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

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

Mandatory items in the estimate

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

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

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

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

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

The procedure for drawing up estimates

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

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

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

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

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

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

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

Apartment and private houses

Roof coverings can fail for a number of reasons, primarily:

• end of service life (natural wear and tear of the material);
• accidental mechanical damage to the coating;
• defects in roofing material;
• the result of incorrect 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 volume of work to be done. He will help you assess the required financial investments and draw up a detailed estimate. This approach allows you to optimize costs for emergency, current or major repairs.

Residents of apartment buildings should follow the same procedure, but the specialist assessing the damage must be a representative of the management organization responsible for the maintenance of the building. To call a technical worker to assess the condition of the roof, you must submit a written application to the management organization. A technical worker inspects the roof and apartments on the upper floors that have been damaged by rain or melt water, and records in detail all existing damage in the defect sheet. It is recommended to include photographs of the damage. The same document specifies the necessary measures to restore structures and the roofing pie.

The estimate for repairs is formed on the basis of the defective statement, so you should be very careful when filling it out.

Repair cost

The estimate for major roof repairs makes it possible to assess the level of upcoming financial investments and avoid cost overruns. The cost of planned roof repair work depends on the following parameters:

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

Drawing up an estimate requires a professional approach, since it is necessary to take into account the features of use and consumption when installing various materials. This makes it possible to avoid additional unforeseen expenses.

Budgeting

How to create an estimate for roof repairs? Usually, to draw up an estimate, a defect sheet is used with a detailed listing of the types and volumes of work required, the types and quantities of material required. An estimate is necessary to convert 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 standards numbers;
• names of works and costs for their implementation;
• units of measurement;
• number of units;
• cost of the unit of measurement (in rubles);
• correction factors;
• conversion factors;
• winter price increase coefficients;
• total costs (in rubles).

A sample estimate for roof repairs must contain an estimate of the cost of preparatory work. These may include:

• dismantling multi-layer rolled roofing;
• dismantling the screed;
• dismantling the thermal insulation and vapor barrier layers;
• dismantling parapets;
• dismantling the drainage system (wall gutters, drainage funnels);
• dismantling of roof connections to vertical structures.

• installation of parapets;
• treating the roof base with a primer;
• laying vapor barrier and heat insulation layers;
• screed arrangement;
• arrangement of junctions of the roofing covering to the vertical roof structures;
• installation of a drainage system;
• restoration or repair of ventilation and/or chimney pipes;
• installation of the final roofing covering.

The order of work depends on the type of roof and the type of materials used. Roof repair may involve restoration of the waterproofing layer and complete replacement of the finishing coating with a new one.

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

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

Mandatory items in the estimate

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

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

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

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

Budgeting

First of all, it is necessary to determine exactly what type of roof will be restored: soft, metal, corrugated or some other. This is necessary to draw up a document in an order that depends on the materials and technologies used for roofing work. For example, for the repair of a metal roof made of corrugated sheets, the estimate will indicate the replacement of metal sheets and accompanying actions. There will be no article on covering with a bitumen layer, since such a roof simply does not have it.

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

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

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

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

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

Factors affecting cost

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

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

Estimate for roof repairs: how to make your own

An estimate for roof repairs is needed when planning repairs to the roofs of apartment, industrial and other buildings, the maintenance of which involves accounting. A correctly drawn up estimate for major repairs allows you to calculate 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 repairs to the commissioning of the roof, adjusted for various factors that influence the completion time.

What does the repair estimate depend on?

Estimation is determined by the following criteria:

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

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

What does the estimate form take into account?

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

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

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

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

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

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

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

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

Let's sum it up

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

Whatever house you live in, private or multi-apartment, the roof periodically needs repair work. After all, damage to the coating can lead to damage to the rooms located below. And in order to begin repairs, it is necessary to first estimate their cost and consumption of materials. For this purpose, a estimate for roof repairs.

Procedure for compilation and questions that may arise

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

1. Creation of estimates for current repairs

Often, the preparation of estimates, as well as project planning, is carried out by a construction company or organization, which, in addition to determining the cost, has SRO approval. Although, regarding the last point, there is a clear indication that routine repair work that takes place at non-hazardous and technically complex facilities does not require SRO approval.

Repair of soft roof of a multi-storey building

Important!

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

In this case, estimates are drawn up on the basis of a defect sheet, which shows the degree of damage to the roofing.

Defective sheet for current roof repairs

1. Creation of estimates for major repairs

If major repairs are 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 SRO approval for this type of construction work. Based on the design documentation, which provides for technical inspections, the PPR is the starting point for creating estimates for repairs.

What must be included in the cost calculation?

The data for creating the calculation is the defective statement, and in the case of major repairs - 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 several times more costly than current repairs.

Estimates for repair work

Calculating the cost of repairing a corrugated roof often includes the following items:

• The preparatory stage, which will include work on removing corrugated sheeting, dismantling vapor barrier and insulation, parapets (if necessary), etc.
• The second stage is the restoration of the coating, which will include work on preparing the base, installing new parapets (if the old ones were dismantled), installing a vapor barrier, installing corrugated sheets, as well as restoration work with chimneys and ventilation devices.

Local estimate for roof repairs

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

Estimate for roof repairs

What will the final cost of the work depend on?

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

Cost estimate for roof repairs

The most “traditional” factors that must be paid attention to are:

• Area of ​​the room, roof. You need to understand that the larger the damaged surface, the more materials, worker labor and machinery will be involved.
• The estimate takes into account the rate of consumption of materials, but their cost on the market may vary, which also must not be lost sight of.
• Type of work: major repairs of both the roof and any other room will be much more expensive than eliminating several swellings.
• Waste level of the selected roofing material.
• The need to use lifting mechanisms and other machines (in buildings and structures with one floor they are usually not taken into account).

Estimate for roof reconstruction

It is quite difficult 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.

Estimate for roof repairs - a detailed plan for repair work

Important!

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

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