Before Starting Your Roofing Renovation

If you're reading this guide, you've likely already thought about renovating or replacing your roof. Before diving into the hands-on work, it's important to properly organize your project. You’ll need to clarify your goals. People often underestimate the number of factors to consider during a roofing renovation project.

Of course, there are the materials installed on the surface, but also the structure’s shape, flashing, soffits, gutters, insulation materials, vents, and so on.

Key Words for a Roofing Renovation

Durable

In a perfect world, a roof should last a very long time. Depending on the material used, a roof can remain in good condition for many years—or even decades. So, when repairing or replacing a roof, it's important to choose a durable material and ensure that it’s installed professionally.

Well-Suited

There’s no shortage of options when it comes to roofing materials. However, rather than choosing based solely on appearance, it’s essential to review the specific characteristics of each material to pick one that fits your local climate, your ability to maintain it, and sometimes even your municipality’s bylaws.

What questions should you ask when planning a roofing renovation?

If you’re taking on a large-scale roofing project, it’s important to assess your needs carefully so you can choose the right materials and design the best possible roof for your home. If you don’t have much experience with roofing, it’s highly recommended to consult professionals early on—specialists in roofing, insulation, ventilation, soffits, and other related components.

Here are some criteria to consider when beginning your project:

• Ease of maintenance

• Value for money

• Insulation level

• Ventilation

• Environmental impact

How much does it cost to renovate, fix, or alter a rooftop?

Unless it’s a minor repair, it’s nearly impossible to renovate or replace a roof without spending a significant amount. We'll go into more detail about budgeting in another section of this guide.

First, you should get a general idea of how much you’re able to set aside for the project. You can consult our roofing price guide to see if your budget is realistic.

How often can I maintain my house's roof?

Some roofing types and materials require more upkeep than others. If you’re looking to keep maintenance to a minimum over the coming years, you’ll need to take that into account when designing your new roof.

It’s also worth remembering that roof maintenance must be carried out safely.

Is a roof restoration a good idea and worth it?

It may be more cost-effective to carry out repairs rather than a full replacement. To make the right decision, be sure to get advice from an expert.

Here’s an article to help you determine when it’s time to renovate your roof.

Will the entire roof structure need to be removed?

If you’re able to preserve part of the existing structure, you might be able to reduce your overall costs. However, if the entire structure must be replaced, you’ll need to account for demolition and the construction of a new base.

Is only part of the roof being renovated?

In some situations, it’s possible to renovate or replace just one section of the roof. This isn’t always an option, depending on the structure and materials involved, so be sure to discuss it with your roofer.

Will the new roof come with a warranty?

Your new roof may be covered by one or more warranties. Some contractors offer coverage for repairs or replacements over a few years.

There are also warranties for specific roofing materials. You’ll find detailed terms and conditions in the manufacturer’s official documentation.

To ensure your warranty is valid, always request written proof and keep records of the warranty terms.

Will the renovation impact my daily life?

Some roofing projects are completed quickly, in just a few days, and won’t significantly disrupt your daily life.

However, if you’re doing a full roof replacement, the project could take several days or even weeks. In that case, you may want to consider staying elsewhere during the work.

Could this renovation improve my home’s insulation?

One of a roof’s main functions is to help insulate and ventilate the home. If you’re currently facing insulation issues, this renovation is a great opportunity to improve it.

This could influence your choice of roofing material, soffit installation, flashing design, and even the overall roof structure.

Do I want to follow eco-friendly practices during the renovation?

More and more homeowners are looking to make environmentally responsible choices when it comes to materials and installation methods. Talk to your roofer and ask about the eco-friendly options currently available.

Do I need a permit for a roof renovation?

As always, it’s important to make sure you have the correct building permits for the work you’re doing. Some projects require a permit, while others don’t.

For roofing projects, you may need one depending on factors such as:

• Type of roof (structure, material, size)

• The city you live in

• Work methods used

Contact your municipality for details. Your roofer may also be able to provide guidance.

Common Types of Roofs

There are many types of roofing structures. In general, the most common include:

• Flat roofs

• Sloped roofs

• Mansard roofs

There are also rounded roofs, green roofs, and rooftop terraces. We'll cover the last two later in this article.

Within sloped roofs, there are subcategories like single-slope (shed), dual-slope (gable), and multi-slope designs. These are among the most common styles, especially in suburbs and small towns. In larger cities, flat roofs are more popular, using materials like TPO, EPDM, or multi-layer membranes.

To choose the best roof type for your home, consider your home’s size, weather conditions, budget, and aesthetic preferences.

Flat Rooftop Terraces and Green Roofs

Many people are now looking to turn their flat roofs into usable outdoor spaces, such as terraces or rooftop gardens. These options can provide added value by giving homeowners access to an additional area. Green roofs are eco-friendly and can be used to grow vegetables, while rooftop terraces expand your usable living space.

However, these are major projects that require thorough planning and budgeting. It’s essential to follow all the proper steps to ensure they’re feasible and affordable.

Roofing Components

While the outer layer is the most visible part of a roof, several other components play vital roles.

How to choose your roofer?

We’ve dedicated an entire article to this topic, but here are the basics:

These tips also apply to other contractors involved in the project (e.g., for gutters, ventilation, insulation, etc.).

Important:Always have a written contract with your contractors.

With your roofer, make sure the project complies with the building code and any local municipal regulations. When applying for a permit, ask if your city has specific rules for roofing.

What’s the best time of year to redo a roof?

In Quebec, spring and early fall are ideal for roofing work. Temperatures are mild, making it easier to install materials, with fewer risks of rain, extreme heat, or cold.

What financial aid is available for roof replacement in Quebec?

Depending on your situation, you might qualify for programs like Rénoclimat for energy-efficient renovations, or municipal grants for roof work. Check provincial and local programs before starting the project.

How often should you replace your roof?

• Asphalt shingles: every 20–25 years

• Metal roofing: every 50 years

• Elastomeric membrane (flat roofs): every 25–40 years

• Wood shingles: every 25–30 years

• TPO or EPDM: every 15–30 years

Regular maintenance extends your roof’s lifespan and helps detect problems early.

How to maintain your roof?

Some types of roofing need more upkeep than others. Here’s what maintenance typically involves:

• Regular inspections for damage or wear

• Cleaning to prevent water, snow, or debris buildup

• Replacing damaged sections (e.g., torn shingles)

Maintenance techniques vary depending on the roofing system. Speak with your roofer or the material manufacturer. Some roofs require annual snow removal as a preventive measure to avoid damage and extend their lifespan.

Quick Summary

By taking the time to assess your needs, choose the right professionals, and stay informed about building codes, you can ensure that your renovation is a success.
