How much does a new roof cost?

Most often, customers begin their search with the question: "What is the cost of a new roof per square meter?"

In practice, there is no one universal price that would be applicable to all roofs. Two roofs with the same area of ​​120 m² can have completely different final values.

One may be a standard gable roof with easy access and few additional details. The other may have multiple slopes, hipped roofs, chimneys, skylights, dormers, large gables, and a complex gutter system.

Therefore, when determining the price of a new roof, not only the square meters, but also the actual architecture and complexity of the site must be considered.

When building a new roof, the following are usually calculated separately:

• the roof structure;
• the repair, strengthening or leveling of the structure;
• solid wood base or OSB when the system requires it;
• the vapor-permeable roofing membrane;
• the counterslats and the grill;
• thermal insulation, if provided;
• the roof covering;
• ridges, valleys and special coverings;
• the cladding around chimneys and skylights;
• headboards and headboards;
• snow retention elements;
• drainage system;
• the transport and loading of materials;
• the installation work.

Only after specifying these components can a real and detailed offer be prepared.

Sample approximate cost for installing a metal tile roof – 120 m²

Below is a sample indicative bill of quantities for the installation of a new metal roof with an area of ​​approximately 120 m² .

The indicated values ​​are indicative and refer to the installation activities in the specific example. The table aims to give a realistic idea of ​​what individual items can form the total price for installing a new roof .

Important: This is a sample bill for installing a metal roof with an area of ​​approximately 120 m². The indicated amount does not represent a universal price for all roofs. The quantities of the gutter system, end boards, sheathing, ridges, snow retention elements and other details are determined individually according to the specific project.

The bill does not include materials, dismantling of an existing roof, construction or replacement of a supporting structure, dense board cladding, thermal insulation, scaffolding, waste containers and other activities not explicitly described in the table.

What does the price of a new roof depend on?

Roof area

Square footage is one of the main factors, but the built-up area of ​​the house should not be confused with the actual roof area.

A house with a built-up area of ​​100 m² does not automatically mean a roof of 100 m². The slope, eaves, dormers and architecture increase the actual area of ​​the roof slopes.

Form and complexity

The easiest to implement are usually standard single-pitched and double-pitched roofs. More complex architecture increases the required materials, the amount of waste, and the installation time.

Gables, ridges, dormers, chimneys, eaves, skylights and various slopes require more special details and precise work.

Therefore, when searching for "new roof price per m²", it should be borne in mind that the square meter does not indicate the full complexity of the project.

Access to the building

The price is also affected by the ability of the materials to be delivered and lifted to the roof. In the case of tall buildings, narrow streets or limited access, the use of a crane, lifting equipment or additional scaffolding may be necessary.

Condition of the existing roof

In reconstruction, the exact cost can often only be determined after the old covering is dismantled. Beneath it, rotten beams, sagging, compromised connections and traces of long-standing leaks can be discovered.

How does the type of roof structure affect the price?

The supporting structure is the foundation of the entire roof. In new construction, it can be made of wood or metal profiles, depending on the project.

When reconstructing an existing roof, the condition of the rafters, capitals, Mauerlats and other load-bearing elements must first be established.

After dismantling the old coating, the following may be discovered:

• rotten wooden elements;
• serious sagging;
• insufficient reinforcement;
• traces of prolonged leaks;
• poor-quality previous repairs;
• incorrectly executed connections;
• displacement of structural elements.

In these cases, the structure must be repaired, strengthened, leveled or partially replaced before the installation of the new roof covering.

New roof with metal tiles – price and features

Metal tiles are a practical solution for both new roofs and the reconstruction of existing buildings. They combine a relatively low dead weight, quick installation and a wide selection of profiles, coatings and colors.

A properly installed system includes a quality roofing membrane, battens and grillage under the metal tiles. It is also necessary to ensure proper ventilation of the roof space.

When calculating the price for a new metal tile roof , not only the sheets but also all necessary accessories should be included:

• was also herbal strips;
• border and end plates;
• over-the-knee skirts;
• ulami;
• cladding around chimneys;
• snow retention elements;
• ventilation elements;
• seals and fasteners.

It is these additional items that are often overlooked when comparing offers.

New hipped roof – price

Recessed roofs are a preferred solution in contemporary architecture and for buildings that seek a clean and elegant look.

In the double-rebate system , the individual metal sheets are connected by specially shaped and tightly closed rebates. This type of roof requires very good preparation of the base and high precision during installation.

The final price of a hipped roof depends on:

• the type and manufacturer of the metal;
• the thickness of the sheet metal;
• the protective coating;
• the length of the sheets;
• the shape and slope of the roof;
• the base under the sheet metal;
• the type of membrane;
• the number and complexity of the cladding;
• the chimneys, the dormers and the skylights;
• the boards and hidden gutters.

With hipped roofs, the quality of installation is particularly important. The beautiful appearance is only the visible part of the system. Under the sheet metal, the foundation, waterproofing, ventilation and all connections must be properly implemented.

New roof with profiled sheet metal

Profiled sheet metal is a suitable solution for various types of residential, commercial, industrial and auxiliary buildings.

Depending on the purpose, different profile heights, sheet metal thicknesses and protective coatings are selected.

The price is usually more affordable compared to more complex roofing systems, and installation on a properly prepared structure can be relatively quick.

And with this type of roofing, the final cost should not be determined solely by the price of the sheet metal. It is necessary to calculate the fasteners, membranes, planks, sheathing, ridges, and the entire drainage system.

Roofing membrane and ventilation should not be underestimated

One of the most common mistakes when building a roof is to focus solely on the visible covering.

Under the metal tiles or other final coating is an entire system. A properly selected vapor-permeable membrane protects the structure and thermal insulation in the event of moisture penetration under the coating.

The counter battens create the necessary space for air to move. In a properly designed system, air should enter the lower part of the roof and be discharged at the top.

Therefore, when comparing offers, check what membrane is included, how the grill is implemented, and how ventilation is provided.

How do chimneys, skylights and dormers affect the price?

Each additional roof detail affects the cost and time frame. A large and relatively simple roof can sometimes be easier to install than a significantly smaller but complex roof.

Each chimney must be properly sheathed and connected to the roof system. Skylights require proper positioning, installation and precise execution of the details around them.

The ulams are one of the busiest sections because they collect water from two adjacent slopes. The more such elements there are, the more materials and work time are required.

Is the gutter system included in the price of the new roof?

The drainage system is not always included in the initially announced price. Therefore, when receiving a quote, you should explicitly check whether it includes:

• the gutters;
• drainpipes;
• the cisterns;
• the brackets;
• knees;
• the connections;
• the over-the-top skirts;
• the headboards and trim.

A new roof with an old, damaged, or improperly sized gutter system can cause problems even with the first heavy rainfall.

Repairing the old roof or building a new one?

The decision should be made after a professional inspection of the structure. If the problem is local and the supporting structure is in good condition, sometimes a partial repair is completely sufficient.

When there are multiple leaks, serious sagging, rotted elements, or the roof has been repaired multiple times without lasting results, building a new roof may be the wiser long-term solution.

The lowest initial price does not always mean the lowest costs over time.

What should a good quote for a new roof include?

When comparing quotes from different contractors, don't just compare the last line to the final price. Check in detail what you're getting for it.

Dismantling

It must be specified what exactly is being dismantled and whether the collection, removal and disposal of construction waste are included.

Roof structure

Check whether repair, strengthening, leveling or complete replacement of structural elements is included.

Roofing membrane

The offer must indicate what type of membrane will be used and how the connections and overlaps will be made.

Grill and ventilation

It must be described how the grill will be implemented and how air movement will be ensured under the roof covering.

Roofing

It is important to specify the manufacturer, model, thickness, protective coating, color, and warranty terms.

Trims and special details

Check whether chimneys, gables, gables, sides, ridges, skylights and other special elements are included.

Drainage system

It should be clear whether the drainage system is included in the price or calculated separately.

Warranty

Ask for clear information about the materials warranty and the warranty for the installation work performed.

Why is the cheapest price for a new roof not always the best choice?

In roofing, most errors are not immediately visible. An incorrectly executed detail around a chimney can start to leak water after a certain period of time.

Insufficient ventilation can gradually lead to moisture buildup. Poor-quality siding can cause problems in strong wind and rain, and an improperly prepared base can be visible even through the new coating.

Therefore, when choosing a contractor, it is wise to request not only photos of completed roofs, but also photographs and videos of the various stages of work.

Our completed roofs

When choosing a company for a new roof, the actually completed projects are much more informative than advertising promises.

At ROOFER - Center for Roofing Materials, we offer delivery of materials and complete implementation of various roofing systems.

We work with metal tiles, profiled sheet metal, retro panels, click panels and hipped roofs. Each site is considered as a complete system, not just a final coating.

It is recommended to show both the finished roofs and the preparation of the structure, the installation of the membrane, the construction of the grill, the design of the ventilation and the implementation of special details.

Video: how to build a new roof

It is not always easy for the client to understand what is behind the final price from just one quote. A video from a real construction site can clearly show the individual stages and the quality of execution.

The video can show the preparation and leveling of the structure, the installation of the roofing membrane, the double grill, the metal tiles, the gutter system, and the sheathing.

How to get an accurate price for a new roof?

For a preliminary calculation, it is necessary to provide as much information about the object as possible.

The most useful are:

• architectural project or roof plan;
• approximate area of ​​roof slopes;
• photos of the building and existing roof;
• location of the site;
• information whether the roof is new or existing;
• desired type of roof covering;
• information about chimneys, dormers and roof windows;
• preferred color and type of material;
• information about access to the site.

During reconstruction, an on-site inspection allows the actual condition of the structure to be determined. A significantly more accurate quote can then be prepared.
