  • Asphalt shingles
  • Sheet metal and baguette
  • Flat roof (metal, concrete or wood) covered with:
    • Bitumen (asphalt) and multilayer gravel
    • Elastomeric membrane.


Type of roofing material

Price per square foot
Sample price of a roof renovation
Asphalt shingles $3 to $4.75 / sq. ft.
Replacement of 2,000 sq. ft. $5,000 to $8,000
Replacement of 3,000 sq. ft. $8,000 to $12,000
Metal sheets $4 to $15 / sq.
Sheet metal strips $15 to $ 26 / sq. Ft.
Replacement of 2,000 sq. ft. $25,000 to $30,000

Replacement of 4,000 sq. ft.


The above-mentioned prices are average price estimates. They may vary according to various other factors.


What can change the price of your roof renovation?

In addition to the cost of materials, the factors that can affect the cost of your roof renovation are:

  • The time it takes to complete your project:
  • The angle of the inclination of your roof
  • The frame (the number of slopes …)
  • The degree of complexity of the work
  • The extent of the surface of the slopes
  • Temperature
  • The time of the year (if the roofers’ schedules are full or not)
  • Your location
  • etc.

The lowest price for your roof renovation will usually be in the spring when the weather is good but most roofing contractors in your area would be fully-booked.

Further, it is advisable to avoid renovating your asphalt shingle roof between December 15 and March 15 as the shingle tapes stick less effectively when the weather is colder (or when it rains continuously, depending on the season. High winds could also cause them to be detached.


How to estimate the cost of the work yourself: measure the roof area

Would you like to see how a roofing contractor calculates the cost of the size of your roof for a future renovation? Depending on the configuration of your roof, we will show you how to calculate the price based on the size of your roof.

Taking measurements is the first and most important step in estimating the size of a roof.

Three solutions can be used to do this:


Les 3 techniques à utiliser pour savoir calculer ce que votre toit mesure chez Soumissions Maison.
Standing next to your house

Discovering the width and length requires the use of a tape measure.

However, if you have a pitched roof, you will need to use a ladder and a spirit level to measure the slope.

The measurements taken from the roof are often more precise than those obtained from the ground.

Analyzing the architectural plan Taking measurements from the plan is much simpler if you still have the building plans.
Up there on your roof

Use a tape measure and a diagram to take notes when you take your measurements.

Stay alert for the dangers of falling.

Perform this operation in dry weather with the help of a companion and decked out with slip-resistant shoes.


Depending on the type of roof you have, the calculation will be done differently.

Do you remember the popular formulas for calculating shaped areas in high school?

Get to work by first identifying the type of roof you have.

The types of roofs commonly found in Quebec


Le toit plat est un type de toiture retrouvée au Québec.

The flat roof may be substantially domed or have an incline of 5% or less, not to mention the existence of holes for draining.

It also allows the installation of a roof of plants which provides ecologically and aesthetically effective thermal insulation.

The shadow of the house is limited by the size of the roof. Thus, neighboring buildings can get closer.

A flat roof, due to future sealing problems, can never be complete.

It allows an ideal capture of sunlight if someone installs solar panels that are well- hidden thanks to the architecture that favors these types of installations.

  • This roof costs less maintenance and installation because it requires less material than a sloping roof. Further, it is a safer option than the sloping roof.
  • Solar panels can be grafted.
  • This roof gives the possibility of arranging a terrace or a garden including a barbecue or garden furniture, for example …
  • You do not lose any space because there is no loft or attic.


  • Melting snow in the spring or rainwater can be difficult to drain because of an absent slope.
  • Water infiltration or tightness problems can occur frequently.
Calculating the area of a flat roof
Pour calculer l’aire d’un toit plat chez Soumissions Maison, l’on utilise cette formule.

Today, rooftops or flat roofs are part of the familiar landscape in Quebec. The area without a slope is easy to calculate.

This calculation simply involves finding the area of a rectangle or square, or by multiplying the length of the roof by its width as shown in the image above.

Thus: A X B = area


Un toit mansardé, une autre possibilité de toit pour les partenaires de Soumissions Maison.
The Mansard roof

This type of architecture emerged under the reign of Louis XIV in France, in honor of François Musart, an architect who made this style of roofing popular.

A mansard roof represents a cross between a flat roof and a sloping roof. Thus, the roof covers the last floor of the house (the walls) or goes down.

It is also sometimes called a broken roof or attic roof.

An attic roof consists of a roof with 2 slopes with the lower part steeper than the upper one.

This declination of the roof often has recessed windows.

An attic is a part of a mansard roof with a low ceiling, a sloping wall, all under a broken roof.

This fenestrated space can be used due to its decent size.

  • An attic roof saves space by creating a new floor. These additional square meters in the house that do not encroach on the land represent a definite advantage.
  • This additional floor from an attic roof will benefit from a lower ceiling height. A classic floor offers more height.
  • The possibility of developing the attic remains a major advantage for shaping a new room with a roof of this type.
  • The addition of an attic, by its characteristics and architectural forms, can make the place unique. This landscaped space increases the value and character of your home. The value of the house increases significantly with the addition of an attic room. Indeed, you will only earn profits if your house goes from 3 to 4 bedrooms with this new addition if you decide to sell some day.
  • Another important benefit of a room in an attic roof is lower energy costs. There is not a lot of ventilation in an attic so this room retains heat. As a result, this room will not generate high energy costs and will stay warm in winter.
  • Many people consider the benefits of an attic room from an architectural point of view.
  • A mansard or attic roof will only create a very small room with little space. Thus, a few pieces of furniture can be used. In addition, once the furniture is set up, the space will become limited. This greatly reduces the full functionality of the room. New solutions exist, however, but they will require costs for the entire room to be developed. Children usually prefer these small rooms rather than elderly people who have difficulty moving up the stairs.
  • We must prepare a budget for windows and insulation. Ventilation is important to avoid musty odors. Mold and moisture have the potential to develop. In addition, as the heat increases, it is necessary to provide insulation that will prevent heat loss otherwise it will cost you more for heating.
  • Expect a major investment by choosing an attic roof if you plan to install a room. It is rather expensive to finish an attic. The foundation of the room or other parts of it may require serious renovations. Flooring for the room could be expensive, too. First, estimate the costs associated with this project before you get started.

Calculating the area of an attic roof

Pour installer un toit mansardé, on doit faire des calculs d’aire chez Soumissions Maison.

Attic roofs are really just a series of rectangles.

The calculation then becomes very simple. Just calculate the area of each of the rectangles and add them together.

Thus: (A X B) + (C X D) + (E X F) + (G X H) = area


Le toit en pente est une architecture de choix pour des jardins tel que vous le dira Soumissions Maison.
The sloping roof

The sloping roof is a massive architecture that gives it a standard, timeless, and traditional style.

This style has not experienced many changes from architects over time, even though the techniques and materials have really evolved since what would have normally allowed certain changes of the more traditional forms.

Rhythm could be affixed to a construction through ruptures in the lines and a different composition of the angular surfaces.

A layout of the attic room could satisfy many homeowners to add an otherwise useless and cold space.

  • This type of roof has a major advantage, that of facilitating the flow of ice, snow, and water using its slope. Recurring leakage disorders will occur less often as well as water infiltration.
  • Skylights create better lighting in your attic.
  • Such a roof makes it possible to arrange a wardrobe piece, a room, or a second room in the roof spaces in order to take advantage of this space.
  • Multiple materials are used to cover sloped roofs such as slate, wood shingles, asphalt shingles, or metal.
  • The sloped roof lasts longer than a flat roof and requires less maintenance.
  • This roof poses serious risks for accidents if you plan on doing its maintenance.
  • You will lose living space because of attic roofs.
  • This roof is more exposed to wind damage than a flat roof due to its greater surface area. Replacement or maintenance then becomes more expensive. A sloping roof does not only reflect the modern era but also traces of the past.
Calculating the area of a sloped roof
Le calcul afin de trouver l’aire d’un triangle pour un toit en pente avec Soumissions Maison pour votre toiture.

If you do not remember the formula for calculating the area of a triangle, here it is.

Use this formula for each triangle-shaped side and add all the areas.

To obtain the 4 surfaces of a four-sided roof, here is the method to follow:

Thus: A X B + ((C X D) / 2) + (E X F) + ((G X H) / 2) = area


You can now multiply this area by the unit cost of the chosen material to obtain an excellent estimate of the price associated with the coating.

When renovating a roof, why use a roofer?

Do you need a roof renovation? It is tempting to make a roof replacement DIY to save money.

However, it is advisable to leave roofing repairs or replacement to professionals as much as possible. This project is risky and dangerous and can have serious repercussions to your health and safety.

There are many advantages from hiring a professional roofing contractor:


Un couvreur employé est un atout quand vous refaites votre toiture et son revêtement.


Access to a roof: renovation of your roof has caused problems? If you employ a certified contractor, you will normally be entitled to compensation such as insurance or RBQ surety bonds. You will have no access to this if you do the work yourself.


Durability and warranty: Many roofers provide (in the long or short term) warranties for the work done. Contractors want to stay in your good graces with quality work to ensure your satisfaction because they also benefit from customer referrals.


Their experience: Throughout his career, a master roofer has had the time to become familiar with many types of roofing and problems that may arise. Thus, he and his team will know the suitable roofing materials for your home and repair or replace it efficiently.

Tips for finding the best roofing contractor

There are many materials and types of roofs available in the market. However, make sure your roofer knows how to install what you have selected.

Is your faucet is leaking? Do you need a floor renovation, lighting upgrades, or is your roof sinking?

Our network presents you with all the opportunities to hire a specialized contractor to solve your problems. But who to choose among the various possibilities to ensure you choose the right person?

Here are 5 useful steps you can follow as a very convenient guide:


Does he take the time to inspect your roof properly?

Make sure your home is carefully examined and its peculiarities understood by the contractor.Even if your roof is old, it does not necessarily need a complete overhaul so do not order a replacement without knowing the origin of the problem.The presence of big ice cubes, for example, indicates a clear problem with condensation that should be resolved.A visit of the attic may be required for the roofer to detect potential problems.Also, remember to have the condition of the roof deck examined.

Is the roofer competent?

Find a competent roofer for the replacement of your roof.The type of roof chosen determines the necessary accreditation from suppliers (materials) for the roofer.

Companies offer contractors free training and accreditation with required examinations. Customers must learn about the materials and products that the contractor prefers, as products from different manufacturers do not all fit together.

In the case of a type of membrane or shingle, contractors should generally opt for products of the same category.


What are the signs of damage discovered by the roofer? 

Insufficient roof insulation will cause the accumulation of too much heat
, which, in turn, will cause asphalt shingles to roll up depending on the roof.Issues at the top are easy to spot.A roof can be degraded due to environmental factors such as hail, water, cold, frost, sun or wind. These problems are easily detected.The accumulation and growth of lichen or mosses on the shingles results in a loss of permeability because the surfaces become porous more quickly.Asphalt shingles that have darkened in color, with loosened fasteners, and rust on the sheet metal are signs of wear that should be checked from time to time. These warning signs may indicate water infiltration. 

What are the warranties offered by the contractor?

An accreditation from the materials’ supplier allows the contractor the opportunity to provide additional warranties to his clients.

Be sure to look at the bills of materials so that your shingles deemed guaranteed for 50 years are guaranteed for all this time.

The AMCQ Quality Assurance Program offers a 10-year guarantee (in total) for its member contractors.

The AMCQ which complies with the requirements of the Civil Code is jointly responsible with the contractor (roofer) from the initial 5 years and provides an extra 5 years additional.


Is the roofer safe?

Does your roofer do his work directly under the sun when the shingle softens?

➢ Does he collect the waste and loose nails resulting from his work?

➢ Does he have a protection plan for your cars to prevent breakage during the operation?

Do not worry, however. Doing business with a member contractor of the ACMQ (Association of Master Roofers of Quebec) means that the roofer can take advantage of insurance (civil) amounting to 5 million if an accident occurs. Moreover, their employees take mandatory and preventive training courses. 


How to recognize the signs and when is it time to renovate your roof?

Do you think your roof needs a renovation?

Have it evaluated every year (recommended time) if it is over 20 years old.

You will see listed below the signs that indicate an imminent replacement of your roof.

It is essential to preserve and renovate your home, especially to maintain or increase its value, but most especially because it represents the ultimate investment for a homeowner.

Conduct a thorough inspection.

An annual inspection is necessary to ensure the constant good condition of a roof to locate possible damage.

Once the cold season is over, get on your roof to take a closer look at your roof.

Wait for the ice and snow to melt before starting the process, both for your safety and for the efficiency of the operation.

Take this opportunity to note the elements that seem wrong. This will ensure that the roofers or contractors contacted will take them into account in the quotes they will provide to you.

If problems persist every year, it will be a question of completely resolving the problem with a roof replacement or repair of elements such as insulation, ventilation, etc.


Il est important de vérifier votre toit efficacement pour qu’un maître-couvreur ait la meilleure idée des réparations à faire chez Soumissions Maison.
Once both feet are well perched on the roof, watch for cracks visible to the naked eye.
Seal them (if applicable) as soon as possible to reduce the potential for serious damage.

Take the opportunity to check your plumbing column and drain. A specialized plumber could work at the same time to make sure the plumbing column is working as it should.


Unfortunately, a material has a limited life. For example, you will need to inquire about the date of your most recent roof renovation to find out about the next renovation opportunity.

Renovating your roof should cost you at least $5,000 and up to $ 10,000. This amount varies depending on the type of material selected.

Since the roof is very important for a quality home, the expense will seem expensive but this investment is important.

Do not worry about investing properly in a roof to achieve a sustainable result; this process happens rarely anyway.

For more information, see the inspection report of the home pre-purchase. This document may reveal components to be verified that contractors should be aware of during the inspection to better reflect this.

The materials used during roof renovations will depend on your budget for the work, the configuration of your roof (flat or sloping), and its dimensions.

Above all, however, recognize the signs and cues of a roof that requires repairs or a total change.


Here are 4 obvious signs that your roof needs to be renovated

Des bardeaux qui sont déplacés sont un signe que la toiture doive se faire rénover.


When you see displaced shingles on your roof, call an expert to make a damage report and suggest modifications to renovate.

If you spot damaged shingles, take action promptly.

Various factors can cause such deteriorations as a storm or the effects of extreme weather.

Contact a specialized roofer to clear any doubt in your mind.

Si vos plafonds font passer l’eau qui coule de votre toiture, des rénovations sont nécessaires.


If brown spots appear on your ceiling, it could be a bad sign that indicates an imminent major renovation.

You will have to question whether your roof is performing its functions or not.

If the water has managed to make its way to you from the cracks on your roof, there is indeed cause for alarm.

A meeting with a roofer is necessary for this one to determine the best solutions.

Des gouttières qui sont pleines de débris disent haut et clair que la toiture est due pour être changée. INSPECT YOUR GUTTERS

Inspect the gutters. If you find shingle debris frequently, it does not bode well.The older they get, the more shingles break up in pieces due to a variety of factors.These bits of pieces found in large quantities in your gutters indicate that a change or renovation of the roof is required.If you do not get it done as soon as possible, you risk further degradation.
Un vieux revêtement doit être changé après un certain nombre d’années, même s’il a toujours bien assuré.


Depending on the age of the roof, you should always plan possible renovations.

A roof survives on average from 20 to 25 years depending on the roofers.

It could last even longer if you or someone else has done renovations or proper maintenance over the years.

Roofs do not always undergo the same physical requirements.

However, even a roof installed 20 years ago in perfect climatic conditions or laying requires at least a good regular inspection by a professional in the field.

You will see below various types of coverings as well as their major characteristics.

Your roof, as your protector against bad weather and the cold, is an essential part of your home.
