One of the most important parts of renovating your home is the process of reroofing. It's not a task that can be done quickly or without proper preparation.

Replacing the roof of your house requires a significant investment of both time and money, so it's crucial to be well-prepared.

When you begin planning for this project, there are several factors you need to consider. Firstly, you must decide whether you want to go for a complete roof replacement or just replace certain parts.

Additionally, you need to choose the right materials for your new roof. It's also important to have an idea of the average cost of roof replacement in Canada.

But don't worry! Here is a guide that will help you through all the essential aspects you need to know before embarking on the reroofing process for your home.

Factors that Can Affect the Cost

Here are some things that would help you decide to what extent you want your roof replacement to be done:

Full vs. Partial Roof Replacement

In most cases, reroofing refers to completely renovating your roof. This would be a good idea if your house is starting to get old or worn out.

A full roof replacement is also advisable when you have leaks or moulds that begin to be a matter of concern. This would definitely cost more.

If you're on a limited budget or if the roof replacement isn't urgent, check your roof condition. You might only need a partial replacement.

In some cases, only a roof repair is necessary. It would be impractical to do a full replacement if you only have minor leaks and issues.

A partial replacement can make all the difference if your roof is still in good condition.

Have a professional roofing contractor assess the condition of your roof to see whether you need a full or partial roof replacement.

Roofing Material

The average cost of roof replacement varies depending on the material you will use for your roofing. There are a lot of different materials available in the market today. Make sure you choose the one that works best for you.

Asphalt shingles have proven to be a good choice if you're on a budget. It is cheaper than most alternatives, but it is still durable enough.

Metal is one of the strongest materials to be used on a roof. It can withstand even extreme weather conditions. It's also easy to maintain and is designed to last for decades.

Slate roofs are a more eco-friendly and sustainable option. It also has a longer lifespan than asphalt shingles and metal. Do take note that it is the most expensive material.

Roof Size

Roof size directly affects the cost of a roof replacement. The bigger the roof area you have, the more you will have to spend. Also, more complex roof structures would cost more to replace than, say, flat roofs.

Damage Repairs and Removal Cost

When taking on a reroofing project, you would also need to account for the removal cost of your old roofing. Taking apart your old roofing also requires labour and thus adds to the cost.

Before a new roof can be installed in your home, you would first need to make sure that any damages on your roof are taken care of. Postponing damage repairs will be more harmful in the long run.

Average Roof Replacement Costs by Material

Here's an estimate of the roof replacement costs based on the price of the materials, basic labour, and the area of your roof. For now, let's say you have a 2000-square-foot roof area.

Asphalt Shingles

Asphalt shingles cost an average of $2.75–$5.75 per square foot. For a 2000-square foot roof area, the cost of the materials would only be around $5,500–$11,500.

Remember that this is one of the cheapest roofing materials out there.


Aluminum roofs cost an average of $7–$15 per square foot. In the example above, a 2000-square-foot roof would amount to $14,000–$30,000.


A metal roof costs about $10–$24 per square foot. Using this material for your new 2000-square-foot roof would cost you around $20,000–$48,000.

Slate Tiles

Slate tiles cost about $23–$38 per square foot. Using the example roof area above, slate shingles would cost you around $46,000–$76,000.

The better the quality, the higher the price. If you want a roof that stands the test of time, it's not a bad idea to invest in more expensive roofing materials for now.

Still, choose the ones that work the best for you and that serve their purpose.

How Much Will It Cost?

It would be hard to identify the specific cost for a new roof since it varies per situation. But here's a rough estimate of the ideal budget for a roof replacement.

Let's say the roof removal and roof installation both cost about $2 per square foot. Choosing asphalt shingles would amount to approximately $2.75 per square foot.

In a 2000-square-foot area, you would need around $13,500. But if there are still damage repairs that need to be done, the estimated cost could climb up to at least $15,000.

For the installation of a slate roof, the cost might go up to $8 per square foot. In this case, your total cost would be around $70,000.

How Long Does It Last?

According to 180 Contractors, asphalt shingle roofs last for about 15–30 years.

Metal roofs have a lifespan of 40–70 years.

Slate roofs have the longest lifespan of about 75–200 years.

It still depends on the climate of your area. A certain type of roofing material may corrode more easily in some areas than others.

Take a stroll around your neighbourhood to see which type of roofing is the best choice for your home.

Reroofing is a complex task that is best left to be done by professionals. Even so, you would still want to be involved in the whole process to make sure that the job is done to your liking.

Here's a guide on what to do before, during, and after your roof replacement.

Take note that roof replacements are most convenient to do in summer or spring. But if you ever find yourself needing a roof replacement in the winter, check this out. It may be more complicated, but it can be done with proper help.
