How to make an estimate for roofing work. Drawing up an estimate for the repair of the roof: the procedure. Mandatory items in the estimate

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 building materials market, 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?

The estimate for the repair of the roof, at the preparatory stage, has a very important stage - the inspection of the condition of the roof with the measurement of the 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 current repairs, 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;
• the procedure for replacing damaged roof sections;
• devices, mechanisms and the required amount of materials necessary for carrying out these works.

IMPORTANT! For the production and elimination of defects of soft roofs, roofs made of metal or corrugated board, as well as for work that does not affect the safety of a building or structure, an SRO permit for a company / organization involved 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 it is already a prerequisite for the company / organization to 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 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.

• 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 capital 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 the corresponding materials for the repair are selected, which cannot but be reflected in the preparation of the estimate. For example, the estimate for the repair of a metal roof from a profiled sheet will fully reflect the entire list of work related to the replacement of metal profile sheets: laying metal sheets, cutting them, and 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.

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.

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. A correctly made estimate for major repairs 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:

• Roofing type... Different roofing materials cost differently, and therefore the price of repairing a soft roof will differ significantly from the cost of restoring slate or tile coverings. Again, depending on the type of coating, the price of installation work will differ;
• 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. Access roads 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
	Repairing a 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 the installation of fusion patches over the damaged old pavement.
	Slate roof repair... Such work is required either after the expiration of the resource of the material, or as a result of local damage and the formation of leaks. Overhaul includes dismantling the slate, inspecting the rafter system for damage and laying a new coating. Local elimination of leaks is performed by replacing one damaged sheet or by sealing cracks.
	Reconstruction of seam roofing... The metal coating, subject to correct installation, is 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... The average price of materials and related products is indicated. 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 growth 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 projects 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 accuracy what materials and in what quantity to buy, so that there is no surplus left at the end of the repair.
	Competent planning of actions... 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 major and current roof repairs. If you have any questions about determining defects in roofing and calculating, write about this in the comments to the article.

If you want to express gratitude, add clarification or objection, ask the author something - add a comment or say thank you!

The topic of the article is an estimate for the repair of the roof. Any process carried out by a contractor, which is repair or maintenance of buildings and structures, must ultimately be paid for. The basis of payment is the estimate, which is attached to the contract, as an integral part of it. That is, it is a fundamental document, in which it is described point by point, for what operations and how much the customer must pay. In the article, we will talk about how to make an estimate, on what basis, and also give several examples of making estimates for a roof covered with different roofing materials.

What is the estimate

As mentioned above, this is a document necessary for accounting and for planning activities. It clearly describes the construction operations that will be carried out during the repair work, plus the required amount of materials. In addition, based on the estimate, you can easily plan the time spent on roof repairs. Of course, you will have to take into account some factors and accept them as amendments.

On the basis of which this document is drawn up

There are several criteria that go into drawing up a repair estimate for a roof:

What kind of roofing material is the roof covered with? It is clear that the variety of roofing dictates the budget allocated for its repair. For example, an estimate for repairing a soft roof will be cheaper than repairing a roof covered with ceramic tiles. The reason is the different price of products, some of which will have to be replaced during the repair operations.

The degree of damage to the roof. For example, if a building has been in operation for a long time, then most likely its roof has undergone significant wear and tear. This means that the roofing material will have to be replaced in whole or in part. If the house has been in operation for no more than 10 years, then the repair will result in the replacement of several elements, which will be much cheaper in cost.

Roof structure dimensions... Everything is clear here: the larger the roof area, the more materials, time and effort will be spent.

Location of the building... If it is within the city limits, then transport costs will be minimal. If the house is located far from the contractor's base, then the customer will accordingly have to pay for the transportation of building materials and people.

Season also an important factor affecting the budgeting. In winter, all work is more difficult to carry out, which means that the price will be higher.

How to make an estimate for repair work

It all starts with the arrival of a specialist at the facility. He must inspect the roof structure and determine the amount of work to be done. On the basis of its inspection, a defective act is drawn up. This document indicates the condition of the roof, its wear, the number of defects and flaws, the dimensions of the roof structure. And also whether it is required to carry out only repairs or complete reconstruction. Be sure to indicate the type of roofing material, the structure of the rafter system and the battens in the defective act. That is, a specialist must fully analyze the roof and determine its technical condition.

It is this document that forms the basis for the preparation of the estimate. Let's look at several roofing coverings as an example, and the first will be an estimate for soft roofing.

If we speak in terms of articles, then the first item in the estimate indicates dismantling work:

removal of roofing;

removal of screed from cement-sand mortar;

dismantling the insulating cake;

if necessary, include the dismantling of the parapets;

partial dismantling of the drainage system, this mainly concerns the receiving funnels and gutters located under the eaves;

dismantling of the abutment sections.

On our website you can find contacts of construction companies that offer services roof design and repair... You can communicate directly with representatives by visiting the Low-Rise Country exhibition of houses.

It is clear that not all items will be included in the repair estimate. This is a complete list of works, some of which may be included, because they are not recorded in the defective act.

The second point is articles related to restoration work:

construction of parapets;

repair of the roof base: sealing cracks, cracks and other things;

primer treatment;

restoration of the heat-insulating cake with the arrangement of protective layers: steam and waterproofing;

filling the screed;

installation of roofing material, taking into account the areas of abutment.

Note that the overhaul of the roof is much different from the current one. For example, if a pitched roof is being repaired, on which, for example, bitumen shingles have been laid, then the capital re-equipment includes the repair of the rafter system and solid sheathing. And this is a large financial investment for the purchase of building materials and huge labor costs.

We add that the list of works related to the repair of the roof may vary depending on the used roofing material, as well as the use of the latest technologies. For example, if the soft roof is replaced with a metal covering. Here, the repair consists only in the dismantling of the rolled roof and the installation of the metal coating without the use of hot technologies and bitumen adhesive composition.

And one more criterion that must be taken into account when making an estimate of repair work. This is the use of a special technique. This is very important when carrying out repairs on the roof of multi-storey buildings. And the higher the house, the more you will have to pay for the equipment in use. In this regard, the repair of the roof structure of a one-story building is much cheaper. After all, almost all building materials are raised manually.

Generalization on the topic or what is indicated in the estimate form

So, summarizing all of the above, we can conclude that the estimate for repair work on the roofs of residential, industrial and administrative buildings consists of the following positions:

List of repair work. That is, the points indicate the sequence of construction operations and the volume of each of them.

The amount of building material required by type and type.

The price of the required building materials. There is one point here. If exact prices are indicated, it is necessary to attach documents from suppliers (invoices or delivery notes) to the estimate.

Prices for the work performed.

Correction factors must be indicated. This indicator indicates how much the price of building materials and services can rise. You will definitely have to prove the reasons for the growth in cost indicators.

At the end of the document, the total amount that the customer must pay for the repair work is indicated.

Pay attention to the photo below, which shows part of the estimate for a roof made of corrugated board (example), which shows the correction factors and the total estimated cost of repair work.

And the last thing. An estimate is a document that carries a legislative burden. Therefore, it is signed from two sides: the customer and the contractor. The first one agrees with what is displayed in the document, and accordingly with the price. The second one offers the type of work, their volume and the money that he asks for the provision of this service. If the contractor fails to perform any operations, but who has received payment for this, may be brought to court on the basis of the estimate and contract.

We add that not all owners of private real estate require the manufacturer to submit an estimate. And this is a big mistake, which can lead to an overspending of the budget allocated for the repair of the roof structure. It will be almost impossible to prove non-fulfillment or poor-quality execution of construction processes without this document.

But there are other positive aspects of the presented paper:

can objectively estimate the complexity of future repairs;

exactly to acquire required building materials without overspending or shortages;

competently to plan the whole process from start to finish.

Let's show an example of an estimate for a seam roofing of a private house. What should be displayed in it. First of all, the area of ​​the roof covering that needs to be repaired is displayed. Plus the cost of sheet metal or seam roof paintings per 1 m². And the number of fasteners must be added.

If it is required to repair the rafter system or lathing, then indicate how much lumber should be replaced or repaired, as well as the cost of the repair service itself. If the roof is insulated, then work related to the repair of the heat-insulating cake is included in the estimate.

Be sure to indicate planned savings and overhead costs in the estimate for repairing the roof of a private house, which partially cover the additional costs of the contractor. And at the end, the total amount to be paid is displayed, which is called the estimated.

Video description

In general, it is impossible to make an estimate without special knowledge. Therefore, for example, we want to invite you to watch a video in which a specialist shows how to make an estimate for repairing a soft roof:

Conclusion on the topic

The estimate for the repair work is a document that confirms the budget allocated for this event. He is the basis of payment, he is the basis of disputes. Therefore, before signing any papers, and even more an estimate and a contract, the customer must understand them. That is, you cannot sign both documents without reading it. Special attention to the final amount. If it suits you, then there is no problem.

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 transportation.
