of defects of soft roofs, roofs made of metal or corrugated board, as well as for carrying out works that do not affect the safety of a building or structure, an SRO permit for a company / organization engaged in the preparation of estimates and PPR does not need to be issued.

To prepare for the roof, they are preparing for the proposed types of work, which will become the basis for drawing up an estimate, and here already a prerequisite the company / organization must have an SRO permit for these types of work. Project documentation also includes PPR.

Roof repair estimate: drawing up procedure

First of all, the estimate for the repair of the roof contains preparatory work, including:

• disassembly of roll roofing, consisting of several layers;
• dismantling the cement-sand screed;
• disassembly of insulation, vapor barrier;
• disassembly of parapets (if necessary);
• dismantling of water intake funnels or wall gutters;
• dismantling of various abutments of rolled carpet to roof elements, etc.

• data on the construction of new parapets;
• primer treatment of the base;
• the scope of work on the device of the leveling screed;
• laying vapor barrier and insulation;
• arrangement of abutments of the roofing carpet to the vertical elements of the roof;
• installation of water intake funnels, gutters;
• repair or restoration of chimney and ventilation pipes;
• installation, directly, of a new roofing carpet.

The estimate for roof repair (capital), containing both a larger volume of work and an expanded list of them, is fundamentally different from the estimate for current repairs. Naturally, the volume of costs for major repairs exceed the costs of current repairs by several times.

What else should the estimate for roof repairs contain?

Depending on the type of roof to be repaired, technologies and materials corresponding to them for the repair are selected, which cannot but be reflected in the preparation of the estimate. For example, in the estimate for repairs metal roof from the profiled sheet, the entire list of works related to the replacement of metal profiled sheets will be fully reflected: metal sheets, their trimming, other work related to this specificity.

In addition to dismantling and restoring the roofing, the estimate, if necessary, will include the use of various mechanisms, truck cranes, cars, lifts, etc. When repairing the roofs of one-story buildings, lifting mechanisms are usually not used.

Structural damage to the roof structure of a building is a serious problem requiring immediate action. If damage to the roof was found, then first of all it is required to fix them by drawing up a special document, on the basis of which an estimate for carrying out repair work will be drawn up in the future. It is about her that will be discussed below. The rules for its preparation and a sample estimate for repairs will be presented below.

As mentioned above, the repair estimate is based on the defective statement. The reason for its filling is the failure of the roof for any reason: from the end of the service life (natural deterioration of roofing materials), and ending with the results of mistakes made during the installation work.

If we are talking about a private cottage or country house, but it is planned to carry out repairs with the involvement of third parties, then in order to get acquainted with the volume of upcoming work and expenses, you should call a specialist. He will estimate the cost of the renovation with high precision. This approach makes it possible to optimize the costs of construction work, the performance of which is necessary to perform emergency, current or major repairs.

Residents apartment building you need to act on the same principle. But at the same time, the evaluator must be an employee management company, which is responsible for the maintenance of the house. Thus, in order to call a specialist, you need to submit a collective application.

The technician will record all existing defects and enter them into a special form, which, among other things, indicates the measures necessary to solve the existing problem. Often photographs are attached to the form describing the existing defects.

“It should be understood that the estimate for the repair work is formed on the basis of the information present in the defective statement. In this regard, its compilation should be taken as responsibly as possible. "

Repair price

The prices for the overhaul of the roof directly depend on a number of parameters:

• the total roof area, and as a result, the amount of work. The larger the roof area needs to be repaired, the higher the repair cost;
• the type and price of materials required for the arrangement roofing cake;
• the level of damage to coatings and elements under the roof (thermal insulation, waterproofing, etc.);
• scope of work. For example, the elimination of local damage will be much cheaper than overhaul;
• prices for the delivery of materials;
• wages of workers, which is calculated taking into account the complexity of the process and the specifics of the installation of roofing materials;
• payment for the use of specialized tools and equipment, if there is a need for their use.

“Budgeting should be done by an experienced technician. This is due to the fact that it is required to take into account a lot of different nuances: from the peculiarities of using a special tool, and ending with the consumption of roofing materials. You can have on hand various examples of compiled estimates, but all the subtleties still cannot be taken into account. In this regard, such work should be trusted by estimators. Such a professional approach allows you to avoid additional unforeseen expenses. "

Budgeting

As a rule, to draw up an estimate, a defective statement is used, containing a listing of the types and volumes of activities requiring implementation. In addition, it contains information on the amount of materials required. An estimate is required in order to convert the data available in the troubleshooting into a monetary equivalent. Thanks to this, it turns out to calculate the full cost of carrying out repair and restoration work. Estimated documentation is drawn up with the obligatory indication of the following values:

• serial number of the document. For the most part, this component of the estimate is of relevance for reporting;
• numerical and letter designations of resources (codes), and numbers of standards;
• the names of the works and the exact costs of their implementation;
• units of measure. For materials, this can be kilograms, grams, tons, or pieces. For workers, labor hours. For machinery, engine hours. For other resources, kilowatts, liters, etc .;
• number of units;
• unit prices in national currency;
• correction factors. It should be understood that no estimate can be made without errors;
• conversion factors;
• coefficients of the winter rise in price;
• total cost in national currency.

A competently drawn up estimate for the repair of the roof should contain a calculation of the price for carrying out preparatory measures. This is because repairs cannot start immediately after the problem is detected. First you need to dismantle the failed roof elements. In number preparatory work you need to include activities that need to be carried out on a roof of one type or another. For example, dismantling a multilayer roll coating involves a number of the following works:

• development of layers of roofing;
• dismantling the roof screed. Be sure to indicate whether it is reinforced. In this case, additional dismantling activities will be required using specialized equipment;
• disassembly of vapor barrier, waterproofing and thermal insulation layers;
• dismantling of parapets;
• disassembly of the system responsible for draining the water. We are talking about wall gutters, weirs and other structures of this type;
• dismantling of roll contact areas roofing material to vertical structures such as pipes stove heating or ventilation.

After that, in the estimate sheet, you need to indicate the positions of recovery measures. They can be very different. An example of work for a roof from a soft roof is as follows:

• arrangement of parapets;
• treatment of the roof with a primer;
• installation of heat-insulating, waterproofing and vapor barrier layers;
• filling the screed;
• installation of roof sections adjacent to vertical roof elements;
• arrangement of the drainage system;
• repair or complete restoration of ventilation, chimneys and other structural elements roofs;
• installation of finishing roofing material.

“The procedure for specifying work in the estimate directly depends on the type of roofing and the specifics of the materials used. Roof repair can mean restoration of waterproofing, complete replacement of the topcoat with a new one, etc. In this regard, each estimate is individual. "

After all the required data are entered into the estimate documentation, the costs are calculated for each item (material, types of work, etc.). After that, the total amount of money spent is calculated. The estimate for the repair of the roof is official document... In this regard, it must be certified by the originator and the person who checked it.

After checking, estimate documentation sent for approval and approval by the responsible person. If it comes on the repair of the roof of an apartment building, then the person in charge is the head of the management company. When it comes to private property, the owner is the person in charge.

Additionally, it should be said that the estimate is the most detailed document. Everything in it should be described as accurately as possible. In this document, it is impossible to indicate the repair of the roof in the column "title of work". Absolutely everything should be indicated in this paragraph: from loading and unloading works, and ending with each type of installation and dismantling. This also applies to other points.

After agreement with the person in charge, the estimate documentation is multiplied and attached to the roof repair contract. A sample estimate must be issued to the contractor for the repair and restoration work without fail. It is the estimate documentation that is most often the determining factor in concluding a contract for the implementation of construction and installation work.

Violation of the integrity of the roofing is a serious problem that requires an immediate solution. After fixing all damage to the roofing pie in the corresponding document, an estimate is drawn up for the repair of the roof, a sample of which is given at the end of this article.

Multi-family and private houses

Roofing can fail for a number of reasons, primarily:

• the end of the service life (natural wear of the material);
• accidental mechanical damage to the coating;
• defects in roofing material;
• the result of improper installation.

If we are talking about a private house, it is recommended to call a specialist to determine the condition of the roof and the amount of work to be done. He will help to estimate the required financial investments and draw up a detailed estimate. This approach allows you to optimize the costs of emergency, current or major repairs.

Whatever house you live in, in a private or multi-apartment, the roof periodically needs repair work. After all, damage to the coating can lead to the fact that the premises located below will suffer. And in order to start repairing, you must first estimate their cost and material consumption. For this, an estimate is made for the repair of the roof.

First of all, it is worth paying attention to what kind of roof repair is needed: soft, from corrugated board or metal, because the composition and its order largely depends on the technologies and materials that it was decided to use. The second question, the answer to which is determined after analyzing the damage, is what repairs need to be performed - current or major?

1. Creation of estimates for current repairs

Often, the preparation of estimates, as well as the PPR is carried out construction company or an organization that, in addition to determining the cost, has an SRO approval. Although, regarding the last point, there is a clear indication that work on current repairs that take place at non-hazardous and technically not complex facilities do not require SRO approval.

Repair of a soft roof of a multi-storey building

Important!

In addition, there is a list of types construction works for which the company does not need to obtain an SRO admission. It includes current repairs and elimination of defects of a soft roof, metal roofing, corrugated board, as well as a number of works that will not affect the safety of the house.

In this case, estimates are made on the basis of a defective statement, which shows the degree of damage to the roofing.

Defective list for the current repair of the roof

1. Creation of estimates for major repairs

If a major overhaul is necessary, first of all, it is necessary to involve an organization that will develop design documentation for this type of work. A prerequisite is the availability of an SRO permit for this type of construction work. Based on the project documentation, which provides for technical inspections, PPR is the starting point for creating estimates for repairs.

What must be shown in the cost calculation?

The data for creating the calculation is the defective statement, and in the case of overhaul - project documentation, which includes additional items (in particular PPR, survey data, etc.). At the same time, you need to understand that the second option is much more expensive than current repairs.

Repair estimates

The calculation of the cost of repairing a roof made of corrugated board often includes the following points:

• The preparatory stage, which will include work on the removal of corrugated board, disassembly of vapor barrier and insulation, parapets (if necessary), etc.
• The second stage is the restoration of the coating, which will include work on the preparation of the base, the installation of new parapets (if the old ones were dismantled), the device of a vapor barrier, the installation of corrugated board, as well as restoration work with chimneys and ventilation devices.

Local estimate for roof repair

Calculations for the repair work of metal roofs are not very different. In any case, both stages (preparatory, when the old coating is dismantled, and restoration) pass. The difference lies in the materials and mechanisms used. In this case, it is necessary to take into account the fact that when installing a roof made of metal tiles, it is necessary to take into account a sufficiently large level of waste.

Estimated calculation for roof repair

What will the final cost of the work depend on?

Although the procedure for drawing up is quite simple, some details can significantly affect the final cost of the work.

Roof repair cost estimate

The most "traditional" factors to which attention must be paid are:

• The area of ​​the room, roof. You need to understand that the larger the damaged surface, the more materials, labor of workers and mechanisms will be involved.
• The estimate takes into account the rate of consumption of materials, but their cost on the market may be different, which also needs to be kept in mind.
• Type of work: overhaul of both the roof and any other room will be much more expensive than removing a few bulges.
• Waste level of the selected roofing material.
• Need to use lifting mechanisms and other machines (in buildings and structures with one floor, they are usually not taken into account).

Roof reconstruction estimate

It's hard enough to fully estimate what the final amount will be that will need to be paid for roof repairs. Therefore, even when drawing up the most detailed calculation, you need to remember about the possibility of additional costs.

Roof repair estimate - detailed repair plan

Important!

The creation of estimates for repair work on the roof depends on several factors. First of all, you need to determine how much the coating is damaged and what kind of repairs will need to be performed - current or major.

In the first case, only a defective statement is needed to calculate the estimate. In the second, it is necessary to involve an organization that has access to an SRO, will develop a PD, on the basis of which the calculation will be made.

How to make an estimate for the repair of a soft roof

Violation of the integrity of the roofing is a serious problem that requires an immediate solution. After fixing all damage to the roofing pie in the corresponding document, an estimate is drawn up for the repair of the roof, a sample of which is given at the end of this article.

Multi-family and private houses

Roofing can fail for a number of reasons, primarily:

• the end of the service life (natural wear of the material);
• accidental mechanical damage to the coating;
• defects in roofing material;
• the result of improper installation.

If we are talking about a private house, it is recommended to call a specialist to determine the condition of the roof and the amount of work to be done. He will help to estimate the required financial investments and draw up a detailed estimate. This approach allows you to optimize the costs of emergency, current or major repairs.

Residents of apartment buildings should follow the same scheme, but the damage assessor should be a representative of the management organization responsible for the maintenance of the building. To call a technician to assess the condition of the roof, a written application is required to the management organization. A technician inspects the roof and apartments of the upper floors, affected by rain or melt water, and records in detail all existing damage in a defective statement. It is recommended to include photographs of the damage. The same document indicates the necessary measures for the restoration of structures and the roofing pie.

The estimate for the repair is formed on the basis of the defective statement, therefore, it should be filled out with the utmost care.

Repair cost

The estimate for the overhaul of the roof makes it possible to assess the level of upcoming financial investments, to avoid cost overruns. The cost of the planned roof repair works depends on the following parameters:

• the total area of ​​the roof (the larger the area, the more expensive the repair is);
• type and cost of materials for arranging a roofing cake;
• the degree of damage to the coating and inner layers roofing cake;
• the scope of work (the elimination of local damage will cost significantly less than a major overhaul);
• the cost of the materials themselves and their delivery;
• remuneration of workers, taking into account the labor intensity and specifics of the installation of the materials used;
• payment for the use of special equipment (if necessary, its use).

Budgeting requires a professional approach, since it is necessary to take into account the peculiarities of use and consumption during installation various materials... This makes it possible to avoid additional unexpected costs.

Budgeting

How to make an estimate for roof repairs? Usually, a defective statement is used to draw up an estimate with a detailed listing of the types and volumes of work required, types and quantities. required material... An estimate is needed to translate this data into a monetary equivalent, which allows you to calculate the cost of repairs.

The estimate is drawn up with the obligatory indication:

• serial number;
• resource codes and rate numbers;
• titles of work and costs for their implementation;
• units of measure;
• number of units;
• unit cost (in rubles);
• correction factors;
• conversion factors;
• coefficients of winter increases in prices;
• total costs (in rubles).

A sample estimate for roof repairs should contain a calculation of the cost of preparatory work. These may include:

• disassembly of multilayer roll roofing;
• dismantling the screed;
• disassembly of heat insulation and vapor barrier layers;
• dismantling of parapets;
• dismantling the drainage system (wall gutters, drainage funnels);
• dismantling of roof junctions to vertical structures.

• the device of parapets;
• treatment of the base of the roof with a primer;
• laying vapor barrier and thermal insulation layers;
• arrangement of screed;
• the device of abutting the roofing to the vertical roof structures;
• installation of a drainage system;
• restoration or repair of ventilation and / or chimneys;
• installation of finishing roofing.

The order of work depends on the type of roof and the type of materials used. Roof repairs may involve restoring the waterproofing layer and completely replacing the topcoat with a new one.
