Roofing. How to make an estimate for roofing work sample. Roof repair estimate and its sample Example of a roof overhaul 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 renovation work and be able to clearly justify it before the decision-makers on the allocation of funds for these works?
Roof repair estimate: BTA Group of Companies offers
Only one person can answer all 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.
Current repair or overhaul?
Roof repair estimate, for preparatory stage, has a very important stage - inspection of the condition of the roof with 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 about what kind of repairs need to be carried out:
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;
- 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 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 includes PPR.
Roof repair estimate: drawing up procedure
First of all, the estimate for roof repair contains preparatory workincluding:
- 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 inlet 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 adjoining roofing carpet to vertical roof elements;
- installation of water intake funnels, gutters;
- repair or restoration of chimney and ventilation pipes;
- installation, directly, of a new roofing carpet.
The estimate for the repair of the roof (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 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 works related to the replacement of metal profile sheets: laying metal sheets, cutting them, and other work related to this specificity.
In addition to works on dismantling and restoration of 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.
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 which 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.
Based on what 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 repairs soft roof will be cheaper than repairing a roof covered 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.
Dimensions roof structure ... 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 transportation 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 influencing 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 in the defective act roofing material, construction rafter system and lathing. 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 take a few roofing coverings as an example, and the first one will be an estimate for soft roofing.
If we speak by article, then the first item in the estimate indicates dismantling work:
removal of roofing;
removal of the screed from the cement-sand mortar;
dismantling insulating cake;
if necessary, include the dismantling of the parapets;
partial dismantling drainage systemthis mainly applies to receiving funnels and gutters located under the eaves;
disassembly of junction areas.
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 exhibition of houses "Low-rise Country".
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 thermal insulation cake with the arrangement of protective layers: steam and waterproofing;
filling the screed;
installation of roofing material, taking into account the junction areas.
Note that overhaul the roof is much different from the current one. For example, if renovation is in progress pitched roof, on which, for example, bitumen shingles are laid, then the capital re-equipment includes the repair of the rafter system and the continuous 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 application the latest technologies... For example, if a soft roof is replaced with a metal covering. Here, the repair consists only in the dismantling of the roll 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 used equipment. In this regard, the repair of the roof structure of a one-story building is much cheaper. After all, almost everything construction Materials climb it 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 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 big mistake, which can lead to 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 \u200b\u200bthe 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 pie 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 so the estimate and the contract, the customer must understand them. That is, you cannot sign both documents without reading. Particular attention to the final amount. If it suits you, then there is no problem.
Even for a private house, you will need to make an estimate for the repair of the roof in order to know exactly what this work will cost and, taking into account your own financial capabilities, to choose the necessary materials. They also make an estimate for the repair of the roof and in any organization that has structures and buildings on its balance sheet.
Before making an estimate for repair work, you need to analyze the condition of the roof, measure the damage. To do this, an inspection report is drawn up, and after that the data is transferred to a defective statement, in which the necessary forthcoming work and their number, volumes of devices, materials, mechanisms are indicated. In addition to accurate calculations for the repair of the roof, the estimate has unforeseen costs.
Mandatory budget articles
In the first positions in the estimate, preparatory work is prescribed, which include: disassembling the roofing roll covering, which consists of several layers;
- disassembly of vapor barrier, insulation;
- dismantling the cement-sand screed;
- dismantling of wall gutters or water intake funnels;
- disassembly of parapets if necessary;
- dismantling of various abutments of rolled carpet to roof elements, etc.
After that, the estimate for the repair of the soft roof continues with positions for restoration work, which may include:
- installation of new parapets;
- primer treatment of the base;
- laying a vapor barrier, leveling screed;
- device of abutting the roofing carpet to vertical planes roof elements;
- laying insulation;
- restoration or repair of ventilation, chimney pipes;
- installation of water intake funnels or gutters;
- 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 includes a more extended list of works, large volumes, as a result, the cost of overhaul is several times higher than the cost of the current repair.
This will be accompanied by a list necessary materials for repair or construction, schedule of receipt of finance. When drafting contracts, this system greatly facilitates and simplifies 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 an hour later the estimate will be ready.
Any roof, be it on a private or apartment building, periodically in need of 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 of 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.
Mandatory items in the estimate
First of all, the estimate document always indicates the measures for removing the old coating, which are performed in several stages. This includes dismantling concrete screed, dismantling of insulation and vapor barrier, dismantling of parapets, if necessary, removal of gutters and water intake funnels, dismantling of 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 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
- Restoration 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 complete replacement some sites.
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:
- 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 be the starting point in creating an estimate for the overhaul of the roof.
- Estimated sheet for current repairs. Estimation 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 is involved in 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-complicated and non-hazardous facilities can be performed 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 nuances can significantly change the cost of work. These include:
- The area on which the work is to be carried out. Accordingly, the larger the damaged area, the more materials must be used and the work must be done.
- The cost of submissions in the market, which may vary depending on the supplier.
- Type of work performed: major or current repairs.
- Waste level of the material used to restore the roof.
- The need to use additional equipment, for example, for lifting or transporting.
In whatever house you live, 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,estimate for the repair of the roof.
Compilation procedure and questions that may arise
First of all, it is worth paying attention to what kind of roof repair is needed: soft, from corrugated board or metal, because the compilation 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?
- Creation of estimates for current repairs
Often, the preparation of estimates, as well as PPR, is carried out by a 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 worksfor which the company does not need to obtain an SRO admission. It contains current repairs and elimination of defects soft roof, roofs from metal, from 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 - 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 project documentation for this type of work.A prerequisite is the availability of an SRO permit for this type of construction work. Based on the design 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 a calculation is a defective statement, and in the case of a major overhaul - design documentation, which includes additional items (in particular, PPR, survey data, etc.). At the same time, you need to understand that the second option is more expensive than current repairs.
Estimates for repair work 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 installation of a vapor barrier, 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 \u200b\u200bthe 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 consumption rate 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.
