Any roof, be it in a private or apartment building, periodically needs repair. Any, even the smallest violation of the tightness of the roof can lead to the fact that a leak will be observed on the upper floor. In order to make repairs correctly without a shortage and overspending of materials, you need to draw up an estimate in which all restoration measures will be clearly calculated and the costs for them are reflected.

Before drawing up the document, the condition of the roof is assessed and an act is performed, which reflects the results of the inspection. This data is transferred to the defective statement and based on it, an estimate is made. 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 for removing the old coating, which are performed in several stages. This includes dismantling the concrete screed, dismantling the insulation and vapor barrier, dismantling the parapets, if necessary, removing the gutters and water intake funnels, dismantling the fastening of the roof top covering.

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

• Installation of new parapets
• Applying a primer to the base
• Leveling the screed
• Laying the steam and heat insulation layer
• Installation of roofing material abutments on the sides
• Installation of new gutters and water inlets
• Refurbishment or installation of new ventilation and chimney pipes
• Installation of roofing material

The estimate for the capital replacement will differ from the settlement document for the current one, since the former requires large amounts of work, often not just restoration, but the complete replacement of some sections.

Budgeting

First of all, it is necessary to accurately determine the restoration of which roof will be needed: soft, metal-tiled, corrugated or some other kind. This is necessary in order to draw up a document in the order that depends on the materials and technologies used for roofing work. For example, for the repair of a metal roof made of corrugated board, the estimate will indicate the replacement of metal sheets and the accompanying actions. There will not be an article for covering with a bituminous layer, since it simply does not exist on such a roof.

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

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

1. Estimated sheet for overhaul. If a major overhaul of the roof is needed, then the project documentation must be developed in advance by the organization that has a permit for this, that is, an SRO permit for such construction work. The created project will become the starting point in the creation of an estimate for the overhaul of the roof.
2. Estimated sheet for current repairs. Estimating is based on a defective statement, which was drawn up by a technician after assessing the condition of the roof. Such estimates are also drawn up by the company that has been contracted to carry out the restoration of the roof by the management company. In this case, it is not necessary for the company to have an SRO permit, since work at technically non-complex and non-hazardous facilities can be carried out without it.

The estimate sheet is an official document and must be signed by the person who prepared it, as well as the person who checked it. After it is drawn up, it must be agreed between the customer and the contractor and certified.

An example of an estimate for the repair of a soft roof can be viewed below:

Factors affecting cost

Drawing up this document is not a tricky business, but some of the nuances can significantly change the cost of the work. These include:

• The area on which the work is to be carried out. Accordingly, the larger the damaged area, the more materials you need to use and work needs to be done.
• The cost of submissions on the market, which may vary from vendor to vendor.
• Type of work performed: major or current repairs.
• Waste level of the material used to rebuild the roof.
• The need to use additional equipment, for example, for lifting or transporting.

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 variety of reasons, primarily this:

• 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 repairs);
• type and cost of materials for arranging a roofing cake;
• the degree of damage to the coating and inner layers of the roofing cake;
• the scope of work (the elimination of local damages 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 when installing various materials. This makes it possible to avoid additional unexpected costs.

Budgeting

How to make an estimate for a roof repair? Usually, a defective statement is used to draw up an estimate with a detailed listing of the types and volumes of work required, the types and quantities of material required. 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 of 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.

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;
• deductions to the budget from the payroll fund;
• the cost of basic and auxiliary building materials;
• business expenses of a construction company.

An example of an estimate for materials for roofing from corrugated board

In simpler terms, the estimated cost is the sum of all funds required for the construction of any facility, calculated on the basis of design documentation. Accordingly, the estimate for the roofing device made of corrugated board is calculated on the basis of the working drawings of the roof.

Estimate for a roof made of corrugated board - compilation rules and norms

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

The estimate for the roof from the profiled sheet is a rather voluminous document, since it includes all types of work performed during the construction of the roof. These include:

• development of technical documentation required for the installation of the roof, including the project for the production of works;
• installation of the roof truss system;
• installation of heat and waterproofing;
• installation of the roofing itself;
• installation of ventilation and drainage systems;
• installation, if necessary, of roof windows;
• installation of cornice and pediment overhangs;
• manufacturing and installation of various additional elements, including non-standard ones.

The basis for the development of estimate documentation are State Elemental Estimated Norms (HPES)... They reflect the average industry costs for various construction works, including the labor costs of workers and funds for the operation of machines and mechanisms.

Optional but desirable

Although the HESN standards are mandatory only for construction projects financed from the state budget, they are often used by designers to prepare estimates for objects of various purposes.

On the basis of state elementary estimate norms, unit prices and consolidated norms are developed for various construction work. To develop estimates, high qualifications, knowledge of construction technology and the ability to use regulatory documents are required.

Often in the estimated rates there are no direct prices for some types of work. So in the norms of the HESN, there is no roof made of corrugated board on a wooden crate. Therefore, for the preparation of estimates, the prices 12-01-020 and 12-01-023 are used for "Roofing of various types from metal tiles." In this case, the nomenclature and consumption of the main and auxiliary material resources are accepted in accordance with the project documentation.

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

An estimate is not always needed

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

Basically, an estimate for roofing work from corrugated board is drawn up for industrial facilities or a large number of works, for example, when one company is building an entire cottage village or a large number of houses. In all other cases, cost tables and simple area calculations are used.

The cost of work on the construction of a roof made of corrugated board

For the convenience of customers, many construction companies post their own prices for the installation of corrugated roofing on their websites. This can be both the cost of building a "turnkey" roof, and prices for certain types of work. In this case, when calculating the cost of roofing from a profiled sheet, the estimate will consist of the cost of installation work and the cost of materials.

Below is the approximate cost of installing a roof made of corrugated board "turnkey".

The above data will allow you to roughly determine the cost of building a roof. More accurately they can be calculated using the price list for various types of work.

Snow and wind loads are included in the calculation of the roof. A carefully thought-out roof structure and the angle of inclination of the slopes will ensure unhindered snow cover in winter, and will evenly distribute the weight of the rafter system on the load-bearing walls.

The most common types of roofing:

• Shed. This is the simplest and most economical design option, which is suitable for small garden, country and guest houses.
• Gable. A roof with two slopes and large overhangs is most often chosen by owners of country cottages with an area of ​​60-80 m2.
• Hip. Four-pitched roofs with two trapezoidal and two triangular slopes are used due to their reliability and excellent external characteristics.
• Shatrovaya. The four ramps of a triangular shape are connected at the top point. Flawlessly executed installation and correct selection of materials guarantee durability and an attractive appearance of the roof.
• Mansard room. The upper slopes have a gentle slope, while the lower ones are steep. There is enough usable space under the sloping roof for arranging an additional bedroom or study.
• Dome and conical. Intricate vaulted structures with domes and turrets look very nice on large country houses with level differences.

Our craftsmen have extensive experience in the installation of all types of materials for installation and roof insulation, both traditional and new. We have the most favorable prices for roofing works, we give a long-term guarantee for all types of installation.

When calculating the cost, the estimate includes the following roofing work - preparation, installation of the rafter system, insulation, roof cladding and filing, installation of the drainage system. A fixed price list for roofing works eliminates overspending of materials and allows you to accurately meet the planned budget.

I used the services of the master builder Ilya for the construction of a bathhouse at my summer cottage. I was very pleased with the work performed, since he is really a professional with a capital letter, all my wishes were taken into account, and the structure itself was built strictly on time!

My mother advised me to use Ilya's services, since last year his specialists made repairs to her in the kitchen, and she was very delighted. I liked the fact that all types of work and their cost are registered on the site, that is, you can calculate in advance how much this or that service will cost you.

They made a carport for us next to the company's office. Of course, we designed everything on an individual basis, since it was necessary to equip a large area, and the guys completely coped with their task. The result is a very beautiful cellular polycarbonate dome that goes well with the building itself.

Even for a private house, it is required to draw up an estimate for roof repairs in order to know exactly what this work will cost and, based on your financial capabilities, to choose the appropriate materials. In the same way, an estimate for the repair of the roof is drawn up in any organization that has buildings and structures on its balance sheet.

Before making an estimate for repair work, it is necessary to analyze the condition of the roof, measure the damaged areas. For this, an inspection report is drawn up, and after that the data is transferred to the defective statement, which indicates the necessary forthcoming work and their number, the amount of required materials, mechanisms, devices. In addition to accurate calculations for the repair of the roof, the estimate contains unforeseen expenses.

Mandatory articles in the estimate

In the first positions in the estimate, preparatory work is prescribed, which include: disassembling a roll roofing covering, consisting of several layers;

• dismantling of 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.

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

• installation of new parapets;
• primer treatment of the base;
• leveling screed; laying vapor barrier;
• laying insulation;
• the device of abutting the roofing carpet to the vertical planes of the roof elements;
• installation of water intake funnels or gutters;
• repair or restoration of chimney, ventilation pipes;
• installation of the roofing material itself.

The estimate for the overhaul of the roof is fundamentally different from the estimate for the current one, since it contains a more extended list of works, large volumes, as a result, the cost of capital repairs exceeds the cost of current repairs several times.

Estimation procedure

The list of repair works may vary depending on the selected materials or the use of new technologies, which should be reflected in the estimate. For example, when drawing up an estimate for the repair of a metal roof, work is envisaged to replace metal profile sheets, but at the same time work is not performed on the application of bitumen-containing materials.

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

For enterprises, estimates are made more extended, where the cost of mechanisms is laid down, separately the wages of machine operators and construction workers, calculations calculated in man-days, overhead costs, correction factors, estimated profit 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 compiler and the person who checked it. After that, the estimate is agreed between the customer and the contractor, approved and signed by both parties. In addition to the estimate itself, the enterprises draw up various reporting documents necessary to account for the repair work done.

Examples of estimates for different types of construction work can be found on the Internet. For example, DefSmeta, a program created by estimates, supervisors, suppliers and business leaders, allows you to quickly make an estimate in today's prices.

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